AI agents invoke test_sftp_connection to trigger actions in AdButler. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
host | string | — | SFTP host |
path | string | — | Remote path |
port | number | — | SFTP port |
password | string | — | SFTP password |
username | string | — | SFTP username |
Parameters from the server's own tool schema.
This tool actively initiates a network connection to an external SFTP server using provided credentials. It executes an external operation (connection attempt) rather than merely reading or writing data. Misuse could expose credentials, probe external systems, or be used for reconnaissance. Severity is medium as it doesn't modify data but does trigger real external network operations.

Attacks that exploit this kind of access
Test an SFTP connection with the provided credentials. It is categorised as a Execute tool in the AdButler MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
test_sftp_connection accepts 5 parameters: host, path, port, password, username. The full parameter table on this page comes from the server's own tool schema.
Register the AdButler MCP server in PolicyLayer and add a rule for test_sftp_connection: 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 AdButler. Nothing to install.
test_sftp_connection is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the test_sftp_connection 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 test_sftp_connection. 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.
test_sftp_connection is provided by the AdButler MCP server (adbutler/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
