Get ticker information for multiple instruments at once. More efficient than get_ticker when querying many instruments.
AI agents call get_tickers to retrieve information from Derive MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves real-time market data (ticker information) for multiple trading instruments. It performs no writes, executions, deletions, or financial transactions—it only queries and returns data. The blast radius of misuse is minimal since viewing market data cannot cause direct harm. Severity is low because ticker data is typically public and reading it carries no operational risk.
From the tool's definition Tool name 'get_tickers' and description 'Get ticker information for multiple instruments at once' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Get ticker information for multiple instruments at once. More efficient than get_ticker when querying many instruments. It is categorised as a Read tool in the Derive MCP MCP Server, which means it retrieves data without modifying state.
Register the Derive MCP server in PolicyLayer and add a rule for get_tickers: 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 Derive MCP. Nothing to install.
get_tickers 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_tickers 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_tickers. 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_tickers is provided by the Derive MCP server (solenyaresearch0000/derive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
