Portable descriptions for MCP servers
The {mcpdesc} project is an independent open source initiative promoting an open, portable, machine-readable description format for MCP servers.
Benefits
Accurate Documentation
Generate reliable documentation for tools, resources, prompts, transports, and security from a single source of truth.
Quality Assurance & Compliance
Lint, validate, and compare MCP Description documents to catch gaps in completeness and consistency before they reach production.
CI/CD Automation
Store, version, review, and publish MCP Description documents alongside engineering pipelines.
Conformance Checking
Verify that what a server claims to expose matches what it actually implements.
Design-First Workflow
Design a server in an MCP Description document, refine the design with a mock service, then generate code from the description.
Interoperability
One format that ecosystem tools can read, write, validate, render, diff, and generate code from.
