Get the template format of a Flyte script.
AI agents call flyte_uv_script_format to retrieve information from Union MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns template/format information about Flyte scripts—a pure data retrieval operation with no side effects. It does not execute code, modify data, delete resources, or commit financial transactions. The verb 'Get' combined with 'template format' indicates a read-only query operation.
From the tool's definition Tool name contains 'get' semantics ("Get the template format") and the description explicitly states it retrieves a template format with no indication of modification, deletion, or execution of scripts.

PolicyLayer is an MCP gateway — it sits between your AI agents and Union MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for flyte_uv_script_format:
{
"version": "1",
"default": "deny",
"tools": {
"flyte_uv_script_format": {}
}

flyte_uv_script_format is provided by the Union MCP server (unionai-oss/union-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Union MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
