Search Optimization

This MCP server is specifically optimized for MCP development and provides intelligent search results:

Priority Categories

1. Core MCP Documentation (Highest Priority)
2. Claude Code MCP Integration
3. API Documentation
4. SDK and Development Tools
5. Tool Use and Examples
6. Prompt Engineering and Templates
7. Resources and Examples
8. Advanced Features
9. Security and Best Practices
10. Integration and Deployment

Relevance Scoring

• MCP keywords (+25 points): mcp, model context protocol, server, client, tool, api
• Development keywords (+15 points): sdk, python, typescript, javascript, example, template, guide, tutorial
• API keywords (+10 points): api, endpoint, request, response, authentication, key
• URL path priority: MCP docs get highest priority, followed by SDK and API documentation

Usage Examples

Once configured in your IDE, you can use the tools in your conversations:

• Search for MCP examples: "search_anthropic_docs" with query "MCP server examples"
• Get specific documentation: "fetch_doc" with a specific docs.claude.com URL
• Find API references: "search_anthropic_docs" with query "Claude API authentication"

Troubleshooting

Common Issues

1. Tools not appearing in IDE:

   • Ensure the package is installed globally: npm install -g @julianoczkowski/anthropic-docs-mcp-ts
   • Check your MCP configuration file syntax
   • Restart your IDE after configuration changes

2. Search returns no results:

   • Check your internet connection
   • Try different search terms
   • The server uses multiple search strategies with fallbacks

3. MCP connection issues:

   • Verify the anthropic-docs-mcp command works in your terminal
   • Check that the configuration file path is correct
   • Restart your IDE to pick up configuration changes
