Prism MCP SDK for Rust

prism-mcp-rs is a production-grade Rust implementation of the Model Context Protocol (MCP) SDK with enterprise-class features for building secure, scalable MCP servers and clients.

Why Prism MCP?

The first MCP SDK designed for production AI systems. While other implementations focus on basic protocol compliance, Prism MCP brings enterprise-grade reliability patterns, zero-downtime operations, and plugin ecosystems that scale.

Built for the AI-first world: Where services need to be fault-tolerant, discoverable, and composable. Where hot-swapping capabilities matters more than cold starts. Where observability isn't optional—it's survival.

From prototype to production in minutes: Clean APIs that hide complexity, but expose power when you need it.

Core Differentiators

1. Advanced Resilience Patterns

Circuit Breaker Pattern: Automatic failure isolation preventing cascading failures
Adaptive Retry Policies: Smart backoff with jitter and error-based retry decisions
Health Check System: Multi-level health monitoring for transport, protocol, and resources
Graceful Degradation: Automatic fallback strategies when services become unavailable

2. Enterprise Transport Features

Streaming HTTP/2: Full multiplexing, server push, and flow control support
Adaptive Compression: Dynamic selection of Gzip, Brotli, or Zstd based on content analysis
Chunked Transfer Encoding: Efficient handling of large payloads with streaming
Connection Pooling: Intelligent connection reuse with keep-alive management
TLS/mTLS Support: Enterprise-grade security with certificate validation

3. Plugin System Architecture

Hot Reload Support: Update plugins without service interruption
ABI-Stable Interface: Binary compatibility across Rust versions
Plugin Isolation: Sandboxed execution with resource limits
Dynamic Discovery: Runtime plugin loading with dependency resolution
Lifecycle Management: Automated plugin health monitoring and recovery

4. Protocol Extensions

Schema Introspection: Complete runtime discovery of server capabilities
Batch Operations: Efficient bulk request processing with transaction support
Progressive Content Delivery: Streaming responses for large datasets
Rich Metadata Support: Comprehensive annotations and capability negotiation
Custom Method Extensions: Seamless protocol extensibility

5. Production Observability

Structured Logging: Contextual tracing with correlation IDs
Metrics Collection: Performance counters, histograms, and gauges
Distributed Tracing: OpenTelemetry integration for request flow analysis
Error Forensics: Detailed error context with stack traces and recovery hints

Technical Architecture

Core Components

Component	Description	Key Features

Clean & Simple API

30-Second Server Setup

use prism_mcp_rs::prelude::*;

#[derive(Clone)]
struct SystemTools;

#[async_trait]
impl ToolProvider for SystemTools {
    async fn call_tool(&self, request: CallToolRequest) -> McpResult<CallToolResult> {
        match request.name.as_str() {
            "system_info" => Ok(CallToolResult::text(format!(
                "Host: {}, OS: {}", 
                gethostname::gethostname().to_string_lossy(),
                std::env::consts::OS
            ))),
            _ => Err(McpError::invalid_request("Unknown tool"))
        }
    }

    async fn list_tools(&self) -> McpResult<ListToolsResult> {
        Ok(ListToolsResult::from_tools(vec![
            Tool::new("system_info", "Get system information")
        ]))
    }
}

#[tokio::main]
async fn main() -> McpResult<()> {
    McpServer::builder()
        .with_tool_provider(SystemTools)
        .with_stdio_transport()
        .build()
        .await?
        .run()
        .await
}

Enterprise-Grade Client

use prism_mcp_rs::client::*;

let client = ClientSession::builder()
    .with_circuit_breaker() // Auto fault isolation
    .with_adaptive_retries() // Smart backoff
    .with_health_monitoring() // Continuous health checks
    .connect_stdio("./server")
    .await?;

// Resilient operations with automatic recovery
let tools = client.list_tools().await?;
let result = client.call_tool("system_info", json!({})).await?;

Hot-Reloadable Plugins

use prism_mcp_rs::plugin::*;

#[plugin]
struct WeatherPlugin {
    api_key: String,
}

#[async_trait]
impl ToolPlugin for WeatherPlugin {
    async fn call_tool(&self, req: CallToolRequest) -> McpResult<CallToolResult> {
        let weather = self.fetch_weather(&req.args["location"]).await?;
        Ok(CallToolResult::json(weather))
    }
}

// Runtime plugin management
let plugin_manager = PluginManager::new();
plugin_manager.hot_reload("weather_plugin.so").await?; // Zero downtime

Architectural Innovations

Zero-Configuration Service Discovery

Automatic capability negotiation and runtime schema introspection eliminates manual configuration:

// Client automatically discovers and adapts to server capabilities
let client = ClientSession::auto_discover("./server").await?;
let schema = client.introspect().await?; // Full runtime capability discovery

Fault-Tolerant by Design

Built-in resilience patterns prevent cascading failures in distributed AI systems:

// Circuit breakers, retries, and health checks work together automatically
let result = client
    .with_fallback(backup_service)
    .call_tool_resilient("analyze", data)
    .await?; // Never fails catastrophically

Plugin Ecosystem Revolution

Hot-swappable plugins with ABI stability across Rust versions:

// Live plugin updates without service interruption
plugin_manager.hot_swap("analyzer_v2.so", "analyzer_v1.so").await?;
// Automatic dependency resolution and health monitoring
