mcp-csv

CSV <-> JSON MCP.

Part of Pipeworx — an MCP gateway connecting AI agents to 1148+ live data sources.

Tools

| Tool | Description | |------|-------------| | csv_to_json | Parse RFC 4180 CSV into JSON (keyless, offline). With header true (default) the first row becomes object keys; otherwise rows are returned as arrays. Handles quoted fields, escaped quotes, and embedded commas/newlines. Set delimiter for TSV etc. | | json_to_csv | Serialize an array of JSON objects (or arrays) to CSV (keyless, offline). Object keys become the header (union of all keys, in first-seen order). Fields are quoted when needed. |

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

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

Or connect to the full Pipeworx gateway for access to all 1148+ 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 Csv data" })

The gateway picks the right tool and fills the arguments automatically.
