juyterman1000/entroly Auditable context control plane and MCP server for AI coding agents. Compresses context 70–95% (BM25 + entropy + dep-graph knapsack), stabilizes prompt prefixes for provider cache discounts, routes easy tasks to cheaper models (RAVS Bayesian router), and verifies answers locally with WITNESS hallucination guard (0.844 AUROC, $0, ~3 ms). MemoryOS adds local budget-aware working/episodic/semantic memory with decay, safety scanning, and durable persistence. 38 agent integrations (Cursor, Claude Code, Codex, Aider, and more). Ships as MCP server (entroly serve), HTTP proxy, or Python/Rust library. Apache-2.0, local-first. pip install entroly
Eszetael/postgres-mcp-hardened Maintained Rust replacement for the archived @modelcontextprotocol/server-postgres. Writes are refused twice: sqlparser AST validation rejects mutating statements before execution, and the session runs defaulttransactionreadonly with a per-session statementtimeout — so the read-only transaction is the fallback, not the only defence. Single self-contained binary, stdio and Streamable HTTP, schema inspection, column redaction that survives renames and casts, an EXPLAIN cost guard, a hash-chained audit log with --verify-audit, optional OAuth 2.1 RS256, distroless image, signed releases for five platforms. MIT.
vornicx/Midas Local-first memory for long-horizon AI agents with no LLM at ingest — $0 per message, zero data egress, verbatim source-traceable recall. Typed belief revision, selective forgetting, and a provenance guard that blocks memory-justified destructive actions unless user-confirmed. One midas init wires Claude Code, Cursor, Codex, and 6 more clients to one shared SQLite memory; local web inspector and hash-chained audit log. Benchmarked on LongMemEval/LoCoMo/BEAM with one-command repros — including published negatives. uvx midas-memory-mcp or npx -y midas-memory-mcp
Vasilispapg/claude-handoff Post-hoc session handoff and project memory for Claude Code: turns any session transcript — including crashed or usage-limit-hit ones — into one clean handoff.md another model continues from (ChatGPT, Gemini, or the next Claude), and distills a project's ENTIRE session history into one cited memory brief injected at every session start. MCP tools listsessions and handoff (LLM summaries only behind an explicit --allow-llm); zero dependencies, pure stdlib, secrets redacted from every output. pipx install claude-handoff, then claude-handoff --mcp.
ni-c/wikijs-mcp Search, read and edit a self-hosted Wiki.js 2.x, plus its assets, comments, users and groups (62 tools). Wiki.js' default search engine indexes only titles and descriptions, so searchpages names the active engine and greppages searches what is actually written in the pages. updatepage compares against the moment you read a page and refuses to overwrite an edit saved in between; surgical find-and-replace must match exactly once. Read-only mode, a write path scope, and confirmation tokens on everything destructive. npx -y @ni-c/wikijs-mcp
Battam1111/Myco Agent-first cognitive substrate with 18 manifest-driven verbs (germinate / eat / assimilate / sporulate / traverse / immune / molt / …) and 25 lint dimensions enforcing contract invariants mechanically (R1–R7). Cross-session / cross-project memory via a self-validating filesystem graph — AST + markdown-link derived, not embedding-based. Provider-agnostic by design: MP1/MP2 dims forbid LLM-SDK imports in the kernel and plugin tree. Editable-default install. Works with Claude Code, Cursor, Windsurf, Zed, VS Code, and any MCP client.
vishalbanwari26/mnemos Persistent memory with three swappable storage backends (Postgres/pgvector, Qdrant, Neo4j) behind one interface, benchmarked head-to-head for latency, not just claimed interchangeable. Retrieval weighting adapts per user via epsilon-greedy over real outcome feedback instead of a fixed formula. Reflection merges near-duplicate facts and decays/archives stale ones, audit-logged, never hard-deleted. Real before/after MCP eval: +60% answer accuracy with memory vs. without. git clone + uv sync (not yet on PyPI).
FROWNINGdev/django-orm-lens Django ORM static-analysis MCP server. Nine read-only tools (listapps, listmodels, describemodel, findrelations, cascadepreview, erdiagram, describemigrationdependency, suggestindexes, signalgraph) that expose Django schema, relationships (FK/M2M/O2O, ondelete, relatedname), migration deps, missing indexes, and signal graphs — no DB, no Django boot, no credentials. Companion to a VS Code / VSCodium / Cursor extension (Open VSX verified) and a django-orm-lens PyPI CLI. pip install django-orm-lens[mcp].
vishnu-77/openreflex Local execution memory for AI coding agents (Claude Code, Codex CLI, Cursor, OpenCode). Lifecycle hooks record coarse task metadata into a SQLite Experience Graph (no code, commands, tool output or transcripts, and no model calls). Before a similar task it injects what worked, the relevant files and known fixes with an execution budget; during a task it recommends whether to continue, pivot or stop. MCP tools cover execution context, progress checks, outcomes, search and explanations.
oomkapwn/enquire-mcp Long-term memory for AI agents (Claude Code/Desktop, Cursor, ChatGPT, Codex, OpenClaw) backed by a local Obsidian markdown vault. Hybrid retrieval (BM25 + ML embeddings + BGE reranker, RRF-fused), HNSW + int8 quantization, agentic RAG (HyDE + sub-question), GraphRAG-light (Louvain wikilink community detection), standalone Obsidian Bases, PDFs + Tesseract OCR. 46 tools, 19 MCP prompts, MIT, SLSA L2, zero cloud calls during serve. npx -y @oomkapwn/enquire-mcp serve --vault <path>
TT-Wang/cortex-plugin Persistent, self-evolving memory plugin for Claude Code. Background miner extracts durable lessons (decisions, conventions, bug fixes) from completed sessions via Claude Haiku, stores them as human-readable markdown in an Obsidian vault, and assembles query-tailored context briefings at session start. Local-first, no cloud, no API keys. Self-healing install via uv bootstrap shim, /cortex-doctor preflight, graceful FTS-only degraded mode when claude CLI missing. MIT.
dahshanlabs/klypix-mcp Shared, versioned project brain for coding agents: one brain.klypix file committed with the repo holds current decisions, corrections that supersede (archived, never deleted), evidence anchors that flag drift when cited code changes, and open questions. Sessions declare their task and files and are warned about exact-file overlap. Lifecycle hooks for Claude Code; MCP config + rules for Codex, Cursor, Gemini CLI, Cline and Copilot. npx klypix-mcp install
Evan-Crx/permisapi-mcp 7 tools for French open-data building permits (Sitadel, 311k rows, ~2M permits/year, Etalab license). Search, details, DVF transactions cross-ref, real estate dealer opportunity score, PLU urban zoning, BRGM natural and technological risks, and a Vue 360 composite that fans out 6 sub-fetches in one tool call. Powered by permisapi.fr. Plan Free covers basic search and details, Pro+ unlocks the enrichments. Install: pip install permisapi-mcp.
SVerITG/Metis A private, local research "second brain" for Claude: project-aware memory, cited answers from your own library (won't invent what it can't find), linked notes/meetings/ideas via a domain-specific knowledge layer, daily briefs (news + new papers in your field), a live meeting assistant, cross-pollination across your work, and 34 routed agents. A governed layer between you and the AI, with guardrails like data protection. A Research Cortex.
AkashGoenka/coldstart Codebase memory for coding agents, with no embeddings and no API key. A deterministic AST index answers "which files are relevant to this task?" in milliseconds, and agents write durable notes about the repo that are content-hash checked — a note flags itself stale the moment the code it describes changes. Notes are markdown inside the repo, so they commit and review alongside your code. npm i -g @cstart/coldstart && coldstart init
CodeAbra/iai-personal-memory-engine Local memory daemon for any MCP-over-stdio client with three-tier storage (episodic/semantic/procedural). Own SQLite + hnswlib store (Hippo) with bge-small-en-v1.5, MIT-licensed community-detection reranking (MOSAIC), and sleep-cycle consolidation. AES-256-GCM encrypted at rest, no telemetry. Verbatim recall >=99% and post-contradiction Rescue@10 1.000 at honest scale. Ambient capture via shell hooks. Windows support in beta.
dbwls99706/deadends.dev Structured knowledge of what does NOT work. 2,400+ entries across 54 domains record the dead ends for an error - the fix that looks right and fails, and why - alongside workarounds with success rates and an error transition graph. Covers code errors and country-specific real-world rules (visa, banking, legal, emergency) where generic answers are most often wrong. pip install deadends-dev, or hosted at https://deadends.dev/mcp
DomDemetz/claude-soul Self-improving learning engine for Claude Code. Extracts signals from every session (corrections, successes, confusion), runs periodic reflections, and evolves behavioral frameworks through evidence tiers (hypothesis → observed → validated). Frameworks that keep working get promoted, bad ones get retired. 9 MCP tools, automatic hooks, phase-adaptive learning. Single dependency, local-only. npx claude-soul init --starter
wenb1n-dev/SmartDBMCP A universal database MCP server supporting simultaneous connections to multiple databases. It provides tools for database operations, health analysis, SQL optimization, and more. Compatible with mainstream databases including MySQL, PostgreSQL, SQL Server, MariaDB, Dameng, and Oracle. Supports Streamable HTTP, SSE, and STDIO; integrates OAuth 2.0; and is designed for easy customization and extension by developers.
DanceNitra/inspeximus Persistent agent memory with a first-class correction channel: supersede or revert a fact so recall stops returning the stale value, an echo guard that blocks a restated old value from resurrecting it, and receipted erasure (a signed, content-free tombstone that makes a deletion provable). No LLM on the write path, zero dependencies, the core in one file, 73 MCP tools. uvx --from "inspeximus[mcp]" inspeximus-mcp
Mnemosyne-OS/Mnemosyne-Neural-OS Memory the human governs: vaults separated by domain (code, notes, journal) on your own machine, hybrid retrieval (BM25 fused with vectors by RRF), and a declared vault list, so a vault left out cannot be read by mistake. Also reads what the OTHER coding agents on this machine wrote to disk, and flags when two are live in the same git worktree. Needs the Mnemosyne OS desktop app running. npx -y @mnemosyneos/mcp
Kemetra/seshat-bi Read-only readiness governance for BI pipelines. Six tools report where each table sits across a seven-stage source-to-Power-BI spine, explain what is blocking the next stage, run a static SQL/TMDL/PBIR governance check, and export an evidence pack. Tools never write files, execute warehouse work, or grant approvals -- human sign-off stays a separate seam. Install: pip install "seshat-bi[mcp]" then seshat mcp.
gingugu/gingugu Persistent memory for AI coding assistants. Local SQLite, no cloud. 16 MCP tools: store, recall, search, relate, consolidate, export, and credential vault (OS keychain). Typed memories with confidence lifecycle (verified/inferred/stale/deprecated), namespaces, knowledge graph, and hybrid BM25 + semantic search via fastembed ONNX. Works with Cursor, Windsurf, Claude, and any MCP client. pip install gingugu
gulmezeren2-byte/erp-report-engine Read-only MCP over the SQL database behind an ERP (Logo Tiger, Netsis, Mikro). The agent sees canonical entities like orders, never raw ERP tables, through a four-layer read-only guard that checks the statement, fails closed, and blocks side-effecting functions (pgreadfile, xpcmdshell, …) — measured by a public 28-attack benchmark and an in-browser "break it" playground running the real guard via Pyodide.
Piccolo123/url-manager-mcp Agent-first cross-platform bookmark & knowledge manager. AI agents collect web pages from any source (pairs naturally with Fetch, Firecrawl, Brave Search) and auto-categorize into organized collections with search, tags, and shared folders. 16 tools including agentregister (zero-config onboarding), addfootprint, searchfootprints, createsharedcategory. pip install -r requirements.txt && python server.py
yakuphanycl/instinct Self-learning memory for AI coding agents. Observes tool sequences, user preferences, and recurring fixes; confidence-based promotion (hits ≥5 → mature, ≥10 → rule) so agents stop repeating mistakes without explicit instruction. SQLite-backed, project-aware, zero external deps. Works with Claude Code, Cursor, Windsurf, Goose, Codex. Published on PyPI as instinct-mcp and registered in the MCP Registry.
ckanthony/Chisel Reduce context usage on file use. Send only unified diffs instead of full files (up to 20-100× fewer tokens), and read large files with targeted grep/sed instead of full reads (up to 500×). Kernel-enforced path confinement hard-locks the agent to a configured root: no accidental reads or writes outside scope. Standalone for your file access or embed in any MCP server (Rust, Node.js, Python via WASM).
kunwar-shah/claudex Persistent memory + FTS5 full-text search for Claude Code conversation history. Indexes ~/.claude/projects/ JSONL into SQLite, exposes 10 MCP tools (store/recall/search memories, list sessions, get summaries) plus prompts. Includes a web UI for visual exploration with themes and exports. Works with Claude Code, Cursor, Codex, Windsurf, and any MCP-compatible client. npm install -g @kunwarshah/claudex
yubinkim444/repo-memory Shared, git-tracked memory for AI agents on the same codebase. Stores facts/decisions/gotchas in a .ai-memory/ directory you commit to the repo — sync is git, no DB, no daemon. What one Claude/Cursor/Cline learns, the next one picks up automatically across users and machines. 5 MCP tools (getrepomemory, addfact, listfacts, adddecision, addgotcha). Install: uvx repo-memory-mcp --repo /path/to/repo.
dfrancislyondflabc-tech/agentic-recall Long-term memory across sessions over a folder of plain markdown files. Hybrid retrieval (BM25F + dense vectors + phrase proximity) with an explicit absence verdict: when the corpus does not hold the answer it returns no results and names the query terms that appear nowhere, instead of ranking a least-bad match as though it were one. Embedding model runs locally, nothing leaves the machine. MIT.
Agaveis/hiberden-mcp Read and verify your local media-archive catalog from an AI assistant: 3-2-1 coverage across disk, NAS, S3-compatible cloud, and LTO tape. Verifies a copy by physically reading it back and re-hashing it against the source; catalog-management and delete tools are off by default. On Windows it installs as a signed Desktop Extension (MCPB); on Linux the same connector ships as a standalone binary.
syndicalt/zaxy Event-sourced agent memory on a hash-chained append-only log with an embedded temporal knowledge graph (Kuzu, no sidecar). Cited Memory Checkout context, salience-based forgetting that attenuates instead of deleting, compaction-recovery hooks for Claude Code, token-budgeted checkout, and review-gated consolidation. 47 MCP tools with an 8-tool core profile default. pip install zaxy-memory Docs
liza-studio/skillmem Self-improving skill memory for coding agents: skills that help get reinforced, unused ones fade on an Ebbinghaus decay curve. $0 write path (SQLite FTS5 + local ONNX embeddings, no LLM calls), bilingual EN/RU hybrid search, SHA256 tamper-evident history, deterministic LongMemEval benchmark in-repo (hit@5 0.871). 8 mem tools; deep Claude Code hook integration optional. pip install skillmem
stevepridemore/graph-memory Personal knowledge graph for Claude on Neo4j. Typed entities (Person/Project/Decision/Preference/Concept), bi-temporal edge validity (validat/invalidat), per-type weighted decay, contradiction detection, and a nightly "dream" extraction process. Local bge-small-en embeddings, no API keys. Optional OAuth 2.1 + Cloudflare Tunnel for cross-device use across Claude Code, Desktop, web, and iOS.
DollhouseMCP/mcp-server One-line installable MCP server that adds reusable customization elements — personas, skills, templates, agents, memory, and ensembles (collected customization tools) — to any MCP Client application. Dynamic permissioning for safe AI operations, a robust validation architecture, versioning, and a public collection of shareable content. Install: npx @dollhousemcp/mcp-server@latest --web.
SAIHM-Admin/saihm-mcp-server-pro Client-side-sealed persistent memory for AI agents. Cells are encrypted in-process before they leave, so the endpoint stores, anchors, and shares over ciphertext and never holds your keys. Post-quantum ML-DSA-65 identity and ML-KEM-768 authenticated sharing; forget crypto-shreds the wrapped key for GDPR Art. 17 erasure. Eight MCP tools. Apache-2.0. Install: npx -y @saihm/mcp-server-pro.
slotix/dbconvert-streams-public Read-only SQL across PostgreSQL, MySQL, S3-compatible buckets and folders of Parquet/CSV/JSON — and one query can join across all of them, federated in-process by DuckDB. No tool writes: they are absent rather than disabled, and every tool declares readOnlyHint. Runs from connection strings alone as docker run -i --rm slotix/stream-mcp postgres://… or as a one-click Claude extension.
gura105/operational-ontology Reference implementation of an "operational ontology": MCP tools are generated from a typed business domain model (objects, links, actions) — one tool per query shape and per action, deliberately no raw SQL tool. Writes pass business-rule preconditions, are audited, and write back to the systems of record; refusals are machine-readable. Demo scenario included (pnpm demo / pnpm mcp).
STiFLeR7/memex Developer context continuity system. Watches your git repos and builds a temporal knowledge graph of modules, symbols, decisions, and open problems via Graphiti + Neo4j, then serves it to any AI coding agent over MCP. Every edge carries a validity window and a confidence score that decays over time. 12 tools across read and write. Install via npx -y stifler-memex-mcp. MIT licensed.
pjpoulose/PIL Personal Instagram Library: turns your Instagram saved posts into a private, AI-searchable knowledge base on your own machine. Vision-AI deep reads (summaries, key points, how-tos, links, tags) go into local SQLite, queried live through a read-only stdio MCP server by Cursor, Claude Code, and Claude Desktop — or as a static export for any AI tool. Code is shared, data stays home.
laradji/deadzone Local-first semantic search over library docs. Single Go binary, MCP stdio, vector index pinned to the binary version. Like Context7 with the internet off. Pre-built index DB auto-fetched on first launch and SHA256-verified, then zero network. Also available as docker run --rm -i ghcr.io/laradji/deadzone server. Listed in the official MCP Registry as io.github.laradji/deadzone.

Install: npx -y greencalculus-mcp, or connect remotely at https://mcp.greencalculus.com. Free tier, no card.
khwanlabs/khwan-mcp Durable memory for coding agents, built around corrections. Captures the moment you correct the agent as a typed event and distils it overnight into a standing rule the next session starts with, rather than only extracting facts. An isolated brain per project instead of one blended profile. Recall and record make no model calls — your client is the model. pip install khwan-mcp
SaravananJaichandar/world-model-mcp Temporal knowledge graph for codebases. Captures decision traces, links test failures to code changes, learns co-edit patterns, predicts regression risk, and enforces learned constraints at the edit boundary via a PreToolUse hook. 22 MCP tools, 9 SQLite databases with FTS5, supports Python/TypeScript/JavaScript/Solidity/Go/Rust/Java. Install via pip install world-model-mcp.
jeremiahsay/greencalculus-mcp Sourced greenhouse-gas emission factors and audit-traced carbon calculations (activity, embodied EN 15978, PCAF financed emissions) — every value returns with its exact source cell and data version, so answers are citable and reproducible. 13,000+ factors, 11 tools. Install: npx -y greencalculus-mcp, or connect remotely at https://mcp.greencalculus.com. Free tier, no card.
Abhigyan-Shekhar/Waggle-mcp Persistent graph memory for AI agents. Drop a conversation turn in via observeconversation() and facts are auto-extracted, stored as typed graph nodes with local semantic embeddings (no API key). Supports temporal queries ("what did we decide last week?"), conflict detection, and context priming. One-command setup with waggle-mcp init. SQLite locally, Neo4j in production.
rwnalds/engram Second brain your agents read and write, over a git-backed markdown vault. Authority-aware search ranks superseded and archived notes below live ones (from frontmatter, no vector DB), so agents quote the current doc, not the dead one. Per-agent read-only or write tokens, a git audit trail of every change with diffs, a knowledge-graph dashboard, and Obsidian compatibility.
HBarefoot/engram Local-first persistent memory for AI agents. SQLite + local embeddings (all-MiniLM-L6-v2), hybrid semantic + FTS5 recall, secret detection, and contradiction handling. 6 MCP tools (remember, recall, forget, feedback, context, status) over stdio.

Works with Claude Desktop, Cursor, Windsurf, and any MCP client.
thomasjumper/agentbay StremAI: shared memory for AI coding agents. What one agent learns, every agent recalls, across sessions, machines, and tools. Per-agent attribution, provenance, and export, so you can see which agent learned a fact and whether it has been verified. Remote Streamable HTTP with OAuth, stdio fallback. claude mcp add --transport http stremai https://stremai.com/api/mcp
ctxfile/ctxfile Local-first MCP server that snapshots your project's working state — files, git, plan, and decisions — into one structured context object and hands it to any MCP client in a single call. Save a session in one agent, continue it in another. Zero network calls by default; read-only over your project. Works with Claude Code, Cursor, and any MCP client. npx -y ctxfile
dimitar-grigorov/mcp-file-tools Filesystem server for legacy, non-UTF-8 files. Auto-detects and converts 24 encodings (CP1251, CP1252, ISO-8859-x, KOI8-R/U, GBK/GB18030), keeps each file's original encoding on write, and manages BOM and line endings. Encoding-aware grep, partial reads with offset/limit for large files, and allowed-directory confinement. Single Go binary, no runtime dependencies.

JinyangWang27/people-context Local-first memory for AI agents about the people in your life: explainable identity resolution, relationships, roles, facts, interactions, reminders, and communication guidance in one SQLite file you own. Imports are review-gated, sensitive disclosure is operator-gated, and ordinary operation makes no network calls. uvx --from people-context people-context
atakanelik34/Bilinc Hosted agent memory that keeps an audit trail. Three tools — commitmem, recall, status — where each write carries provenance (which run, tool, or operator produced it), contradictions with prior state surface as inspectable changes rather than silent overwrites, and a bad run is recovered from a snapshot instead of repaired by hand. pip install -U bilinc
vbcherepanov/total-agent-memory Persistent local memory for coding agents: temporal knowledge graph with fact invalidation, procedural memory, episodic recall, AST codebase ingest and cross-project analogy. 74 tools, 9 IDEs, and zero LLM or network calls in the default hot path.

Indexes commits, PRs, Jira/Linear tickets, Confluence docs, Slack threads, and Calendar events into SQLite + FTS5 + on-device ONNX embeddings; exposes 15 tools, 3 resources, and 3 prompts so Claude Code, Cursor, and Codex can search and cite your past work. brew install --cask pavelpilyak/devrecall/devrecall
flexorch/flexorch-mcp Convert unstructured business documents (PDF, DOCX, invoices, contracts, payroll) into structured, LLM-ready datasets with automatic classification, field extraction, PII masking (10+ locales), and quality scoring. 6 async MCP tools covering the full pipeline: submit → poll → extract → build → export JSONL/RAG/CSV. Install: pip install flexorch-mcp.
afairai/afair The open-source, self-organizing memory for all your AI tools. Three frozen verbs (remember/recall/observe); background agents extract entities, resolve conflicts, consolidate and decay, so the vault structures itself instead of only storing. Append-only, content-addressed, encrypted (SQLCipher), single-tenant, self-hostable. uv run python -m afair
kage-core/Kage Verified, git-native memory for coding agents. Memory is plain JSON packets committed in your repo, each checked against the code it cites — hallucinated citations rejected at write, stale or changed memory withheld at recall, plus diff-time stale-catch. Local-only (BM25 + vectors), no account, no API key. npx -y @kage-core/kage-graph-mcp install
ezpzfile/ezpzfile-mcp Read and convert documents (PDF, DOCX, HWP, HWPX, EML), edit PDFs (merge, split, rotate, compress, protect), resize and clean images, strip EXIF, cut out backgrounds, and generate QR codes. Runs entirely on your machine with no uploads. Each tool reopens what it wrote and reports page counts so broken output surfaces as a number, not a surprise.
soolaugust/0CompactMem Persistent memory MCP server with OS-style demand paging, kswapd-style eviction, and mlock pinning. Multi-agent shared SQLite store with BM25 + FTS5 retrieval, importance scoring, and capacity-aware reclaim. 5 tools: memorylookup, pinmemory, unpinmemory, memorystats, listpinned. uvx --from git+https://github.com/soolaugust/0CompactMem memory-os
