# 🔍⁉️ Neo4j MCP Server mcp-name: io.github.neo4j-contrib/mcp-neo4j-cypher ## 🌟 Overview A Model Context Protocol (MCP) server implementation that provides database interaction and allows graph exploration capabilities through Neo4j. This server enables running Cypher graph queries, analyzing complex domain data, and automatically generating business insights that can be enhanced further with an application's analysis tools. This MCP server facilitates Text2Cypher workflows like the one detailed below. * Blue steps are handled by the agent * Purple by the Cypher or another MCP server * Green by the user A user question is input to the process and the output is an answer generated by the agent.  ## 🧩 Components ### 🛠️ Tools The server offers these core tools: #### 📊 Query Tools - `read_neo4j_cypher` - Execute Cypher read queries to read data from the database - Input: - `query` (string): The Cypher query to execute - `params` (dictionary, optional): Parameters to pass to the Cypher query - Returns: Query results as JSON serialized array of objects - **Timeout**: Read queries are subject to a configurable timeout (default: 30 seconds) to prevent long-running queries from disrupting conversational flow - `write_neo4j_cypher` - Execute updating Cypher queries - Input: - `query` (string): The Cypher update query - `params` (dictionary, optional): Parameters to pass to the Cypher query - Returns: A JSON serialized result summary counter with `{ nodes_updated: number, relationships_created: number, ... }` - **Availability**: May be disabled by supplying --read-only as cli flag or `NEO4J_READ_ONLY=true` environment variable #### 🕸️ Schema Tools - `get_neo4j_schema` - Get a list of all nodes types in the graph database, their attributes with name, type and relationships to other node types - Input: - `sample_param` (integer, optional): Number of node…
