MCP servers that ship as code — a repository or a package you install and run locally (usually over stdio). They have no hosted endpoint, so we cannot probe or grade them: instead each one shows its repository, install command, license, stars and when it was last updated.
Collected from GitHub repositories and npm, PyPI, Cargo, Go, Maven, NuGet and RubyGems packages tagged as MCP servers, the official MCP Registry, Docker's MCP catalog, ModelScope, Baidu MCP World, Cline and other public directories; one entry per repository. A server that also offers a hosted endpoint is listed under Remote instead. These entries are not counted in our reachability, verification or readiness statistics.

Deterministic preflight for the intent you hand a coding agent. check_intent_readiness scores a spec against six calibrated gates - title, objective, outcomes, constraints, edge cases, verification - and names the exact blockers.

Add a Pathmode API key to sync intent and evidence across a team and check pull requests against the outcomes you agreed to.
