Search Components
Structured D1 search by MPN, manufacturer, LCSC, capability, package, footprint UUID, same-footprint reference, pin count, interface, JLC class, assembly status, and asset availability.
Semantic Search Components
Workers AI + Vectorize semantic search for parts by natural language requirements.
List Categories
List every distinct component category currently in the registry with its component count, sorted by count descending. Call this before search_components/semantic_search_components when the exact category name isn't known, to pick the right `category` or `capability` filter value instead of guessing.
Get Component
Fetch one component with profile Markdown, interfaces, assets, preview-image reference, procurement snapshots, and recent stock snapshots if present.
Upsert Component
Add or update a component. Requires Authorization: Bearer <ADMIN_TOKEN>.
Get Application Template
Fetch a verified application-circuit template (topology + value rules) by LCSC id, stored verbatim as pushed by the schematic-gen pipeline. Consumers must re-validate and respect the approved flag.
List Application Templates
List stored application templates (summary rows, no JSON blobs). Pass approved=true to list only human-approved templates.
Upsert Application Template
Store an application template verbatim, keyed by LCSC. The server copies verified/approved from the payload and NEVER flips them — approval is a human act upstream. Requires admin auth.
Add Component Asset
Attach datasheets, EasyEDA symbols, footprints, 3D models, and JLC/product images. Use asset_type=jlc_image for the JLC part image. Requires admin auth.
Add Stock Snapshot
Record volatile stock evidence. Prefer add_procurement_snapshot for durable JLC class and price-break evidence; do not use stock snapshots for embeddings.
Add Procurement Snapshot
Record stable-ish procurement evidence such as JLC Basic/Extended class, assembly status, MOQ, and price-break table. Does not record live stock.
Update Component Profile
Store standardized Markdown component intelligence for search and embeddings: capabilities, package/footprint, pins, power modes, design notes, and datasheet evidence.
Refresh Component Embedding
Regenerate a component embedding and upsert it into Vectorize. Requires admin auth.
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.

Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.
MCPBundles probed 13 tools on the live server. The tool list on this page reflects what was discovered at the last refresh — connect your client to see the full set available to your session.
No provider sign-in was required during MCPBundles' probe. Your client may still need MCPBundles credentials depending on how you connect.
