  description: >-
    Scoped Shelter API key, created and revoked at https://shelter.money/developer. Keys are
    read-only by default, prefixed wv_, stored by Shelter as SHA-256 hashes at rest, and shown
    only once at creation (only the prefix displays afterward). In the official MCP server the
    key is supplied via the SHELTER_API_KEY environment variable and sent as the X-Shelter-Key
    request header (per the published client source, src/client.ts).
notes:
- No OAuth flows, OpenID Connect, or mutual TLS are documented; API keys are the only scheme.
- End-user identity comes solely from the scoped key; the MCP package holds no Plaid tokens or
  bank credentials.
- Without a key the official MCP server fails closed — tool definitions load but every response
  is suppressed with reasonCodes [MISSING_SHELTER_API_KEY] and no financial values.
