Express REST API + MCP Server Framework
Express REST API + MCP Server Framework combining an Express.js REST API with an MCP server in a single Node.js application — providing boilerplate for building services that expose both HTTP REST endpoints and MCP tools from the same codebase, enabling developers to build dual-interface services for AI agents and traditional API consumers.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Framework — implement auth before production. HTTPS required. Separate REST/MCP auth policies.
⚡ Reliability
Best When
A TypeScript/Node.js developer needs to build a service that exposes both a REST API and MCP tools from the same application.
Avoid When
You only need an MCP server — use simpler MCP-only templates. Or if you only need REST — use standard Express boilerplate.
Use Cases
- • Building services with both REST API and MCP interfaces from full-stack developers
- • Migrating existing Express APIs to also support MCP from integration teams
- • Creating backend services that serve both traditional apps and AI agents
- • Bootstrapping new TypeScript projects with MCP and REST from teams
- • Building internal tools with REST for dashboards and MCP for agents
- • Learning how to combine Express and MCP in a single Node.js service
Not For
- • Teams only needing MCP (framework adds Express overhead without benefit)
- • Non-Node.js/TypeScript teams
- • Production-ready server (it's a boilerplate/framework starting point)
Interface
Authentication
Framework includes basic auth middleware. REST API and MCP auth implementation is developer responsibility.
Pricing
Free boilerplate. Self-hosted. No external service dependencies in core.
Agent Metadata
Known Gotchas
- ⚠ Boilerplate — you must implement your own tools and endpoints
- ⚠ Express and MCP transports use different server mechanisms — test both carefully
- ⚠ Community framework from individual contributor — limited support
- ⚠ Authentication must be added for production use — not production-ready out of the box
- ⚠ Node.js version compatibility should be checked
- ⚠ Running both REST and MCP from same process requires careful error handling
