## Which one, for what

### Statsig (BB)

Good for: An agent that creates, updates and cleans up feature gates, dynamic configs and experiments, and reads experiment results and audit history.

Ahead on:
- Schema & documentation, 82 against 45
- Agent ergonomics, 71 against 45
- Security & auth, 74 against 22
- Payments & pricing, 40 against 30
- Maintenance & community, 81 against 9
- Transparency & trust, 75 against 61

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: Console API errors carry only `status` and `message`, and the spec documents no 429 response

### 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.

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

**Statsig.** Statsig suits agents that manage feature gates and experiments and read their results. Its MCP server has 18 default tools, OAuth, read-only access by project and role, and a confirmation on updates. Errors carry only a status and a message, no idempotency keys were found, and the privacy notice is Amplitude's and doesn't name Statsig.

**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

### Statsig

1. Connect to https://api.statsig.com/v3/mcp. The official MCP registry entry still lists the V1 URL, which has 93 tools
2. Call `get_context` first to learn the project, your permissions and the review settings
3. Read the resource before `gate_update`, `experiment_update` or `dynamic_config_update`. They replace the whole resource, so resend every field you want kept
4. Use `discover_tools` for partial edits, and fetch a fresh `operationHandle` when one expires
5. On a 429 slow down and back off with jitter. Rejected attempts count towards the quota of about 1,800 mutations per 15 minutes

### 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`
