What is STAAD-MCP AGENTS.md?

Project instructions for DP065U/STAAD-MCP, a Windows-only bridge between AI agents and Bentley STAAD.Pro. They document the project structure, development commands, architecture, and testing.

Use them when developing or maintaining the STAAD-MCP codebase, running unit or integration tests, and understanding its connection, server, and sandbox components.

They give contributors the rules needed to build, lint, format, and test the bridge consistently, including which tests require STAAD.Pro on Windows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00880	$0.00880
Opus 5.5	$0.00352	$0.00352
Sonnet 5.5	$0.00176	$0.00176

Security

Grade A, and why

STAAD-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 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.

Origin

This is a copy

91% identical to openstaad-mcp AGENTS.md — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Project Overview

MCP server bridging AI agents to Bentley STAAD.Pro via the OpenSTAAD COM API.
Windows-only (pywin32/COM). Python 3.11+. See README.md for full details.

Build & Test

pip install -e ".[dev]"          # Install with dev dependencies
ruff check . ; ruff format --check .  # Lint + format check
ruff check --fix . ; ruff format .    # Auto-fix
pytest                                # Unit tests (any OS, no STAAD needed)

Architecture

Component	Purpose
`main.py`	CLI entry point, transport setup (stdio/HTTP)
`server.py`	MCP tool definitions (`discover_api`, `read_skills`, `execute_code`, `get_status`)
`connection.py`	Multi-instance management via Windows ROT scan, STA-thread COM dispatch
`sandbox/executor.py`	AST-validated sandboxed `exec()` with stdout/stderr capture
`sandbox/com_proxy.py`	COM object proxy — blocks internal attrs, validates file paths
`sandbox/ast.py`	AST validation, format-string bypass detection, last-expr rewriting
`sandbox/const.py`	Allowlists for builtins, exceptions, and module attributes
`sandbox/path_validator.py`	Blocks writes to protected dirs, detects UNC paths (NTLM relay prevention)
`http_middleware.py`	`SecFetchMiddleware` — blocks cross-origin browser requests
`skills.py`	Skill discovery from `staad_skills/` with YAML frontmatter extraction

Conventions

Line length: 120 characters
Linter/formatter: Ruff (Black-compatible). Config in pyproject.toml
Ruff rules: E, F, W, I, UP, B, SIM, RUF (ignoring E501, RUF200)
Tests: pytest + pytest-asyncio (asyncio_mode = "auto"). Mark integration tests with @pytest.mark.integration
100% test coverage expected for new code
All async tests use pytest-asyncio auto mode — no manual event loop setup
Limit the number of if-else branches: Use polymorphism (or equivalents) when possible.
Single responsibility: Aim for functions and classes with a single responsibility.
Data validation: Use Pydantic models when runtime validation is needed. For static type checking, use type hints.

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.
