Summary
Connects Claude to the SIMBAD astronomical database maintained by CDS, giving you programmatic access to roughly 14 million celestial objects. You get four tools: object lookup by identifier (like M31 or HD 209458), cone search by coordinates and radius, raw ADQL TAP queries for complex filtering, and sim-script execution for SIMBAD's native query language. Runs through Pipeworx's gateway infrastructure, so you can either connect to this source alone or tap into their full catalog of 600+ data sources. Useful if you're building astronomy workflows, cross-referencing observations, or need to pull stellar data into an AI context without scraping CDS pages manually.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

mcp-simbad
SIMBAD MCP — CDS astronomical object database.
Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.
Tools
| Tool | Description |
|---|---|
object | Resolve and fetch the basic record for an object identifier (e.g. "M31", "HD 209458"). |
script | Run a SIMBAD sim-script. See https://simbad.cds.unistra.fr/simbad/sim-fscript. |
tap | ADQL TAP query against the SIMBAD database (sync). Returns JSON by default. |
cone_search | Objects within a radius of (RA, Dec) decimal degrees. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"simbad": {
"url": "https://gateway.pipeworx.io/simbad/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Simbad data" })
The gateway picks the right tool and fills the arguments automatically.
