filesystem

filesystem is an MCP server for Cursor from mjdevaccount/AIStack-MCP. Its token cost is not measured, scanned A, a copy of filesystem, MIT.

A local file-access server that lets an agent read and write files in the allowed workspace directory. It runs through the Model Context Protocol, a standard way for AI tools to connect to external services.

In plain words
What is it for?
It is for reading and changing files under the configured local directory.
Why use it?
It gives the agent access to project files without granting access to every location on the computer.

MCP server for Cursor

Written for Cursor: installed under .cursor/. Also seen: listed in .cursor/mcp.json.

One of 5 entries in mcp.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

Good fit It is for reading and changing files under the configured local directory.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

filesystem scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to filesystem — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What else mcp.json configures

This page is one entry in a file that holds 5. Installing the file brings all of them; each is measured and scanned on its own page.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
