starlink-blade-mcp

Local-first Starlink dish monitoring and control via the Model Context Protocol.

Talks directly to your dish over the local gRPC interface (192.168.100.1:9200) — no cloud API, no enterprise credentials, no internet dependency. Built on starlink-grpc-core, the same library that powers the Home Assistant Starlink integration.

Why this MCP?

	starlink-blade-mcp	starlink-enterprise-mcp	mcp-spacex
Interface	Local gRPC (dish hardware)	Enterprise cloud API	Public SpaceX API
Auth required	None (LAN access only)	OAuth2 enterprise credentials	None
Works offline	Yes	No	No
Residential dish	Yes	Enterprise fleet only	N/A (satellite tracking)
Dish control	Reboot, stow, unstow	Read-only telemetry	None
Obstruction map	12-wedge directional data	Aggregate only	None
Alert detail	22 flags with descriptions	Basic status	None
Token efficiency	Statistical summaries	Raw JSON	Raw JSON

Tools

Read (no authentication required)

Tool	Description
starlink_status	Dish identity, state, connectivity, throughput, SNR, orientation
starlink_alerts	Active alert flags (22 types) with human-readable descriptions
starlink_obstruction	Obstruction fraction, 12-wedge directional map, timing
starlink_history	Throughput/latency/power as min/avg/max summary (configurable window)
starlink_location	GPS coordinates (requires opt-in in Starlink app)
starlink_diagnostics	Hardware version, firmware, GPS satellites, alert count

Write (gated)

Tool	Description
starlink_reboot	Restart the dish (2-5 min downtime)
starlink_stow	Stow dish face-down for storage/transport
starlink_unstow	Resume normal satellite tracking

Write operations require dual gating:

1. STARLINK_WRITE_ENABLED=true environment variable
2. confirm=true parameter on each call

Quick Start

# Install
uv pip install starlink-blade-mcp

# Run (dish must be reachable at 192.168.100.1)
starlink-blade-mcp

# Or with uv
uvx starlink-blade-mcp

Configuration

Variable	Default	Description
STARLINK_DISH_ADDRESS	192.168.100.1:9200	Dish gRPC endpoint

STARLINK_MCP_HOST	127.0.0.1	HTTP transport bind address
STARLINK_MCP_PORT	8770	HTTP transport port

Network Requirements

The Starlink dish exposes an unauthenticated gRPC server at 192.168.100.1:9200 on the local network. Requirements:

• Device running the MCP must be on the Starlink LAN (or have a route to 192.168.100.1)
• No credentials or API keys needed
• GPS location requires opt-in: Starlink app > Settings > Advanced > Debug Data
• The dish's 192.168.100.1 address is not configurable

Starlink router (default)

Works out of the box. The dish, router, and your devices are all on the same network.

Third-party router in bypass mode (UniFi, pfSense, etc.)

In bypass mode, the Starlink router hands its CGNAT WAN IP to your router's WAN interface. The dish management interface (192.168.100.1) sits on a separate /24 subnet on the WAN side — your router won't know how to reach it without a static route.

Static route configuration (UniFi example):

UniFi Network > Settings > Routing > Static Routes:

Field	Value
Destination	192.168.100.0/24
Next Hop	WAN interface (Starlink-facing port)
Distance	1

Some router firmware also requires a secondary IP on the WAN interface in the 192.168.100.0/24 range (e.g. 192.168.100.2/24) for traffic to egress on that subnet. This depends on whether your firmware handles interface-scoped routes correctly — UniFi has been inconsistent here across versions.

Once the route is in place, both 192.168.100.1:9200 (gRPC) and 192.168.100.1:80 (Starlink web UI) become reachable from your LAN.

Remote / headless sites

Run the MCP server on any host that can reach 192.168.100.1 — a local machine, a container on a NAS, or any device on the Starlink-connected network.

Security Model

• No credentials stored or transmitted — the dish gRPC endpoint is unauthenticated by design
• LAN-only access — the gRPC interface is not exposed to the internet
• Write operations double-gated — environment variable + per-call confirmation
• No telemetry or phone-home — all data stays local between the MCP server and the dish
• No cloud API dependency — works during internet outages (ideal for monitoring them)

Token Efficiency

The starlink_history tool returns statistical summaries (min/avg/max per metric) rather than raw per-second samples. A 900-second window produces ~8 lines of output vs ~5,400 lines of raw data.
