MCP Extensions: Memory, Error Handling, and More

MCP extensions add production-critical capabilities to the core MCP protocol — from persistent memory to structured error handling and rate limiting.

MCP Capability Extensions

MCP extensions add capabilities to the core MCP protocol implementation — enabling memory persistence, structured error handling, and other production-critical behaviors.

Additional Extensions

The following extensions are available in Workato's Enterprise MCP platform:

  • Rate Limiting — controls how frequently an agent can call specific tools, preventing runaway loops and protecting downstream systems
  • Caching — caches tool responses for defined TTLs, reducing latency and system load for frequently-called read tools
  • Streaming — enables streaming responses for long-running tool calls, allowing the agent to begin processing results before the full response is ready
  • Webhooks — allows MCP tools to trigger asynchronous processes and receive callbacks when those processes complete
