• Automatic Updates: Daily scheduled updates to keep documentation current
• Full-text Search: Advanced search capabilities across all documentation sources
• MCP Integration: Native integration with GitHub Copilot and other MCP-compatible tools
• SQLite Storage: Efficient local caching with SQLite database
• Markdown Support: Clean markdown formatting for better readability

Documentation Sources

• Rust: Standard library documentation and The Rust Programming Language book
• Tauri: Complete Tauri framework documentation
• React: Official React documentation and guides
• TypeScript: TypeScript handbook and language reference
• Python: Official Python documentation including tutorials and library reference
• Tailwind CSS: Complete Tailwind CSS V4+ utility-first framework documentation
• shadcn/ui: Component library documentation and examples

Installation

Prerequisites

• Rust 1.70 or later
• SQLite 3

Building from Source

./target/release/update-docs

# Update with custom database path
./target/release/update-docs --database /path/to/docs.db

GitHub Copilot Integration

To use this MCP server with GitHub Copilot, add it to your MCP configuration:

{
  "mcpServers": {
    "docs-server": {
      "command": "/path/to/target/release/docs-mcp-server",
      "args": ["--database", "/path/to/docs.db"]
    }
  }
}

Available Tools

search_documentation

Search across all documentation sources for relevant information.

Parameters:

• query (required): Search query for documentation content
• source (optional): Limit search to specific documentation source (rust, tauri, react, typescript, python, tailwind, shadcn)
• limit (optional): Maximum number of results to return (default: 10)

Example:

{
  "name": "search_documentation",
  "arguments": {
    "query": "async functions",
    "source": "rust",
    "limit": 5
  }
}

get_documentation_page

Get a specific documentation page by path.

Parameters:

• source_id (required): Documentation source ID (e.g., 'rust-std', 'react-docs')
• path (required): Path to the specific documentation page

list_documentation_sources

List all available documentation sources and their status.

Available Resources

The server provides the following resources that can be accessed directly:

• docs://rust/std - Rust Standard Library Documentation
• docs://rust/book - The Rust Programming Language Book
• docs://tauri - Tauri Documentation
• docs://react - React Documentation
• docs://typescript - TypeScript Documentation
• docs://python - Python Documentation
• docs://tailwind - Tailwind CSS Documentation
• docs://shadcn - shadcn/ui Documentation

Configuration

Environment Variables

• RUST_LOG: Set logging level (default: info)

Command Line Options

• --database <PATH>: Path to SQLite database file (default: docs.db)
• --update-now: Force update documentation before starting server

Development

Running in Development Mode

# Run with cargo
cargo run

# Run with auto-reload
cargo watch -x run

Running Tests

cargo test

Code Formatting

cargo fmt

Linting

cargo clippy

Database Schema

The server uses SQLite with the following main tables:

• documentation_sources: Stores information about documentation sources
• document_pages: Stores individual documentation pages
• document_pages_fts: Full-text search index for efficient searching

Scheduling

The server automatically schedules daily updates at 2 AM UTC. You can also trigger manual updates using the update-docs binary or by starting the server with the --update-now flag.

Error Handling

The server includes comprehensive error handling and logging. All errors are logged with appropriate context, and the server will continue running even if individual documentation updates fail.

Performance

• Caching: All documentation is cached locally in SQLite for fast access
• Incremental Updates: Only updates changed content to minimize bandwidth
• Full-text Search: Uses SQLite FTS5 for efficient text searching
• Connection Pooling: Efficient database connection management

Troubleshooting

Common Issues

1. Database Lock Errors: Ensure only one instance of the server is running
2. Network Timeouts: Check internet connection and firewall settings
3. Permission Errors: Ensure write access to the database directory

Logging

Enable detailed logging by setting the RUST_LOG environment variable:

RUST_LOG=debug ./target/release/docs-mcp-server
