How to Set Up and Use Model Context Protocol
The modelcontextprotocol repository is the official home of the Model Context Protocol specification and schema, maintained by Anthropic. It contains the canonical TypeScript-first protocol schema (also available as JSON Schema), the formal specification documents, and the source for the official documentation site at modelcontextprotocol.io. Developers reference this repository to understand exactly what the protocol supports, to validate their MCP server or client implementations against the official schema, and to track changes as the specification evolves — currently at version 2025-11-25.
Prerequisites
- Node.js 18 or newer (for working with the TypeScript schema)
- Git to clone the repository
- Familiarity with TypeScript for reading the schema source
- An MCP client or server you want to validate against the spec
Clone the specification repository
Clone the official MCP specification repository to access the schema files and documentation source locally.
git clone https://github.com/modelcontextprotocol/modelcontextprotocol.git
cd modelcontextprotocolExplore the schema directory
Navigate to the schema directory to find the TypeScript and JSON Schema definitions. The current version is 2025-11-25.
ls schema/
# You will see directories for each spec version, e.g.:
# 2025-11-25/ 2025-06-18/ 2025-03-26/ 2024-11-05/Install schema dependencies
Install the Node.js dependencies if you want to work with the TypeScript schema, compile it, or run the documentation build.
npm installUse the JSON Schema for validation
Reference the JSON Schema file to validate MCP messages in your implementation. The schema is available for each protocol version.
# Validate an MCP message using ajv or similar:
npx ajv validate -s schema/2025-11-25/schema.json -d your-mcp-message.jsonRead the official documentation
For comprehensive guides on implementing clients and servers, visit the official documentation site built from this repository.

JSON Schema reference in package.json
Reference the official MCP JSON Schema directly in your project for validation or IDE autocompletion.

Questions and tasks you can accomplish by referencing the MCP specification.
- "What fields are required in an MCP tool definition according to the 2025-11-25 schema?"
- "Show me the JSON Schema for an MCP CallToolResult response"
- "What changed between MCP spec version 2025-03-26 and 2025-11-25?"
- "Validate this MCP server response against the official schema"
- "Explain the difference between MCP tools, resources, and prompts as defined in the spec"Troubleshooting Model Context Protocol
Schema validation errors on messages that seem correct
Ensure you are validating against the correct schema version. MCP clients and servers negotiate the protocol version during the initialization handshake — use the schema file that matches the negotiated version, not necessarily the latest.
TypeScript schema compilation fails with type errors
Run 'npm install' in the repository root first to install all type dependencies. If errors persist, check that your Node.js version is 18 or newer with 'node --version'. The schema uses modern TypeScript features that require up-to-date tooling.
Documentation site build fails locally
The docs use Mintlify. Install the Mintlify CLI with 'npm i -g mintlify' and run 'mintlify dev' in the docs directory. Check the repository's CONTRIBUTING.md for the exact commands and Node.js version requirements.
