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 | $0.00384 | $0.00384 |
| Opus 5.5 | $0.00154 | $0.00154 |
| Sonnet 5.5 | $0.00077 | $0.00077 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade C, and why
mcp-ShellGateway 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.

MCP Linux Shell Server - Copilot Instructions
This is an MCP (Model Context Protocol) server project that provides Linux CLI access through the MCP protocol.
Project Context
- Project Type: MCP Server
- Language: Python 3.8+
- Framework: MCP SDK (Model Context Protocol)
- Purpose: Provide safe Linux shell command execution for Claude Dev mode
Key Guidelines
- MCP Protocol Compliance: Always follow MCP protocol specifications from https://modelcontextprotocol.io/
- SDK Reference: Use the MCP Python SDK reference at https://github.com/modelcontextprotocol/create-python-server
- Security First: Implement proper error handling and input validation for shell commands
- Async Programming: Use async/await patterns throughout the codebase
- Type Safety: Include proper type hints for all functions and methods
Architecture
linux_shell_server/main.py: Main server implementation with MCP handlerslinux_shell_server/__init__.py: Package initialization- Tools provided:
execute_command,change_directory,get_current_directory
Code Standards
- Follow PEP 8 style guidelines
- Use Black for code formatting
- Include comprehensive error handling
- Add docstrings for all public functions
- Maintain compatibility with Python 3.8+
Testing
- Write tests for all shell execution functionality
- Mock subprocess calls in tests
- Test error conditions and edge cases
- Ensure async function testing with pytest-asyncio

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.
