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 | $0.00996 | $0.00996 |
| Opus 5 | $0.00498 | $0.00498 |
| Sonnet 5 | $0.00199 | $0.00199 |
| Haiku 4.5 | $0.00100 | $0.00100 |
Grade A, and why
google-jules-mcp-server 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 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.
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.

AGENTS.md
Project Overview
- Core Stack: Node.js (>=22.0.0), TypeScript, Model Context Protocol (MCP) SDK.
- Purpose: Google Jules API (v1alpha) integration server enabling LLM tool calling via MCP stdio transport.
Single Source of Truth for Code Style
- Do NOT duplicate style configurations in this file.
- Rule: You must dynamically check the local project configuration files (
package.json,tsconfig.json,.prettierrc.json, oreslint.config.jsif present) to read the formatting and lint rules. - Validation: Run the verification commands listed below before committing or completing any task to ensure code complies with local rules.
Build & Test Commands
- Install Dependencies:
npm installornpm ci - Compile:
npm run build - Type Check:
npm run typecheckornpx tsc --noEmit - Lint Verification:
npm run lint(ESLint flat config) - Format Check:
npm run format(Prettier check) - Format Fix:
npm run format:fix(Prettier fix) - Run Tests:
npm test(Vitest unit test suite) - Coverage:
npm run test:coverage(Vitest coverage report) - Smoke Test:
JULES_LIVE_SMOKE_TEST=1 npm run test:smoke(Opt-in live API check)
MCP & Tool Constraints
- Schema Validation: Use
zodfor parsing and defining tool schemas. Every API response is validated at runtime with Zod (z.infer). - Tool Registration: Registration order in
src/server.tsmust strictly matchTOOL_NAMESarray (Sources tools, Session tools, then Activity tools) to ensuretests/server.test.tspasses. - API Mapping: Map parameters accurately to Google Jules API v1alpha specifications.
Boundaries & Permissions
- ALWAYS: Run local build, type-checking, linting, and tests before finalizing any code modification.
- NEVER: Hardcode API credentials or environment variables; always look for
JULES_API_KEYin process environment variables. - NEVER: Include AI co-author trailers in git commits.
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.

google-jules-mcp-server AGENTS.md is an instructions file published in the GitHub repository georgeracu/google-jules-mcp-server (2 stars, last pushed today), licensed MIT. It adds 996 tokens to every session, about $0.0050 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
