What notification does on GNS3 MCP Server
AI agents call notification 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.
Why notification is rated Low
Without description details, classification is uncertain. The name 'notification' most likely indicates reading/retrieving notification data from GNS3, which would be a Read operation with low blast radius. However, confidence is reduced due to lack of concrete evidence in the description. If the tool actually modifies notification state or triggers actions, recategorization would be warranted.
From the tool's definition Tool name 'notification' with empty description provides minimal context. The name suggests retrieval or monitoring of notifications rather than state-changing operations.
Attacks that exploit this kind of access
The rule that runs notification 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 notification, this is the rule to start with:
notification is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GNS3 MCP Server, apply this rule, and every notification call is checked against it from then on.
Questions about notification
notification is a read tool on the GNS3 MCP Server MCP server. It is categorised as a Read tool in the GNS3 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GNS3 MCP Server MCP server in PolicyLayer and add a rule for notification: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GNS3 MCP Server. Nothing to install.
notification is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the notification rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for notification. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
notification is provided by the GNS3 MCP Server MCP server (chistokhinsv/gns3-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
