AI agents call line_length to retrieve information from Clo3d without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves a measurement (line length) from a pattern piece. It queries existing data with no side effects — purely a read/get operation. Misuse potential is minimal.
From the tool's definition Length of one outline line of a pattern piece (to match seam lengths)
Attacks that exploit this kind of access
Length of one outline line of a pattern piece (to match seam lengths). It is categorised as a Read tool in the Clo3d MCP Server, which means it retrieves data without modifying state.
Register the Clo3d MCP server in PolicyLayer and add a rule for line_length: 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 Clo3d. Nothing to install.
line_length is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the line_length 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 line_length. 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.
line_length is provided by the Clo3d MCP server (lilbonner/clo3d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
