ttya_start · Networkselfmd MCP: Risk & Policy

WHAT IT DOES

What ttya_start does on Networkselfmd

AI agents invoke ttya_start to trigger actions in Networkselfmd. 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.

WHY IT NEEDS A POLICY

Why ttya_start needs a policy

Starting a web server is an Execute action—it runs a process and initiates external operations (listening on ports, accepting connections, exposing endpoints). While not destructive or financial, it can impact system state and network exposure.

From the tool's definition Tool name 'ttya_start' and description 'Start the TTYA web server' indicate execution of a server process.

Verdict

ttya_start Rate-limited

ttya_start stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Networkselfmd, so you can run agents against it safely.

FAQ

Questions about ttya_start

What does the ttya_start tool do? +

Start the TTYA web server for visitor interactions (not yet implemented). It is categorised as a Execute tool in the Networkselfmd MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on ttya_start? +

Register the Networkselfmd MCP server in PolicyLayer and add a rule for ttya_start: 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 Networkselfmd. Nothing to install.

What risk level is ttya_start? +

ttya_start is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit ttya_start? +

Yes. Add a rate_limit block to the ttya_start 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.

How do I block ttya_start completely? +

Set action: deny in the PolicyLayer policy for ttya_start. 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.

What MCP server provides ttya_start? +

ttya_start is provided by the Networkselfmd MCP server (selfmd/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
