AI agents call crypto.dex-search to retrieve information from Mcp 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 decentralized exchange liquidity pool data without side effects. It is a pure read operation—gathering market information to help users identify pools before further action. No data is created, modified, deleted, or committed to; no code is executed; no financial transactions occur.
From the tool's definition Tool description explicitly states it 'Search[es]' and 'Returns matching pools' with liquidity data. No mention of modifying, deleting, or executing transactions.
Attacks that exploit this kind of access
Search on-chain DEX liquidity pools by token name, symbol, or address (via GeckoTerminal, free/keyless). Optionally scope to one network. Returns matching pools with pair name, USD price, FDV, market cap, reserve, 24h volume + price change, and buys/sells — the fast way to find the right pool/token before pulling OHLCV or token info. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for crypto.dex-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. Nothing to install.
crypto.dex-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 crypto.dex-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 crypto.dex-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.
crypto.dex-search is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
