Typical workflow

Search toolkits        GET  /proxy/tools/search?keywords=gmail
Start auth             POST /proxy/tools/auth           {"toolkit": "gmail"}
User completes OAuth   (browser redirect)
Verify connection      GET  /proxy/tools/connections
Inspect available tools GET  /proxy/tools/toolkit/gmail
Execute a tool         POST /proxy/tools/execute        {"tool": "GMAIL_SEND_EMAIL", ...}

For MCP connections, pass connection_id when discovering and executing tools. Read the returned inputParameters schema before building arguments; tool names and parameters are provider-specific. Execution returns a data, error, successful, and statusCode envelope. See Tools API for pagination, authorization intent, rate limits, and chat card behavior.
