What is FalkorDB MCP Server?

A Model Context Protocol (MCP) server for FalkorDB that enables AI assistants like Claude to query and interact with graph databases using natural language. It allows querying graph data with OpenCypher, creating and managing nodes and relationships, listing multiple graphs, and deleting graphs — all through conversational AI.

How to use FalkorDB MCP Server?

Install via npm (@falkordb/mcpserver) and configure environment variables for your FalkorDB instance (FALKORDB_HOST, FALKORDB_PORT, etc.) in a .env file or inline. Add the server to your Claude Desktop config under mcpServers, or run directly with npx using either stdio (default) or HTTP transport. For HTTP transport, set MCP_TRANSPORT=http and optionally MCP_PORT and MCP_API_KEY. A Docker Compose setup is also provided.

Key features of FalkorDB MCP Server

Query graph databases using OpenCypher (with read-only mode)
Parameterized queries to prevent injection risks
Dedicated read-only query tool (query_graph_readonly)
Create, manage, and delete nodes and relationships
List available graphs and explore schema (node labels, relationship types)
Schema discovery tools with sampling and connection topology
Works with stdio (default) or streamable HTTP transport
API key authentication for HTTP mode (optional)
Read-only mode for replica instances (set via FALKORDB_DEFAULT_READONLY)

Use cases of FalkorDB MCP Server

Ask an AI assistant to retrieve graph data using natural language queries
Let agents create and update nodes and relationships in a knowledge graph
Explore graph schemas and property distributions before writing queries
Run safe, read-only queries on replica or production databases
Integrate FalkorDB with Claude Desktop for conversational database management

常见问题

What are the prerequisites for using the server?

You need Node.js 18+, a running FalkorDB instance (local or remote), and optionally the Claude Desktop app for AI integration.

Does the server support read-only queries?

Yes. You can set `FALKORDB_DEFAULT_READONLY=true` for the whole server, or use the `readOnly` parameter per query. There is also a dedicated `query_graph_readonly` tool that always runs `GRAPH.RO_QUERY`.

How do I connect via HTTP transport?

Set `MCP_TRANSPORT=http` and optionally `MCP_PORT` (default 3000). Clients send a POST request with an `initialize` message; the server returns an `Mcp-Session-Id` header to include in subsequent requests. If `MCP_API_KEY` is set, clients must provide `Authorization: Bearer <key>`.

Can I use parameterized queries?

Yes. Both `query_graph` and `query_graph_readonly` accept an optional `params` object. Parameters are referenced as `$name` in the query text, avoiding injection risks. Note that `LIMIT` and `SKIP` clauses do not support parameters.

What schema discovery tools are available?

Three tools help agents orient themselves: `get_graph_schema` (returns node labels, relationship types, and connection topology), `get_node_schema`, and `get_relationship_schema` (both sample properties by frequency). All are read-only (`GRAPH.RO_QUERY`).
