WHAT IT DOES

RISK

Why create_sequence_diagram is rated Medium

This tool creates (Write) a sequence diagram, which is a reversible operation that generates a visualization artifact. It does not execute code, delete data, or perform financial operations. The blast radius is minimal—worst case, a malformed diagram is created but can be discarded or overwritten. Low severity is appropriate for diagram generation.

From the tool's definition Tool name 'create_sequence_diagram' and description 'Create sequence diagram from participants and messages' indicate creation of a diagram artifact.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_sequence_diagram safely

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

create_sequence_diagram Rate-limited

create_sequence_diagram 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.
