Fast full-text search using pre-built mod index. Much faster than search_mod_code for large queries. Requires index_mod first. Supports FTS5 syntax: AND, OR, NOT,
AI agents call search_mod_indexed to retrieve information from Minecraft Dev MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
search_mod_indexed retrieves and queries data from an indexed mod database without creating, modifying, deleting, or executing operations. The search functionality is purely informational and read-only in nature.
From the tool's definition Tool description indicates it performs "full-text search using pre-built mod index" with support for query operators (AND, OR, NOT). This is explicitly a search/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access search_mod_indexed gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Minecraft Dev MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_mod_indexed:
{
"version": "1",
"default": "deny",
"tools": {
"search_mod_indexed": {}
}
} search_mod_indexed is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fast full-text search using pre-built mod index. Much faster than search_mod_code for large queries. Requires index_mod first. Supports FTS5 syntax: AND, OR, NOT,. It is categorised as a Read tool in the Minecraft Dev MCP MCP Server, which means it retrieves data without modifying state.
Register the Minecraft Dev MCP server in PolicyLayer and add a rule for search_mod_indexed: 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 Minecraft Dev MCP. Nothing to install.
search_mod_indexed 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_mod_indexed 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_mod_indexed. 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_mod_indexed is provided by the Minecraft Dev MCP server (mcdxai/minecraft-dev-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Minecraft Dev MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
