Search the seqtypes.txt file for animation sequence definitions.
AI agents call search_seqtypes 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 animation sequence data from a static game data file. It performs a read-only search operation similar to other sibling tools like 'osrs_wiki_search' and 'search_data_file'. There are no side effects, data modifications, code execution, deletions, or financial implications. The severity is low because misuse would only expose read-only gaming data with no harmful consequences.
From the tool's definition Tool name 'search_seqtypes' and description 'Search the seqtypes.txt file for animation sequence definitions' indicate a query/search operation against a game data file with no modification, deletion, or execution capabilities.
Documented attack patterns abuse exactly the kind of access search_seqtypes 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_seqtypes:
{
"version": "1",
"default": "deny",
"tools": {
"search_seqtypes": {}
}
}search_seqtypes 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 seqtypes.txt file for animation sequence 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_seqtypes: 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_seqtypes 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_seqtypes 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_seqtypes. 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_seqtypes 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.
