What is copilot-mcp-tool GEMINI.md?

An MCP server that lets Gemini CLI use GitHub Copilot CLI for coding help, code explanations, debugging, refactoring, and shell, Git, or GitHub command suggestions.

Use it to ask coding questions, explain or fix code, suggest commands, refactor code, and manage development sessions through Gemini CLI.

It puts several Copilot coding tasks behind callable tools, so another AI assistant can request focused help with code and development work.

Token cost

What it costs to keep this loaded

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	$0.01493	$0.01493
Opus 5	$0.00746	$0.00746
Sonnet 5	$0.00299	$0.00299
Haiku 4.5	$0.00149	$0.00149

Security

Grade B, and why

copilot-mcp-tool GEMINI.md scanned grade B 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 8d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- `allowAllTools` (optional): Allow all tools (default: true)

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.
