AI agents call get_upload_config to retrieve information from GetNote MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves configuration metadata about upload constraints; it performs no creation, modification, deletion, or execution of commands. It is a read-only operation that queries system configuration to inform the user about upload requirements before actually uploading content. No side effects or irreversible actions occur.
From the tool's definition Tool name 'get_upload_config' and description stating it retrieves image upload configuration including supported file types and size limits.
Documented attack patterns abuse exactly the kind of access get_upload_config gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GetNote MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_upload_config:
{
"version": "1",
"default": "deny",
"tools": {
"get_upload_config": {}
}
}get_upload_config is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the GetNote MCP Server MCP server in PolicyLayer and add a rule for get_upload_config: 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 GetNote MCP Server. Nothing to install.
get_upload_config 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_upload_config 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_upload_config. 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_upload_config is provided by the GetNote MCP Server MCP server (iswalle/getnote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GetNote MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
