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 | $0.00700 | $0.00700 |
| Opus 5.5 | $0.00280 | $0.00280 |
| Sonnet 5.5 | $0.00140 | $0.00140 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
mcp_flexsim 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 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.
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.

Repository Guidelines
Project Structure & Module Organization
mcp_server/flexsim_mcp.pyhosts the FastMCP server and FlexSimPy controller logic; treat it as the single entry point for runtime changes.utility/contains shared helpers (config.py, build automation, integration harness) that are imported dynamically—update these with backwards compatibility in mind.tests/integration/provides stdio client tests that exercise live FlexSim interactions; add new end-to-end checks here.depends/FlexSimPyis a submodule for the FlexSimPy SDK, whileFlexSimDev/programmirrors a local FlexSim installation used during builds.config.tomlandmcp_server_config.jsondefine install locations and MCP launch defaults; prefer editing copies rather than committing per-user paths.
Build, Test, and Development Commands
- Install and lock dependencies with
uv syncfrom the repo root; commituv.lockwhen dependencies change. - Run the MCP server interactively via
uv run mcp_server/flexsim_mcp.py --test-modeto verify tool availability. - Check FlexSimPy build status or trigger a rebuild with
uv run python utility/build_automation.py --statusor--install. - Execute integration smoke tests using
uv run python tests/integration/test_mcp_client.py; the script launches the server and validates tool calls. - Use
uv run python utility/integration_test.pywhen you need a GUI-backed FlexSim sanity check.
Coding Style & Naming Conventions
- Python code uses 4-space indentation, type hints, and Pydantic models for inputs; mirror patterns already present in
flexsim_mcp.py. - Keep log messages concise and actionable—prefer
logger.info/logger.errorover prints inside server modules. - Follow snake_case for functions and variables, PascalCase for Pydantic models, and prefix async tool functions with
flexsim_to align with existing tool registry names. - Run
uv run python -m compileall mcp_server utilitybefore large refactors when you need an extra syntax check.
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.

mcp_flexsim AGENTS.md is an instructions file published in the GitHub repository SethGame/mcp_flexsim (9 stars, last pushed 11mo ago), licensed MIT. It adds 700 tokens to every session, about $0.0028 per session on Opus 5.5. 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.
