CSV Tools tools (3)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

parse_csv
Parse a CSV string into structured rows. Handles quoted fields with embedded commas, escaped double quotes, CRLF/LF newlines, and a leading BOM. Returns headers + rows-as-objects when has_header is true (default), or raw arrays otherwise.
pluck_columns
Reduce already-parsed rows (objects keyed by header) to just the named columns. Useful when CSV has many columns and you only need a few.
to_csv
Serialize rows to a CSV string with proper quoting. Accepts arrays of arrays or arrays of objects. If headers are provided, the first row is the header line.

How CSV Tools compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 92/100; higher than 90% of 48,273 servers
Tools: 3; the typical server has 7
Tools that change things: 0%; typical: 0%. Fewer write tools means less an agent can break

What its tools let an agent do: 3 read

Install CSV Tools in Claude Code, Cursor or VS Code

Runs npx -y @mukundakatta/csv-tools-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the CSV Tools repository's README, as published. We do not edit it. Read it on GitHub

mcp-stack

Fourteen small MCP servers for everyday LLM / RAG / agent work. Each ships independently on npm, listed in the official MCP Registry, and is callable from Claude Desktop, Cursor, Cline, Windsurf, Zed, and any other MCP-compatible client.

RAG / agent helpers

Reliable transforms LLMs reach for tools instead of imagining

Sibling libraries

The first four wrap or re-implement logic from the user's Rust + Python work:

ragdrift-py (PyPI) — five-dimensional drift detection

ragdrift (crates.io) /

stopstream, citecite, ragmetric — pure-Rust crates from the rust-llm-stack workspace

embedrank, promptbudget,

The MCP servers are independent: they implement the logic they need in plain JavaScript so installing them doesn't pull a Rust toolchain.

Install (any of them)

Add to your MCP client config. Example for Claude Desktop:
