Model Context Protocol server for **production-safe autonomous development diagnostics**. Provides tools for reading logs, environment state, CORS configuration, network summaries, and live probing with role-based access control.

## Features

- 🔒 **Production-Safe**: Sampling, redaction, and allowlist-based probing
- 🎯 **Role-Based Access Control (RBAC)**: Reader and Operator roles with JWT auth
- 📊 **Metrics Integration**: Prometheus/OTLP adapter for rates and latencies
- 🔍 **Smart Probing**: Allow-listed URL diagnostics with header redaction
- 📈 **Adaptive Sampling**: Configurable rates for dev, staging, and production
- 🛡️ **Security First**: No request/response bodies in prod, sensitive header filtering

## Scope

### Supported Environments

- **Development**: Full logging, no sampling (100%), unrestricted access
- **Staging**: Medium sampling (5-10%), read-only for most users
- **Production**: Minimal sampling (1-5%), strict allowlists, audit logging

### Operating Modes

- `dev` - Full access, no restrictions
- `prod:observe` - Read-only metrics and logs with sampling
- `prod:incident` - Temporary elevated access with TTL auto-revert
