Cohesor is an AI gateway and control plane for agent traffic. It sits between agents and model providers to route requests, compress tokens, broker MCP tool calls, and enforce policy before requests reach a model or external tool.
The product is aimed at teams running AI agents that want one endpoint for multiple models and tools, plus controls for spend and visibility. The site describes Anthropic and OpenAI protocol compatibility, support for common agent clients, and a usage-based pricing model built around a per-request platform fee plus provider-cost LLM usage.
