MCPServerAdapter connects to our hosted MCP server and hands all 20 tools to your agents. Keyless, no signup.

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 18 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.

FAQs
Do I need an API key?
Do I need an API key?
No. The hosted server is keyless for read access. The hosted server runs tool calls on its own shared capacity, not on a plan of yours, so a key raises no limit there. The exceptions are the tools that need a paid plan, which run on your own Dev, Pro or Enterprise key; see the hosted server page. Limits for direct REST calls are on rate limits.
Which transport should I use?
Which transport should I use?
Use SSE (

Do I have to write any tool code?
