List this server
For catalogs, marketplaces and clients that list MCP servers. Listing GunSpec is welcome, and this page says what a health check will see, how to get a key for one, and how we prove that key can do nothing else.
What a check sees without a key
Every request needs a key in the X-API-Key header, tools/list included, so a health check or tool discovery run without one is answered 401 and your listing will show the server as unavailable.
curl -sS -X POST https://mcp.gunspec.io \ -H 'Content-Type: application/json' \ -H 'Accept: application/json, text/event-stream' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' {"error":"unauthorized","message":"A GunSpec API key is required."}If your listing only needs the tool names, descriptions and argument schemas, they are published keylessly, exactly as tools/list sends them: tools.json
A key for your checks
Write to us and we will issue one. It is not an ordinary customer key:
- Restricted to this server. Sent to the API directly it is refused, so it is worth nothing outside the health check you use it for.
- On the Explorer plan with its ordinary rate limit and daily MCP allowance, which a health check stays well inside.
- Revocable and named for you, so it can be replaced without affecting anyone else.
- It reads the same public catalog any Explorer key reads. No customer data is reachable with it.
How we prove that, nightly
A restriction nothing exercises is a promise. Our nightly health run holds a key of exactly this kind against all three questions, and publishes the answers here whether they pass or fail.

Everything for your listing
The values a catalog asks for, each one copied with a click. They come from the same configuration the server and the registry entry are built from, so a listing made here cannot quote an address we have stopped using.

Badges
Show the server's status on your listing or in a README.
Server status
Whether the server is answering, probed from outside every five minutes: online, degraded, or offline.
Documented behaviour
Whether what the server answers still matches this documentation. Amber means some checks fail; the server is still answering.
Tool quality and endpoint healthby Glama
Glama's own score for this connector, from their checks rather than ours.
The first badge is uptime, probed from outside by our status app. The second is the nightly health run: green when every check passed, amber when some failed and the server is still answering, red when none passed, grey before a run exists. Both are drawn by us and cached for five minutes.

Nothing here is "unknown": every field a directory asks about is either answered above or marked as not applying to this endpoint. If your form has a field this table does not, write to support and we will answer it and add it here.
The registry entry
This server is published in the official MCP Registry as io.gunspec/mcp, which several catalogs mirror. Use it as the source for your listing: it carries the URL, the transport and the header, and each release lists itself after it deploys.
