The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y [email protected]`. - Your MCP client knows it as `repo-cartographer` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__repo-cartographer__<tool>`. - No credentials. ## Tools 5 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

build_import_graphExtract intra-repo import/require relationships for JavaScript/TypeScript and Python. Nodes are files (auto-collapsed to module/directory level for large repos); edges are directed import relationships. Returns JSON. Use this when you need the raw dependency edges — who imports whom — e.g. to reason about coupling, cycles, layering, or the blast radius of a change. Do NOT use it just to draw a picture: generate_diagram returns a ready-to-render draft, and map_repo does the whole flow in one call.Extract intra-repo import/require relationships for JavaScript/TypeScript and Python.
