## Which one, for what

### PostHog (B)

Good for: An agent that answers product questions in SQL or with funnel, retention and trends queries, and that manages feature flags, experiments and error tracking in the same project.

Ahead on:
- Schema & documentation, 81 against 45
- Agent ergonomics, 78 against 45
- Security & auth, 84 against 22
- Payments & pricing, 40 against 30
- Maintenance & community, 89 against 9
- Transparency & trust, 83 against 61

Also in its favour:
- Free to start without a card
- Open source

Watch for: 31 incidents on the status page between 9 July and 6 October 2026, four of them analytics query timeouts or failures

### Woopra (E)

Good for: An agent that reads a company's existing Woopra reports, looks up or edits customer profiles, or exports raw sessions on a schedule.

Ahead on:
- Reliability, 80 against 74

Also in its favour:
- No incidents deducted, where PostHog loses 7 points for them

Watch for: Report endpoints run a report saved in the web app by `report_id`. No endpoint to define a query, funnel or segment was found in the reference

## Verdicts

**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.

**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.

## Before you call either

### PostHog

1. Add `?readonly=true` or the `x-posthog-read-only` header to the MCP URL unless the task needs writes
2. Pin the session with `x-posthog-project-id`, which also removes the `switch-project` and `switch-organization` tools
3. In CLI mode run `info <tool>` once before `call`, and send one `exec` command per request
4. On a 429 with code `api_queries_budget_exceeded`, wait for `Retry-After` and read `X-PostHog-Query-Budget-Remaining-Bytes`
5. Page SQL results by keyset on `timestamp`. `OFFSET` returns 400 for personal API keys, and results cap at 50,000 rows

### Woopra

1. 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`
2. 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/`
3. 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
4. Reuse the `snapshot` ID from the first response when paging with `offset`, or pages past 1,000 records may not agree
5. 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
6. When reading `/logs/export`, delete the profile named in each `type: "delete"` line. The following lines log its data again under `new_id`
