WHAT IT DOES

What fork_agent_character does on FlowDot MCP Server

AI agents use fork_agent_character to create or update resources in FlowDot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FlowDot MCP Server environment.

RISK

Why fork_agent_character is rated Medium

This tool creates a new copy of a public agent character in the user's library. It is a reversible write operation (creating a new resource), not destructive, not financial, and not executing arbitrary code. The blast radius is low as it only adds a derived resource to the user's own library.

From the tool's definition Fork a public agent character to your library by hash. Voice config + persona are copied; the LLM choice is reset so you pick your own.

RECOMMENDED RULE

The rule that runs fork_agent_character safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FlowDot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fork_agent_character, this is the rule to start with:

fork_agent_character Rate-limited

fork_agent_character 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.
