Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"iflow-mcp-nahisaho-codegraph-mcp-server","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# CodeGraphMCPServer **A lightweight, high-performance source code analysis MCP server with zero configuration** [](https://www.python.org/downloads/) [](https://opensource.org/licenses/MIT) [](https://modelcontextprotocol.io/) []() []() [](https://github.com/nahisaho/CodeGraphMCPServer/actions/workflows/ci.yml) [🇯🇵 日本語版 README](README.ja.md) ## Overview CodeGraphMCPServer is an MCP server that understands codebase structure and provides GraphRAG (Graph Retrieval-Augmented Generation) capabilities. With a self-contained architecture requiring no external database, it enables structural understanding and efficient code completion from MCP-compatible AI tools (GitHub Copilot, Claude Desktop, Cursor, etc.). ### 🧠 GraphRAG Features - **Community Detection**: Automatic code module clustering using Louvain algorithm - **LLM Integration**: Multi-provider design supporting OpenAI/Anthropic/Local LLMs - **Global Search**: Codebase-wide understanding using community summaries - **Local Search**: Context retrieval from entity neighborhoods ### ✨ Features | Feature | Description | |---------|-------------| | 🚀 **Zero Configuration** | No external DB required, `pip install && serve` to start immediately | | 🌳 **AST Analysis** | Fast and accurate code analysis with Tree-sitter | | 🔗 **Graph Construction** | Builds graphs of relationships between code entities | | 🔍 **14 MCP Tools** | Dependency analysis, call tracing, code search | | 📚 **4 MCP Resources** | Entities, files, communities, statistics | | 💬 **6 MCP Prompts** | Code review, feature implemen…
