The KiCad MCP autoroute tool has its own async job tracking, "the same pattern as freecad-mcp's," and a shared mcp-jobs library was pulled out of freecad-mcp but never adopted there. The author says it's now a third copy and the copies differ (thread per job with 3 concurrent versus a single FIFO worker). Each CAD tool gets its own MCP server, and each server re-invents the same plumbing.
