From your agent

What it is

Register den mcp with your agent once. From then on the agent has den’s tools — runbook_guide, validate_runbook, and, when you allow it, run_runbook — and a prompt, /mcp__den__new_runbook, that hands it the guide and your request. den mcp is a server the agent starts itself: it is registered, not piped into the agent.

Configuration

den.yaml is the CLI demo’s config plus:

Key	Meaning
`mcp.allow_runbooks`	`true`: the agent may also list and run runbooks, so it can run the one it wrote. Writing needs no permission: the guide and the validator only read

Prerequisites

Claude Code (or Codex), logged in, and go for the runbook the demo asks for. No AWS.

Usage

claude mcp add den -- den mcp -c ~/.config/den/den.yaml      # Claude Code
codex mcp add den -- den mcp -c ~/.config/den/den.yaml       # Codex

Then, in the agent: /mcp__den__new_runbook the current UTC time and this env's region, in Go (Claude Code), or the same in plain words. The recording registers den for its folder only and removes it at the end (claude mcp remove den). Re-render: vhs docs/runbooks/agents/mcp/agent-mcp.tape.
