API Reference

Six HTTP endpoints. Bearer auth on all of them. Read the proxy and OAuth pages for the two you'll touch most.

Base URL

We expose endpoints as separate Cloud Functions, not under a single base path. Each endpoint uses its function name as the path segment.

Endpoints

• POST /proxyV2 — Execute a tool
• POST /initiateOAuth — Start end-user OAuth
• GET /handleOAuthCallback — Provider redirect target (you don't call this)
• POST /mcpServer — MCP SSE protocol
• POST /ingestWebhook — Receive upstream callbacks
• GET /openapiManifest — Public catalog manifest

Rate limits

429 responses include Retry-After in seconds.
