NetworkX Graph MCP Server

Create a new state/decision graph (directed, cycles allowed).

Delete a state graph.

List all available state graph files on disk (memory resets each session, so this scans for YAML/JSON files in graphs directories). Returns file paths that can be imported.

Get graph metadata and stats.

Add a node (action/decision/verification/loop/success/failure).

Update node properties (label, phase, tool, properties).

Remove a node.

Get node details.

List all nodes.

Add an edge with order and optional condition.

Remove an edge.

Get edges (optionally filter by node).

Set execution order for an edge.

Set condition label for an edge.

Get incoming/outgoing edges for a node.

Add multiple nodes at once (parents before children).

Add multiple edges at once (with order/condition).

Export graph to YAML or JSON file.

Import graph from YAML or JSON file.

Render graph to PNG file (saves to disk, not base64).

Validate graph structure (cycles allowed, warnings only).

Get statistics: node counts by type, edges, phases, decision points, loops.

Find shortest path between two nodes.

Get nodes in execution order from a start node, following edges by order attribute. Stops at first decision node by default. Returns sequence of nodes with their details.
