@codespar/mcp-coinbase-cdp

MCP server for the Coinbase Developer Platform (CDP) — single npm package covering three CDP product surfaces under one key:

  • Trading — onchain swap / trade API
  • Wallets — Smart / Embedded / MPC wallet primitives
  • Payments — onchain outbound payment infrastructure

All three live on the same CDP account, share one ES256 JWT-signed key, and share one base URL (https://api.cdp.coinbase.com) — so they ship as one package, not three.

Positioning vs the rest of the catalog

Server Coinbase surface Auth
@codespar/mcp-coinbase Advanced Trade exchange (legacy retail) HMAC API keys (CB-ACCESS-*)
@codespar/mcp-coinbase-commerce Commerce merchant gateway (accept BTC/ETH/USDC at checkout) API key (X-CC-Api-Key)
@codespar/mcp-coinbase-cdp Developer Platform (Trading + Wallets + Payments) ES256 JWT (this package)

Each surface has a separate API host, a separate key type, and a separate dashboard — they do not share credentials. Mint the right key for the surface you want.

Install

npm install -g @codespar/mcp-coinbase-cdp

Environment

COINBASE_CDP_KEY_NAME="organizations/<org>/apiKeys/<id>"
COINBASE_CDP_PRIVATE_KEY="-----BEGIN EC PRIVATE KEY-----
...
-----END EC PRIVATE KEY-----"

Mint the key (and download the PEM once — it is not recoverable later) at https://portal.cdp.coinbase.com. The same key authenticates Trading, Wallets, and Payments.

Important — the PEM must be the full multi-line block including BEGIN/END lines. When supplying via shell env, wrap in double quotes and preserve newlines (or use $'...' / a .env file).

Authentication

CDP signs every request with a fresh ES256 JWT in the Authorization: Bearer … header.

JWT claims (per request):

Claim Value
sub COINBASE_CDP_KEY_NAME
iss "cdp"
aud ["cdp_service"]
nbf now (unix seconds)
exp now + 120
uri "<METHOD> api.cdp.coinbase.com<path>" (path includes any query string)

JWT header:

Field Value
alg "ES256"
typ "JWT"
kid COINBASE_CDP_KEY_NAME
nonce random 16-byte hex (per request)

Signed with the ECDSA P-256 private key from COINBASE_CDP_PRIVATE_KEY. The PEM is imported once at startup and cached — only the JWT is minted per request.

Run

# stdio (default — for Claude Desktop, Cursor, etc.)
npx @codespar/mcp-coinbase-cdp

# HTTP (for server-to-server testing)
MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-coinbase-cdp
