WHAT IT DOES

What pqc_generate_keypair does on Post-Quantum Cryptography MCP Server

AI agents invoke pqc_generate_keypair to trigger actions in Post-Quantum Cryptography MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pqc_generate_keypair needs a policy

Key pair generation is an execution operation that produces cryptographic material (public/private keys). It is not a simple read, nor does it write to an external store by itself, but it triggers a cryptographic computation producing sensitive artifacts. Misuse could lead to weak key material being used or private keys being exposed/mishandled, warranting medium severity.

Verdict

pqc_generate_keypair Rate-limited

pqc_generate_keypair stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Post-Quantum Cryptography MCP Server, so you can run agents against it safely.

FAQ

Questions about pqc_generate_keypair

What does the pqc_generate_keypair tool do? +

Generate a post-quantum key pair for KEM or signature algorithm. It is categorised as a Execute tool in the Post-Quantum Cryptography MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pqc_generate_keypair? +

Register the Post-Quantum Cryptography MCP Server MCP server in PolicyLayer and add a rule for pqc_generate_keypair: 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.

What risk level is pqc_generate_keypair? +

pqc_generate_keypair is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pqc_generate_keypair? +

Yes. Add a rate_limit block to the pqc_generate_keypair 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.

How do I block pqc_generate_keypair completely? +

Set action: deny in the PolicyLayer policy for pqc_generate_keypair. 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.

What MCP server provides pqc_generate_keypair? +

pqc_generate_keypair 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.
