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**PostHog.** PostHog suits agents that need to query product data and manage flags or experiments. Its hosted MCP server has OAuth scopes, a read-only mode and a one-tool CLI mode over 1,096 tools. The status page shows 31 incidents in 90 days, four on analytics queries, and three security incidents were disclosed in the last year.\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### PostHog\n\n1. Add `?readonly=true` or the `x-posthog-read-only` header to the MCP URL unless the task needs writes\n2. Pin the session with `x-posthog-project-id`, which also removes the `switch-project` and `switch-organization` tools\n3. In CLI mode run `info \u003ctool\u003e` once before `call`, and send one `exec` command per request\n4. On a 429 with code `api_queries_budget_exceeded`, wait for `Retry-After` and read `X-PostHog-Query-Budget-Remaining-Bytes`\n5. Page SQL results by keyset on `timestamp`. `OFFSET` returns 400 for personal API keys, and results cap at 50,000 rows\n\n## Questions\n\n### Which is better for AI agents, Countly or PostHog?\n\nPostHog scores 68.4 (B) on agent readiness against Countly's 54.8 (C), and leads in every scored category.\n\n### Do Countly and PostHog need an API key?\n\nCountly needs an API key. PostHog takes an API key or an OAuth sign-in.\n\n### Can an agent call Countly and PostHog without installing anything?\n\nYes. Countly has a hosted endpoint at https://mcp.count.ly/mcp and PostHog at https://us.posthog.com.\n\n### Are Countly and PostHog 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). PostHog is open source (MIT for the repository outside the `ee` directory, which has its own licence. PostHog Cloud is a hosted service under PostHog's terms).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/countly-vs-posthog.json, and with the fewest tokens: https://www.anchorterminal.com/compare/countly-vs-posthog.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"countly\", \"b\": \"posthog\"}`.
