Limitations

  • The server does not start without its environment variables set, not even to list its tools.
  • Hosted calls with a test key are not available: the runtime has not recorded this provider's test behaviour (test venue unclassified).

Tools

What your agent can call.

4 tools, as the package's tools/list returns them.

create_payment

Create an onchain payment (outbound transfer to a payee). Returns the payment id and initial status. Endpoint set provisional.

list_payments

List historical payments under the authenticated CDP account. Cursor-paginated. Endpoint set provisional.

get_payment

Get a single payment by id — full status, tx hash, gas. Endpoint set provisional.

cancel_payment

Cancel a pending payment before it lands onchain. Endpoint set provisional.

Names and descriptions come from the package's tools/list (@codespar/mcp-coinbase-cdp@0.1.1). A kind (read, write, delete) is shown only when the package annotates its tools or each tool was verified one by one; neither exists for this server yet.

Compatibility

MCP is a protocol. Any client that speaks it can mount this server.

codespar_discover lists this server's tools, but a project with a test key cannot call them yet: the runtime has not recorded what this provider does in test mode, and refuses rather than guess.
