AI agents call hotspots 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.
The tool appears to identify 'hotspots' in code (likely high-churn, high-complexity, or frequently-modified areas) based on the TempoGraph server's purpose as a code graph context engine. This is a read-only analysis operation that queries code metrics without modifying data.
From the tool's definition Tool name 'hotspots' combined with sibling tools (architecture, blast_radius, cochange_context, dead_code, dependencies, diff_context) suggests analysis/querying of code patterns.
Attacks that exploit this kind of access
hotspots. 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 hotspots: 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.
hotspots 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 hotspots 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 hotspots. 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.
hotspots 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.
