No rate limit figures are published, Pro starts at $1,000 a month with no published overage rate, and failed or blocked calls spend credits.\n\n**Zapier MCP (agent actions).** 16 meta-tools in agentic mode, or managed mode with only the actions you pick. Connection tokens are long-lived and the docs allow them in the URL query string.\n\n## Before you call either\n\n### Merge Agent Handler\n\n1. Call `search_tools` with a plain-language intent before `tools/list`. A Tool Pack can hold hundreds of tools and Slack alone lists 50\n2. Add `?connectors=slack` to the MCP URL to limit a connection to named connectors, and `?paginated=true` only if the client follows `nextCursor`\n3. Carry a user-scoped key with `runtime:all` only. The production key reaches every Registered User and the management endpoints\n4. On `reauth_required` read `data.reauth_reason`, then call `authenticate_\u003cconnector\u003e` by name. Intent search doesn't return the authenticate tools\n5. Pin `MCP-Protocol-Version` to `2025-03-26` when context is tight. Later revisions repeat object results in `structuredContent`\n\n### Zapier MCP (agent actions)\n\n1. Call discover_zapier_actions and enable_zapier_action before executing, discovery is free and execution costs two tasks\n2. Use execute_zapier_read_action for lookups, keep execute_zapier_write_action for changes\n3. Send the connection token in the `Authorization` header, never in the URL\n4. Count batch writes per item before starting, five rows is ten tasks\n\n## Questions\n\n### Which is better for AI agents, Merge Agent Handler or Zapier MCP (agent actions)?\n\nMerge Agent Handler scores 69.5 (B) on agent readiness against Zapier MCP (agent actions)'s 58.1 (C), and leads in 5 of 7 scored categories. Zapier MCP (agent actions) leads on maintenance \u0026 community.\n\n### Do Merge Agent Handler and Zapier MCP (agent actions) need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Merge Agent Handler and Zapier MCP (agent actions) without installing anything?\n\nYes. Merge Agent Handler has a hosted endpoint at https://ah-api.merge.dev/mcp and Zapier MCP (agent actions) at https://mcp.zapier.com/api/v1/connect.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/merge-agent-handler-vs-zapier-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/merge-agent-handler-vs-zapier-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"merge-agent-handler\", \"b\": \"zapier-mcp\"}`.
