bridgerton

CLI and MCP server for Bridge.xyz stablecoin infrastructure.

Install

npm install -g bridgerton

Or run directly:

npx bridgerton --help

Setup

On first run with no arguments, bridgerton prompts for your API key interactively. Or configure it explicitly:

bridgerton configure api-key sk-test-...

You can also set it via environment variable:

export BRIDGE_API_KEY=sk-test-...

Environment is auto-detected from the key prefix — sk-test-* routes to sandbox, sk-live-* to production.

Stripe Issuing commands use a Stripe secret key from STRIPE_SECRET_KEY, then STRIPE_API_KEY, then the saved config:

bridgerton configure stripe-api-key sk_live_...

Tempo Wallet-Backed Cards

For Bridge-managed consumer cardholders, Bridge owns onboarding, ToS, KYC, endorsements, and the link to the Stripe Issuing cardholder. Stripe owns new Tempo wallet-backed card issuance after Bridge returns a stripe_cardholder_id.

Start with Bridge and wait for the customer to complete hosted ToS and KYC:

bridgerton customers create -f John -l Doe -e john@example.com

bridgerton customers tos-acceptance-link <customer-id>
bridgerton customers kyc-link <customer-id> --endorsement cards

bridgerton customers get <customer-id>

Send the hosted ToS and KYC links to the customer, then poll customers get until ToS/KYC are approved, the cards endorsement is approved, and the customer includes a stripe_cardholder_id.

Then create the Tempo wallet-backed Stripe card:

bridgerton cards create \
  --cardholder <stripe-cardholder-id> \
  --wallet-address <tempo-wallet-address> \
  --idempotency-key tempo-cards-<bridge-customer-id> \
  --bridge-customer-id <bridge-customer-id>

Bridge's deprecated Cards API operation is card account provisioning (POST /customers/{customerID}/card_accounts). New stablecoin card issuance and management for Tempo wallet-backed cards lives under bridgerton cards. Existing Bridge card-account utility endpoints such as list, get, update, freeze, unfreeze, transactions, authorizations, withdrawals, PIN update URL, ephemeral keys, card-account statements, card designs, and program summary remain available under bridgerton bridge-cards.

For non-custodial Tempo wallets, approve Bridge's issuer contract before testing live spend:

tempo wallet whoami --json-output

export TEMPO_ROOT_ACCOUNT=0x...
export USDC_E=0x20c000000000000000000000b9537d11c60e8b50
export ISSUER=0x3e8f24b686aa8c036038f7d557b70e6ce0e7b56b

cast erc20-token approve "$USDC_E" "$ISSUER" <allowance-base-units> \
  --rpc-url https://rpc.tempo.xyz \
  --chain 4217 \
  --from "$TEMPO_ROOT_ACCOUNT" \
  --browser

cast call "$USDC_E" "allowance(address,address)(uint256)" "$TEMPO_ROOT_ACCOUNT" "$ISSUER" \
  --rpc-url https://rpc.tempo.xyz

Use the Tempo wallet signer for approval. Do not store Tempo access keys in Bridgerton config.

Card statements include sensitive financial data and must be written to a file:

bridgerton cards statements create \
  --cardholder <stripe-cardholder-id> \
  --card <stripe-card-id> \
  --period 202605 \
  --output statement-202605.pdf

Card issuance smoke test checklist:

1. Retrieve the cardholder with bridgerton cards cardholders get <stripe-cardholder-id>.
2. Create the card with a stable --idempotency-key, then rerun the same command and confirm the same card is returned.
3. Retrieve the card with bridgerton cards get <card-id> and confirm type=virtual, status=active, currency=usd, and the Tempo wallet metadata.
4. Run a small live authorization, then check Stripe Issuing activity and the wallet allowance/balance on Tempo.

Agent Setup

Give your AI agent (Claude Code, Amp, Cursor, Copilot, etc.) full access to Bridge.xyz:

npx bridgerton mcp add      # register as MCP server — gives agents direct tool access
npx bridgerton skills add   # install skill files — gives agents context on available commands

That's it. Your agent can now run commands like "create a wallet on tempo for a customer" or "list all transfers".

You can also run the MCP server directly in stdio mode:

bridgerton --mcp

Development

bun install
bun run build        # tsc + chmod
bun run typecheck    # tsc --noEmit
