Aussie Broadband MCP Server — usage monitoring, outage tracking, and line diagnostics

aussiebb-blade-mcp

An MCP server that gives AI agents structured access to Aussie Broadband accounts. Built for the Model Context Protocol with token efficiency and operational security as first-class design goals.

Why this exists

Aussie Broadband has no public API program. The MyAussie portal API is undocumented and session-authenticated — not designed for programmatic access. The community-maintained pyaussiebb library (MIT, 6 years, powers the Home Assistant integration) has done the reverse-engineering work. This MCP wraps it with the guardrails that automated agents need:

• Token-efficient output — compact pipe-delimited format. A full service listing in ~50 tokens per service. Usage summaries with human-readable units (GB, %) and billing period context.
• Credential isolation — passwords and session cookies scrubbed from all error output. Bearer token auth for HTTP transport. No credential caching beyond the session.
• Diagnostic safety gate — line tests (connection check, port reset, loopback) require explicit opt-in via ABB_DIAGNOSTICS_ENABLED=true and per-call confirm=true. Port resets and connection kicks briefly interrupt service.
• Multi-account — manage home and business accounts from a single MCP instance. Each account authenticates independently.

How this differs from other ISP tools

	aussiebb-blade-mcp	Home Assistant integration	Raw pyaussiebb
Interface	MCP tools (any LLM agent)	HA entities + automations	Python library
Output	Token-optimised text	Sensor values	Raw dicts
Multi-account	Native (env var config)	One account per integration	Manual
Diagnostic safety	Double-gated (env + confirm)	Exposed as buttons	No gate
Auth transport	Bearer token + stdio	HA auth	None
Credential handling	Scrubbed from all output	HA secrets	Caller's responsibility

Quick start

# Install
uv pip install -e .

# Configure
export ABB_USERNAME="[e-mail]"
export ABB_PASSWORD="your-myaussie-password"

# Run
aussiebb-blade-mcp

Multi-account support

Manage multiple ABB accounts (household + business, parent + child) from a single MCP instance:

export ABB_ACCOUNTS="home,office"
export ABB_HOME_USERNAME="[e-mail]"
export ABB_HOME_PASSWORD="home-password"
export ABB_OFFICE_USERNAME="[e-mail]"
export ABB_OFFICE_PASSWORD="office-password"

Pass account="office" to any tool to target a specific account. Omit for the first configured account.

Single-account mode (plain ABB_USERNAME/ABB_PASSWORD) remains fully supported.

Security model

Layer	Mechanism
Credential scrubbing	Passwords, cookies, and tokens stripped from all error output
Diagnostics gate	ABB_DIAGNOSTICS_ENABLED=true required for any line test
Test confirmation	abb_run_test additionally requires confirm=true
Bearer auth	Optional ABB_MCP_API_TOKEN for HTTP transport
Session isolation	Each account authenticates independently; no credential sharing
No persistence	Credentials read from env at startup, never written to disk
Rate limiting	Automatic backoff on 429 responses from ABB API
MFA awareness	Documents MFA requirement for plan changes; does not bypass

Sidereal integration

Add to your MCP config:

{
  "mcpServers": {
    "aussiebb": {
      "type": "stdio",
      "command": "uv",
      "args": ["--directory", "~/src/aussiebb-blade-mcp", "run", "aussiebb-blade-mcp"],
      "env": {
        "ABB_USERNAME": "...",
        "ABB_PASSWORD": "...",
        "ABB_DIAGNOSTICS_ENABLED": "false"
      }
    }
  }
}

Webhook trigger patterns

The outage and usage tools are designed for downstream automation:

• Outage monitoring — abb_outages returns structured outage data suitable for Sidereal WatchPaths triggers or scheduled polling. Detect new outages, scheduled maintenance windows, and resolution events.
• Usage threshold alerts — abb_usage returns percentage-used and days-remaining, enabling threshold-based alerting (e.g. "notify at 80% usage with 10+ days remaining").
• Service status changes — abb_services returns service status, enabling detection of suspensions, activations, or plan changes.

Development

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