Nothing to run from here
Memberful is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Manage Memberful members, subscriptions, plans, passes and coupons via the GraphQL API.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http memberful-mcp https://memberful.usefulapi.io/mcp
# 2 — ask your agent for something these tools do
# get_member, list_members, get_subscription and 9 more
Memberful costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http memberful-mcp https://memberful.usefulapi.io/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
12 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Fetch 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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The member id. |
List 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 members with an ACTIVE membership state. For member-state filters beyond active, use memberful_query. Memberful GraphQL:
| Parameter | Type | Required | Notes |
|---|---|---|---|
| first | integer | no | Max members to return, from the start (page size). |
| after | string | no | Cursor for the next page (the cursor of the last edge from a prior call). |
| last | integer | no | Max members to return, from the end. |
| before | string | no | Cursor for the previous page. |
| activeOnly | boolean | no | Only return members with an ACTIVE membership state. |
Fetch one subscription by id: status, activated/expires/trial timestamps, plan, member, orders, coupon. Memberful GraphQL: subscription(id).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The subscription id. |
List 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 sourced from the community SDK — validate against a live account. Memberful GraphQL: subscriptions connection.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| first | integer | no | Max subscriptions to return, from the start (page size). |
| after | string | no | Cursor for the next page (the cursor of the last edge from a prior call). |
| last | integer | no | Max subscriptions to return, from the end. |
| before | string | no | Cursor for the previous page. |
List all plans (Memberful dashboard 'Prices'): name, interval, price (cents), for-sale flag, plan group. Memberful GraphQL: plans.
No parameter schema on file.
List all passes (Memberful dashboard 'Plans' — the access groups a member subscribes to): id, name. Memberful GraphQL: passes.
No parameter schema on file.
Escape 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 (e.g. member-state filters beyond active).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | yes | A GraphQL query document (must be a query, not a mutation). |
| variables | object | no | Variables object for the query. |
MUTATES Memberful data: create a new member with an email (and optional full name). Memberful GraphQL: memberCreate(email, fullName).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| string | yes | The new member's email (required). | |
| fullName | string | no | The new member's full name. |
MUTATES 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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The member id (required). |
| metadata | string | no | Metadata as a JSON string (max 50 keys, 40-char keys, 500-char values). |
MUTATES Memberful data: change WHEN a subscription expires (extend or shorten access). expiresAt is a Unix timestamp in SECONDS (Int). Memberful GraphQL: subscriptionChangeExpirationTime(id, expiresAt).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| id | string | yes | The subscription id (required). |
| expiresAt | integer | yes | New expiration as a Unix timestamp in SECONDS (Int, required). |
MUTATES 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).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| codes | array | yes | Coupon code strings to create (at least one, required). |
| discountId | string | no | The discount id to attach the coupons to. |
MUTATES 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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | yes | A GraphQL query or mutation document. |
| variables | object | no | Variables object for the operation. |

ATool-list grade · score 93 / 100
Release 1.11.1 · scanned 20 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Memberful can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
