Quick Start With Claude Desktop

1. Build the Server (Counter Example)

   cargo build --release --example servers_std_io
   

   This builds a standard input/output MCP server binary.

2. Add or update this section in your ~/.config/claude-desktop/config.toml

   {
       "mcpServers": {
           "counter": {
           "command": "PATH-TO/rust-sdk/target/release/examples/servers_std_io.exe",
           "args": []
           }
       }
   }
   

3. Once Claude Desktop is running, try chatting:

   counter.say_hello
   

   Or test other tools like:

   counter.increment
   counter.get_value
   counter.sum {"a": 3, "b": 4}
