AI agents call overview to retrieve information from TempoGraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
In the absence of a description, the tool name 'overview' strongly suggests a read-only operation that retrieves and presents summarized information about a codebase or its architecture. No evidence of side effects, modifications, or destructive operations. The sibling tools (architecture, file_map, dependencies) reinforce this as an analytical/read-focused server.
From the tool's definition Tool named 'overview' with no description provided. Based on naming convention and context within a code graph engine (alongside tools like 'architecture', 'blast_radius', 'file_map'), this appears to be a data retrieval tool that queries or displays summary…
Attacks that exploit this kind of access
overview. It is categorised as a Read tool in the TempoGraph MCP Server, which means it retrieves data without modifying state.
Register the TempoGraph MCP server in PolicyLayer and add a rule for overview: 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 TempoGraph. Nothing to install.
overview 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 overview 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 overview. 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.
overview is provided by the TempoGraph MCP server (tempograph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
