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 | $0.12487 | $0.12487 |
| Opus 5 | $0.06243 | $0.06243 |
| Sonnet 5 | $0.02497 | $0.02497 |
| Haiku 4.5 | $0.01249 | $0.01249 |
Grade A, and why
gemini-mcp CLAUDE.md scanned grade A with 2 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 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.

Guidance for Claude working in this repo.
TL;DR
v0.6.0: Google Gemini image-generation MCP server. Wraps the Generative
Language REST API (https://generativelanguage.googleapis.com/v1beta) and
exposes 13 tools to Claude over stdio: text→image and image→image generation,
multi-turn conversational editing, consistent image sets, video generation
(omni, gemini_video_generate), music generation (Lyria clips/pro,
gemini_music_generate), model listing (Nano Banana / Nano Banana Pro
family), Files API upload/list/delete, and a credential
healthcheck (gemini_healthcheck). Reference images can come from an
https URL the server fetches (images_url), a Files API reference
(images_file_uris), local file paths, raw base64 / data URIs, or the macOS
clipboard; video from a public YouTube URL or a local upload. Video and music ride the same
Interactions endpoint as gemini_interact — the tool naming is media-first
(gemini_<media>_<action>). Realtime Lyria (WebSocket) is intentionally
not implemented (see the video/music design spec).
A hosted deployment additionally serves: gemini_get_upload_url (signed PUT
upload URLs — zero-auth-header uploads from a shell), a persistent per-account
character/style library (gemini_save/list/delete_character/_style, applied
via characters/style params on the generation tools), images_r2_keys
inputs, max_wait_ms wait-then-hand-off on generation tools, and a bundle_url
zip on multi-image gemini_image_set results.
Auth is a Google API key (GEMINI_API_KEY) sent in the x-goog-api-key
header — Gemini does not use Authorization: Bearer. Because the model is
baked into the URL path (/models/{model}:generateContent) rather than the body,
this is the bearer/direct-API archetype with a custom twist: a thin call()
wrapper over the fleet-shared createApiClient (configured with a non-Bearer
tokenHeader), not a hand-rolled fetch and not a stock Bearer client.
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.

gemini-mcp CLAUDE.md is an instructions file published in the GitHub repository chrischall/gemini-mcp (0 stars, last pushed today), licensed MIT. It adds 12,487 tokens to every session, about $0.0624 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
