Merge Agent Handler review

Merge Agent Handler brings Merge's integration background to agent tool calling. It offers thousands of pre-built connectors that Merge maintains with detailed error handling, plus built-in authentication that guides a user through connecting a tool when the agent tries to act on an unauthenticated connector. Tool Packs bundle the exact connectors each agent needs, scoped by agent type, customer tier or environment, so agents only see tools they can call. On the security side, every tool call can be scanned for sensitive data, with policies that block, redact or mask it before it reaches a model or third party, and audit logs are on all plans. Agent Handler is built on MCP, so it works with Claude, Cursor, ChatGPT or any framework. Merge says it is free to start and priced by monthly credits consumed by tool calls, but the public pricing page did not show Agent Handler figures when we checked, so cost is hard to compare.
