Converts between CSV and JSON.
README
CSV <-> JSON MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ 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 1394+ 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.
