# 🦀 RustChain Community MCP Server Guide

## Overview

The RustChain Community MCP (Model Context Protocol) Server provides high-performance AI agent workflow execution with enterprise-grade security and compliance. Built in Rust for memory safety and blazing performance, it delivers 10-100x speed improvements over Python alternatives while maintaining full MCP compatibility.

## 🎯 Quick Start

### 1. Install RustChain

```bash
# Install from Cargo
cargo install rustchain-community

# Or build from source
git clone https://github.com/Michael-A-Kuykendall/rustchain-community.git
cd rustchain-community
cargo build --release --features="cli,llm,tools,rag"
```

### 2. Start the MCP Server

```bash
# Start integrated MCP server (default port 8080)
rustchain server start --mcp-port 8080

# Start with custom configuration
rustchain server start --config rustchain.toml --mcp-port 3000

# Development mode with hot reload
rustchain server dev --mcp-enabled
```

### 3. Verify Server Health

```bash
# Health check endpoint
curl http://localhost:8080/health

# Expected response:
{
  "status": "healthy",
  "server": "RustChain Community MCP",
  "version": "0.1.0",
  "endpoints": ["/mcp", "/health", "/missions", "/tools"],
  "features": ["agent", "chain", "llm", "rag", "compliance"]
}
```

### 4. Test MCP Communication

```bash
# Basic ping test (JSON-RPC 2.0)
curl -X POST http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"ping","id":1}'

# Expected response:
{
  "jsonrpc": "2.0",
  "result": {
    "status": "pong",
    "server": "RustChain Community MCP",
    "version": "0.1.0",
    "performance": {
      "avg_response_time_ms": 0.8,
      "memory_usage_mb": 2.3
    }
  },
  "id": 1
}
```

## 🔧 Server Configuration

### Basic Configuration (rustchain.toml)

```toml
[server]
host = "0.0.0.0"
port = 8080
mcp_enabled = true
max_connections = 1000

[security]
enable_audit = true
compliance_mode = "enterprise"
policy_enforcement = true

[performance]
worker_threads = 8
max_memory_mb = 512
request_timeout_ms = 30000

[features]
llm_providers = ["openai", "anthropic", "ollama"]
vector_stores = ["qdrant", "pinecone"]
tool_sandboxing = true
```

### MCP-Specific Settings

```toml
[mcp]
port = 8080
max_request_size_mb = 10
enable_streaming = true
cors_enabled = true
rate_limit_requests_per_minute = 1000

[mcp.methods]
# Core MCP methods
ping = true
tools_list = true
tools_call = true
resources_list = true

```

## 🛡️ Enterprise Security Features

### Memory-Safe Architecture

RustChain's Rust foundation provides:
- **Zero Buffer Overflows**: Compile-time memory safety
- **No Use-After-Free**: Ownership model prevents dangling pointers
- **Thread Safety**: Fearless concurrency without data races
- **Resource Management**: Automatic cleanup prevents memory leaks

### Policy Enforcement

```bash
# Create security policy
cat > security-policy.yaml << EOF
version: "1.0"
name: "enterprise_security_policy"
rules:
  - action: "file_access"
    allow_paths: ["/workspace", "/tmp"]
    deny_patterns: ["*.env", "*.key", "*/secrets/*"]
  - action: "network_access"
    allow_domains: ["api.openai.com", "*.anthropic.com"]
    deny_protocols: ["ftp", "telnet"]
  - action: "command_execution"
    allow_commands: ["git", "npm", "cargo"]
    sandbox_mode: true
EOF

# Apply policy
rustchain policy apply security-policy.yaml
```

### Audit Trail System

```bash
# Enable comprehensive auditing
rustchain audit configure \
  --format json \
  --output /var/log/rustchain/audit.log \
  --include-requests \
  --include-responses \
  --compliance-mode sox

# Query audit logs
rustchain audit query \
  --from "2024-01-01" \
  --to "2024-01-31" \
  --user-id "enterprise-user" \
  --output audit-report.json
```

      jsonrpc: '2.0',
      method: 'mission/execute',
      params: { mission_yaml: missionYaml, variables },
      id: ++this.requestId
    };
    
    return this.sendRequest(request);
  }

  async callTool(name, arguments) {
    const request = {
      jsonrpc: '2.0',
      method: 'tools/call',
      params: { name, arguments },
      id: ++this.requestId

## 🔍 Troubleshooting

### Server Won't Start

```bash
# Check if port is in use
netstat -tulpn | grep 8080

# Check configuration
rustchain config validate

# Start with verbose logging
RUST_LOG=debug rustchain server start
```

### Performance Issues

```bash
# Check system resources
rustchain diagnostics system

# Monitor memory usage
rustchain diagnostics memory --watch

# Profile performance

```

### Connection Issues

```bash
# Test local connectivity
curl -f http://localhost:8080/health

# Check firewall settings
sudo ufw status

# Verify MCP endpoint
curl -X POST http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"ping","id":1}' \
  -v
```
