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 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`.

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
