What it does

Klanex-MCP is a Model Context Protocol server that provides a robust execution layer for AI agent tool calls. It intercepts and validates tool payloads before execution, preventing hallucinated or malformed requests from running. The server manages failures gracefully with automatic retries, exponential backoff, and circuit breakers to handle rate limits and service outages.

Key Features

• Schema validation to prevent hallucinated payloads
• Automatic retry logic with exponential backoff
• Circuit breaker pattern for cascading failure prevention
• Idempotency key support for safe retries
• Human approval gates for sensitive operations
• Encrypted credential storage and management
• Request replay capability for debugging
• Signed webhook results for integrity verification
• Comprehensive error handling and reporting

How to set up

Install the MCP server from the GitHub repository and configure it with your environment variables for credential encryption. Set up approved tool schemas and configure approval thresholds for sensitive operations. Connect it to your Claude instance or other MCP-compatible clients and define which tools should route through the execution engine.
