@mukundakatta/csv-tools-mcp

MCP server for reliable CSV parsing and generation. Three tools:

• parse_csv(text, has_header?, delimiter?) — RFC 4180 parsing with proper handling of quoted fields, embedded commas, escaped double quotes (""), CRLF/LF, and a leading BOM. Returns headers + objects (or raw arrays).
• to_csv(rows, headers?, delimiter?) — serialize arrays-of-arrays or arrays-of-objects with correct quoting.
• pluck_columns(rows, columns) — reduce parsed rows to just the named columns.

Why this exists

LLMs ask for "the CSV parsed" and silently miss edge cases: a comma inside a quoted field, an escaped quote, a BOM that turns the first column header into name. Routing through this MCP server gives you state-machine-correct parsing instead of best-effort imagination.
