GraphOS MCP Server

This hosted GraphOS MCP server exposes two kinds of tools: - Public documentation tools (ApolloDocsSearch, ApolloDocsRead, ApolloConnectorsSpec) that require no authentication. Search the documentation first, then read full pages via the returned slugs. - Graph Health Check tools (for example GetVariantDetails, GetLatestLaunch, GetLintResults) that inspect a specific graph and REQUIRE authentication: the server forwards your `x-api-key` request header to the Apollo Platform API. Use a GraphOS graph/service key for the graph you are inspecting; a personal/user key is not used, and there is no APOLLO_KEY for clients of this hosted server. If a health-check tool fails auth (for example `API_KEY_MISSING_OR_INVALID`) or returns null identity or empty data, the server was likely added without an `x-api-key` header. Re-add it with: `claude mcp add --transport http <name> <url> --header "x-api-key: <your key>"`. The documentation tools work with or without a key.
