What is gemini-mcp AGENTS.md?

Repository instructions for a Gemini MCP server that connects an AI agent to Google's Gemini API. The server supports image, video, and music generation, file handling, model listing, and credential checks.

Use it when developing, reviewing, or changing the gemini-mcp repository and its media-generation tools.

It gives coding agents the project-specific rules and architecture they need when working on this media-generation integration.

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	$0.00004	$0.00004
Opus 5.5	$0.00002	$0.00002
Sonnet 5.5	$0.00001	$0.00001
Haiku 4.5	$0.00000	$0.00000

Security

Grade A, and why

gemini-mcp AGENTS.md 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 29d 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.

Changes

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.
