BlindPay MCP Server

The official Model Context Protocol server for BlindPay - Stablecoin API for global payments.

What This MCP Server Does

This MCP server provides AI assistants (Cursor, Claude Code, Codex, etc.) with access to BlindPay's stablecoin payment infrastructure. It exposes tools that allow AI assistants to:

Create and manage receivers (individuals/businesses)
Process payouts and payins on multiple blockchains
Create quotes and get FX rates
Manage virtual accounts and blockchain wallets
Configure webhooks and API keys
And more...

Two ways to connect

	Remote server (recommended)	Local `npx` server
URL / command	`https://mcp.blindpay.com/mcp`	`npx -y @blindpay/mcp`
Auth	OAuth 2.1 sign-in with your BlindPay account (PKCE)	`BLINDPAY_API_KEY` env var
Transport	Streamable HTTP	stdio
Works in	Claude, ChatGPT, Cursor, VS Code, Grok, any remote-capable client	Any stdio MCP client

Both expose the same tools. The remote server needs no API key: the client opens a browser, you sign in and pick an instance, and the token is scoped to your role on it.

Tool profiles

Set BLINDPAY_MCP_PROFILE on the local server to choose which tools are exposed:

Profile	Tools	Use when
`full` (default)	Every public API operation, including payouts and transfers	Building or operating with an AI coding assistant
`readonly`	`GET` operations only: status, balances, quotes, history	Consumer assistants, or any place a tool that moves money is unwanted

Every tool carries MCP annotations (readOnlyHint, destructiveHint, idempotentHint) derived from its HTTP verb, so clients can gate confirmations themselves.

Prerequisites (local server only)

Get your API key and Instance ID:

Create an account on BlindPay
Create a development instance
Go to the BlindPay Dashboard
Select your instance and click on the API Keys tab
Create a new API key
Copy your instance ID (format: in_xxxxxxxxxxxx) from the dashboard url

Dependencies you need to have installed:

Node.js
Npm

You can check if you have Node.js installed by running node -v. Same for Npm, you can check by running npm -v.

Installation

Cursor

One-click install (remote server):

One-click install (local server with API key):

Add MCP to Cursor

After installation, add your API key and instance ID to ~/.cursor/mcp.json:

config.json

{
  "mcpServers": {
    "blindpay": {
      "command": "npx",
      "args": ["-y", "@blindpay/mcp"],
      "env": {
        "BLINDPAY_API_KEY": "your-api-key-here",
        "BLINDPAY_INSTANCE_ID": "your-instance-id-here"
      }
    }
  }
}

Claude Code

As a plugin (remote server, OAuth, no API key):

Terminal

claude plugin marketplace add blindpaylabs/blindpay-mcp
claude plugin install blindpay@blindpay

Or as a plain MCP server:

Terminal

claude mcp add --transport http blindpay https://mcp.blindpay.com/mcp

Local server with an API key:

Terminal

claude mcp add --transport stdio blindpay --env BLINDPAY_API_KEY=your-api-key-here --env BLINDPAY_INSTANCE_ID=your-instance-id-here -- npx -y @blindpay/mcp

Claude Desktop

Add to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

config.json

{
  "mcpServers": {
    "blindpay": {
      "command": "npx",
      "args": ["-y", "@blindpay/mcp"],
      "env": {
        "BLINDPAY_API_KEY": "your-api-key-here",
        "BLINDPAY_INSTANCE_ID": "your-instance-id-here"
      }
    }
  }
}

Codex

Remote server (OAuth, no API key):

bash

codex mcp add blindpay --url https://mcp.blindpay.com/mcp

Local server with an API key:

bash

codex mcp add blindpay --env BLINDPAY_API_KEY=your-api-key-here --env BLINDPAY_INSTANCE_ID=your-instance-id-here -- npx -y @blindpay/mcp

Or add to your ~/.codex/config.toml (or project-scoped .codex/config.toml):

toml

[mcp_servers.blindpay]
command = "npx"
args = ["-y", "@blindpay/mcp"]

[mcp_servers.blindpay.env]
BLINDPAY_API_KEY = "your-api-key-here"
BLINDPAY_INSTANCE_ID = "your-instance-id-here"

VS Code

Click the Install in VS Code badge at the top, or add to .vscode/mcp.json:

config.json

{
  "servers": {
    "blindpay": {
      "type": "http",
      "url": "https://mcp.blindpay.com/mcp"
    }
  }
}

You can also search @mcp blindpay in the Extensions view once the gallery entry is live.

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

config.json

{
  "mcpServers": {
    "blindpay": {
      "serverUrl": "https://mcp.blindpay.com/mcp"
    }
  }
}

Raycast

Open the Model Context Protocol Registry extension in Raycast, search for BlindPay and click Install Server. Or install manually with Manage Servers → Add Server using the local config from the Cursor section.

Claude (claude.ai / Claude Desktop, remote)

In Settings → Connectors → Add custom connector, paste https://mcp.blindpay.com/mcp and complete the sign-in. Only read-only tools are exposed to consumer directories.

ChatGPT

Enable Developer Mode in Settings → Connectors → Advanced, then Create a connector with https://mcp.blindpay.com/mcp and OAuth authentication.

Grok

Grok Build plugin (recommended): install blindpay from the xAI plugin marketplace. The plugin ships both remote HTTP MCP endpoints:

Server	URL	Scope
`blindpay`	`https://mcp.blindpay.com/mcp`	Full (read + write)
`blindpay-readonly`	`https://mcp.blindpay.com/mcp/readonly`	Read-only

Both use OAuth 2.1 (PKCE) with your BlindPay account — no API key to paste.

Custom connector (paid Grok tier): go to https://grok.com/connectors → New Connector → Custom, enter https://mcp.blindpay.com/mcp (or the readonly URL), leave client credentials empty, and complete the BlindPay sign-in when prompted.

Gemini CLI

bash

gemini extensions install https://github.com/blindpaylabs/blindpay-mcp

Docker

Local stdio server in a container (also listed in the Docker MCP Registry):

Terminal

docker run -i --rm -e BLINDPAY_API_KEY=your-api-key-here -e BLINDPAY_INSTANCE_ID=your-instance-id-here ghcr.io/blindpaylabs/blindpay-mcp

Build it yourself with docker build -t blindpay-mcp . from this repo.

Any other MCP client

Remote: point the client at https://mcp.blindpay.com/mcp (Streamable HTTP, OAuth 2.1 discovery via /.well-known/oauth-protected-resource). Local: run npx -y @blindpay/mcp over stdio with BLINDPAY_API_KEY set.

Example Prompts

Once configured, you can ask your AI assistant to interact with BlindPay:

Code

"Get me a quote for sending 1000 USDC to a bank account in Brazil"

"List all my recent payouts from the last 7 days"

"Create a virtual account for receiver with ID re_xxxxxxxxxxxx"

"Show me the available payment rails"

"Get all receivers for instance in_xxxxxxxxxxxx"

[!TIP] You can specify BLINDPAY_INSTANCE_ID in your initial prompt or add it as an environment variable. However, some AI tools may not detect it automatically, so you may need to include it explicitly in your prompt.
