[Network] Search memories stored for this site. Requires network connection. Returns matching engrams.
AI agents call recall to retrieve information from Inkwell MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The recall tool performs a query/search operation on stored memories for the site. It retrieves data without creating, modifying, deleting, or executing any actions. This is a straightforward read-only operation that matches the 'Read' category definition. The network requirement does not change the classification. Severity is low because searching stored memories poses minimal risk even if misused by an AI agent.
From the tool's definition Tool description explicitly states 'Search memories' and 'Returns matching engrams' — retrieval operations with no modification or side effects.

[Network] Search memories stored for this site. Requires network connection. Returns matching engrams. It is categorised as a Read tool in the Inkwell MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Inkwell MCP Server MCP server in PolicyLayer and add a rule for recall: 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 Inkwell MCP Server. Nothing to install.
recall 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 recall 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 recall. 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.
recall is provided by the Inkwell MCP Server MCP server (mumega-com/inkwell). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
