MemberPress

MemberPress is a WordPress membership, course and subscription-commerce plugin built by Caseproof. It turns a self-hosted WordPress site into a paid membership business — content protection through Smart Rules, memberships and groups as products, coupons, transactions, recurring subscriptions across Stripe, PayPal, Square and Authorize.net, courses and quizzes, ClubSuite communities and CoachKit coaching. Its developer surface is the Developer Tools add-on, which exposes a REST API under the WordPress namespace /wp-json/mp/v1 on the site owner's own installation, plus a webhook subscription surface for fourteen membership and billing events. The AI Foundation add-on ships a WordPress MCP server that lets Claude, Cursor and VS Code read and act on membership data directly.

MemberPress publishes 1 API on the APIs.io network: Developer Tools REST API. Tagged areas include Company, Membership, Subscriptions, WordPress, and Payments.

The MemberPress catalog on APIs.io includes 1 event-driven AsyncAPI specification.

MemberPress’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

  name: MemberPress Developer Tools REST API
  description: REST API exposed by the MemberPress Developer Tools add-on on the site owner's own WordPress installation,
    under the WordPress REST namespace mp/v1. Covers members, memberships, transactions, subscriptions, groups, rules, coupons,
    reminders and the event log, plus webhook subscribe/unsubscribe. Authenticated with a Developer Tools API key sent in
    the MEMBERPRESS-API-KEY header (the documentation repository and Postman collection send the same key in the Authorization
    header), or as a logged-in WordPress user holding the remove_users capability. MemberPress is self-hosted, so the base
    URL is always the customer's own site.

    note: MemberPress publishes no OpenAPI. The openapi/ file is an API Evangelist derivation of MemberPress's own README,
      Postman collection and Developer Tools documentation; the Postman collection under postman/ is the provider-published
      artifact, saved verbatim.
    endpoints_checked: MemberPress is self-hosted — there is no vendor-operated host to call anonymously, so no live endpoint
      probe is possible without a customer installation.

  description: WordPress MCP server shipped by the MemberPress AI Foundation add-on. It exposes membership, subscription,
    transaction, coupon, access-rule and reporting tools — MemberPress states 41 tools on a standard install, with more added
    by the Courses, Corporate Accounts, Downloads and Gifting add-ons — to MCP clients such as Claude Desktop, Claude Code,
    Cursor, VS Code and Windsurf. The server runs inside the customer's own WordPress site, so there is no vendor-hosted remote
    MCP endpoint to introspect anonymously.
