abaqus-codex-mcp: Instructions file for Codex

AGENTS.md

abaqus-codex-mcp AGENTS.md is an instructions file for Codex, OpenCode from MOBAI547800/abaqus-codex-mcp. It costs 343 tokens per session, scanned A, original, MIT.

Repository instructions for an OpenAI Codex connector that runs Abaqus, an engineering simulation program, through a local MCP server. They define required tests, file limits, and safety checks.

In plain words
What is it for?
Use them when developing or reviewing this connector, especially changes to tools, paths, jobs, scripts, tests, or simulation data.
Why use it?
They keep simulations and file operations within the intended workspace and prevent unsafe execution or misleading claims about test results.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Codex.

This is MOBAI547800/abaqus-codex-mcp's own configuration. It tells Codex and OpenCode how to work on abaqus-codex-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything abaqus-codex-mcp configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

abaqus-codex-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 7d 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.

What it actually says

Repository guidance

Scope

This repository implements a local STDIO MCP server for OpenAI Codex and Abaqus. Keep Abaqus execution local and constrain every file operation to ABAQUS_MCP_WORKSPACE_DIR.

Required checks

Before submitting changes:

.\.venv\Scripts\python.exe -m pytest tests -v

For packaging or dependency changes, reinstall into a clean virtual environment and run the MCP protocol tests in tests/test_cli.py.

Safety rules

  • Never add an arbitrary shell execution tool.
  • Never use shell=True.
  • Validate user-provided paths through security.validate_path.
  • Mark tools accurately with MCP read/write/destructive annotations.
  • Keep explicit confirmed=true gates for background submission, synchronous solving, and file deletion.
  • Keep run_script approval bound to the current SHA-256 and block high-risk AST findings by default. Never describe this as an OS sandbox.
  • Keep ODB selectors in JSON payloads consumed by the fixed worker; never insert user strings into Python source.
  • Persist job state atomically and prefer job_id for nested or duplicate jobs.
  • Do not claim a live Abaqus result from mocked tests.
  • Keep polishing model construction and contact extraction in fixed workers driven by JSON payloads. Never interpolate user values into Python source.
  • A polishing calibration is successful only after an independent final job passes G0-G7, including three-force balance and energy/penetration checks.
  • The fixed polishing workers require licensed Abaqus and are excluded from ordinary CPython coverage; validate them through the explicit live gate.
Changes

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.
