feat(mcp): add Mission Control MCP server for agent-native tool access
Zero-dependency MCP server (stdio transport, JSON-RPC 2.0) that wraps
the Mission Control REST API as 35 MCP tools. Agents can add it with:
claude mcp add mission-control -- node scripts/mc-mcp-server.cjs
Tools cover the full agent workflow:
- Agent lifecycle: list, get, heartbeat, wake, diagnostics, attribution
- Memory & Soul: read/write/clear working memory, read/write SOUL,
list/retrieve SOUL templates
- Tasks: CRUD, queue polling, broadcast, comments (list/add)
- Sessions: list, control, continue, transcript
- Connections: list, register
- Tokens & Costs: stats, agent-costs, costs-by-agent
- Skills: list, read content
- Cron: list jobs
- Status: health, dashboard, overview
Auth uses the same profile system as the CLI (~/.mission-control/profiles/)
or MC_URL/MC_API_KEY/MC_COOKIE environment variables.
Also adds `mc` and `mc:mcp` package.json scripts.
