workflows · iTerm MCP: Risk & Policy

WHAT IT DOES

What workflows does on iTerm MCP

AI agents invoke workflows to trigger actions in iTerm MCP. 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 workflows needs a policy

The tool is part of an iTerm2 control system designed for 'command execution' in terminal sessions. Workflows in this context likely automate or execute terminal-based operations, which constitutes the Execute category (runs code, commands, or triggers external operations). The high severity reflects that terminal command execution has broad blast radius for system compromise, data access, or infrastructure damage.

From the tool's definition Tool named 'workflows' on iTerm MCP server that 'Controls iTerm2 terminal sessions' and allows 'parallel command execution.' The server description explicitly indicates command execution capabilities via terminal sessions.

Verdict

workflows Rate-limited

workflows 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 iTerm MCP, so you can run agents against it safely.

FAQ

Questions about workflows

What does the workflows tool do? +

workflows. It is categorised as a Execute tool in the iTerm MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on workflows? +

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

What risk level is workflows? +

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

Can I rate-limit workflows? +

Yes. Add a rate_limit block to the workflows 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 workflows completely? +

Set action: deny in the PolicyLayer policy for workflows. 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 workflows? +

workflows is provided by the iTerm MCP server (research-developer/iterm-mcp-claude-agency). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
