Neo4j MCP Canary

Neo4j MCP Canary is a fast-moving, experimental release of the Neo4j MCP server for customers who want to explore emerging capabilities before they are considered for the official server. Its 18 documented tools cover cypher, index, vector, constraint. It runs locally over stdio via the published package.

People who work with cypher, index and vector and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

01 · Install Neo4j MCP Canary

before you install - you'll need

Set CGO_ENABLED, NEO4J_URI, NEO4J_TRANSPORT_MODE, NEO4J_MCP_HTTP_TLS_ENABLED, NEO4J_MCP_HTTP_TLS_CERT_FILE, NEO4J_MCP_HTTP_TLS_KEY_FILE, NEO4J_CONFIG_FILE, NEO4J_OUTPUT_FORMAT, NEO4J_MCP_ENABLED_TOOLS, NEO4J_MCP_ENABLED_TOOL_CATEGORIES before connecting.

Claude Code

claude mcp add neo4j-labs-neo4j-mcp-canary -- uvx neo4j-mcp-canary

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "neo4j-labs-neo4j-mcp-canary": {
      "command": "uvx",
      "args": [
        "neo4j-mcp-canary"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package neo4j-mcp-canary - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.neo4j-labs is GitHub-verified and matches the repo owner
