WHAT IT DOES

What list_authors does on ContextForge MCP Gateway

AI agents call list_authors 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 list_authors is rated Low

This tool retrieves and lists existing author/speaker data with counts. The verb 'list' and the passive nature of the operation (no creation, modification, deletion, or execution) clearly place this in the Read category. The blast radius is minimal since it only exposes informational metadata about authors. Severity is low as unauthorized access would reveal only non-sensitive enumeration data.

From the tool's definition Tool name 'list_authors' and description 'List all unique authors/speakers with entry counts' indicate a retrieval operation that queries and returns metadata without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_authors Allowed

list_authors 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": {
    "list_authors": {}
  }
}

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 list_authors call is checked against it from then on.
