WHAT IT DOES

What search_jlcpcb_parts does on KiCAD-MCP-Server

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.

RISK

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 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'.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_jlcpcb_parts safely

PolicyLayer is an MCP gateway: it sits between your AI agents and KiCAD-MCP-Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_jlcpcb_parts, this is the rule to start with:

search_jlcpcb_parts Allowed

search_jlcpcb_parts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every search_jlcpcb_parts call is checked against it from then on.

FAQ

Questions about search_jlcpcb_parts

What does the search_jlcpcb_parts tool do? +

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. It is categorised as a Read tool in the KiCAD-MCP-Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on search_jlcpcb_parts? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for search_jlcpcb_parts: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches KiCAD-MCP-Server. Nothing to install.

What risk level is search_jlcpcb_parts? +

search_jlcpcb_parts is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit search_jlcpcb_parts? +

Yes. Add a rate_limit block to the search_jlcpcb_parts rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block search_jlcpcb_parts completely? +

Set action: deny in the PolicyLayer policy for search_jlcpcb_parts. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides search_jlcpcb_parts? +

search_jlcpcb_parts is provided by the KiCAD-MCP-Server MCP server (mixelpixx/kicad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
