Build

# build mcp server
cargo build --package cardea-calculator --release

Run

Now, let's start the mcp server. You can choose to start the server with different transport types by specifying the --transport CLI option. The default transport type is stream-http. In addition, you can also specify the socket address to bind to by specifying the --socket-addr CLI option. The default socket address is 127.0.0.1:8001.

# run mcp server (stream-http)
./target/release/cardea-calculator --transport stream-http

# run mcp server (sse)
./target/release/cardea-calculator --transport sse

If start successfully, you will see the following output:

Calculator MCP server is listening on 127.0.0.1:8001
