Inspect a sealed or authenticated envelope
AI agents call pqc_envelope_inspect 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.
The tool performs inspection and analysis of cryptographic envelopes, which is a read-only operation that retrieves information about encrypted or authenticated data without side effects. No data is modified, deleted, or executed. This is consistent with read-category tools that query or analyze existing state.
From the tool's definition Tool name 'inspect' and description 'Inspect a sealed or authenticated envelope' indicates inspection/querying of existing cryptographic data with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Inspect a sealed or authenticated envelope. 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_envelope_inspect: 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_envelope_inspect 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_envelope_inspect 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_envelope_inspect. 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_envelope_inspect 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.
