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":"mcp-neo4j-graphrag","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# Neo4j GraphRAG MCP Server [](https://pypi.org/project/mcp-neo4j-graphrag/) [](https://www.python.org/downloads/) [](https://opensource.org/licenses/MIT) An MCP server that extends Neo4j with **vector search**, **fulltext search**, **search-augmented Cypher queries**, **write operations**, and **multimodal image retrieval** for GraphRAG applications. > **Inspired by** the [Neo4j Labs `mcp-neo4j-cypher`](https://github.com/neo4j-contrib/mcp-neo4j/tree/main/servers/mcp-neo4j-cypher) server. This server adds vector search, fulltext search, and the innovative `search_cypher_query` tool for combining search with graph traversal. ## Overview This server enables LLMs to: - 🔍 Search Neo4j vector indexes using semantic similarity - 📝 Search fulltext indexes with Lucene syntax - ⚡ Combine search with Cypher queries via `search_cypher_query` - 🕸️ Execute read-only Cypher queries - ✏️ Execute write Cypher queries (CREATE, MERGE, SET, DELETE) - 🖼️ Retrieve images stored in Neo4j nodes (multimodal — returns the image directly to the LLM) Built on [LiteLLM](https://docs.litellm.ai/) for multi-provider embedding support (OpenAI, Azure, Bedrock, Cohere, etc.). > **Related:** For the official Neo4j MCP Server, see [neo4j/mcp](https://github.com/neo4j/mcp).
