Search and retrieve all product manufacturers.
AI agents call search_manufacturers to retrieve information from DigiKey MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to retrieve manufacturer information from the DigiKey catalog. It has no side effects, does not modify data, execute code, delete records, or commit financial transactions. The retrieval of static manufacturer reference data poses minimal security risk even if an AI agent accesses it without restriction.
From the tool's definition Tool name 'search_manufacturers' and description 'Search and retrieve all product manufacturers' indicates retrieval of manufacturer data with no modification, deletion, or execution of operations.

Register the DigiKey MCP Server MCP server in PolicyLayer and add a rule for search_manufacturers: 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 DigiKey MCP Server. Nothing to install.
search_manufacturers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_manufacturers 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.
Set action: deny in the PolicyLayer policy for search_manufacturers. 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.
