Mcp Server Filesystem

mcp-server-filesystem is an MCP server from ByteDance that gives coding agents read and write file access scoped to explicitly allowed directories.

About

ByteDance's mcp-server-filesystem gives coding agents read and write access to files under directories you explicitly allow. It is published on npm as @agent-infra/mcp-server-filesystem and requires a comma-separated allowed-directories argument that scopes every file operation. Developers use it so an agent can edit source, configs, and docs inside a chosen workspace without exposing the whole machine. It runs locally over stdio and also offers an SSE transport on a configurable localhost port.

  • Read/write filesystem access as MCP tools
  • Required allowed-directories argument scopes all operations
  • stdio and SSE transports (localhost port)
  • Runs locally via @agent-infra/mcp-server-filesystem

How can an agent safely edit files in a project without being granted access to the entire filesystem?

devops

Who is it for?

Agents that should edit source, configs, and docs inside a specific repo or scratch path without whole-machine access.

Skip if: Version control, backups, or cloud-drive sync, which it does not provide.

What you get

The agent reads and writes files only within the allowed directories you configure.

  • File reads and edits within the allowed directories
