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**GrowthBook.** GrowthBook Cloud's MCP server has four tools with read and write annotations, OAuth with dynamic client registration, and a 414-operation OpenAPI spec behind it. The free plan needs no card. The API tools pass paths and JSON bodies through without validation, every key is limited to 60 requests a minute, and audit logs are Enterprise only.\n\n## Before you call either\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### GrowthBook\n\n1. Connect to https://mcp.growthbook.io/mcp and complete OAuth in a browser. Use https://mcp.growthbook.io/mcp/api for the two API tools alone\n2. Call `growthbook_list_skills` and `growthbook_read_skill` before writing. The API tools don't validate payloads, so use the paths the skill names\n3. Stay under 60 requests a minute per key. On 429 wait for the `RateLimit-Reset` seconds before retrying\n4. List calls return 10 items by default. Pass `limit` up to 100 and `offset` to page\n5. A 422 is a soft warning. Resubmit with `?ignoreWarnings=true` only after reading the message\n\n## Questions\n\n### Which is better for AI agents, Countly or GrowthBook?\n\nGrowthBook scores 70.1 (BB) on agent readiness against Countly's 54.8 (C), and leads in every scored category.\n\n### Do Countly and GrowthBook need an API key?\n\nCountly needs an API key. GrowthBook takes an API key or an OAuth sign-in.\n\n### Can an agent call Countly and GrowthBook without installing anything?\n\nYes. Countly has a hosted endpoint at https://mcp.count.ly/mcp and GrowthBook at https://mcp.growthbook.io/mcp.\n\n### Are Countly and GrowthBook open source?\n\nYes. 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). GrowthBook is open source (MIT for the core and for the MCP server. Three enterprise directories in the main repository are under GrowthBook's enterprise licence. GrowthBook Cloud is a hosted service under the Customer Agreement).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/countly-vs-growthbook.json, and with the fewest tokens: https://www.anchorterminal.com/compare/countly-vs-growthbook.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"countly\", \"b\": \"growthbook\"}`.
