Stateless MCP and the End of Custom Session Workarounds for Long-Running Agents
Stateless MCP simplifies session management for long-running agents. The new approach reduces the impact of server failures.
The MCP session model is designed for short-lived tool invocations. A stateless approach is necessary to address issues with long-running agents. Currently, when a session closes, the client must start a new session, leading to agent crashes due to server failures and complicating horizontal scaling. The new design ensures each request contains the necessary data, eliminating the need for maintaining session states.
