@codespar/mcp-flow-cl
MCP server for Flow (flow.cl) — the Chile-native PSP: one hosted payment order covers Webpay (credit/debit), ETpay bank transfer, cash networks and international cards. Refunds included. Every API call is HMAC-SHA256 signed.
Quick Start
Claude Desktop
Add to ~/.config/claude/claude_desktop_config.json:
{
"mcpServers": { "flow-cl": { "command": "npx", "args": ["-y", "@codespar/mcp-flow-cl"], "env": { "FLOW_API_KEY": "your-flow-api-key", "FLOW_SECRET_KEY": "your-flow-secret-key", "FLOW_ENV": "sandbox" } } } }
Claude Code
claude mcp add flow-cl --env FLOW_API_KEY=... --env FLOW_SECRET_KEY=... -- npx -y @codespar/mcp-flow-cl
Cursor / VS Code
Add the same block to .cursor/mcp.json or .vscode/mcp.json.
Tools (8)
| Tool | Endpoint | What it does |
|---|---|---|
create_payment | POST /payment/create | Hosted payment order; returns url + token the customer pays at |
create_payment_by_email | POST /payment/createEmail | Flow emails the customer a collection link |
get_payment_status | GET /payment/getStatus | Status by Flow token (1 pending, 2 paid, 3 rejected, 4 canceled) |
get_payment_status_by_commerce_id | GET /payment/getStatusByCommerceId | Status by your commerceOrder |
get_payment_status_by_flow_order | GET /payment/getStatusByFlowOrder | Status by Flow order number |
list_payments | GET /payment/getPayments | Payments received on a date (paged) |
create_refund | POST /refund/create | Full or partial refund order |
get_refund_status | GET /refund/getStatus | Refund status by refund token |
Authentication
Flow signs every request: parameters are sorted alphabetically, concatenated as name+value, and signed with HMAC-SHA256 using your secretKey. This server does the signing for you — set the two env vars and call tools with plain arguments.
| Variable | Required | Description |
|---|---|---|
FLOW_API_KEY | yes | Flow merchant API key |
FLOW_SECRET_KEY | yes | HMAC signing secret (never sent on the wire) |
FLOW_ENV | no | sandbox (default) or production |
Sandbox: register at sandbox.flow.cl — the sandbox issues its own key pair.
Example
"Create a Flow payment order for CLP 25,000, subject 'Plan Pro mensual', email cliente@ejemplo.cl, and give me the payment link."
The agent calls create_payment and returns url?token=... — the customer picks Webpay, ETpay or cash at Flow's hosted page.
Enterprise
Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.
Managed tier
This open-source server calls Flow's API directly with your credentials. CodeSpar's managed tier routes one interface across every LATAM provider with automatic failover, governance, audit and a credential vault: codespar.dev/agents.
