    How to connect

    How to connect partreel to Claude

    The server address to paste into Claude settings:

    https://mcp.partreel.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect partreel to ChatGPT

    The server address to paste into ChatGPT settings:

    https://mcp.partreel.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    search_partsSearch the PartReel registry of verified KiCad components (footprint + symbol + 3D STEP/GLB, no login, CC-BY-4.0). Returns matching parts with ids. Use get_part for download URLs. Example queries: 'usb-c', 'jst ph 4pin', 'esp32', 'microsd', 'screw terminal'.
    get_partGet full detail for one part by id: parameters, verification status, datasheet, and absolute download URLs for .kicad_mod (footprint), .kicad_sym (symbol), .step and .glb (3D).
    list_partsList all parts in the registry (id, name, family, pins).
    report_feedbackReport real-world usage feedback for a part (e.g. 'fabricated 5 boards at JLCPCB, footprint fit perfectly' or 'pad 3 misaligned'). Feedback is recorded publicly on GitHub and builds the part's field-proven trust score. Please report after actually using a part — both successes and problems help.
    request_partRequest on-demand generation of a parametric part that isn't in the registry yet. The registry generates it (footprint+symbol+3D), runs quality gates, and publishes it within ~5 minutes. Pin-count families (use 'pins'): pin_header_254 (2.54mm), pin_header_200 (2.0mm), pin_header_127 (1.27mm) — pins 1-40. Variant families (use 'variant'): ht73xx (LDO Vout code: 7318,7325,7327,7330,7333,7335,7341,7350), ht78xx (7818,7825,7827,7830,7833,7850), sy8008 (grade a/b/c = 0.6A/1A/1.2A), max1704x (17048,17049). Always try get_part / search_parts first.
    how_to_contributeGet machine-readable instructions for adding a new part to the registry (file layout, metadata schema, quality gates, PR process). Use when a part is missing.
    submit_partUpload a part you built so it is SHARED IMMEDIATELY (status 'staging', unverified). It becomes searchable and downloadable right away; hourly CI then runs the full quality gates and opens a PR to promote it to the verified registry. Provide the full text of the .kicad_sym and .kicad_mod files plus metadata. Cite real datasheet dimensions in dimensions_source — copies of the official KiCad (CC-BY-SA) library are auto-rejected at promotion.
