CSV Editor - AI-Powered CSV Processing via MCP

Stateful CSV editing for AI assistants. CSV Editor is an MCP server that gives Claude, ChatGPT, Cursor, Windsurf, and other MCP clients a full suite of CSV operations — with sessions, undo/redo, and auto-save built in. Most data MCPs are analyze-only; this one lets the AI edit.

🆕 What's new in v2.0.0 (April 2026)

FastMCP 3.x — migrated from FastMCP 2 to 3.2, aligning with MCP spec 2025-11-25.
Python 3.11+ required (was 3.10+). Tested against 3.11 / 3.12 / 3.13 / 3.14.
--transport sse removed. Use --transport http (Streamable HTTP) for remote deployments. SSE was deprecated by FastMCP 3.
Dependency refresh: pydantic 2.13, pyarrow 23, httpx 0.28.
New CSV_EDITOR_CSV_HISTORY_DIR env var for configuring the history directory.
First-class CI test matrix on GitHub Actions.

Users who pinned csv-editor>=1,<2 are unaffected and will continue to receive 1.x patches if needed. See CHANGELOG.md for the full list of breaking changes.

🎯 Why CSV Editor?

The Problem

AI assistants struggle with complex data operations - they can read files but lack tools for filtering, transforming, analyzing, and validating CSV data efficiently.

The Solution

CSV Editor bridges this gap by providing AI assistants with 39 specialized tools for CSV operations, turning them into powerful data analysts that can:

Clean messy datasets in seconds
Perform complex statistical analysis
Validate data quality automatically
Transform data with natural language commands
Track all changes with undo/redo capabilities

Key differentiators vs. other CSV / tabular MCPs

Capability	CSV Editor	DuckDB / Polars MCPs	Most pandas-based MCPs
Stateful editing (load → mutate → save)	✅	Read-only or single-shot	Partial
Undo / redo with snapshots	✅	❌	❌
Multi-session isolation	✅	Limited	Limited
Auto-save with strategies	✅ (overwrite / backup / versioned / custom)	❌	❌
Quality scoring & validation	✅	SQL-only	Via separate tools
File-size sweet spot	<1 GB (pandas)	50 GB+ (streaming SQL)	Small–medium
Best for	Edit-and-review workflows	Large-file analytics	Quick analysis

When to pick CSV Editor: you want the AI to make changes to a CSV and iterate, not just answer questions about it. If your workload is read-only analytics on multi-GB files, a DuckDB-based MCP is likely a better fit; CSV Editor's DuckDB/Polars engine support is tracked on the roadmap.

⚡ Quick Demo

# Your AI assistant can now do this:
"Load the sales data and remove duplicates"
"Filter for Q4 2024 transactions over $10,000"  
"Calculate correlation between price and quantity"
"Fill missing values with the median"
"Export as Excel with the analysis"

# All with automatic history tracking and undo capability!
