WHAT IT DOES

What tftp does on GNS3 MCP Server

AI agents call tftp as a supporting operation in GNS3 MCP Server workflows.

RISK

Why tftp is rated Low

TFTP (Trivial File Transfer Protocol) operations can range from reading files (GET) to writing/uploading files (PUT) to network devices. In a GNS3 context, this likely involves transferring configuration files or firmware to network nodes. Without a description, the exact capability is unknown. Given the sibling tools (node_file, http_client) and GNS3 context, this could be a Write or Execute operation.

From the tool's definition Tool name is 'tftp' but description is empty/uninformative. No description provided to clarify behavior.

RECOMMENDED RULE

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

tftp Rate-limited

tftp gets a rate cap, and everything else on the server is denied unless you say otherwise.
