Official tool maintained by Anthropic, PBC.

The canonical building block for local AI workflows. Every developer benefits from an AI that can read, write, and organize files — this is the foundational skill that makes Claude Code-like workflows possible with any MCP-compatible tool.

Any developer wanting Claude to read, write, or manage local files as part of a workflow — universal prerequisite for most AI-assisted development setups.

Reviewer notes

Source Reviewed review. These are observations, not a security certification.

The reference implementation — published by Anthropic. 1.56M monthly downloads, 50,926 GitHub stars (parent repo). MIT license. Directory access controlled via explicit allowlist. Built-in safety: will not operate without allowed directory configured. Full read/write within scope — appropriate for the domain.

Full read/write/delete within configured scope. Directory allowlist provides containment, but misconfiguring (e.g. allowing / or /home) would be catastrophic. Enterprise must enforce strict directory scoping policy. Minimal reputable dependencies. Anthropic maintainer — highest trust.

2026-04-02: LIMITATION: Misconfiguring the directory allowlist (e.g., allowing / or /home) would expose the entire filesystem to read/write/delete. Enterprise deployments must enforce strict directory scoping.
