Before you install Code Index MCP

AgenticMart scanned Code Index MCP on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

  1. Pin the version you reviewed instead of always installing the latest release.
  2. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
  • Maintained by johnhuang316 on GitHub, 1,007 stars and 119 forks. Popularity is not proof of safety.
  • Last code change: Jul 27, 2026.

Tools Code Index MCP exposes (14)

Listed by the server itself during our scan of commit d395cbf.

  • set_project_path

    Set the base project path for indexing.

  • search_code_advanced

    Search for code pattern with pagination. Auto-selects best search tool (ugrep/ripgrep/ag/grep). Supports glob file_pattern (e.g., "*.py"), explicit regex mode, and fuzzy matching (ugrep only). Regex matching requires passing regex=True and may require an external search tool.

  • find_files

    Find files matching glob pattern using in-memory index. Supports path patterns (*.py, test_*.js) and filename-only matching (README.md).

  • get_file_summary

    Get a summary of a specific file, including: - Line count - Function/class definitions (for supported languages) - Import statements - Basic complexity metrics

  • get_symbol_body

    Get the source code body of a specific symbol (function, method, or class). This tool retrieves only the code for the specified symbol, enabling efficient context usage by avoiding loading entire files. Args: file_path: Path to the file containing the symbol symbol

  • refresh_index

    Manually rebuild the project file index. Use after git operations or when index seems stale.

  • build_deep_index

    Build the deep index (full symbol extraction) for the current project. This performs a complete re-index and loads it into memory. Uses parallel processing by default. For large codebases (3000+ files), tuning max_workers can significantly improve build times. Args: ma

  • get_settings_info

    Get information about the project settings.

  • create_temp_directory

    Create the temporary directory used for storing index data.

  • check_temp_directory

    Check the temporary directory used for storing index data.

  • clear_settings

    Clear all settings and cached data.

  • refresh_search_tools

    Manually re-detect the available command-line search tools on the system. This is useful if you have installed a new tool (like ripgrep) after starting the server.

  • get_file_watcher_status

    Get file watcher service status and statistics.

  • configure_file_watcher

    Configure file watcher service settings. Args: enabled: Whether to enable file watcher debounce_seconds: Debounce time in seconds before triggering rebuild additional_exclude_patterns: Additional directory/file patterns to exclude observer_type: Observer backend
