Memberstack is a platform that enables developers to add user authentication, payments, and member management to their websites without writing backend code.
Memberstack is a platform that enables developers to add user authentication, payments, and member management to their websites without writing backend code. On Nagent, Memberstack is exposed as a fully-configurable security & identity tools integration that any agent can call — 8 actions, and API key authentication. No code is required to wire Memberstack into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Memberstack to automate the kinds of tasks security & identity tools teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Memberstack into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Memberstack, with input parameters and output schema. Drop these into any step of an agent built in Helix.
MEMBERSTACK_CREATE_MEMBERTool to create a new member in your application. Use after gathering email, password, optional plans, custom fields, metadata, and redirect.
Input parameters
Arbitrary JSON data for the member (replaces existing JSON).
The member's unique email address
Array of free plan objects to assign to the member on creation.
Metadata for the member (replaces existing metadata).
The member's password
Custom fields for the member (replaces existing fields).
URL path to redirect to after login
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_DELETE_MEMBERTool to permanently delete a member from your application. Use after confirming you no longer need the member's data and have the member ID.
Input parameters
The ID of the member to delete.
Whether to delete the associated Stripe customer. Defaults to false.
Whether to cancel the associated Stripe subscriptions. Defaults to false.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_GET_MEMBERTool to retrieve a specific member by ID or email. Use when you need to fetch member profile details for a given identifier (ID or email). Example: "Get member mem_sb_12345".
Input parameters
The member's ID (starting with 'mem_') or email address (raw, unencoded).
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_LIST_DATA_TABLESTool to retrieve all data tables in your Memberstack application. Returns table metadata including keys, field definitions, and access control rules.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_LIST_MEMBERSTool to retrieve a paginated list of all members in your application. Use when you need to iterate through members with cursor-based pagination.
Input parameters
The endCursor after which to start listing members
Maximum number of members to return (max 200)
Sort order for members (ASC or DESC)
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_LIST_PLANSTool to list all available membership plans. Use when you need to retrieve plan IDs and details before assigning or comparing plans.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_REMOVE_FREE_PLANTool to remove a free plan from an existing member. Use after confirming the member's subscription status. Example: "Remove free plan pln_sb_67890 from member mem_sb_12345".
Input parameters
Member ID (starts with 'mem_').
Free plan ID (starts with 'pln_').
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
MEMBERSTACK_UPDATE_MEMBERTool to update an existing member's information. Use when you have a member ID and need to modify their email, customFields, metaData, JSON data, or loginRedirect.
Input parameters
Member ID (starts with 'mem_')
Arbitrary JSON object to replace existing data
New email address for the member
Object of metadata to replace existing ones
Object of custom fields to replace existing ones
URL path to redirect to after login
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 66 agents privately built on Nagent that already use Memberstack.
Build on Nagent
Connect Memberstack to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Memberstack, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Memberstack is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Memberstack is connected, you configure its 8 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Memberstack steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Memberstack event fires, the agent kicks off automatically.
Every Memberstack action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Memberstack ships with 8 pre-built security & identity tools actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Memberstack together with other connected tools.
