@assemblyline-agents/arcads

Official Assembly Line connection plugin for the Arcads hosted Streamable HTTP MCP server at https://mcp.arcads.ai.

Setup

Arcads uses OAuth 2.0 Authorization Code + PKCE and dynamic client registration. Register one client for the Assembly Line deployment:

curl -X POST https://api.arcads.ai/oauth/register \
  -H 'content-type: application/json' \
  -d '{
    "client_name": "Assembly Line",
    "redirect_uris": ["https://YOUR-AGENT-HOST/assembly-line/connections/callback"],
    "grant_types": ["authorization_code", "refresh_token"],
    "response_types": ["code"],
    "token_endpoint_auth_method": "none"
  }'

Store the returned client_id as ARCADS_MCP_CLIENT_ID. Set ARCADS_MCP_REDIRECT_URI only when the registered callback differs from Assembly Line's normal connection callback URL.

assembly-line add arcads agent

The selected plugin enables its reviewed Arcads tools. Change authority only through plugins.arcads.connections.arcads.approval or disable in agent.md; use the provider action names shown by assembly-line capabilities agent.

The deployment owner supplies the Arcads account, subscription, OAuth client, credit policy, and callback URL. OAuth tokens stay in Assembly Line's connection grant store.
