This page is the agent-readable protocol for Deck integrations. Humans can follow along. Coding agents should treat the protocol section as the source of truth and probe Deck MCP before sending anyone to signup.

Deck integrations — agent protocol

Work MCP-first. Probe Deck MCP in this session before you send anyone to signup.

1. Probe MCP

Call a cheap Deck MCP tool (get_user_context or get_overview). This must be a real tool call.

401 Unauthorized

The human is not connected in this client. Tell them to Connect MCP here (Cursor, Claude, or ChatGPT). Do not open signup. Do not mint or ask for a dk_ API key.

No Deck tools available

Deck MCP is not installed. Fetch and follow the AI PM protocol at:

https://docs.getdeck.io/docs/agents/prompts/ai-pm.md

Do not invent another setup URL. Do not send them to signup from this prompt.

After they return, probe MCP again. If tools exist, continue below.

2. After MCP works

Use list_sources to see connected sources. The MCP resource deck://integrations is allowed if already registered. Do not invent a Slack-connect tool.
