VizieR MCP — CDS astronomical catalogue access.

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ 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).
`object`	Query by object name (resolved via SIMBAD/NED).

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 673+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

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.
