# TG_MCP
![Integration](https://github.com/user-attachments/assets/cea6c4a3-1293-4bac-8c20-d1ecd7f0e866)


A lightweight Python interface that exposes TigerGraph operations (queries, schema, vertices, edges, UDFs) as structured tools and URI-based resources for MCP agents.

## 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**  
   ```bash
   git clone https://github.com/Muzain187/TG_MCP.git
   cd TG_MCP
   ```

2. **Create & activate a virtual environment**  
   ```bash
   python3 -m venv venv
   source venv/bin/activate
   ```

3. **Install dependencies**  
   ```bash
   pip install .
   ```
   > Requires `mcp[cli]>=1.6.0` and `pyTigerGraph>=1.8.6`.

## Configuration

Set the following environment variables before running:

```bash
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:

```bash
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.
