AI agents call ai_analyze_vcon to retrieve information from Vcon without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though ai_analyze_vcon only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Run AI analysis (sentiment, summary, topics) on a specific vCon by UUID. Useful for re-analyzing or analyzing vCons that were created before the AI sidecar was available. It is categorised as a Read tool in the Vcon MCP Server, which means it retrieves data without modifying state.
Register the Vcon MCP server in PolicyLayer and add a rule for ai_analyze_vcon: 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 Vcon. Nothing to install.
ai_analyze_vcon 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 ai_analyze_vcon 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 ai_analyze_vcon. 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.
ai_analyze_vcon is provided by the Vcon MCP server (vcon-dev/vcon-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
