| Tool | Description |

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"cactus": {
"url": "https://gateway.pipeworx.io/cactus/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 808+ 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 Cactus data" })
The gateway picks the right tool and fills the arguments automatically.
