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**Woopra.** Woopra's REST API returns saved Trends, Journeys, Retention and Attribution reports, profiles and raw session logs, with published limits of 300 calls a minute and 3,000 a day per project. A report must first be built in the web app, the tracking endpoints accept events without a secret by default, and no changelog or SLA was found.\n\n## Before you call either\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### Woopra\n\n1. Ask the owner to build and save each report in the web app first, then pass the last path segment of its URL as `report_id`\n2. Authenticate REST calls with HTTP Basic, using the App ID and Secret Key from the Access Keys tab, against `https://www.woopra.com/rest/3.10/`\n3. Stay under 300 calls a minute, 600 an hour and 3,000 a day per project. A 429 carries no documented retry interval, so back off on your own schedule\n4. Reuse the `snapshot` ID from the first response when paging with `offset`, or pages past 1,000 records may not agree\n5. Send `cookie` or a `cv_` identifier such as `cv_email` on every track call. Without one the event lands on a random profile that can't be identified later\n6. When reading `/logs/export`, delete the profile named in each `type: \"delete\"` line. The following lines log its data again under `new_id`\n\n## Questions\n\n### Which is better for AI agents, PostHog or Woopra?\n\nPostHog scores 68.4 (B) on agent readiness against Woopra's 44.4 (E), and leads in 6 of 7 scored categories. Woopra leads on reliability.\n\n### Do PostHog and Woopra need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call PostHog and Woopra without installing anything?\n\nYes. PostHog has a hosted endpoint at https://us.posthog.com and Woopra at https://www.woopra.com/rest/3.10.\n\n### Are PostHog and Woopra open source?\n\nPostHog 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). No open-source release is listed for Woopra.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/posthog-vs-woopra.json, and with the fewest tokens: https://www.anchorterminal.com/compare/posthog-vs-woopra.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"posthog\", \"b\": \"woopra\"}`.
