### Description (declared)

# NASA Exoplanet Archive MCP Server

An MCP server that gives AI assistants direct access to NASA's Exoplanet Archive — the authoritative database of every confirmed exoplanet, candidate planet, and host star. Built on the archive's TAP (Table Access Protocol) service with full ADQL query support.

## What can you do with it?

Once connected, you can ask your AI assistant questions like:

- *"Find rocky planets in the habitable zone within 50 parsecs of Earth"*
- *"What do we know about the TRAPPIST-1 system?"*
- *"How many exoplanets has TESS discovered? Break it down by year."*
- *"Show me planets with atmospheric spectroscopy data available"*
- *"Compare the orbital parameters of all planets around Kepler-90"*
- *"What's the mass-radius distribution of transiting planets discovered after 2020?"*

The server handles everything — name resolution, query construction, pagination, error handling — so the AI can focus on answering the question.

## Available Tools

| Tool | Description |
|------|-------------|
| **search_planets** | Search confirmed exoplanets with flexible filters (radius, mass, temperature, distance, discovery method, facility, year, and more). The primary tool for most questions. |
| **get_planet** | Get comprehensive details for a single planet — orbital, physical, stellar, and discovery properties with uncertainties. |
| **resolve_name** | Translate any name or catalog ID (TIC, KOI, Gaia, 2MASS, HD, HIP) to the canonical archive name. Handles common issues like missing spaces in planet names. |
| **list_tables** | Discover all 40+ tables in the archive — confirmed planets, TESS candidates, Kepler KOIs, transit spectroscopy, microlensing, time series, and more. |
| **list_columns** | Explore the 300+ available columns for any table, filterable by category (orbital, physical, stellar, discovery, system, photometry). |
| **run_query** | Execute raw ADQL queries for full flexibility — aggregations, JOINs, spatial/cone searches, or querying any table …
