WHAT IT DOES

What improve_prompt does on MCP Framework Personal

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

RISK

Why improve_prompt is rated Medium

With an empty description, confidence is low. Based on the name alone, 'improve_prompt' likely modifies or rewrites a prompt string, which falls under Write (reversible modification). It does not strongly suggest execution, destruction, or financial operations. Severity is medium because prompt manipulation could influence AI behavior if misused, but the blast radius is limited without more context.

From the tool's definition Tool name 'improve_prompt' with empty description. The name suggests modifying or enhancing a prompt.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs improve_prompt safely

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

improve_prompt Rate-limited

improve_prompt 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.
