WHAT IT DOES

What extract_drawing_constraints does on Pypi:best Cad

AI agents call extract_drawing_constraints to retrieve information from Pypi:best Cad without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why extract_drawing_constraints is rated Low

This tool queries a CAD drawing to retrieve dimension and constraint information and places it into a database. While it writes to the SQLite database, the primary action is reading/extracting data from the source drawing. The write operation is only to store the extracted data in a new location without altering the original drawing.

From the tool's definition The tool description states it 'Extract[s]... constraints into SQLite'—extraction is a read operation that retrieves data from a drawing without modifying it. The verb 'extract' indicates data retrieval, not creation, modification, or deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs extract_drawing_constraints safely

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

extract_drawing_constraints Allowed

extract_drawing_constraints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
