### Description (declared)

# tailscale-blade-mcp

An MCP server that gives AI agents structured access to Tailscale tailnets. Built for the [Model Context Protocol](https://modelcontextprotocol.io) with security visibility and token efficiency as first-class design goals.

## Why this exists

Tailscale exposes a clean REST API (v2) for managing devices, ACL policies, DNS, auth keys, users, and audit logs. This MCP wraps it with the guardrails that automated agents need:

- **Security-first tool set** — 19 tools focused on what network security agents actually need: device inventory, key expiry auditing, ACL review + apply, route approval, DNS hygiene. Not a thin wrapper around every endpoint.
- **Token-efficient output** — compact pipe-delimited format. A 20-device tailnet in ~40 tokens per device. Devices flagged with `KEY_EXPIRY_OFF`, `KEY_EXPIRED`, `UPDATE_AVAILABLE`, `UNAUTHORIZED`, `OFFLINE` at a glance.
- **Write-gated mutations** — device authorization, tagging, key management, route approval, and ACL apply require explicit opt-in via `TAILSCALE_WRITE_ENABLED=true`. Destructive operations (delete device, revoke key) additionally require per-call `confirm=true`; ACL apply defaults to optimistic-concurrency (`If-Match`) so it won't silently clobber a concurrent edit.
- **SecOps visibility** — ACL policy summary shows groups, rules, SSH rules, and tag owners. Audit log shows who changed what. Key listing flags reusable keys and expiry status.
