Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Domain Health Check SPF, DKIM, and DMARC records for example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Model Context Protocol servers, each built to be the best available in its niche, and each proven by measurement against the best existing server before it ships.
Every server here:
installs with one command (npx), one click (Claude Desktop bundle, signed), or Docker;
keeps its tool list small and byte-stable, so it costs few tokens and caches well;
returns compact JSON with an output schema, and says when a list was cut;
reaches only the hosts it declares, over HTTPS, with deadlines, size caps and bounded retries;
is tested on recorded upstream responses, and checked weekly against the live upstream;
is published from CI with npm provenance and a Sigstore-signed bundle.

docs/SPEC.md describes the production line: scout, build, gate, benchmark, ship. The gate
(gate/) is the same for every server and runs in CI on Node 20, 22 and 24.
npm ci

npm run new -- <name> --title "..." --description "..." --host api.example.org --instructions "..."
npm run sync # after changing kit/, a tool, or adding a server

node scripts/publish-repos.mjs [name] # push committed servers to their own repositoriesEach server lives in its own repository (linked above); this repository is where they are built and
checked. catalog.json lists every server and its tools.
