Filesystem (official) (modelcontextprotocol) MCP Server

@modelcontextprotocol/server-filesystem npm v2026.7.10 Official

Published by Model Context Protocol — an official vendor package. A brand name in a package name proves nothing; this one is verified by npm scope ownership or publish provenance.

The official MCP filesystem server: read, write, search and manage local files with configurable access roots.

Trust grade

100/100

Last scanned 2026-07-22

Trust

A · 100/100

How safe the published surface and source look. Deterministic; every point is auditable.

Capability

Minimal

Blast radius if it went rogue — what the server’s tools could reach. Independent of trust.

Coverage

Source

How much the scan could actually inspect. Shallow coverage is stated, never hidden.

A Why this grade

Started at 100 and nothing was deducted: the deterministic scan raised no scored threat in the published surface it inspected. Capability observations and advisory notes are recorded but never lower the score.

Findings 0

✓ No findings. The scan raised nothing on this surface — see Coverage for how deep it could look.

What this scan could not see

No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".

Versions

Scan history per published version. The engine is deterministic — the same version always yields the same score, so a changed score means the package itself changed.

Version	Score	Findings	Engine	Scanned
`v2026.7.10` latest	A 100/100	0	1.5.0	2026-07-22
