      "args": ["--from", "cased-kit", "kit-dev-mcp"],
      "env": {
        "OPENAI_API_KEY": "sk-...",  // Optional for deep research
        "OPENAI_BASE_URL": "https://your-proxy.com/v1"  // Optional for custom OpenAI endpoints
      }
    }
  }
}

For Claude Desktop

      "args": ["-m", "kit.mcp.dev"],
      "env": {
        "OPENAI_API_KEY": "sk-...",  // Optional for deep research
        "OPENAI_BASE_URL": "https://your-proxy.com/v1",  // Optional for custom OpenAI endpoints
        "CHROMA_PACKAGE_SEARCH_API_KEY": "..."  // Optional for package source search

Available Tools

The server provides many tools including:

open_repository - Open local or remote Git repositories
grep_code - Fast literal string search (120s default timeout, configurable via KIT_GREP_TIMEOUT)
grep_ast - Search code using AST patterns (semantic search)
get_file_tree - Repository file structure with pagination support (limit/offset params)
extract_symbols - Extract functions, classes, and symbols (excludes code by default for ~90% token savings; use include_code=true to get full source)
get_symbol_code - Get source code of a specific symbol (lazy loading for context efficiency)
find_symbol_usages - Find where symbols are used
warm_cache - Pre-warm caches for faster operations on large codebases (100K+ files)
review_diff - AI-powered diff reviews
deep_research_package - Comprehensive package documentation
package_search_grep - Search package source code with regex patterns
package_search_hybrid - Semantic search in package source code
