Returns one or more named DeFi UX patterns from the Ray Group library. Patterns are recurring solutions Ray Group has seen ship well in production (or seen fail when absent). Look up a single pattern by slug, or filter by category or by the rubric area the pattern relates to.
AI agents call get_pattern to retrieve information from Ray Group DeFi UX MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that queries a glossary/library of UX patterns. It has no side effects—it only reads and returns information. There is no capability to modify data, execute code, trigger external operations, or affect financial state. The low severity reflects minimal blast radius if misused; an agent could only retrieve potentially sensitive pattern documentation or spam requests.
From the tool's definition Tool 'get_pattern' returns/retrieves data from a library ('Returns one or more named DeFi UX patterns'). No creation, modification, deletion, code execution, or financial operations are described. The verbs are query-like: 'Look up', 'filter'.
Attacks that exploit this kind of access
Returns one or more named DeFi UX patterns from the Ray Group library. Patterns are recurring solutions Ray Group has seen ship well in production (or seen fail when absent). Look up a single pattern by slug, or filter by category or by the rubric area the pattern relates to. It is categorised as a Read tool in the Ray Group DeFi UX MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ray Group DeFi UX MCP Server MCP server in PolicyLayer and add a rule for get_pattern: 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 Ray Group DeFi UX MCP Server. Nothing to install.
get_pattern 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 get_pattern 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 get_pattern. 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.
get_pattern is provided by the Ray Group DeFi UX MCP Server MCP server (raygroup/raygroup-defi-ux-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
