MCP Server implementation for Poem
Example
[dependencies]
poem-mcpserver.workspace = "*"
serde = { version = "1.0", features = ["derive"] }
schemars = "1.0"
use poem_mcpserver::{stdio::stdio, tool::Text, McpServer, Tools};
struct Counter {
count: i32,
}
/// This server provides a counter tool that can increment and decrement values.
///
/// The counter starts at 0 and can be modified using the 'increment' and
/// 'decrement' tools. Use 'get_value' to check the current count.
#[Tools]
impl Counter {
/// Increment the counter by 1
async fn increment(&mut self) -> Text<i32> {
self.count += 1;
Text(self.count)
}
/// Decrement the counter by 1
async fn decrement(&mut self) -> Text<i32> {
self.count -= 1;
Text(self.count)
}
/// Get the current counter value
async fn get_value(&self) -> Text<i32> {
Text(self.count)
}
}
#[tokio::main]
async fn main() -> std::io::Result<()> {
stdio(McpServer::new().tools(Counter { count: 0 })).await
}
