name: Accord authentication
note: >-
  Accord runs two distinct authentication models on two distinct hosts: a workspace-scoped bearer API key for the
  GraphQL Developer API on api2.inaccord.com, and OAuth 2.1 + PKCE for the MCP server on api.inaccord.com. There is
  no OpenAPI to derive securitySchemes from; both models are read from Accord's own published documentation, and the
  OAuth parameters are additionally confirmed against Accord's anonymous /.well-known/ metadata.
schemes:
  - id: api-key-bearer
    type: http
    scheme: bearer
    applies_to: https://api2.inaccord.com/graphql
    header: Authorization
    format: 'Authorization: Bearer YOUR_API_KEY'
    issuance: >-
      Created in the Accord app under Settings → Workspace → API Keys by a workspace admin only. Accord states the key
      is shown once — "Copy immediately after creation".
    scoping: >-
      "A key acts within the workspace it was created in. The same Row-Level Security rules that apply to in-app
      sessions apply to API key requests — a key cannot read or change data its workspace wouldn't otherwise be
      able to."
    rotation: >-
      "To rotate a key without downtime, create the replacement first, switch your client to the new key, then delete
      the old one." Accord exposes createApiKey / deleteApiKey mutations in the GraphQL reference.
    expiry: not documented
    scopes: none — the API key has no scope surface; authorization is row-level security, not scopes
    entitlement: >-
      Requires an Accord license that includes API access. Accord's pricing page lists "API Support" only under the
      Enterprise tier.

    user_flow: >-
      The MCP client opens the default browser to api.inaccord.com/1/mcp/authorize, the user enters their workspace
      slug (e.g. acme for acme.inaccord.com) and completes Google SSO; the client stores the token. Accord states
      "no API keys to manage or rotate".
