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 | $0.01051 | $0.01051 |
| Opus 5 | $0.00526 | $0.00526 |
| Sonnet 5 | $0.00210 | $0.00210 |
| Haiku 4.5 | $0.00105 | $0.00105 |
Grade A, and why
claude-gemini-mcp-server GEMINI.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 9d 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.

Gemini Project Context (GEMINI.md)
This document provides essential context for the Gemini agent to ensure efficient and accurate development assistance for this project.
1. Project Overview & Core Technology
- Description: This is a Node.js server that implements the Model Context Protocol (MCP).
- Core Dependency: The server's primary function is to act as a wrapper around the
geminicommand-line tool. - Main File: The main application logic is contained within
server.js.
2. Architectural Constraints & Conventions
- MCP Compliance: The server must strictly adhere to the MCP specification.
- Tool Responses: A critical constraint is that tool responses must not include
tool_useobjects in thecontentarray. All actionable suggestions (like code changes) must be formatted as markdown within atextobject. - Code Suggestion Format: The established convention for code suggestions is a markdown block containing:
- A
**Rationale:**section explaining the change. - An
Old Code:block. - A
New Code:block.
- A
- Suggestion Parsing: The server uses a dedicated
parseActionableSuggestionfunction to extract--- OLD_CODE ---and--- NEW_CODE ---blocks from thegeminiCLI's output.
3. Security & Validation Context
This server implements several security and validation layers to ensure safe operation:
- Working Directory Sandboxing: Path traversal is prevented by ensuring all file paths resolve within the project's working directory. (See
validateFilePath()inserver.js:75-77) - Binary File Rejection: The server detects and rejects binary files by analyzing for null bytes and non-printable characters. (See
validateFileAccess()inserver.js:107-112) - Input Sanitization: All user-provided inputs are sanitized to remove control characters and prevent injection attacks. (See
sanitizeInput()inserver.js:132-145) - Resource Limits: Strict file size and prompt length limits are enforced. (See
configinserver.js:47-48)- Max file size: 1MB
- Max prompt length: 100,000 characters
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.
