# spacetrack-mcp

MCP server for NASA Space-Track — the first of its kind.

Wraps the [Space-Track REST API](https://www.space-track.org) with three tools
for use in Claude Desktop, AMOA, or any MCP-compatible client.

## Tools

| Tool | Description |
|---|---|
| `tle_lookup` | Fetch latest TLE for a satellite by NORAD ID |
| `conjunction_query` | Fetch recent CDMs (collision risk data) |
| `satcat_search` | Search satellite catalog by name |

## Install

```bash
uvx spacetrack-mcp
```

## Claude Desktop config

Add to `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "spacetrack": {
      "command": "uvx",
      "args": ["spacetrack-mcp"],
      "env": {
        "SPACETRACK_USERNAME": "your_email",
        "SPACETRACK_PASSWORD": "your_password"
      }
    }
  }
}
```

## Credentials

Register free at [space-track.org](https://www.space-track.org).
CDM access requires a separate request — see Space-Track documentation.

## Rate limits

Space-Track enforces 30 req/min, 300 req/hr. The server caches responses
with diskcache to stay within limits during development.
