What layout does on TeXFlow
AI agents use layout to create or update resources in TeXFlow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TeXFlow environment.
Why layout is rated Medium
Given the context of a collaborative document authoring system, 'layout' most likely modifies document structure, styling, or page formatting—reversible operations characteristic of Write category. Without an explicit description, confidence is reduced. It does not appear to delete data (Destructive), execute arbitrary code (Execute), or handle financial operations (Financial).
From the tool's definition Tool named 'layout' on a document authoring server (TeXFlow) with sibling tools including 'document', 'edit', 'render'. The name 'layout' suggests modifying document structure or formatting, which constitutes content modification.
Attacks that exploit this kind of access
The rule that runs layout safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TeXFlow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For layout, this is the rule to start with:
layout stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TeXFlow, apply this rule, and every layout call is checked against it from then on.
Questions about layout
layout is a write tool on the TeXFlow MCP server. It is categorised as a Write tool in the TeXFlow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the TeXFlow MCP server in PolicyLayer and add a rule for layout: 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 TeXFlow. Nothing to install.
layout is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the layout 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 layout. 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.
layout is provided by the TeXFlow MCP server (aaronsb/texflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
