pdbe_graph_node_relationships
Verifies selected node labels and returns the incoming, outgoing, and self-loop relationship patterns defined for each label. This uses the public graph schema and does not require local Neo4j credentials.
How to use it
Project documentation lists pdbe_graph_node_relationships for the PDBe MCP Servers MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
