OpenApps MCP probe

User-Agent: openapps-mcp-schema-probe/0.1 (+https://theopenapps.com/bot)

The probe reads what remote MCP servers offer: the tools, prompts and resources they list. It reads only the servers that apps in the ChatGPT, Claude, Cursor and Grok Bot app stores link to.

It sends only MCP discovery calls: initialize, tools/list, prompts/list and resources/list. It never calls a tool. It sends at most two requests a second across all servers.

It doesn't sign in. A server that asks for a sign-in is recorded as needing one.

Each request is signed with Web Bot Auth (RFC 9421) and names https://theopenapps.com in its Signature-Agent header. The public keys are at https://theopenapps.com/.well-known/http-message-signatures-directory.
