Search the spottypes.txt file for spot animation (graphical effect) definitions.
AI agents call search_spottypes to retrieve information from OSRS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries graphical effect definitions from a game data file. It has no side effects, does not modify data, execute code, or affect game state. It is a straightforward read operation consistent with other lookup tools on this OSRS Wiki/data server (search_data_file, osrs_wiki_search, lookup_player).
From the tool's definition Tool name 'search_spottypes' and description indicate it searches a data file for spot animation definitions. The verb 'search' combined with 'definitions' indicates read-only data retrieval with no modification, creation, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access search_spottypes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OSRS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_spottypes:
{
"version": "1",
"default": "deny",
"tools": {
"search_spottypes": {}
}
}search_spottypes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Search the spottypes.txt file for spot animation (graphical effect) definitions. It is categorised as a Read tool in the OSRS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OSRS MCP Server MCP server in PolicyLayer and add a rule for search_spottypes: 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 OSRS MCP Server. Nothing to install.
search_spottypes 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_spottypes 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_spottypes. 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_spottypes is provided by the OSRS MCP Server MCP server (jayarrowz/mcp-osrs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OSRS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
