Features

  • Schema Introspection
    Retrieve full graph schema (vertex & edge types).
  • Query Execution
    Run installed GSQL queries or raw GSQL strings with parameters.
  • Vertex & Edge Upsert
    Create or update vertices and edges programmatically.
  • Resource URIs
    Access graph objects through tgraph://vertex/... and tgraph://query/... URIs.
  • UDF & Algorithm Listing
    Fetch installed user-defined functions and GDS algorithm catalogs.

Installation

  1. Clone the repo
    git clone https://github.com/Muzain187/TG_MCP.git cd TG_MCP
  2. Create & activate a virtual environment
    python3 -m venv venv source venv/bin/activate
  3. Install dependencies
    pip install .

    Requires mcp[cli]>=1.6.0 and pyTigerGraph>=1.8.6.

Configuration

Set the following environment variables before running:

export TG_HOST=https://<your-tigergraph-host> export TG_GRAPH=<your-graph-name> export TG_SECRET=<your-api-secret>

These are read by config.py.

Connecting to Claude

This MCP server can be installed into the Claude Desktop client so that Claude can invoke your TigerGraph tools directly:

uv run mcp install main.py

After running the above, restart Claude Desktop and you’ll see your MCP tools available via the hammer 🛠 icon.
