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 5.1 | $0.00340 | $0.00340 |
| Opus 5.5 | $0.00136 | $0.00136 |
| Sonnet 5.5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade C, and why
mcp-nautobot copilot-instructions.md scanned grade C with 1 finding 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 2mo 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Copilot Instructions for MCP Nautobot Server
This is an MCP (Model Context Protocol) server project that integrates with Nautobot to provide IP address data retrieval capabilities.
Project Guidelines
- You can find more info and examples at https://modelcontextprotocol.io/llms-full.txt
- Refer to the official MCP Python SDK: https://github.com/modelcontextprotocol/create-python-server
- Follow async/await patterns for all I/O operations
- Use proper error handling and logging throughout the codebase
- Implement comprehensive type hints using Pydantic models
- Follow the MCP specification for tool definitions and responses
- Use environment variables for configuration (API keys, URLs, etc.)
- Implement rate limiting for Nautobot API calls to avoid overwhelming the server
- Ensure all responses are JSON serializable
- Include comprehensive docstrings and inline comments
- Follow Python best practices: PEP 8, proper exception handling, etc.
Key Components
- Nautobot API Client: Handles authentication and API communication
- MCP Tools: Define available functions for IP address data retrieval
- Error Handling: Comprehensive error handling for API failures
- Logging: Structured logging for debugging and monitoring
- Configuration: Environment-based configuration management
Testing Strategy
- Unit tests for individual components
- Integration tests with mock Nautobot responses
- Error scenario testing
- Type checking with mypy
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.
