Verdicts

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.

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

GrowthBook

  1. 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
  2. Call growthbook_list_skills and growthbook_read_skill before writing. The API tools don't validate payloads, so use the paths the skill names
  3. Stay under 60 requests a minute per key. On 429 wait for the RateLimit-Reset seconds before retrying
  4. List calls return 10 items by default. Pass limit up to 100 and offset to page
  5. A 422 is a soft warning. Resubmit with ?ignoreWarnings=true only after reading the message

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
