switch_pane

Switches to a specific pane in WezTerm

Single-target operation

Part of the WezTerm MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use switch_pane to create or modify resources in WezTerm MCP Server. 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 switch_pane repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach WezTerm MCP Server.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the switch_pane tool do? +

Switches to a specific pane in WezTerm. It is categorised as a Write tool in the WezTerm MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on switch_pane? +

Add a rule in your Intercept YAML policy under the tools section for switch_pane. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the WezTerm MCP Server MCP server.

What risk level is switch_pane? +

switch_pane is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit switch_pane? +

Yes. Add a rate_limit block to the switch_pane rule in your Intercept 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.

How do I block switch_pane completely? +

Set action: deny in the Intercept policy for switch_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.

What MCP server provides switch_pane? +

switch_pane is provided by the WezTerm MCP Server MCP server (hiraishikentaro/wezterm-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
