Take a snapshot of the current terminal state. Returns the terminal content as text.
AI agents call ht_take_snapshot to retrieve information from HT 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 and returns the current state of a terminal session without creating, modifying, deleting, or executing any commands. It is a read-only operation that queries the existing state of the terminal. While the parent server enables terminal control (which could be dangerous), this specific tool merely observes and reports the terminal content without affecting it.
From the tool's definition Tool description states it 'Take[s] a snapshot of the current terminal state. Returns the terminal content as text.' The verb 'take' combined with 'returns' indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Take a snapshot of the current terminal state. Returns the terminal content as text. It is categorised as a Read tool in the HT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HT MCP Server MCP server in PolicyLayer and add a rule for ht_take_snapshot: 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 HT MCP Server. Nothing to install.
ht_take_snapshot 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 ht_take_snapshot 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 ht_take_snapshot. 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.
ht_take_snapshot is provided by the HT MCP Server MCP server (memextech/headless-terminal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
