WHAT IT DOES

What add_slide does on ContextForge MCP Gateway

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

RISK

Why add_slide is rated Medium

This tool creates new presentation slides, which is a reversible write operation. It modifies a presentation document by adding content but does not execute arbitrary code, delete data, or move money. The blast radius is minimal—a mistaken slide addition can be easily undone. Confidence is high given the clear semantics of 'add' and 'slide' in a presentation context.

From the tool's definition Tool name 'add_slide' and description 'Add a new slide to the presentation' indicate creation of new content within a presentation document.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_slide safely

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

add_slide Rate-limited

add_slide 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.
