Get the version history of an entity from your DevFlow MCP knowledge graph memory
AI agents call get_entity_history to retrieve information from DevFlow MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to retrieve version history of an entity from the knowledge graph. It retrieves or queries data without creating, modifying, deleting, or executing anything. This is a classic Read category tool with minimal blast radius if misused—an agent could retrieve sensitive historical information, but cannot alter or destroy data.
From the tool's definition Tool name 'get_entity_history' and description 'Get the version history of an entity' indicate a retrieval operation with no modification or execution of external operations. The tool queries historical data from the knowledge graph without side effects.
Attacks that exploit this kind of access
Get the version history of an entity from your DevFlow MCP knowledge graph memory. It is categorised as a Read tool in the DevFlow MCP MCP Server, which means it retrieves data without modifying state.
Register the DevFlow MCP server in PolicyLayer and add a rule for get_entity_history: 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 DevFlow MCP. Nothing to install.
get_entity_history 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_history 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_history. 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_history is provided by the DevFlow MCP server (takin-profit/devflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
