Resizes a terminal to the specified dimensions in columns × rows.
AI agents use mcpretentious-resize to create or update resources in MCPretentious — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCPretentious environment.
This tool modifies the terminal window dimensions, which is a reversible configuration change. It doesn't execute commands, delete data, or have financial implications. The blast radius is low since resizing a terminal is easily undone and has minimal impact beyond cosmetic/usability effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCPretentious, and nothing reaches the server without passing your rules. This is the rule we recommend for mcpretentious-resize:
{
"version": "1",
"default": "deny",
"tools": {
"mcpretentious-resize": {
"limits": [
{
"counter": "mcpretentious-resize_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}mcpretentious-resize stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
