MCP Filesystem Server
Anthropic's reference MCP server for filesystem access. Read, write, search, move, and list files inside a configured allowlist of directories. The canonical example for understanding how MCP tool exposure works in practice — most third-party MCP servers borrow its argument-validation patterns.

Recommended stack
- Commonly deployed withClaude Desktop
The reference deployment example for MCP. Configure filesystem allowlists in Claude Desktop's MCP config; the server starts on app launch.
- Commonly deployed withClaude Code
Same wiring as Claude Desktop. Most agent workflows that need local-file access pull this server in.
- Pairs withMCP Git Server
Together they give an agent full local-repo awareness — filesystem reads files, git reads metadata (status / diff / log / blame).
Works with
- Integrates withOpenHands
Filesystem MCP is non-optional for OpenHands — it's how the agent reads and writes project files. Allowlist limits blast radius.
Featured in these stacks
The L3 execution stacks that pick this tool as a recommended component, with the one-line note explaining the role it plays in each.
- Stack · L3·Workstation tier·Role: File access (the agent's hands on the codebase)Build a local coding-agent stack (May 2026)
The Anthropic reference filesystem MCP server with strict directory allowlisting. Required for OpenHands to read and write project files; allowlist limits blast radius when the agent goes off the rails.
- Stack · L3·Workstation tier·Role: MCP filesystem (file access with allowlisting)Build a memory-enabled local agent stack (May 2026)
Strict directory allowlist limits the agent's blast radius. Required for any agent that edits files; non-optional for a memory-enabled agent that may take destructive actions based on remembered context.
- Stack · L3·Workstation tier·Role: MCP filesystem (strict allowlist)Build a fully offline coding stack (May 2026)
Reference Anthropic filesystem MCP. Strict directory allowlisting limits the agent's blast radius — non-optional for offline deployments where the network can't catch a destructive mistake.
Pros
- Anthropic-maintained reference implementation
- Strict directory allowlisting prevents path-escape attacks
- Stdio + remote transport support
Cons
- No content-type heuristics — large binary files come through raw
- Requires per-directory configuration for each project
