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 | $0.01287 | $0.01287 |
| Opus 5.5 | $0.00515 | $0.00515 |
| Sonnet 5.5 | $0.00257 | $0.00257 |
| Haiku 4.5 | $0.00129 | $0.00129 |
Grade A, and why
gemini-cli-mcp-slim AGENTS.md scanned grade A 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.

AGENTS.md — gemini-cli-mcp-slim
This file gives AI coding agents (Claude Code, Codex, Cursor, Gemini CLI, etc.)
the project-specific context required to work on this repository. Claude Code
reads it via CLAUDE.md, which is a one-line @AGENTS.md import shim.
What this project is
A thin bridge that exposes Google's Gemini CLI to MCP clients (Claude Code, Codex MCP, Cursor MCP, and other tools that speak MCP).
- Inputs: MCP tools (
consult_gemini,consult_gemini_with_files,web_search) - Outputs: argv-list subprocess invocation of the
geminiCLI (the binary path is configurable via$GEMINI_CMD)
History management, caching, streaming, and similar higher-level features are
deliberately not provided. The killer feature is cross-repository analysis
via directory (cwd) + include_directories.
Architectural decisions (load-bearing principles)
The author started this project from "don't blindly route your prompts and
code through someone else's wrapper." Recent supply-chain incidents
(xz-utils backdoor, postmark-mcp typosquat, npm chalk/debug compromise)
inform every design choice; default toward auditability.
- Auditable: the core implementation is a single file
(
src/gemini_cli_mcp_slim/server.py, ~290 lines) that anyone can read end-to-end in 30 minutes. If a feature would meaningfully grow this size, prefer dropping or omitting the feature over splitting the file. - Minimum dependencies:
[project].dependenciesinpyproject.tomlismcp>=1.0.0only. Adding a direct dependency expands supply-chain surface; always check whether the standard library can do the job first. - Forward-compatible: known flags are typed parameters; unknown / rare
flags flow through
extra_args: string[]verbatim. The server should not need to be re-released every time the upstreamgeminiCLI grows a new flag. - Transparent: every subprocess invocation logs its full argv to stderr
(
logger.info("exec %s ...")). - No shell: always use
asyncio.create_subprocess_execwith an argv list.shell=Trueand string-concatenated commands are forbidden. - Configurable binary: keep
$GEMINI_CMDworking so users can swap or wrap thegeminibinary.
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-cli-mcp-slim AGENTS.md is an instructions file published in the GitHub repository tksfjt1024/gemini-cli-mcp-slim (0 stars, last pushed 6mo ago), licensed MIT. It adds 1,287 tokens to every session, about $0.0051 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
