WHAT IT DOES

What search_tools does on GNS3 MCP Server

AI agents call search_tools to retrieve information from GNS3 MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_tools is rated Low

The name indicates this tool searches available tools or documentation, which is a read-only operation with no side effects. However, confidence is reduced due to the empty description, which prevents full verification of its actual behavior and scope. Within the context of a GNS3 lab automation server, a search function would likely be informational rather than operationally impactful.

From the tool's definition Tool name 'search_tools' and the absence of any description suggesting data retrieval or discovery functionality.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_tools safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GNS3 MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_tools, this is the rule to start with:

search_tools Allowed

search_tools 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": {
    "search_tools": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect GNS3 MCP Server, apply this rule, and every search_tools call is checked against it from then on.
