Capture and return the visible text content of a tmux pane.
AI agents call capture_pane to retrieve information from Post-Exploitation tmux MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and returns existing pane content without creating, modifying, deleting, or executing operations. It has no side effects and poses minimal risk if misused—an AI could at worst view terminal output, which is a read-only operation.
From the tool's definition Tool name 'capture_pane' and description 'Capture and return the visible text content of a tmux pane' indicate retrieval of display data with no modification or execution.

Register the Post-Exploitation tmux MCP Server MCP server in PolicyLayer and add a rule for capture_pane: 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-Exploitation tmux MCP Server. Nothing to install.
capture_pane 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 capture_pane 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 capture_pane. 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.
capture_pane is provided by the Post-Exploitation tmux MCP Server MCP server (raghavansv/tmux-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
