No MCP rate limits or SLA were found, and status.amplitude.com records a critical outage of the UI, MCP and REST APIs on 13 July 2026.\n\n**Countly.** Countly suits an agent working against a server its owner already runs. The official MCP server filters its 209 tools by edition, plugin and permission and has per-category read-only settings. No status page, OpenAPI document or published API rate limit was found, and the Flex trial needs a credit card.\n\n## Before you call either\n\n### Amplitude\n\n1. Connect to https://mcp.amplitude.com/mcp, or https://mcp.eu.amplitude.com/mcp for EU projects. The client must support streaming HTTP and OAuth, since API keys aren't accepted\n2. Append `?discovery=progressive` to load tool schemas on demand, then call `get_amplitude_context` first to pick the project and read its AI context\n3. Ask an admin for a role with only Use MCP (read) on the projects you need. Tools stay listed and fail at call time when the role lacks the action\n4. Send events through the HTTP V2 API with an `insert_id` on each one. On 429, pause that user or device for 30 seconds before retrying\n5. Budget Dashboard REST queries by cost (days times conditions times chart cost), within 108,000 an hour and 5 concurrent requests per project\n\n### Countly\n\n1. Create a dedicated token in the Token Manager, limited to the apps and endpoints the task needs, and send it in the `countly-token` header, not the URL\n2. Set `COUNTLY_TOOLS_ALL=R` unless the task needs writes. The token's own permissions still apply and the stricter of the two wins\n3. Call `apps_list` first. Most tools need `app_id` or an exact `app_name`\n4. Check `get_version` for the detected edition before planning funnel, retention or cohort queries, which need Enterprise plugins\n5. Set `ENABLE_ANALYTICS=false` to stop usage reports to stats.count.ly, and prefer the stdio server to mcp.count.ly so the server URL and token stay local\n\n## Questions\n\n### Which is better for AI agents, Amplitude or Countly?\n\nAmplitude scores 66.2 (B) on agent readiness against Countly's 54.8 (C), and leads in 6 of 7 scored categories.\n\n### Do Amplitude and Countly need an API key?\n\nAmplitude takes an API key or an OAuth sign-in. Countly needs an API key.\n\n### Can an agent call Amplitude and Countly without installing anything?\n\nYes. Amplitude has a hosted endpoint at https://mcp.amplitude.com/mcp and Countly at https://mcp.count.ly/mcp.\n\n### Are Amplitude and Countly open source?\n\nNo open-source release is listed for Amplitude. Countly is open source (Countly Lite is AGPL-3.0 with added branding terms under Section 7. Enterprise plugins are proprietary. Flex is a hosted service under Countly's terms. The MCP server is MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/amplitude-vs-countly.json, and with the fewest tokens: https://www.anchorterminal.com/compare/amplitude-vs-countly.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"amplitude\", \"b\": \"countly\"}`.
