Get your DevFlow MCP knowledge graph memory as it existed at a specific point in time
AI agents call get_graph_at_time 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 retrieves a snapshot of the knowledge graph at a past timestamp. It performs a read operation with no side effects—no data is created, modified, deleted, or destroyed. The temporal parameter does not change the nature of the operation from a read. The low severity reflects minimal blast radius even if invoked by an agent without direct oversight, as it only exposes existing graph data.
From the tool's definition Tool name 'get_graph_at_time' and description 'Get your DevFlow MCP knowledge graph memory as it existed at a specific point in time' indicate retrieval/querying of historical graph state with no modification or deletion.
Attacks that exploit this kind of access
Get your DevFlow MCP knowledge graph memory as it existed at a specific point in time. 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_graph_at_time: 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_graph_at_time 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_graph_at_time 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_graph_at_time. 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_graph_at_time 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.
