Filesystem MCP Server
Maintained reference server for explicitly permitted local directories and file operations. Use this record to separate documented interface facts from proposed evaluation steps, and preserve the checked date with the source links when the provider changes its setup.

Setup and connection.
The documented interface, authentication and installation path.
- Connection / transport
- stdio
- Authentication
- No API key; local process and directory access.
Configure the npm package with absolute allowed directories; Roots-capable clients can replace the list. Confirm effective roots before any write.
Setup reference ↗Documented setup example. Review the source and credentials before running; this command was not executed for this article.
npx -y @modelcontextprotocol/server-filesystem /path/to/allowed/dirWhat it actually exposes.
Concrete capabilities with maintainer sources.
Directory control
Use CLI paths or client Roots; Roots replace the startup list.
Documentation ↗Edits
Create, move, edit and write files with tool annotations.
Documentation ↗Evidence and method.
What was checked and what was not tested.

Source method
Public maintainer documentation and repositories. This is not a hands-on product review.
WHEN
Last checked 2026-10-01
Setup examples are documented examples. Suggested trials and comparison advice are editorial guidance.
Sources support the adjacent factual statements. A source review does not establish uptime, performance, security or current account eligibility. Read the editorial policy.
Try a specific task.
A bounded evaluation you can reproduce in your own environment.
Review a draft folder (proposed; not tested)
Suggested evaluation, not an observed test result.
- Grant one dedicated test folder.
- Request an inventory and dry-run diff.
- Approve one edit and reread the file.
What to inspect: Only the requested file changes; proposed validation, not observed.
Workflow reference ↗Permissions and limitations.
Read these constraints before granting access.
Initialization requires at least one allowed directory from arguments or client Roots.
Boundary reference ↗Writes can overwrite files; editorial recommendation: start in a disposable folder.
Boundary reference ↗Decide by workflow.
Make the expected output explicit before you connect.
Only the requested file changes; proposed validation, not observed.
Keep the task inputs, tool calls, output and any errors together when you evaluate. The trial above is a proposal, not a recorded result.
Compare the alternatives.
Specific reasons to choose another route, with the tradeoff shown.
| Alternative | Choose it when | Tradeoff |
|---|---|---|
| Git MCP Server | Editorial inference: you need Git staging and history. | It works on repositories rather than generic file folders. Documentation ↗ |
| Memory MCP Server | Editorial inference: you need durable facts and relationships. | It is a graph store, not a document editor. Documentation ↗ |
Questions before setup.
Answers specific to this implementation.
Why did paths change?
Client Roots replace startup paths.
Documentation ↗
Is it read-only?
No; use filesystem permissions or read-only mounts when needed.
