List all available post-quantum cryptographic algorithms (KEMs and signatures)
AI agents call pqc_list_algorithms to retrieve information from Post-Quantum Cryptography MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates information about available cryptographic algorithms without modifying any data, executing code, or causing any external effects. It is purely informational and carries minimal risk even if misused by an AI agent, as it only exposes algorithm names and properties rather than performing cryptographic operations or accessing sensitive material.
From the tool's definition Tool name 'pqc_list_algorithms' and description 'List all available post-quantum cryptographic algorithms' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List all available post-quantum cryptographic algorithms (KEMs and signatures). It is categorised as a Read tool in the Post-Quantum Cryptography MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Post-Quantum Cryptography MCP Server MCP server in PolicyLayer and add a rule for pqc_list_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 Post-Quantum Cryptography MCP Server. Nothing to install.
pqc_list_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 pqc_list_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 pqc_list_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.
pqc_list_algorithms is provided by the Post-Quantum Cryptography MCP Server MCP server (scottdhughes/post-quantum-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
