Graphistry MCP server - GPU-accelerated graph visualization for MCP clients
Graphistry MCP server exists for a simple reason — assistants are far more useful when they can act on Graphistry directly instead of describing what you should do. Graphistry MCP server - GPU-accelerated graph visualization for MCP clients.
GPU-accelerated graph visualization and analytics for Large Language Models using Graphistry and MCP.
This project integrates Graphistry's powerful GPU-accelerated graph visualization platform with the Model Control Protocol (MCP), enabling advanced graph analytics capabilities for AI assistants and LLMs. It allows LLMs to visualize and analyze complex network data through a standardized, LLM-friendly interface.
Installation goes through your MCP client rather than a global install: point it at @silkspace/graphistry-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Once Graphistry is connected, these are the calls the assistant has available:
visualize_graph — Visualize a graph or hypergraph using Graphistry's GPU-accelerated rendererget_graph_ids — List all stored graph IDs in the current sessionget_graph_info — Get metadata (node/edge counts, title, description) for a stored graphapply_layout — Apply a standard layout (force_directed, radial, circle, grid) to a graphdetect_patterns — Run network analysis (centrality, community detection, path finding, anomaly detection)encode_point_color — Set node color encoding by column (categorical or continuous)encode_point_size — Set node size encoding by column (categorical or continuous)encode_point_icon — Set node icon encoding by column (categorical, with icon mapping or binning)encode_point_badge — Set node badge encoding by column (categorical, with icon mapping or binning)apply_ring_categorical_layout — Arrange nodes in rings by a categorical column (e.g., group/type)apply_group_in_a_box_layout — Arrange nodes in group-in-a-box layout (requires igraph)apply_modularity_weighted_layout — Arrange nodes by modularity-weighted layout (requires igraph)You will need 2 environment variables: GRAPHISTRY_USERNAME, GRAPHISTRY_PASSWORD. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Graphistry's toolset — visualize_graph, get_graph_ids, get_graph_info and 11 more — is a fair guide to whether it matches your workflow. It is maintained by silkspace; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
| Tool | What it does |
|---|---|
| visualize_graph | Visualize a graph or hypergraph using Graphistry's GPU-accelerated renderer. |
| get_graph_ids | List all stored graph IDs in the current session. |
| get_graph_info | Get metadata (node/edge counts, title, description) for a stored graph. |
| apply_layout | Apply a standard layout (force_directed, radial, circle, grid) to a graph. |
| detect_patterns | Run network analysis (centrality, community detection, path finding, anomaly detection). |
| encode_point_color | Set node color encoding by column (categorical or continuous). |
| encode_point_size | Set node size encoding by column (categorical or continuous). |
| encode_point_icon | Set node icon encoding by column (categorical, with icon mapping or binning). |
| encode_point_badge | Set node badge encoding by column (categorical, with icon mapping or binning). |
| apply_ring_categorical_layout | Arrange nodes in rings by a categorical column (e.g., group/type). |
| apply_group_in_a_box_layout | Arrange nodes in group-in-a-box layout (requires igraph). |
| apply_modularity_weighted_layout | Arrange nodes by modularity-weighted layout (requires igraph). |
| apply_ring_continuous_layout | Arrange nodes in rings by a continuous column (e.g., score). |
| apply_time_ring_layout | Arrange nodes in rings by a datetime column (e.g., created_at). |
