Send a command/input to an interactive session and wait for output. Appends newline automatically. Returns clean text output (no ANSI codes). If a dangerous command is detected, you must use confirm_dangerous_command first.

AI agents use send_command to create or modify resources in Mcp Interactive Terminal. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call send_command repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Interactive Terminal.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access send_command gives an agent. Each links to the full case and the policy that stops it:

Send a command/input to an interactive session and wait for output. Appends newline automatically. Returns clean text output (no ANSI codes). If a dangerous command is detected, you must use confirm_dangerous_command first.. It is categorised as a Write tool in the Mcp Interactive Terminal MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Interactive Terminal MCP server in PolicyLayer and add a rule for send_command: 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 Mcp Interactive Terminal. Nothing to install.
send_command is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the send_command 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 send_command. 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.
send_command is provided by the Mcp Interactive Terminal MCP server (mcp-interactive-terminal). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
