Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
osm-mcp-pucaCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Integrate the server with any MCP‑compatible client. For Docker, add an OpenAI API Key to .env and run docker compose up -d, then visit http://your.ip.address:3301. For Claude, edit claude_desktop_config.json to include the server’s SSE endpoint. For Python, see the example client.py using Pydantic AI.
Claude Desktop / Cursor

Usage
This MCP server can be integrated with your client that supports MCP.

Docker
The docker-compose.yaml file included will run both the púca UI and MCP server so that you can enter queries into the UI.
To do so you will need to add your own OpenAI API Key in the .env file then start the containers with:
docker compose up -d
Check the logs for any issues and visit the web interface at http://your.ip.address:3301
Pydantic AI
See the example file client.py for how to use this MCP server with Python's pydantic_ai
Claude
Anthropic's Claude supports adding MCP servers if you edit the file:
vi ~/Library/Application\ Support/Claude/claude_desktop_config.json
adding the following but amending the URL:
{
"mcpServers": {
"puca": {
"command": "npx",
"args": [
"mcp-remote",
"http://192.168.1.40:3300/sse"
]
}
}
}
