Traverse outward relationship dependencies from an entity.
AI agents call get_entity_graph to retrieve information from SQLite Project Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns relationship graph data from the SQLite database. It has no side effects—it does not create, modify, delete, or execute operations. The operation is purely informational, retrieving existing entity relationships for inspection. This is a clear Read category classification.
From the tool's definition Tool name 'get_entity_graph' and description 'Traverse outward relationship dependencies from an entity' indicate a query/retrieval operation. The verb 'traverse' and 'get' are read-only operations that retrieve and return data without modifying state.
Attacks that exploit this kind of access
Traverse outward relationship dependencies from an entity. It is categorised as a Read tool in the SQLite Project Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the SQLite Project Memory MCP server in PolicyLayer and add a rule for get_entity_graph: 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 SQLite Project Memory MCP. Nothing to install.
get_entity_graph 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 get_entity_graph 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 get_entity_graph. 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.
get_entity_graph is provided by the SQLite Project Memory MCP server (webrtcgame/sqlite-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
