Browse classes in a specific Minecraft package. Useful for discovering available classes in a package.
AI agents call browse_package to retrieve information from Mcmodding without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation: it retrieves data about package contents without side effects. Severity is elevated to 'high' (not 'medium') because an AI agent with access to complete package/class discovery could systematically enumerate the entire Minecraft modding surface, map internal APIs, identify security-relevant classes, or discover undocumented capabilities that could support downstream exploitation or…
From the tool's definition Tool 'browse_package' retrieves and queries class information from Minecraft packages ('Browse classes in a specific Minecraft package').
Documented attack patterns abuse exactly the kind of access browse_package gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcmodding, and nothing reaches the server without passing your rules. This is the rule we recommend for browse_package:
{
"version": "1",
"default": "deny",
"tools": {
"browse_package": {}
}
}browse_package is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Browse classes in a specific Minecraft package. Useful for discovering available classes in a package. It is categorised as a Read tool in the Mcmodding MCP Server, which means it retrieves data without modifying state.
Register the Mcmodding MCP server in PolicyLayer and add a rule for browse_package: 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 Mcmodding. Nothing to install.
browse_package 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 browse_package 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 browse_package. 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.
browse_package is provided by the Mcmodding MCP server (ogmatrix/mcmodding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
