AI agents call rpki_validate to retrieve information from Net without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
RPKI validation is fundamentally a read operation that checks cryptographic signatures and origin assertions against public databases. It retrieves and verifies data without side effects. The tool description is empty, which slightly reduces confidence, but the name combined with the server's stated purpose (validation against public data) strongly indicates a read-only diagnostic function.
From the tool's definition Tool name 'rpki_validate' indicates validation/checking of RPKI (Resource Public Key Infrastructure) data.
Attacks that exploit this kind of access
rpki_validate. It is categorised as a Read tool in the Net MCP Server, which means it retrieves data without modifying state.
Register the Net MCP server in PolicyLayer and add a rule for rpki_validate: 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 Net. Nothing to install.
rpki_validate 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 rpki_validate 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 rpki_validate. 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.
rpki_validate is provided by the Net MCP server (steelcutoatmeal/net-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
