Search the rowtypes.txt file for row definitions used in various interfaces.
AI agents call search_rowtypes 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 or queries data from a game definition file (rowtypes.txt) without creating, modifying, deleting, or executing any operations. It is a straightforward data lookup function consistent with sibling tools like search_npctypes, search_invtypes, and osrs_wiki_search. There are no side effects, no code execution, and no destructive or financial implications.
From the tool's definition Tool is named 'search_rowtypes' and described as 'Search the rowtypes.txt file for row definitions'. The verb 'search' and the read-only nature of querying a static data file indicate retrieval without modification.
Attacks that exploit this kind of access
Search the rowtypes.txt file for row definitions used in various interfaces. 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_rowtypes: 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_rowtypes 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_rowtypes 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_rowtypes. 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_rowtypes 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.
