CDS VizieR — astronomical catalogue server (tens of thousands of catalogues)
Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.
Tools
| Tool | Description |
|---|---|
catalogs | Search VizieR catalogue metadata. |
query_catalog | Query rows of a single catalogue (e.g. "I/345/gaia2"). |
cone_search | Cone search around (RA, Dec). |

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"vizier": {
"url": "https://gateway.pipeworx.io/vizier/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 250+ 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 Vizier data" })
The gateway picks the right tool and fills the arguments automatically.
