# 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 …
