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 PATH-TO/claude_desktop_config.json

   Windows

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

   MacOS/Linux

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

3. Ensure that the MCP UI elements appear in Claude Desktop The MCP UI elements will only show up in Claude for Desktop if at least one server is properly configured. It may require to restart Claude for Desktop.

4. 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}
