Master MCP Server

Master MCP Server

Master MCP Server aggregates multiple MCP servers behind a single, secure endpoint. It provides configuration-driven module loading, unified capability discovery, request routing with resilience, and first-class OAuth flows for multi-backend authentication.

Highlights

• Aggregates multiple MCP servers with tool/resource discovery and namespacing
• OAuth support: master token pass-through, delegated provider flows, proxy refresh
• Config-driven setup with JSON/YAML, schema validation, and secret resolution
• Resilient routing: load-balancing, retries with backoff/jitter, circuit-breakers
• Cross-platform: Node.js server and Cloudflare Workers runtime
• Production-ready deployment: Docker, Cloudflare Workers, Koyeb
• Testing strategy and CI-ready structure

Quick Start (Node.js)

1. Install dependencies (requires network):

2. Configure environment (copy and edit):

3. Run in dev mode:

4. Health and Metrics:

• GET /health → { ok: true }
• GET /metrics → basic system metrics

5. MCP endpoints (HTTP gateway):

• POST /mcp/tools/list
• POST /mcp/tools/call with { name, arguments }
• POST /mcp/resources/list
• POST /mcp/resources/read with { uri }

See docs/ for full guides and end-to-end examples.
