Verify a span-level AssetRef against the persisted citation index.
AI agents call verify_citation_ref to retrieve information from Asset Aware without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a verification or validation query against a citation index. The operation is read-only—it retrieves and checks information without creating, modifying, or deleting any data. There are no side effects or irreversible actions. The blast radius of misuse is minimal since the tool only returns verification results about existing citations.
From the tool's definition Tool name 'verify_citation_ref' and description 'Verify a span-level AssetRef against the persisted citation index' indicate a lookup/verification operation that checks citation references against an existing index without modifying data.
Attacks that exploit this kind of access
Verify a span-level AssetRef against the persisted citation index. It is categorised as a Read tool in the Asset Aware MCP Server, which means it retrieves data without modifying state.
Register the Asset Aware MCP server in PolicyLayer and add a rule for verify_citation_ref: 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 Asset Aware. Nothing to install.
verify_citation_ref 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 verify_citation_ref 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 verify_citation_ref. 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.
verify_citation_ref is provided by the Asset Aware MCP server (u9401066/asset-aware-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
