WHAT IT DOES

What open_presentation does on ContextForge MCP Gateway

AI agents call open_presentation to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why open_presentation is rated Low

The tool opens (reads) an existing file. 'Open' in the context of a presentation implies loading/reading the file into memory, not modifying or deleting it. No destructive or write side effects are indicated. Severity is low as it only accesses a local file.

RECOMMENDED RULE

The rule that runs open_presentation 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 open_presentation, this is the rule to start with:

open_presentation Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "open_presentation": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every open_presentation call is checked against it from then on.
