Hydrex is an Omni-Liquidity MetaDEX on Base. The plugin calls the Hydrex prepare server for quotes, portfolio state, pool data, and unsigned transaction calldata, then submits swaps and liquidity actions through Base MCP send_calls. Chain: Base mainnet. Operations: swap quotes, swaps, position reads, pool discovery, add liquidity, remove liquidity, and portfolio summaries.
On chat-only surfaces, the Hydrex prepare server may require a user-paste fallback: the assistant constructs a full GET URL, the user opens it, and the pasted JSON is mapped into send_calls.

​
Pattern

Prepare endpoints return a transactions[] array. The assistant maps every transaction into one Base MCP send_calls batch with { to, value, data } and chain: "base". Approvals and actions stay in response order so the batch executes atomically. Reads and prepare calls need the user’s wallet address as from or recipient. For liquidity actions, the assistant shows tick range, amounts, and position details before asking for approval.
