Pulseengine Mcp

mcp

Rust framework for Model Context Protocol

 

 

Rust framework for building Model Context Protocol servers and clients.

> [!NOTE] > Part of the PulseEngine toolchain. Provides the MCP implementation used across PulseEngine's AI-assisted development infrastructure.

Example

use pulseengine_mcp_macros::{mcp_server, mcp_tools};
use schemars::JsonSchema;
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize, JsonSchema)]
pub struct GreetParams {
    pub name: Option,
}

#[mcp_server(name = "My Server")]
#[derive(Default, Clone)]
pub struct MyServer;

#[mcp_tools]
impl MyServer {
    /// Greet someone by name
    pub async fn greet(&self, params: GreetParams) -> anyhow::Result {
        let name = params.name.unwrap_or_else(|| "World".to_string());
        Ok(format!("Hello, {name}!"))
    }
}

#[tokio::main]
async fn main() -> Result> {
    MyServer::configure_stdio_logging();
    MyServer::with_defaults().serve_stdio().await?.run().await
}

The #[mcp_server] and #[mcp_tools] macros generate the protocol implementation. Tool schemas are derived from your Rust types via JsonSchema.

Crates

| Crate | Description | | ------------------------------- | -------------------------------------------------- | | [mcp-protocol](mcp-protocol/) | MCP types, JSON-RPC, schema validation | | [mcp-server](mcp-server/) | Server infrastructure with McpBackend trait | | [mcp-client](mcp-client/) | Client for connecting to MCP servers | | [mcp-transport](mcp-transport/) | stdio, HTTP, WebSocket transports | | [mcp-auth](mcp-auth/) | Authentication, API keys, OAuth 2.1 | | [mcp-security](mcp-security/) | Input validation, rate limiting | | [mcp-logging](mcp-logging/) | Structured logging with credential sanitization | | [mcp-macros](mcp-macros/) | #[mcp_server], #[mcp_tools], #[mcp_resource] |

Examples

• [hello-world](examples/hello-world/) — Minimal server
• [hello-world-with-auth](examples/hello-world-with-auth/) — With authentication
• [resources-demo](examples/resources-demo/) — Resource templates with #[mcp_resource]
• [ui-enabled-server](examples/ui-enabled-server/) — MCP Apps extension (SEP-1865)

MCP Spec

Implements MCP 2025-11-25: tools, resources, prompts, completions, sampling, roots, logging, progress, cancellation, tasks, and elicitation.
