Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security78

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability77

AI-judged instruction clarity (excellent).Pass
Tool/resource definitions use about 1081 tokens (~90/item across 12 items; 12 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management23

Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass

Capabilities60

Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

MCP tools — 12 exposed · ~1,081 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

change_subscription_expiration Change subscription expiration ~86

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).

Input Output Examples

Name	Type	Req	Description
codes	array	yes	Coupon code strings to create (at least one, required).
discountId	string	—	The discount id to attach the coupons to.

No output schema declared.

No examples provided.

create_member Create a member ~67

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

Input Output Examples

Name	Type	Req	Description
email	string	yes	The new member's email (required).
fullName	string	—	The new member's full name.

No output schema declared.

No examples provided.

get_member Get a member ~59

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).

Input Output Examples

Name	Type	Req	Description
id	string	yes	The member id.

No output schema declared.

No examples provided.

get_subscription Get a subscription ~49

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

Input Output Examples

Name	Type	Req	Description
id	string	yes	The subscription id.

No output schema declared.

No examples provided.

list_members List members ~188

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.

Input Output Examples

Name	Type	Req	Description
activeOnly	boolean	—	Only return members with an ACTIVE membership state.
after	string	—	Cursor for the next page (the `cursor` of the last edge from a prior call).
before	string	—	Cursor for the previous page.
first	integer	—	Max members to return, from the start (page size).
last	integer	—	Max members to return, from the end.

No output schema declared.

No examples provided.

list_passes List passes ~40

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

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_plans List plans ~42

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

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_subscriptions List subscriptions ~166

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.

Input Output Examples

Name	Type	Req	Description
after	string	—	Cursor for the next page (the `cursor` of the last edge from a prior call).
before	string	—	Cursor for the previous page.
first	integer	—	Max subscriptions to return, from the start (page size).
last	integer	—	Max subscriptions to return, from the end.

No output schema declared.

No examples provided.

memberful_graphql Run a GraphQL operation (query or mutation) ~82

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.

Input Output Examples

Name	Type	Req	Description
query	string	yes	A GraphQL query or mutation document.
variables	object	—	Variables object for the operation.

No output schema declared.

No examples provided.

memberful_query Run a GraphQL query (read-only) ~109

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).

Input Output Examples

Name	Type	Req	Description
query	string	yes	A GraphQL query document (must be a query, not a mutation).
variables	object	—	Variables object for the query.

No output schema declared.

No examples provided.

update_member Update a member ~106

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).

Input Output Examples

Name	Type	Req	Description
id	string	yes	The member id (required).
metadata	string	—	Metadata as a JSON string (max 50 keys, 40-char keys, 500-char values).
