一个基于tokio异步运行时的官方Model Context Protocol SDK实现。
|
||||
一个基于 tokio 异步运行时的官方 Model Context Protocol SDK 实现。
|
||||
|
||||
本项目使用了以下开源库:
|
||||
|
||||
- [rmcp](crates/rmcp): 实现 RMCP 协议的核心库 (详见：[rmcp](crates/rmcp/README.md))
|
||||
- [rmcp-macros](crates/rmcp-macros): 一个用于生成 RMCP 工具实现的过程宏库。 (详见：[rmcp-macros](crates/rmcp-macros/README.md))
|
||||
|
||||
## 使用
|
||||
|
||||
### 导入
|
||||
```toml
|
||||
rmcp = { version = "0.1", features = ["server"] }
|
||||
## 或者开发者频道
|
||||
rmcp = { version = "0.2.0", features = ["server"] }
|
||||
## 或使用最新开发版本
|
||||
rmcp = { git = "https://github.com/modelcontextprotocol/rust-sdk", branch = "main" }
|
||||
```
|
||||
|
||||
### 快速上手
|
||||
一行代码启动客户端：
|
||||
```rust
|
||||
### 第三方依赖库
|
||||
基本依赖:
|
||||
- [tokio required](https://github.com/tokio-rs/tokio)
|
||||
- [serde required](https://github.com/serde-rs/serde)
|
||||
|
||||
### 构建客户端
|
||||
<details>
|
||||
<summary>构建客户端</summary>
|
||||
|
||||
```rust, ignore
|
||||
use rmcp::{ServiceExt, transport::{TokioChildProcess, ConfigureCommandExt}};
|
||||
use tokio::process::Command;
|
||||
|
||||
let client = ().serve(TokioChildProcess::new(Command::new("npx").configure(|cmd| {
|
||||
cmd.arg("-y").arg("@modelcontextprotocol/server-everything");
|
||||
}))?).await?;
|
||||
#[tokio::main]
|
||||
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
||||
let client = ().serve(TokioChildProcess::new(Command::new("npx").configure(|cmd| {
|
||||
cmd.arg("-y").arg("@modelcontextprotocol/server-everything");
|
||||
}))?).await?;
|
||||
Ok(())
|
||||
}
|
||||
```

#### 1. 构建传输层
|
||||
### 构建服务端
|
||||
|
||||
<details>
|
||||
<summary>构建传输层</summary>
|
||||
|
||||
```rust, ignore
|
||||
use tokio::io::{stdin, stdout};
|
||||
let transport = (stdin(), stdout());
|
||||
```
|
||||
|
||||
传输层类型必须实现 [`IntoTransport`](crate::transport::IntoTransport) trait, 这个特性允许分割成一个sink和一个stream。
|
||||
</details>
|
||||
|
||||
对于客户端, Sink 的 Item 是 [`ClientJsonRpcMessage`](crate::model::ClientJsonRpcMessage)， Stream 的 Item 是 [`ServerJsonRpcMessage`](crate::model::ServerJsonRpcMessage)
|
||||
<details>
|
||||
<summary>构建服务</summary>
|
||||
|
||||
对于服务端, Sink 的 Item 是 [`ServerJsonRpcMessage`](crate::model::ServerJsonRpcMessage)， Stream 的 Item 是 [`ClientJsonRpcMessage`](crate::model::ClientJsonRpcMessage)
|
||||
|
||||
##### 这些类型自动实现了 [`IntoTransport`](crate::transport::IntoTransport) trait
|
||||
1. 已经同时实现了 [`Sink`](futures::Sink) 和 [`Stream`](futures::Stream) trait的类型。
|
||||
2. 由sink `Tx` 和 stream `Rx`组成的元组: `(Tx, Rx)`。
|
||||
3. 同时实现了 [`tokio::io::AsyncRead`] 和 [`tokio::io::AsyncWrite`] trait的类型。
|
||||
4. 由 [`tokio::io::AsyncRead`] `R `和 [`tokio::io::AsyncWrite`] `W` 组成的元组: `(R, W)`。
|
||||
|
||||
例如，你可以看到我们如何轻松地通过TCP流或http升级构建传输层。 [examples](examples/README.md)
|
||||
|
||||
#### 2. 构建服务
|
||||
你可以通过 [`ServerHandler`](crates/rmcp/src/handler/server.rs) 或 [`ClientHandler`](crates/rmcp/src/handler/client.rs) 轻松构建服务
|
||||
You can easily build a service by using [`ServerHandler`](crates/rmcp/src/handler/server.rs) or [`ClientHandler`](crates/rmcp/src/handler/client.rs).
|
||||
|
||||
```rust, ignore
|
||||
let service = common::counter::Counter::new();
|
||||
```
|
||||
</details>
|
||||
|
||||
<details>
|
||||
<summary>启动服务端</summary>
|
||||
|
||||
#### 3. 把他们组装到一起
|
||||
```rust, ignore
|
||||
// 这里会自动完成初始化流程
|
||||
// this call will finish the initialization process
|
||||
let server = service.serve(transport).await?;
|
||||
```
|
||||
</details>
|
||||
|
||||
#### 4. 与服务交互
|
||||
一旦服务初始化完成，你可以发送请求或通知：
|
||||
<details>
|
||||
<summary>与服务端交互</summary>
|
||||
|
||||
Once the server is initialized, you can send requests or notifications:
|
||||
|
||||
```rust, ignore
|
||||
// 请求
|
||||
// request
|
||||
let roots = server.list_roots().await?;
|
||||
|
||||
// 或发送通知
|
||||
// or send notification
|
||||
server.notify_cancelled(...).await?;
|
||||
```
|
||||
</details>
|
||||
|
||||
<details>
|
||||
<summary>等待服务停止</summary>
|
||||
|
||||
#### 5. 等待服务关闭
|
||||
```rust, ignore
|
||||
let quit_reason = server.waiting().await?;
|
||||
// 或取消它
|
||||
// 或将其取消
|
||||
let quit_reason = server.cancel().await?;
|
||||
```
|
||||
|
||||
### 使用宏来声明工具
|
||||
使用 `toolbox` 和 `tool` 宏来快速创建工具。
|
||||
|
||||
请看这个[文件](examples/servers/src/common/calculator.rs)。
|
||||
```rust, ignore
|
||||
use rmcp::{ServerHandler, model::ServerInfo, schemars, tool};
|
||||
|
||||
use super::counter::Counter;
|
||||
|
||||
#[derive(Debug, serde::Deserialize, schemars::JsonSchema)]
|
||||
pub struct SumRequest {
|
||||
#[schemars(description = "the left hand side number")]
|
||||
pub a: i32,
|
||||
#[schemars(description = "the right hand side number")]
|
||||
pub b: i32,
|
||||
}
|
||||
#[derive(Debug, Clone)]
|
||||
pub struct Calculator;
|
||||
|
||||
// create a static toolbox to store the tool attributes
|
||||
#[tool_router]
|
||||
impl Calculator {
|
||||
// async function
|
||||
#[tool(description = "Calculate the sum of two numbers")]
|
||||
async fn sum(&self, #[tool(aggr)] SumRequest { a, b }: SumRequest) -> String {
|
||||
(a + b).to_string()
|
||||
}
|
||||
|
||||
// sync function
|
||||
#[tool(description = "Calculate the sum of two numbers")]
|
||||
fn sub(
|
||||
&self,
|
||||
#[tool(param)]
|
||||
// this macro will transfer the schemars and serde's attributes
|
||||
#[schemars(description = "the left hand side number")]
|
||||
a: i32,
|
||||
#[tool(param)]
|
||||
#[schemars(description = "the right hand side number")]
|
||||
b: i32,
|
||||
) -> String {
|
||||
(a - b).to_string()
|
||||
}
|
||||
}
|
||||
|
||||
// impl call_tool and list_tool by querying static toolbox
|
||||
#[tool_handler]
|
||||
impl ServerHandler for Calculator {
|
||||
fn get_info(&self) -> ServerInfo {
|
||||
ServerInfo {
|
||||
instructions: Some("A simple calculator".into()),
|
||||
..Default::default()
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
你要做的唯一事情就是确保函数的返回类型实现了 `IntoCallToolResult`。
|
||||
|
||||
你可以为返回类型实现 `IntoContents`，那么返回值将自动标记为成功。
|
||||
|
||||
如果返回类型是 `Result<T, E>`，其中 `T` 与 `E` 都实现了 `IntoContents`，那也是可以的。
|
||||
|
||||
### 管理多个服务
|
||||
在很多情况下你需要在一个集合中管理多个服务，你可以调用 `into_dyn` 来将服务转换为相同类型。
|
||||
```rust, ignore
|
||||
let service = service.into_dyn();
|
||||
```
|
||||
|
||||
</details>
|
||||

||||
