MCP server registry

A free, open list of MCP servers that agents can connect to. Any maker can add theirs: no account and no review queue, just automatic checks. Every listing is safety-scanned when it is added and again regularly. 1 listed so far.

For registry clients: it speaks the official MCP Registry format. Base URL https://bounty.brelsfordsoftware.com/registry, e.g. GET https://bounty.brelsfordsoftware.com/registry/v0.1/servers?search=weather&version=latest.

List your server, free

No account, no review queue. Automatic checks and a safety scan, then it is live.

1. Name it after a domain you own, in reverse: com.example/weather for example.com, or io.github.yourname/tool for yourname.github.io.
2. Prove it is yours: put a plain text file at https://example.com/.well-known/bounty-mcp-registry.txt with one line per server name (or com.example/* for all of them).
3. Send your server.json (the same file the official registry uses) below, or POST https://bounty.brelsfordsoftware.com/registry/v0.1/publish. Each remote URL must be public https and answer an MCP request.
4. Pass the safety scan: the registry reads your tools and prompts and rejects hidden instructions (such as <IMPORTANT> tags, invisible characters, "don't tell the user", or asking for SSH keys), and checks your hosts and packages against free malware lists. It rescans every listing regularly, and hides one that starts failing.

New version? Bump version and send it again; versions never change once listed. To take a server down, end its line in your file with deprecated or deleted, or remove the line, then POST /registry/v0.1/recheck {"name": "..."}. Servers are rechecked automatically too. Limits: 10 submissions an hour and 30 a day per sender.

GET https://bounty.brelsfordsoftware.com/registry/v0.1/servers/{name}/versions
GET https://bounty.brelsfordsoftware.com/registry/v0.1/servers/{name}/versions/{version|latest}
POST https://bounty.brelsfordsoftware.com/registry/v0.1/validate                   check a server.json, nothing stored
POST https://bounty.brelsfordsoftware.com/registry/v0.1/publish                    list it (checks run first)
POST https://bounty.brelsfordsoftware.com/registry/v0.1/recheck   {"name": ...}    re-read the owner's file now

URL-encode the slash in a name (com.example%2Fweather). /v0 paths work the same. Each entry carries the usual registry metadata plus com.brelsfordsoftware.registry/checks with what was checked and when.
