What is Mcp Server Rust

mcp-server-rust is a local server built using Rust programming language, designed to integrate with an MCP client. It allows users to execute Rust functions seamlessly within the MCP framework.

Use cases

Use cases for mcp-server-rust include executing complex algorithms within an MCP environment, enhancing the performance of applications that utilize Rust for backend processing, and providing a local server solution for development and testing.

How to use

To use mcp-server-rust, follow these steps: 1. Release the Rust and JavaScript/TypeScript code by running ‘npm run build:wasm:release’ and ‘npm install’. 2. Create a configuration file for Claude Desktop with the necessary command and arguments. 3. Start Claude Desktop and agree to use the MCP server function.

Key features

Key features of mcp-server-rust include: easy integration with MCP clients, support for Rust functions, a straightforward setup process, and the ability to run tests on Rust code.

Where to use

mcp-server-rust can be used in various fields such as software development, particularly in applications that require high-performance computations or integrations with machine learning models.

A simple Rust function integrated with an MCP client.

Step 1: Relase the Rust & Javascript/TS code

Release

npm run build:wasm:release // release rust code
npm install // create javascript file and install all npm dependencies

Step 2: Claude Desktop Configuration

Create a configuration file at:

{
  "mcpServers": {
    "mcp-server": {
      "command": "node",
      "args": [
        "[your local path]/mcpserver/build/index.js"
      ]
    }
  }
}

locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Misc

Test the rust code

npm run test:rust

or

cd src/lib/rust-functions-lib
cargo test && cargo fmt --all -- --check

Clean the output files and folders

npm run clean

Build the rust code - alternatives

npm

npm run build:wasm

Alternative approach using wasm tool

cd src/lib/rust-functions-lib
wasm-pack build --target bundler

Build only ts code (npm)

npm build

Copy build Rust code

manual copy to the correct location - included in npm run build:wasm:release

mkdir -p build/lib/rust-functions-lib/pkg && cp src/lib/rust-functions-lib/pkg/rust_funcations_lib.js build/lib/rust-functions-lib/pkg/rust_funcations_lib.js

Rust import failed

issue:

solution:

run npm run build:wasm:release to release the wasm-binding the factorial import depends on
