Docs.rs and MCP Integration

This section explores how docs.rs, the documentation hosting service for Rust crates, can leverage the Model Context Protocol (MCP) to enhance documentation generation and access.

MCP Server for Documentation

class DocsRsServer extends MCPServer {
  capabilities = {
    tools: {
      'search-docs': this.handleDocSearch,
      'generate-docs': this.handleDocGeneration,
      'analyze-examples': this.handleExampleAnalysis
    },
    resources: {
      'crate-metadata': this.handleCrateMetadata,
      'doc-content': this.handleDocContent,
      'usage-examples': this.handleExamples
    }
  }
}

Key Features

  1. Documentation Enhancement

    • AI-powered documentation suggestions
    • Code example generation
    • Cross-reference validation
  2. Search and Discovery

    • Semantic documentation search
    • Context-aware API lookups
    • Related function discovery
  3. Integration Features

    • IDE documentation plugins
    • CLI documentation tools
    • Documentation testing tools

Common Use Cases

  1. Documentation Generation

    • Automated API documentation
    • Example code generation
    • Documentation completeness checks
  2. Documentation Search

    • Natural language queries
    • Code snippet search
    • API usage examples
  3. Documentation Maintenance

    • Broken link detection
    • Version compatibility checks
    • Documentation coverage analysis

Best Practices

  • Implement proper error handling
  • Cache documentation resources
  • Support offline documentation access
  • Maintain documentation versioning
