Clangd MCP Server

What it does

This server connects an AI assistant to the clangd language server, providing deep C and C++ code intelligence. It allows AI agents to navigate complex codebases, understand type hierarchies, and detect compiler errors in real-time.

Tools

• find_definition: Jump-to-definition for a symbol at a given position.
• find_references: Find all references to a symbol across the codebase.
• get_hover: Retrieve type information and documentation for a symbol.
• get_diagnostics: Get compiler errors and warnings for a specific file.
• get_document_symbols: Extract a full symbol outline for a file.
• workspace_symbol_search: Search for symbols by name across the entire project.
• find_implementations: Find all implementations of a virtual method or interface.
• get_call_hierarchy: Analyze incoming callers or outgoing callees for a function.
