Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Manage Memberful members, subscriptions, plans, passes and coupons via the GraphQL API.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

claude mcp add --transport http memberful https://memberful.usefulapi.io/mcpPaste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

ChatGPT connects only to servers on the internet:

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
memberful_get_memberFetch one Memberful member by id: profile, Stripe customer id, unrestricted-access flag, total spend, metadata, address, and their subscriptions (each with plan). Memberful GraphQL: member(id).
memberful_list_membersList members (Relay connection): each edge has a cursor + node (profile, Stripe customer id, unrestricted-access flag, total spend, and their subscriptions). Paginate with `first` + `after` (pass the last edge's `cursor`); `first` defaults to 50. Set `activeOnly` to return only m
memberful_get_subscriptionFetch one subscription by id: status, activated/expires/trial timestamps, plan, member, orders, coupon. Memberful GraphQL: subscription(id).
memberful_list_subscriptionsList subscriptions (Relay connection): each edge has a cursor + node (status, expires/created timestamps, plan, member). Paginate with `first` + `after` (pass the last edge's `cursor`); `first` defaults to 50. NOTE: this uses the top-level `subscriptions` connection, which is sou
memberful_list_plansList all plans (Memberful dashboard 'Prices'): name, interval, price (cents), for-sale flag, plan group. Memberful GraphQL: plans.
memberful_list_passesList all passes (Memberful dashboard 'Plans' — the access groups a member subscribes to): id, name. Memberful GraphQL: passes.
memberful_queryEscape hatch: run an arbitrary Memberful GraphQL QUERY (read-only) against your account's /api/graphql endpoint with optional variables. Mutations are REJECTED — use the dedicated write tools or memberful_graphql for those. Useful for fields not covered by the curated read tools
memberful_create_memberMUTATES Memberful data: create a new member with an email (and optional full name). Memberful GraphQL: memberCreate(email, fullName).
memberful_update_memberMUTATES Memberful data: update a member's metadata (a JSON string; max 50 keys, 40-char keys, 500-char values). Only metadata is supported here; for other inline member fields use memberful_graphql. Memberful GraphQL: memberUpdate(id, metadata).
memberful_change_subscription_expirationMUTATES Memberful data: change WHEN a subscription expires (extend or shorten access). expiresAt is a Unix timestamp in SECONDS (Int). Memberful GraphQL: subscriptionChangeExpirationTime(id, expiresAt).
memberful_create_couponsMUTATES Memberful data: create one or more coupon codes for a discount. Provide the discount id (discountId) and the coupon code strings. Memberful GraphQL: createCoupons(discountId, coupons).
memberful_graphqlMUTATES Memberful data (potentially): escape hatch to run an arbitrary Memberful GraphQL operation — including any mutation — against your account's /api/graphql endpoint with optional variables. Prefer memberful_query for read-only calls.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.36.3) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Manage your Memberful memberships from Claude, Cursor, or any MCP client — read and manage members, subscriptions, plans, passes and coupons over the Memberful GraphQL API.
Live endpoint: https://memberful.usefulapi.io/mcp · Homepage: https://usefulapi.io/memberful
https://memberful.usefulapi.io/mcp.claude mcp add --transport http memberful https://memberful.usefulapi.io/mcp, then run /mcp to log in.{

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Memberful credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/memberful/
On first connect you'll paste your Memberful API key — create one in the Memberful dashboard under Settings → Custom applications. It's sent as a Bearer token to your account's GraphQL endpoint.

| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with memberful_upgrade (it returns a Stripe Checkout link). Cancel any time with memberful_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running memberful_upgrade before then undoes the cancel. Or write to support@usefulapi.io.
