Install
Coinbase publishes no copyable client config for this server. Point your MCP client at https://api.cdp.coinbase.com/platform/v2/x402/discovery/mcp. Setup steps are in the vendor's docs.
Tools
search_resources- Semantic search over the Bazaar catalog of x402 services.
proxy_tool_call- Call a discovered resource by toolName and arguments; paid resources return a payment-required result.
validate_endpoint- Read-only diagnostics for an x402 URL (reachability, 402 response, discovery block).
As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- Discovery is public and unauthenticated; no CDP API key is needed to connect or search.
- Paying requires an x402-capable client (for example @x402/mcp wrapMCPClientWithPayment with a CDP-managed wallet via @coinbase/cdp-sdk).
- The docs do not state the transport and give no client config snippet.
- AWS Bedrock AgentCore offers a Gateway target for this endpoint.
