AI agents call store_search_all to retrieve information from Willow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs searches across collections, which is a read-only operation that retrieves data without modifying, deleting, or executing external operations. The severity is low because search operations have minimal blast radius—worst case is information disclosure of existing data.
From the tool's definition Tool name 'store_search_all' indicates searching functionality. Description begins 'Search across ALL SOIL collections simultaneously', which describes a query/retrieval operation with no side effects.

Register the Willow MCP server in PolicyLayer and add a rule for store_search_all: 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 Willow. Nothing to install.
store_search_all 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 store_search_all 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 store_search_all. 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.
store_search_all is provided by the Willow MCP server (rudi193-cmd/willow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
