Rank PKI ASN.1 definition candidates using the built-in ASN.1 Definition Sifter PKI corpus and optional profile filters.
AI agents call sift_pki_asn1_definition_candidates to retrieve information from PKI Studio MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and ranks candidate ASN.1 definitions from a predefined corpus using profile filters. It is a query/search operation that returns ranked results without creating, modifying, deleting, or executing code. The operation is entirely read-only with no side effects on system state.

Rank PKI ASN.1 definition candidates using the built-in ASN.1 Definition Sifter PKI corpus and optional profile filters. It is categorised as a Read tool in the PKI Studio MCP MCP Server, which means it retrieves data without modifying state.
Register the PKI Studio MCP server in PolicyLayer and add a rule for sift_pki_asn1_definition_candidates: 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 PKI Studio MCP. Nothing to install.
sift_pki_asn1_definition_candidates 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 sift_pki_asn1_definition_candidates 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 sift_pki_asn1_definition_candidates. 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.
sift_pki_asn1_definition_candidates is provided by the PKI Studio MCP server (pkistudio/pkistudiomcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
