Quality Score

70/100

Our assessment of partreel

partreel scores 70/100 on our quality scale, 3788th of 4,632 Development & Engineering skills we index.

Its MCP Server is 3429 KB long, well organised into 21 sections with 1 code example: long enough that it reads more like full documentation than a focused instruction file, which agents can find harder to follow.

It has 3 GitHub stars, so there is little community track record yet; judge it on its content.

Maintenance, license and trust

The repository was last updated 26 days ago, so partreel is actively maintained.
No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
Its trust signals score 80/100, with 2 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Safety scan

No issues found

Our scan of the first 100 KB of the file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful.

Frequently asked questions

How do I install partreel?: Run claude mcp add mingyo186 -- npx -y github:mingyo186/partreel. The install tabs above show the steps for each supported agent.
Which AI agents does partreel work with?: It is written for Claude Code and Claude Desktop, as a MCP Server file. Other agents that read the same format can often use it too.
Is partreel safe to use?: Our scan of the first 100 KB of the file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful. It declares no license and scores 80/100 on trust signals. Skills are instructions an agent will follow, so read the file before installing it and do not approve commands you do not understand.
Is partreel still maintained?: The repository was last updated 26 days ago, so partreel is actively maintained.

PartReel — open KiCad parts registry for humans & AI agents

No login. No paywall. Machine-verified. Every part ships as a bundle of KiCad footprint (.kicad_mod) + symbol (.kicad_sym) + 3D model (STEP + GLB), generated from manufacturer-datasheet dimensions and checked by automated quality gates on every deploy.

Site: https://partreel.com · API: https://partreel.com/api/ · MCP server: https://mcp.partreel.com/mcp · Agent guide: https://partreel.com/agents/

Why this exists

The official KiCad library is excellent — use it when it has your part. PartReel focuses on parts the official library doesn't cover (checked against GitLab master before we add anything).
Aggregator sites lock downloads behind sign-ups; agents and scripts can't use them. Everything here is a plain URL.
AI agents regenerate footprints from scratch every time — wasteful and unverified. PartReel is the place to fetch a verified part instead, and report back (field_reports in the API).

Provenance — verify us, don't trust us

Every part's API entry (/api/v1/parts/<id>.json) carries machine-readable provenance: the exact datasheet figure/table each dimension came from (dimensions_source), the generator source file in this repo, the quality gates it passed, and field-usage reports. Gates run in CI on every push and block deployment on failure — see .github/workflows/deploy.yml.

| Gate | Checks | |---|---| | validate_kicad.py | s-expression structure, pads, layers, pin-1 | | KLC drawing rules | silk 0.12 / fab 0.10 + pin-1 chamfer / courtyard 0.05 | | check_overlap.py | no overlapping text in previews | | check_render.py | files exist, SVG pads/outlines match source, pages/API present, datasheet cited | | check_zfight.py | no coplanar z-fighting faces, pins are individual bodies | | validate_step.py | STEP solids pass FreeCAD kernel isValid |

For AI agents

Static JSON API, no auth, no rate limit: /api/v1/parts.json
Remote MCP server (nothing to install): claude mcp add --transport http partreel https://mcp.partreel.com/mcp — tools: search_parts, get_part, list_parts, submit_part, report_feedback, request_part, how_to_contribute
Machine guide: /llms.txt
The loop: search → use → if a part is missing, build it from the datasheet and submit_part — it is shared with every agent instantly (labeled unverified/staging), then hourly CI gates + review promote it to verified.
request_part generates parametric families (pin headers, LDOs) server-side in ~5 min; the PR path (CONTRIBUTING-AGENTS.md) remains for 3D models and edits.
