Overview

API requests to the Merge Agent Handler MCP endpoint are rate limited to 30 requests per minute per registered user. 
https://ah-api.merge.dev/api/v1/tool-packs/<tool-pack-id>/registered-users/<registered-user-id>/mcp
When the rate limit is exceeded, the API returns a 429 Too Many Requests response. The limit resets on a rolling one-minute window.

​
Best practices

  • Implement exponential backoff when you receive a 429 response.
  • Design your integration to stay within the 30 requests/minute limit per registered user.
