Comparison
API Atlas vs MCP.Directory
MCP.Directory — One of the larger dedicated MCP directories, with a focus on browsing and one-click installation.
Where MCP.Directory is the better choice
- Deep, MCP-only focus with a browsing experience built specifically for servers.
- Good at surfacing installation paths for popular clients.
Where it has limits
- MCP only — if you also need conventional REST APIs, it is a second site to visit.
- Editorial "best of" coverage is thinner than the raw listing.

Which should you use?
- Choose MCP.Directory if its strengths above match your task — deep, MCP-only focus with a browsing experience built specifically for servers.
- Choose API Atlas if you need to search APIs and MCP servers in one place, filter by what a record actually requires (authentication, CORS, free tier), and land on the provider’s own documentation — across 53 topics and 10,161 records.
- Use both. Most of these tools are complementary; the catalogue is public and links out to everything it lists. There is no reason to pick one exclusively.
