semantic_code_search

MCP tool from Code Graph MCP by sdsrss

Hybrid BM25 + vector search (RRF) for AST nodes. Supports compact mode

How to use it

Project documentation lists semantic_code_search for the Code Graph MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

ast_search

Search AST nodes by text and/or structural filters (type, return type, params)

find_references

Find all references to a symbol (callers, importers, inheritors, implementors, value/type references). Supports compact mode

get_ast_node

One symbol with signature, body and relations. includeimpact adds the blast radius, includesimilar embedding-similar nodes, includereferences callers/callees. Supports compact mode

get_call_graph

Trace upstream/downstream call chains for a function. Pass routepath='GET /api/x' to trace an HTTP route → handler → downstream instead

module_overview

Symbols in a directory or file, grouped by type and caller count. includedead lists unreferenced symbols under the path; includedeps adds the file dependency graph (single-file paths only)

project_map

Full project architecture: modules, dependencies, entry points, hot functions. includecentrality adds architectural chokepoints
