Read buffered output from an interactive terminal session.
AI agents call terminal-read to retrieve information from TermSSH MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves terminal output that has already been generated by prior commands. Reading buffered output is a passive operation that does not modify state, execute commands, or create side effects. It falls squarely within the Read category.
From the tool's definition Tool name 'terminal-read' and description states 'Read buffered output from an interactive terminal session.' The verb 'read' and the action of retrieving buffered output indicates data retrieval with no side effects.
Attacks that exploit this kind of access
Read buffered output from an interactive terminal session. It is categorised as a Read tool in the TermSSH MCP MCP Server, which means it retrieves data without modifying state.
Register the TermSSH MCP server in PolicyLayer and add a rule for terminal-read: 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 TermSSH MCP. Nothing to install.
terminal-read 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 terminal-read 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 terminal-read. 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.
terminal-read is provided by the TermSSH MCP server (rayss868/termssh-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
