What to compare
- publisher and server identity
- protocol and server version
- transport and authentication
- requested scopes and effects
- source licence and maintenance
Read the sources
Official MCP Registry ↗
Server metadata and discovery documentation for MCP-compatible tools and services.
Use the registry's documented read API and publisher references; discovery does not authorize a server connection. Registry inclusion does not certify safety, uptime or licence compatibility. Review each server and requested scope.
GitHub Releases API ↗
Release metadata for a chosen repository, including tags and published assets.
Use the documented API with its authentication, pagination and request limits. Pin the repository and release identity. A release asset remains subject to its own licence and integrity checks.
When to look again
Before enabling a server, after a protocol or authentication change, and during periodic access reviews.
