Connect Memberful to Claude, ChatGPT and Claude Code
Credentials off one Memberful screen, then an endpoint your client signs into. Nothing to deploy, and nothing to install.
In Memberful open Settings, then Custom applications, and add a new one named PopMCP. Paste its API key here with your site address, the one ending in .memberful.com. PopMCP checks the key with one small read before saving it.

Memberful has no test mode, so a change is real as soon as the AI makes it. Cancelling a renewal keeps the access a member paid for, while deleting a subscription ends it at once and cannot be undone. Tick Memberful on the PopMCP consent screen only for clients that should change data. Teammates start on read-only.

FAQ
Memberful MCP server questions
What teams ask before putting Memberful behind an AI client.
What does PopMCP need to connect Memberful?
Your site address and an API key. In Memberful open Settings, then Custom applications, click Add a new Custom Application, name it PopMCP, leave the OAuth box unticked and create it, then copy the API Key. Use the address ending in .memberful.com even if members see your own domain. PopMCP stores the key encrypted and sends it only to that address.
Does the AI see the difference between a plan and a price?
Yes. The Memberful dashboard says Plan and Price, while its API says pass and plan for the same two things. The tools and their descriptions spell this out, so a plan you name is looked up correctly, and access is decided by the plan members subscribe to, not by the price they pay.
Can the AI cancel a member's subscription?
Yes, on a connection with write access. cancel_subscription_renewal stops billing and keeps access until the paid period ends, with no refund, and resume_subscription_renewal undoes it. delete_subscription ends access at once and cannot be undone, and its description tells the AI to confirm with you first.
Are all of Memberful's operations covered?
Yes. Memberful keeps its API reference inside each signed-in account and publishes no schema file, so PopMCP reads the live schema with your key. list_api_operations shows every query and mutation your site offers, and run_api_query and run_api_mutation run any of them by name. Operations Memberful adds later work without an update.
Is there a test mode?
No. Memberful has no sandbox, and its own API Explorer also works on real data. Every change is real at once, so start on a read-only connection if you want to try things first.
What is not available through the API?
Memberful's API only includes custom fields enabled before July 2021, and dates up to 19 January 2038. Webhooks are set up by hand in Memberful, under Settings, then Webhooks. Member sign-in for your own apps is a separate OAuth feature that this connection does not use.
Do I have to run or host the Memberful MCP server myself?
No. PopMCP hosts it and gives you a Streamable HTTP MCP URL. There is nothing to deploy, no callback URL to register, and no infrastructure to keep running or patch.
Which AI clients can use this MCP server?
Any client that supports a remote Streamable HTTP MCP server: Claude Desktop, Claude Web, Claude Code, ChatGPT custom connectors, Codex and the Codex CLI, OpenCode and Z.ai's ZCode, as well as editors such as Cursor, Windsurf and Zed. Your client signs in to PopMCP with OAuth; the provider credential never leaves the server.
How do I connect Memberful to Claude Code?
Connect Memberful in PopMCP first, then run claude mcp add --transport http popmcp https://app.popmcp.com/mcp in a terminal. Inside Claude Code, run /mcp and sign in to PopMCP in the browser window it opens, ticking Memberful on the consent screen. The Memberful tools are then available in that session, and no Memberful credential is stored on your machine.
Do all 25 Memberful tools load by default?
Yes. The Memberful catalog is small enough that all 25 tool definitions load into every conversation, so your AI never has to search for one before it can call it.
What is the difference between a tool and a trigger?
A tool is something your AI calls, and there are 25 here. A trigger is something PopMCP watches for you: 6 Memberful events that can start work on the PopMCP side. Triggers never enter your AI client's context, and none of them ask you to paste a callback URL into Memberful.
