Scored 2026-08-31 13:45 across 12 tools

Disambiguation4/5

Most tools map cleanly to a resource-action pair: members, subscriptions, plans, passes, and coupons. The main ambiguity is between list_passes and list_plans, and the two GraphQL escape hatches intentionally overlap with every dedicated tool, though their descriptions make the boundaries fairly clear.

Naming Consistency4/5

Tools follow a predictable snake_case verb_noun pattern: create_, get_, list_, update_, and change_ are used consistently for the curated operations. The exceptions are memberful_graphql and memberful_query, which use a different naming style, and change_subscription_expiration uses 'change' instead of 'update'.

Tool Count5/5

Twelve tools is a well-scoped size for a Memberful integration. The curated tools cover the main resources, and the two escape hatches provide flexible coverage without needing dozens of narrow tools.

Completeness4/5

The curated tools cover member creation/reading/updating, subscription retrieval, coupon creation, and plan/pass listing. However, important lifecycle operations like cancelling or modifying subscriptions, deleting members, and managing plans are only available through the generic memberful_graphql escape hatch rather than dedicated tools.

Available Tools

12 tools

change_subscription_expirationChange subscription expiration

Destructive

Inspect

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).

ParametersJSON Schema

Name	Required	Description	Default
`id`	Yes	The subscription id (required).
`expiresAt`	Yes	New expiration as a Unix timestamp in SECONDS (Int, required).

create_couponsCreate coupons

Destructive

Inspect

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).

ParametersJSON Schema

Name	Required	Description	Default
`codes`	Yes	Coupon code strings to create (at least one, required).
`discountId`	No	The discount id to attach the coupons to.

create_memberCreate a member

Destructive

Inspect

MUTATES Memberful data: create a new member with an email (and optional full name). Memberful GraphQL: memberCreate(email, fullName).

ParametersJSON Schema

Name	Required	Description	Default
`email`	Yes	The new member's email (required).
`fullName`	No	The new member's full name.

get_memberGet a member

Read-only

Inspect

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).

ParametersJSON Schema

Name	Required	Description	Default
`id`	Yes	The member id.

get_subscriptionGet a subscription

Read-only

Inspect

Fetch one subscription by id: status, activated/expires/trial timestamps, plan, member, orders, coupon. Memberful GraphQL: subscription(id).

ParametersJSON Schema

Name	Required	Description	Default
`id`	Yes	The subscription id.

list_membersList members

Read-only

Inspect

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: members connection.

ParametersJSON Schema

Name	Required	Description
`last`	No	Max members to return, from the end.
`after`	No	Cursor for the next page (the `cursor` of the last edge from a prior call).
`first`	No	Max members to return, from the start (page size).
`before`	No	Cursor for the previous page.
`activeOnly`	No	Only return members with an ACTIVE membership state.

list_passesList passes

Read-only

Inspect

List all passes (Memberful dashboard 'Plans' — the access groups a member subscribes to): id, name. Memberful GraphQL: passes.

ParametersJSON Schema

Name	Required	Description	Default
No parameters

list_plansList plans

Read-only

Inspect

List all plans (Memberful dashboard 'Prices'): name, interval, price (cents), for-sale flag, plan group. Memberful GraphQL: plans.

ParametersJSON Schema

Name	Required	Description	Default
No parameters

list_subscriptionsList subscriptions

Read-only

Inspect

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.

ParametersJSON Schema

Name	Required	Description
`last`	No	Max subscriptions to return, from the end.
`after`	No	Cursor for the next page (the `cursor` of the last edge from a prior call).
`first`	No	Max subscriptions to return, from the start (page size).
`before`	No	Cursor for the previous page.

memberful_graphqlRun a GraphQL operation (query or mutation)

Destructive

Inspect

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.

ParametersJSON Schema

Name	Required	Description	Default
`query`	Yes	A GraphQL query or mutation document.
`variables`	No	Variables object for the operation.

memberful_queryRun a GraphQL query (read-only)

Read-only

Inspect

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).

ParametersJSON Schema

Name	Required	Description	Default
`query`	Yes	A GraphQL query document (must be a query, not a mutation).
`variables`	No	Variables object for the query.

update_memberUpdate a member

Destructive

Inspect

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).

ParametersJSON Schema

Name	Required	Description	Default
`id`	Yes	The member id (required).
`metadata`	No	Metadata as a JSON string (max 50 keys, 40-char keys, 500-char values).
