AI agents use create_flowchart to create or update resources in Claude Patent Creator — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Patent Creator environment.
The tool appears to create flowchart diagrams as part of patent documentation workflows. This is a Write action—it generates new content (flowcharts) that can be modified or deleted reversibly. Severity is medium because misuse could create misleading patent diagrams, but the impact is contained to document creation without direct financial, destructive, or execution consequences.
From the tool's definition Tool name 'create_flowchart' and server context ('patent creation and analysis') indicate document generation. Sibling tool 'create_block_diagram' suggests this creates visual artifacts. Empty description limits certainty.
Documented attack patterns abuse exactly the kind of access create_flowchart gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Patent Creator, and nothing reaches the server without passing your rules. This is the rule we recommend for create_flowchart:
{
"version": "1",
"default": "deny",
"tools": {
"create_flowchart": {
"limits": [
{
"counter": "create_flowchart_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_flowchart 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.

create_flowchart. It is categorised as a Write tool in the Claude Patent Creator MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Claude Patent Creator MCP server in PolicyLayer and add a rule for create_flowchart: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claude Patent Creator. Nothing to install.
create_flowchart is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_flowchart rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_flowchart. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_flowchart is provided by the Claude Patent Creator MCP server (robthepcguy/claude-patent-creator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
