What this MCP does

Manages account signup, subscription checkout and status, and OAuth connection for access to a federal and state legislative research service.

connect_congressmcp_account
Connect a CongressMCP account with OAuth
Use this after subscription activation when the user wants this chat to access CongressMCP. It returns the MCP OAuth challenge so the host can open CongressMCP’s authorization and consent flow. Never ask the user to paste a password, API key, access token, or refresh token into chat.

create_subscription_checkout
Create a CongressMCP Stripe Checkout
Use this only after email verification, a plan selection from list_subscription_plans, and explicit user confirmation. It creates an idempotent Stripe-hosted subscription Checkout tied to the verified account and returns the external checkout URL. Stripe collects card details outside chat, and creating the URL does not itself complete the purchase.

get_subscription_status
Get CongressMCP subscription status
Use this after checkout to check whether Stripe’s signed webhook has activated the verified account. It reads the current server-side entitlement and never retries payment or changes billing. When paid is true, use connect_congressmcp_account to authorize this chat.

list_subscription_plans
List CongressMCP subscription plans
Use this before checkout to show the current CongressMCP plans and exact server-configured prices. Amounts are integer minor currency units, such as cents, and listing plans never starts a checkout or charge. Do not guess a price or use a plan identifier that is not returned here.

start_email_signup
Send a CongressMCP email verification code
Use this when the user wants to create or recover a CongressMCP account in chat. It sends a six-digit, 15-minute code to the supplied email after explicit acceptance of the terms and privacy policy. It does not start a subscription, expose whether an account already exists, or charge anything.

verify_email_signup
Verify a CongressMCP email code
Use this after start_email_signup when the user provides the six-digit code from their email. It verifies email control, activates the free account when needed, and returns a short-lived onboarding token for checkout and status calls. The token is not an OAuth token or API key and cannot access CongressMCP research or workspace data.
