Recommended MCP Servers
Journey fit
Canonical shelf is Build because quote aggregation plugs into product code and agent tools, not one-off market research. Integrations subphase matches wiring external liquidity and routing APIs into your app or MCP workflow.
How it compares
Quote-only finance MCP, not a full swap executor or custodial exchange integration.
