# search_jlcpcb_parts

Search JLCPCB parts catalog by specifications. Searches the local JLCPCB database (must be downloaded first with download_jlcpcb_database). Provides real pricing, stock info, and library type (Basic parts = free assembly). Use this to find components with exact specifications and cost optimization. For a verified, ready-to-use KiCAD footprint/symbol/3D bundle (rather than sourcing/stock data), use search_parts_registry instead.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "search_jlcpcb_parts",
    "arguments": {}
  }
}
```

## Why search_jlcpcb_parts is rated Low

This is a read-only query tool that retrieves component specifications and availability from a static catalog. While the context involves PCB manufacturing and component sourcing (which could lead to financial decisions downstream), the tool itself performs only data retrieval with no side effects, reversible operations, or irreversible actions.

From the tool's own definition: "Tool searches and queries a local JLCPCB parts catalog database, retrieving pricing, stock information, and library type data. Verbs and actions are inherently non-destructive: 'Search', 'Provides', 'find components'."

## Use case

AI agents call search_jlcpcb_parts to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches KiCAD-MCP-Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_jlcpcb_parts": {}
  }
}
```
