AI agents call inspect to retrieve information from Engram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries information from the memory system without creating, modifying, deleting, or executing any operations. The actions described (viewing stats, looking up entities, listing banks) are fundamentally informational retrievals with no side effects.
From the tool's definition The tool description explicitly states "View memory stats, look up a specific entity, or list all banks" — all read-only operations (view, look up, list) with no modification or deletion capability.
Attacks that exploit this kind of access
View memory stats, look up a specific entity, or list all banks. It is categorised as a Read tool in the Engram MCP Server, which means it retrieves data without modifying state.
Register the Engram MCP server in PolicyLayer and add a rule for inspect: 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 Engram. Nothing to install.
inspect 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 inspect 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 inspect. 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.
inspect is provided by the Engram MCP server (reallyartificial/engram). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
