Fetch an entity and optionally include related metadata, content, and events.
AI agents call get_entity 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 retrieves data from the SQLite database without creating, modifying, or deleting any records. The use of 'Fetch' clearly indicates a read-only operation. No side effects are possible from calling this tool—it only returns existing information to the caller.
From the tool's definition Tool name 'get_entity' and description 'Fetch an entity and optionally include related metadata, content, and events' indicate a query/retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Fetch an entity and optionally include related metadata, content, and events. 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: 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 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 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. 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 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.
