MCP Docs Server

You can run an MCP Docs Server to search and fetch MCP protocol documentation quickly. It uses BM25-based search with markdown-aware indexing and runs as a local stdio server, making it easy to integrate into your MCP clients for fast, contextual documentation access.

How to use

You connect your MCP client to the MCP Docs Server to search for documentation and fetch full documents on demand. Use the search tool to get ranked results for a topic, then fetch a selected document by its URL to display full content in your workflow. The server is designed to start quickly, indexing document titles at startup while retrieving content as you request it. This makes it ideal for quick lookups during development, testing, or troubleshooting MCP protocol usage.

How to install

Prerequisites you need before installing include Node.js and npm. Ensure you have a working Node/npm environment before proceeding.

# Quick Start (Recommended) 1
# Add to your MCP client configuration

{ "mcpServers": { "mcp-docs-server": { "command": "npx", "args": ["-y", "@praveenc/mcp-docs-server"] } } }

That's it! The server will be downloaded and run automatically.

If you prefer a global installation so you can run the server from anywhere, use the following command to install the package globally:

npm install -g @praveenc/mcp-docs-server

Then configure your MCP client using the local binary installed on your system, for example:

{ "mcpServers": { "mcp-docs-server": { "command": "mcp-docs-server" } } }

## Additional configuration and notes

The server supports two practical runtime modes. You can either invoke it via npx for a temporary, on-demand run or rely on a globally installed binary for a persistent setup. In both cases, you treat the MCP Docs Server as a local endpoint that provides search and fetch capabilities for MCP protocol documentation.

No extra environment variables are shown for running these configurations in the provided usage examples. If you introduce environment-specific options later, you can extend the server configuration accordingly.

## Security and operation considerations

Operate the server on trusted networks or localhost to avoid exposing internal documentation endpoints to untrusted users. When running in a shared environment, limit access to the local machine or the intended MCP client, and consider implementing access controls if you expose the server over a network.

## Testing and validation

After starting the server through either method, validate its operation by performing a few searches from your MCP client and confirming that fetching a document returns the expected content. This helps ensure your client integrations are wired correctly and that the server can access the latest documentation as needed.

## Troubleshooting

If you encounter startup failures, verify you have a recent Node.js and npm setup, and confirm network access for dependency resolution when using the npx approach. For local binary usage, ensure the binary name is accessible from your system PATH and that you have permission to execute it.
