Parse ASN.1 DER, BER, PEM, HEX, or base64 text and return a JSON tree.
AI agents call parse_asn1 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.
The tool only parses input data and returns a structured representation (JSON tree). It performs no writes, executions, or modifications — it is a pure read/decode operation with no side effects.

Attacks that exploit this kind of access
Parse ASN.1 DER, BER, PEM, HEX, or base64 text and return a JSON tree. 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 parse_asn1: 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.
parse_asn1 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 parse_asn1 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 parse_asn1. 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.
parse_asn1 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.
