README

A fast, configurable filesystem server for the Model Context Protocol (MCP), written in Rust.

fs-mcp-rs gives an MCP client a small set of filesystem tools while keeping access inside directories selected by the operator. It has no implicit filesystem root, no built-in personal path, and no writable default. The server starts only when you provide a configuration file.

Why one crate?

The public distribution is one crate and one executable, both named fs-mcp-rs. The protocol, policy, filesystem, search, and settings components remain separate Rust modules inside that crate. This keeps installation simple:

cargo install fs-mcp-rs

Users do not need to install or understand a graph of internal crates. The benchmark runner remains a development-only workspace member and is not included in the crates.io package.

Features

MCP over JSON-RPC HTTP POST and line-delimited STDIO (stdin/stdout).
Zero-install execution via npx fs-mcp-rs.
Explicit allow-list of one or more filesystem roots (via CLI positional arguments or TOML config).
Read-only mode for safe deployments.
Optional write, move, edit, directory creation, and removal operations.
Bounded reads, writes, search results, and concurrency.
Literal and regular-expression content search.
.gitignore support and configurable hidden-file handling.
Symlink traversal disabled by default.
Atomic file replacement and BLAKE3 hashes.
Optional arbitrary terminal command execution with time and output limits.
Persistent terminal sessions with incremental output cursors, long polling, stdin, process-tree termination, retention, and bounded buffers.
Concise tool execution logging ([OK] / [WARN]).
No telemetry and no automatic network discovery.

Requirements

Node.js (v18+) for npx execution, or Rust 1.85+ when building from source.
An MCP client that can connect via STDIO JSON-RPC or Streamable HTTP/JSON-RPC endpoint.
A configuration file or explicit root paths passed to the server.

Installation

Via npx (Zero Installation)

The easiest way to run fs-mcp-rs with any MCP client (such as Claude Desktop or Cursor) is using npx:

npx fs-mcp-rs /path/to/project

The npm package automatically downloads the appropriate precompiled binary for your operating system and architecture (Windows x64, Linux x64, macOS x64/arm64).

From crates.io

cargo install fs-mcp-rs
fs-mcp-rs --version

From source

git clone https://github.com/nihmadev/fs-mcp-rs.git
cd fs-mcp-rs
cargo build --release

The executable will be at target/release/fs-mcp-rs on Unix-like systems or target\release\fs-mcp-rs.exe on Windows.

Create a configuration

Copy configs/example.toml somewhere appropriate and edit it. The server intentionally has no default config path:

cp configs/example.toml fs-mcp-rs.toml

Windows PowerShell:

Copy-Item configs\example.toml fs-mcp-rs.toml

Minimal read-only configuration:

[server]
host = "127.0.0.1"
port = 8000
max_concurrency = 32
max_io_concurrency = 16

[filesystem]
roots = ["/home/alice/projects"]
read_only = true
max_read_bytes = 8388608
max_write_bytes = 8388608
