extract_table
AI agents call extract_table to retrieve information from TmuxControlLib MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the name 'extract_table' combined with the context of similar read-focused tools (capture_*, get_*, find_text) indicates this retrieves or parses structured data from terminal output without modifying any state. The tool belongs in the Read category with low severity since extraction operations have no side effects.

extract_table. It is categorised as a Read tool in the TmuxControlLib MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TmuxControlLib MCP Server MCP server in PolicyLayer and add a rule for extract_table: 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 TmuxControlLib MCP Server. Nothing to install.
extract_table 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 extract_table 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 extract_table. 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.
extract_table is provided by the TmuxControlLib MCP Server MCP server (jbwinters/tmuxcontrollib). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
