What tls_keylog_seal does on Jshookmcp
AI agents call tls_keylog_seal to permanently remove resources in Jshookmcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why tls_keylog_seal is rated Critical
Irreversibly modifies sensitive security material; data unrecoverable without retained key.
From the tool's definition Encrypt in place, securely wipe plaintext source, unrecoverable.
Attacks that exploit this kind of access
The rule that runs tls_keylog_seal safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tls_keylog_seal, this is the rule to start with:
tls_keylog_seal is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every tls_keylog_seal call is checked against it from then on.
Questions about tls_keylog_seal
Encrypt the current keylog file in place with a fresh ephemeral key and securely wipe the plaintext source. Mitigates disk-forensics exposure (pagefile/hibernation/TEMP scraping) of captured TLS secrets. The returned keyHex is not persisted anywhere — hold onto it to decrypt the sealed envelope later, or it is unrecoverable once the process exits. It is categorised as a Destructive tool in the Jshookmcp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Jshook MCP server in PolicyLayer and add a rule for tls_keylog_seal: 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 Jshookmcp. Nothing to install.
tls_keylog_seal is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the tls_keylog_seal 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 tls_keylog_seal. 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.
tls_keylog_seal is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
