Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 360 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name memberful-mcp.

  • Pass
    Lists tools

    tools/list returned 12 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 360 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 360 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured

Capabilities

Tools 12

memberful_change_subscription_expiration

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).

Discovered
memberful_create_coupons

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).

Discovered
memberful_create_member

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

Discovered
memberful_get_member

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).

Discovered
memberful_get_subscription

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

Discovered
memberful_graphql

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.

Discovered
memberful_list_members

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.

Discovered
memberful_list_passes

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

Discovered
memberful_list_plans

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

Discovered
memberful_list_subscriptions

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.

Discovered
memberful_query

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).

Discovered
memberful_update_member

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).
