01AUTHENTICATE
Create a PlanStack API key.
Generate a key in settings. It is displayed once and stored only as a secure hash.
PLANSTACK_API_KEY=ps_live_••••••••How it works
From agent output to shared artifact in three moves.
PlanStack is a hosted MCP server. Connect it once, then publish and retrieve plans without leaving your coding workflow.
02CONNECT
Add one MCP endpoint.
Use the same hosted endpoint in Claude Code, Cursor, Codex, Windsurf, or any MCP-compatible client.
https://mcp.planstack.dev/mcp03PUBLISH
Ask your agent to publish.
The agent calls publish_plan and gets a stable URL. Updates create immutable versions behind that same link.
publish_plan → /p/k3f9qm2p · v1The human interface
“Publish this implementation plan and send me the link.”
