Connect the hosted MCP server
MCPServerAdapter pulls the tools from https://mcp.dexpaprika.com/sse and exposes them as native CrewAI tools:
with block keeps the MCP connection open for the crew’s run and closes it afterward. Use the /sse transport; it is the tested default.
Tools and the rationale field
All 17 DexPaprika tools appear as CrewAI tools: networks, pools, tokens, OHLCV, transactions, and cross-chain search. See the MCP tools reference for the full list. Every read tool takes a requiredrationale string (1-2 sentences on why you are calling it). It is part of each tool’s schema, so a capable model fills it automatically. If a smaller model returns validation errors, prompt it to include a short rationale.
