## Description
NASA/JPL Solar System Dynamics + CNEOS MCP.

## Tools
Capabilities this server exposes over MCP:

- **get_small_body** — NASA/JPL Solar System Dynamics — look up an asteroid or comet by name or designation and return its orbit and physical parameters (eccentricity, semi-major axis, MOID, diameter, albedo, NEO/PHA flags). Keyless.
- **close_approaches** — NASA/JPL CNEOS — list near-Earth close approaches to Earth in a date range, with miss distance (AU), relative velocity (km/s), and absolute magnitude (size proxy). Keyless.
- **impact_risk** — NASA/JPL CNEOS Sentry — Earth impact risk for asteroids. Pass a designation for one object's cumulative impact probability, Palermo/Torino scale, diameter, and impact window; or omit it to list all currently-tracked objects above an impact-probability threshold. Keyless.
- **recent_fireballs** — NASA/JPL CNEOS — most recent atmospheric fireballs/bolides detected by U.S. Government sensors, with date, radiated and total impact energy (kilotons of TNT), location, altitude, and velocity. Keyless.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "jpl-ssd": {
    "command": "npx",
    "args": ["-y","@pipeworx/mcp-jpl-ssd"]
  }
}
```

## Documentation

## What Jpl Ssd does

Jpl Ssd MCP server exposes NASA and JPL datasets for small bodies and near-Earth objects through the Model Context Protocol. Its four pack-specific tools cover object properties, Earth close approaches, asteroid impact risk, and recently detected fireballs. No API key is required for these tools.

The server is suited to agents that need factual astronomy or planetary-defense data rather than general-purpose space calculations. Results include structured measurements such as orbital elements, miss distance, velocity, object size indicators, impact probabilities, and event energy.

## How it works

The service can be reached through a scoped Pipeworx gateway endpoint at `https://gateway.pipeworx.io/jpl-ssd/mcp`, or through the full gateway at `https://gateway.pipeworx.io/mcp`. The scoped endpoint lists this pack's tools directly, but it also exposes shared Pipeworx meta-tools. Those tools can route questions to other catalog sources through `ask_pipeworx`.

A local installation is also available as an MCP process communicating over standard input and output. The local process exposes only the Jpl Ssd tools and does not include the gateway's shared meta-tools or cross-catalog routing. The same capabilities can also be called over HTTP through the gateway's `/v1/tools/{tool}` endpoints.

## Setup and configuration

For an MCP client that supports remote endpoints, add the scoped URL as an MCP server. The README gives configuration examples for Claude Desktop, Cursor, and Windsurf. A full-gateway configuration is an alternative when an agent should access every Pipeworx source directly.

For local stdio use, run the package with `npx -y @pipeworx/mcp-jpl-ssd` and configure the client with the `npx` command and package argument. This mode does not require a Pipeworx account or a gateway round trip. The gateway also allows initial calls without an account.

No environment variables or API credentials are documented as required.

## Tools and capabilities

- `get_small_body` accepts an asteroid or comet name or designation. It returns orbital and physical information, including eccentricity, semi-major axis, MOID, diameter, albedo, and NEO or PHA flags.
- `close_approaches` searches near-Earth approaches within a date range. Results include Earth miss distance in AU, relative velocity in km/s, and absolute magnitude as a size proxy.
- `impact_risk` uses NASA/JPL CNEOS Sentry data. With a designation, it returns an object's cumulative impact probability, Palermo and Torino scale values, diameter, and impact window. Without one, it can list tracked objects above an impact-probability threshold.
- `recent_fireballs` returns recent atmospheric fireball or bolide observations from U.S. Government sensors, including date, location, altitude, velocity, and radiated and total impact energy in kilotons of TNT.

## Limitations and notes

The gateway and local modes expose different tool scopes. A gateway connection adds shared Pipeworx tools, while the standalone process is limited to this pack. The exact gateway tool list can change; its `initialize` response is authoritative for the active connection. Data comes from the referenced NASA/JPL services, so results reflect those sources and their available records.
