AI agents call graph_query to retrieve information from Memsolus MCP Server 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 data from a knowledge graph to answer questions, which is a retrieval operation with no side effects. However, the severity is medium rather than low because the knowledge graph contains persistent long-term memory for AI agents, including 'facts, preferences, and relationships.' Misuse could expose sensitive stored information or allow an agent to reason over private data it…
From the tool's definition Tool description indicates it 'Answer[s] a natural language question using the knowledge graph' and is used 'for complex relational questions.' The verb 'Answer' and the read-only nature of querying a knowledge graph without modification indicate a Read…

Answer a natural language question using the knowledge graph. Use for complex relational questions like. It is categorised as a Read tool in the Memsolus MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Memsolus MCP Server MCP server in PolicyLayer and add a rule for graph_query: 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 Memsolus MCP Server. Nothing to install.
graph_query 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 graph_query 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 graph_query. 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.
graph_query is provided by the Memsolus MCP Server MCP server (memsolus/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
