WHAT IT DOES

What feature.add does on Visionmcp

AI agents use feature.add to create or update resources in Visionmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Visionmcp environment.

RISK

Why feature.add is rated Medium

This tool creates or modifies project graph features, which is a reversible write operation. It does not execute arbitrary code, delete data, or move financial resources. The 'evidence-bound' qualifier suggests it operates within controlled constraints.

From the tool's definition Tool name 'add' and description 'Add an evidence-bound technical feature to the project graph' indicate creation/modification of project data structures.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs feature.add safely

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

feature.add Rate-limited

feature.add 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.
