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 | $0.00665 | $0.00665 |
| Opus 5 | $0.00332 | $0.00332 |
| Sonnet 5 | $0.00133 | $0.00133 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
imagen-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 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.
How it starts
The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
For contributors building and maintaining the MCP image generation server.
Project Structure & Module Organization
imagen_mcpis the canonical package andpython -m imagen_mcpis the MCP entry point.srcis an identity-preserving compatibility namespace.src/providers/holds provider implementations (openai_provider.py,gemini_provider.py),selector.pyfor auto-selection, andregistry.pyfor factory wiring.src/config/contains constants and settings;src/models/input_models.pydefines Pydantic request models.- Tests live in
tests/mirroring modules (test_selector.py,test_providers.py,test_server.py);run.shis the wrapper used by MCP clients; dependencies are declared inpyproject.toml.
Build, Test, and Development Commands
- Install locked development dependencies:
uv sync --extra dev. - Run the server locally:
uv run python -m imagen_mcp(or./run.shwhen invoked by clients); export at least one provider API key first. - Format and lint:
uv run ruff format imagen_mcp src tests && uv run ruff check imagen_mcp src tests. - Type check:
uv run mypy imagen_mcp src. - Tests:
uv run pytest(verbosity and discovery configured inpytest.ini). - Build and smoke distributions:
uv build, then clean-install the wheel/sdist and runtests/installed_distribution_smoke.pyoutside the checkout.
Coding Style & Naming Conventions
- Python 3.10+; Ruff line length 100; prefer explicit imports and typed signatures (mypy is strict: no implicit Optional, no untyped defs).
- Use snake_case for modules/functions, PascalCase for classes; keep provider IDs consistent with registry keys (
openai,gemini). - Keep side effects out of import time; guard script entry with
if __name__ == "__main__":when needed.
Testing Guidelines
- Add or extend tests in
tests/near the related module using thetest_*.py/Test*/test_*pattern. - Mock external APIs—reuse dummy env vars as in
tests/test_selector.py; avoid live requests in CI. - Cover new branching in provider selection, config defaults, and tool metadata (reasoning, confidence, alternatives) when relevant.
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.

imagen-mcp AGENTS.md is an instructions file published in the GitHub repository michaeljabbour/imagen-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 665 tokens to every session, about $0.0033 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.
