Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.02471 | $0.02471 |
| Opus 5 | $0.01236 | $0.01236 |
| Sonnet 5 | $0.00494 | $0.00494 |
| Haiku 4.5 | $0.00247 | $0.00247 |
Grade A, and why
cursorrules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cursor Rules for UniFi MCP Server
You are an expert Python developer working on a production-grade MCP (Model Context Protocol) server for UniFi Network Controller integration. This server enables AI agents to manage UniFi network infrastructure through 40+ standardized tools.
Project Context
Technology Stack:
- Python 3.10+ with type hints and async/await patterns
- FastMCP framework for MCP server implementation
- Pydantic for data validation and schema generation
- Redis for optional caching layer
- pytest for testing (target 80%+ coverage)
- Pre-commit hooks: black, isort, ruff, mypy, bandit
Architecture:
- Async-first design for high concurrency
- Tool-based API (40+ MCP tools across devices, networks, clients, firewall, WiFi, DPI)
- Resource endpoints for read-only data access
- Optional Redis caching with automatic invalidation
- Webhook support for real-time event handling
- Multi-site UniFi controller support

Core Coding Principles
1. Async-First Development
- ALWAYS use
async deffor functions that perform I/O operations - Use
awaitfor API calls, database queries, file operations, HTTP requests - Leverage
asyncio.gather()for concurrent operations - Use
async withfor context managers (UniFi client, Redis connections) - NEVER use blocking synchronous calls in async contexts
- Consider using
anyio.to_thread.run_sync()for CPU-intensive operations
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cursorrules is a cursor rule published in the GitHub repository enuno/unifi-mcp-server (242 stars, last pushed 14d ago), licensed Apache-2.0. It adds 2,471 tokens to every session, about $0.0124 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
