Search Minecraft class, method, and field mappings from Parchment data. Returns deobfuscated names, parameter names, and Javadoc documentation. Use this when you need to understand Minecraft internals or find the correct class/method names for modding.
AI agents call search_mappings 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.
search_mappings is a query/lookup tool that retrieves and presents Minecraft mapping documentation. It performs no data modification, deletion, code execution, or financial operations. The worst case misuse would be an AI agent wasting API calls or retrieving irrelevant documentation, which poses minimal risk. This is a standard Read operation.
From the tool's definition Tool description explicitly states it 'Search[es]' and 'Returns' mapping data. The verbs 'search' and 'return' indicate data retrieval with no modification.
Documented attack patterns abuse exactly the kind of access search_mappings 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 search_mappings:
{
"version": "1",
"default": "deny",
"tools": {
"search_mappings": {}
}
}search_mappings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search Minecraft class, method, and field mappings from Parchment data. Returns deobfuscated names, parameter names, and Javadoc documentation. Use this when you need to understand Minecraft internals or find the correct class/method names for modding. 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 search_mappings: 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.
search_mappings 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 search_mappings 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 search_mappings. 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.
search_mappings 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.
