Search the iftypes.txt file for interface definitions used in the game
AI agents call search_iftypes 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 searches a static data file (iftypes.txt) to retrieve interface definitions. It is a read-only query operation with no capability to modify, delete, or execute code. The blast radius of misuse is minimal—an AI agent could retrieve interface data but cannot alter game state, execute arbitrary operations, or cause harm beyond information disclosure.
From the tool's definition Tool name 'search_iftypes' and description 'Search the iftypes.txt file for interface definitions' indicate a query operation that retrieves game data without modification or side effects.
Attacks that exploit this kind of access
Search the iftypes.txt file for interface definitions used in the game. 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_iftypes: 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_iftypes 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_iftypes 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_iftypes. 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_iftypes is provided by the OSRS MCP Server MCP server (joshhmann/mcp-osrs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
