dna · MCP Document Processor MCP: Risk & Policy

WHAT IT DOES

What dna does on MCP Document Processor

AI agents call dna as a supporting operation in MCP Document Processor workflows.

WHY IT NEEDS A POLICY

Why dna needs a policy

The description 'Manage the project' is too ambiguous to confidently assign a specific risk category. Given the server context (document processor), it may relate to project metadata management, but there is no evidence of reading, writing, executing, destructive, or financial operations. Confidence is very low due to the uninformative description.

From the tool's definition Tool name 'dna' and description 'Manage the project' are both vague and uninformative; no specific action or data type is described.
