csv-mcp

MCP server: parse and serialize CSV. RFC 4180 with pragmatic flexibility — configurable delimiter, CRLF or LF endings, double-quote escaping, optional header row that emits objects.

Tools

parse

{ "text": "name,age\nMukunda,30\nAlex,25", "header": true }

→ { "rows": [ { "name": "Mukunda", "age": "30" }, { "name": "Alex", "age": "25" } ] }

Without header, returns an array of arrays. Custom delimiter via delimiter: ";".

stringify

{ "rows": [ { "name": "x", "age": "1" }, { "name": "y", "age": "2" } ] }

→

name,age
x,1
y,2

Object rows auto-emit a header. Pass header: ["col1","col2"] to fix column order.

Configure

{ "mcpServers": { "csv": { "command": "npx", "args": ["-y", "@mukundakatta/csv-mcp"] } } }
