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

qcad-mcp CLAUDE.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 9d 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

78% identical to freecad-mcp CLAUDE.md — 4 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.

What it actually says

qcad-mcp — Claude Code Guide

Overview

QCAD MCP server — DXF/DWG floor plans to SVG preview + STL extrusion via MCP tools and REST API

Standards

  • FastMCP 3.2+ portmanteau tool pattern — tools use operation enum param
  • Responses: structured dicts with success, message, domain-specific fields
  • Dual transport: stdio (Claude Desktop) + HTTP (MCP_TRANSPORT=http)
  • See mcp-central-docs for fleet-wide coding standards

Key Files

  • README.md — full documentation
  • pyproject.toml — build config and entry points
  • AGENTS.md — OpenAI Codex agent context (if present)
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.
