Filesystem

Read and write files on the host machine. Useful for broad disk access outside an agent workspace. First run downloads the package via npx (requires network, ~5 s latency).

Slug: mcp-filesystem

Transport: stdio (local subprocess)

Auth: n/a (local subprocess — uses env vars, not an HTTP key)

Command: npx -y @modelcontextprotocol/server-filesystem@2026.1.14 <root-directory>

Setup: Replace <root-directory> in the args with the absolute path of the folder to expose (e.g. /home/user/docs). The server restricts all operations to that tree.
