mcp-server-rust

A simple Rust function integrated with an MCP client. ## Step 1: Relase the Rust & Javascript/TS code ### Release ```sh 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: ```json { "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` (source: https://modelcontextprotocol.info/docs/quickstart/user/#2-add-the-filesystem-mcp-server) ## Step 3: Claude Desktop Start Claude Desktop  <sub>please note the additional mcp server icon in the frontend<sub> Agree to use the mcp server function:  Observe the mcp server function:  ### Video Watch the video tutorial here: [YouTube video](https://youtu.be/DlD7uWniNyE) ## Misc ### Test the rust code ```sh npm run test:rust ``` or ```sh cd src/lib/rust-functions-lib cargo test && cargo fmt --all -- --check ``` ### Clean the output files and folders ```sh npm run clean ``` ### Build the rust code - alternatives npm ```sh npm run build:wasm ``` Alternative approach using wasm tool ```sh cd src/lib/rust-functions-lib wasm-pack build --target bundler ``` ### Build only ts code (npm) ```sh npm build ``` ### Copy build Rust code manual copy to the correct location - included in `npm run build:wasm:release` ```sh 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
