List WebCrypto key pair algorithms supported by this runtime for key generation.
AI agents call list_supported_key_algorithms 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 displays a static list of supported cryptographic algorithms. It has no side effects, does not modify data, does not execute arbitrary operations, and does not create, delete, or transfer resources. It is purely informational, making it a Read category risk with low severity.
From the tool's definition Tool name 'list_supported_key_algorithms' and description 'List WebCrypto key pair algorithms supported by this runtime for key generation' indicate a read-only query that retrieves supported algorithm information without modifying state or executing code.
Attacks that exploit this kind of access
List WebCrypto key pair algorithms supported by this runtime for key generation. 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 list_supported_key_algorithms: 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.
list_supported_key_algorithms 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 list_supported_key_algorithms 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 list_supported_key_algorithms. 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.
list_supported_key_algorithms 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.
