## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-29.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 82/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 661 tokens (~110/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `list_subscription_plans` (~67 tokens)

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` (~135 tokens)

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.

Input parameters:

- `accepted_terms` (boolean, required): True only after the user explicitly accepts https://www.congressmcp.com/terms and https://www.congressmcp.com/privacy.
- `email` (string, required): Email address that will own the CongressMCP account.
- `name` (string, required): Person or organization name for the account.

### `verify_email_signup` (~107 tokens)

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.

Input parameters:

- `code` (string, required): Six-digit code from the CongressMCP verification email.
- `email` (string, required): The same normalized account email used to request the code.

### `create_subscription_checkout` (~151 tokens)

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.

Input parameters:

- `confirm` (boolean, required): True only after the user explicitly confirms creation of checkout for this exact plan and displayed price.
- `idempotency_key` (string, required): Fresh UUID for this checkout; reuse only for the identical retry.
- `onboarding_token` (string, required): Short-lived onboarding token returned by verify_email_signup.
- `plan_id` (string, required): Exact plan identifier returned by list_subscription_plans.

### `get_subscription_status` (~75 tokens)

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.

Input parameters:

- `onboarding_token` (string, required): Short-lived onboarding token returned by verify_email_signup.

### `connect_congressmcp_account` (~70 tokens)

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.
