AI agents call get_sections to retrieve information from Overleaf MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves section information from a LaTeX document. It performs a read-only operation that extracts structural data without creating, modifying, deleting, or executing any code. The action is informational and has no side effects on the document or system.
From the tool's definition Tool name 'get_sections' and description 'Get all sections from a LaTeX file' indicate retrieval of document structure metadata without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_sections gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Overleaf MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_sections:
{
"version": "1",
"default": "deny",
"tools": {
"get_sections": {}
}
}get_sections is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all sections from a LaTeX file. It is categorised as a Read tool in the Overleaf MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Overleaf MCP Server MCP server in PolicyLayer and add a rule for get_sections: 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 Overleaf MCP Server. Nothing to install.
get_sections is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_sections 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 get_sections. 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.
get_sections is provided by the Overleaf MCP Server MCP server (mjyoo2/overleafmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Overleaf MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
