The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y [email protected]`. - Your MCP client knows it as `openapi-sync` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__openapi-sync__<tool>`. - No credentials. ## Tools 10 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.
