ubiquiti-unifi-blade-mcp

An MCP server that gives AI agents structured access to Ubiquiti UniFi network controllers. Built for the Model Context Protocol with security visibility and token efficiency as first-class design goals.

Why this exists

UniFi controllers expose a rich but undocumented REST API behind cookie-based auth with CSRF tokens and optional 2FA. The aiounifi library (MIT, powers the Home Assistant integration) handles the protocol complexity — UniFi OS vs classic controller detection, TOTP 2FA, websocket events. This MCP wraps it with the guardrails that automated agents need:

• Security-first tool set — 18 tools focused on what network security agents actually need: device health, client visibility, firewall state, traffic rules, DPI restrictions, port forwards. Not 161 tools for every possible configuration change.
• Token-efficient output — compact pipe-delimited format. A 30-device network in ~50 tokens per device. Client listings with signal strength, experience score, and blocked status at a glance.
• Write-gated mutations — client blocking, WLAN toggling, device restart, and traffic route changes require explicit opt-in via UNIFI_WRITE_ENABLED=true. Destructive operations (block, restart) additionally require per-call confirm=true.
• Multi-controller — manage home and office networks from a single MCP instance. Each controller authenticates independently with separate sessions.

Multi-controller support

export UNIFI_HOME_HOST="192.168.1.1"
export UNIFI_HOME_USERNAME="admin"
export UNIFI_HOME_PASSWORD="home-password"
export UNIFI_OFFICE_HOST="10.0.0.1"
export UNIFI_OFFICE_USERNAME="admin"
export UNIFI_OFFICE_PASSWORD="office-password"

Pass controller="office" to any tool. Omit for the first configured controller.

Security model

Layer	Mechanism
Write gate	UNIFI_WRITE_ENABLED=true required for any mutation
Destructive confirm	unifi_block_client and unifi_restart_device require confirm=true
Credential scrubbing	Passwords, cookies, CSRF tokens, session IDs stripped from errors
Bearer auth	Optional UNIFI_MCP_API_TOKEN for HTTP transport
Session isolation	Each controller authenticates independently
SSL configurable	UNIFI_VERIFY_SSL=true for environments with proper certs
2FA support	TOTP via UNIFI_TOTP_SECRET (base32 encoded)

Sidereal integration

      "type": "stdio",
      "command": "uv",
      "args": ["--directory", "~/src/ubiquiti-unifi-blade-mcp", "run", "ubiquiti-unifi-blade-mcp"],

Webhook trigger patterns

• Device state changes — unifi_devices returns state (connected/disconnected/upgrading), enabling alerts on AP/switch failures
• New/unknown clients — unifi_clients with blocked status for intrusion detection workflows
• Firmware availability — unifi_devices flags UPGRADE_AVAILABLE for maintenance scheduling
• Firewall audit — unifi_firewall + unifi_port_forwards for periodic security posture checks

Development

make install-dev    # Install with dev + test dependencies
make test           # Unit tests (mocked, no controller needed)
make check          # Lint + format + type-check
make run            # Start MCP server (stdio)
