Vibe-Coding Hardware MCP Server (`vibe-hardware-mcp`)

A zero-dependency Python 3 Model Context Protocol (MCP) server (calligraphy_mcp_stdio.py) for local KiCad .kicad_pcb & Specctra .dsn parsing, PCB transmission-line impedance & IPC-2152 current calculation, local Design-for-Manufacturing (DFM) rule auditing, and multi-layer PCB trace routing.

Architecture & Included MCP Tools (`calligraphy_mcp_stdio.py`)

This repository contains the complete, zero-dependency Python 3 MCP server implementation in calligraphy_mcp_stdio.py (containerized via Dockerfile):

1. Local Offline PCB Analysis, Impedance & DFM Tools (100% Local Execution)

Tool Name	Execution	Description
`analyze_kicad_pcb`	Local Python	Parses `.kicad_pcb` S-expression files locally to extract copper layer stackup (`F.Cu`, `B.Cu`, `In1.Cu`..), board outline dimensions (`Edge.Cuts` in `mm`), footprint count, SMD/THT pad counts, fine-pitch (`<= 0.50 mm`) pad density, netlist count, and routed track/arc/via statistics.
`analyze_specctra_dsn`	Local Python	Parses Specctra `.dsn` autorouter files locally to extract units, resolution, signal/power layers, board boundary dimensions, component pin count, net connectivity, and design rule clearances/widths.
`calculate_pcb_trace_impedance`	Local Python	Closed-form IPC-2141A / Hammerstad-Jensen microstrip & stripline characteristic impedance ($Z_0$), edge-coupled differential pair impedance ($Z_{\text{diff}}$), propagation delay (`ps/mm`), and IPC-2152 DC current capacity / temperature-rise solver.
`audit_pcb_dfm_rules`	Local Python	Audits `.kicad_pcb` and `.dsn` trace widths, clearances, via drill diameters, and annular rings locally against `standard_2l`, `standard_4l`, and `fine_hdi` fabrication limits (JLCPCB / PCBWay).
`calligraphy_list_gallery_boards`	Local Python	Returns the built-in catalog of 13 verified open-source reference PCBs (`100.0%` routed completion, `0` native KiCad copper DRC violations).

2. Optional Cloud Co-Processor Tools (Multi-Layer 3D PCB Routing Offload)

For dense multi-layer boards that require full 3D trace routing, G1 circular arc smoothing, teardrop pad reinforcement, and turnkey Gerber/Excellon/IPC-D-356 .ZIP generation, the server also exposes optional co-processor tools (calligraphy_preflight_audit, calligraphy_compile_board, calligraphy_get_job_status, calligraphy_download_fab_bundle, calligraphy_route_pcb).

B3.4/5.0

Scored 2026-11-10 16:19 across 15 tools

Disambiguation3/5

Most tools have clearly distinct roles (local analysis vs. DFM audit vs. impedance calc vs. job/payment lifecycle), but calligraphy_route_pcb is explicitly declared an alias of calligraphy_compile_board, creating a genuine duplicate entry an agent could misselect. There is also soft overlap between calligraphy_preflight_audit and analyze_kicad_pcb (both ingest the same file modes and inspect readiness), and between calligraphy_lookup_b2b_invoice and calligraphy_get_job_status.

Naming Consistency4/5

All names are snake_case with a verb-first construction (analyze_, calculate_, audit_, calligraphy_compile_board, calligraphy_get_job_status), and the calligraphy_ prefix cleanly marks the hosted service namespace versus local tools. Minor deviations: calligraphy_preflight_audit is noun-noun rather than verb_noun, and the 'pcb' token floats inconsistently (analyze_kicad_pcb vs audit_pcb_dfm_rules vs calligraphy_route_pcb).

Tool Count4/5

15 tools sits at the top of the comfortable range and each maps to a real step: local analysis, impedance/DFM checks, compile, status, payment (Stripe/Coinbase/stablecoin), download, invoice, purge, whitelist. The only clearly unearned slot is the redundant calligraphy_route_pcb alias, making it slightly bloated for the underlying workflow.

Completeness5/5

The surface covers a full lifecycle: input parsing (KiCad, Specctra), local physics/DFM analysis, compile/route, job status polling, three payment paths (Stripe checkout URL, Coinbase/x402, stablecoin tx verification), artifact download, invoicing, and vault destruction. Only marginal gaps exist (no job cancellation/refund or multi-job listing), which agents can work around via job_id status calls.
