Search for information
AI agents call search to retrieve information from MCP Binance 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 cryptocurrency market data from Binance (prices, rates, open interest) with no side effects. Even if search results inform trading decisions, the tool itself only reads data. No write, destructive, financial transaction, or code execution capability is evident.
From the tool's definition Tool name 'search' and description 'Search for information' indicate data retrieval. Context shows server provides 'fetch real-time cryptocurrency market data' with no mention of order placement, fund transfers, or destructive operations.

Search for information. It is categorised as a Read tool in the MCP Binance MCP Server, which means it retrieves data without modifying state.
Register the MCP Binance MCP server in PolicyLayer and add a rule for search: 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 MCP Binance. Nothing to install.
search 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 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. 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 is provided by the MCP Binance MCP server (shukehi/crypto-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
