memory_queryMemory
AI agents call memory_queryMemory to retrieve information from Chain Debugger MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'query' verb combined with 'Memory' suggests this tool retrieves or searches stored memory/context data without modification. No evidence of side effects, destructive operations, code execution, or financial impact. Despite empty description, the naming convention and peer tools indicate this is a retrieval operation. Classified as Read with medium-high confidence due to lack of explicit documentation.
From the tool's definition Tool name 'memory_queryMemory' with 'query' prefix indicates data retrieval operation. Naming pattern matches other Read operations on this server (get_alert_by_id, megaeth_getLogs). Tool description is empty, reducing confidence in this classification.
Attacks that exploit this kind of access
memory_queryMemory. It is categorised as a Read tool in the Chain Debugger MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Chain Debugger MCP Server MCP server in PolicyLayer and add a rule for memory_queryMemory: 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 Chain Debugger MCP Server. Nothing to install.
memory_queryMemory 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 memory_queryMemory 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 memory_queryMemory. 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.
memory_queryMemory is provided by the Chain Debugger MCP Server MCP server (optimusopus/chain-debugger-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
