graphpilot-oss/graphpilot

Overview

An open-source tool that indexes a repository once and exposes structural code information (symbols, callers, call edges) via the Model Context Protocol (MCP). Implemented in TypeScript, it acts as a semantic cache for coding agents to query code relationships without re-parsing.

Best for

Best for
Developers prototyping or building MCP-based coding agents that need structural code context.

Use cases

• Equip coding agents with a lightweight repo-wide symbol index
• Query call edges to trace function usage across a codebase
• Retrieve caller and callee lists for refactoring or dependency analysis

How to use

Install

npm install -g @graphpilot-oss/graphpilot

Tested with

Claude Code, Cursor, Cline, Windsurf, Continue, VS Code, ChatGPT

Example client config

{\n  "mcpServers": {\n    "graphpilot": {\n      "command": "graphpilot",\n      "args": ["mcp"]\n    }\n  }\n}

Use cases

• Equip coding agents with a lightweight repo-wide symbol index
• Query call edges to trace function usage across a codebase
• Retrieve caller and callee lists for refactoring or dependency analysis

Pros

• Single-index design reduces repeated parsing overhead for agents
• Uses standard MCP, making it integrable with MCP-compatible agents
• Minimal dependency footprint (pure TypeScript)

Cons

• Very early stage with only 10 GitHub stars and limited community validation
• No evidence of support for languages beyond the tool’s own implementation language (TypeScript)
• Requires manual indexing step before queries are possible
