MCP server for Coinbase Advanced Trade — global crypto exchange.
Mirrors the foxbit pattern (HMAC-signed REST per request).
13 tools: list_accounts / get_account / list_products / get_product
/ get_best_bid_ask / get_market_trades / create_order / list_orders
/ get_order / cancel_orders / list_fills / get_transaction_summary
/ list_portfolios.
Signing: HMAC-SHA256 with unix-seconds timestamp (different from
Foxbit which uses ms). Prehash: ${ts}${UPPER_METHOD}${path_with_query}${body}
with no separators. Hex signature. Headers CB-ACCESS-KEY /
CB-ACCESS-TIMESTAMP / CB-ACCESS-SIGN.
Env vars: COINBASE_ACCESS_KEY + COINBASE_API_SECRET (legacy HMAC keys
minted from coinbase.com/settings/api). New JWT-ECDSA Coinbase Cloud
keys are NOT supported — needs a 7th auth_type on backend (pending).
Files:
- package.json (31 lines)
- tsconfig.json (14)
- server.json (46) — MCP canonical schema (matches foxbit's local copy)
- README.md (136) — install / config / tools table / CDP caveat
- src/index.ts (331) — HMAC helper + 13 tool dispatchers + stdio + http transport
@codespar/mcp-coinbase@0.1.0 published to npm. Distinct from
@codespar/mcp-coinbase-commerce (merchant gateway) and pending CDP
package (onchain wallets / trading / payments).

Input schemas match `codespar-enterprise/packages/api/src/catalog/coinbase.json` verbatim.
Signing
HMAC-SHA256 with unix-seconds timestamp (different from Foxbit's ms). Prehash `${ts}${UPPER_METHOD}${path_with_query}${body}` with no separators. Hex signature. Headers `CB-ACCESS-KEY` / `CB-ACCESS-TIMESTAMP` / `CB-ACCESS-SIGN`.
Auth scope
Env: `COINBASE_ACCESS_KEY` + `COINBASE_API_SECRET` — legacy HMAC keys minted from `coinbase.com/settings/api`. New JWT-ECDSA "Coinbase Cloud" keys are NOT supported — would require a 7th `auth_type` on the managed-tier backend (pending).

Verification
`npm run build` clean. `node dist/index.js` waits on stdio without crashing. Published successfully.
