List all Minecraft versions available in the mappings database with statistics.
AI agents call list_mapping_versions 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 tool retrieves and lists information from a mappings database. It performs a read-only operation that queries existing data and returns statistics without creating, modifying, deleting, or executing any operations. The verb 'list' combined with the informational purpose (showing available versions and statistics) confirms this is a Read category tool with minimal risk.
From the tool's definition Tool name 'list_mapping_versions' and description 'List all Minecraft versions available in the mappings database with statistics' indicate a query/retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_mapping_versions 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 list_mapping_versions:
{
"version": "1",
"default": "deny",
"tools": {
"list_mapping_versions": {}
}
}list_mapping_versions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Minecraft versions available in the mappings database with statistics. 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 list_mapping_versions: 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.
list_mapping_versions 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 list_mapping_versions 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 list_mapping_versions. 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.
list_mapping_versions 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.
