AI agents use create_latex_file to create or update resources in MCP LaTeX Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP LaTeX Server environment.
Creating LaTeX files is a write operation that modifies the filesystem by adding new documents. This is reversible (files can be deleted) but represents a side effect that changes system state. Severity is medium because while file creation itself is low-risk, an AI agent could create numerous files consuming disk space or create files with malicious LaTeX content (though LaTeX execution is typically sandboxed).
From the tool's definition Tool name 'create_latex_file' indicates creation of new files. Server description states it 'Enables AI assistants to create, edit, and validate LaTeX documents' and 'provides tools for...file organization.' The tool name and server context clearly show file…
Documented attack patterns abuse exactly the kind of access create_latex_file gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP LaTeX Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_latex_file:
{
"version": "1",
"default": "deny",
"tools": {
"create_latex_file": {
"limits": [
{
"counter": "create_latex_file_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_latex_file 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.

create_latex_file. It is categorised as a Write tool in the MCP LaTeX Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP LaTeX Server MCP server in PolicyLayer and add a rule for create_latex_file: 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 MCP LaTeX Server. Nothing to install.
create_latex_file 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 create_latex_file 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 create_latex_file. 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.
create_latex_file is provided by the MCP LaTeX Server MCP server (robertodure/mcp-latex-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP LaTeX Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
