# ParticlePhysics MCP Server
[](https://lobehub.com/mcp/uzerone-particlephysics-mcp-server)
A Model Context Protocol (MCP) server that provides access to the particle data. This server enables Claude Desktop and other MCP clients to search and retrieve particle physics data in real-time.
## Status and Progress
- 🛠️ Work on displaying particle values with associated errors is ongoing.
## Configuration
```json
{
"mcpServers": {
"particlephysics": {
"command": "uvx",
"args": ["--from", ".", "python", "-m", "particlephysics_mcp_server"]
}
}
}
```
## Tools
### `search_particle`
Returns key properties inline.
- **query** (required): Name or symbol of the particle.
### `list_decays`
Returns all decay modes for a specified particle.
- **query** (required): Name or symbol of the particle.
## Local Testing
- To use the inspector, run the restart script:
```
./restart_mcp_inspector.sh
```
- To run end-to-end tests with Playwright:
```
uvx pytest tests/test_e2e_playwright.py
```
