Connect AI agents and LLMs to real-time UK bank validation using Model Context Protocol
Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI assistants like Claude to securely connect to external data sources and tools. Instead of copying and pasting data or relying on outdated training data, AI agents can directly query real-time information from your systems.
AI agents access live bank validation data, not outdated training information.
API key-based bearer authentication keeps your data protected.
Works with any MCP-compatible AI assistant or custom application.
No servers to manage - just add your API key and connect.
Access both modulus checking and Confirmation of Payee services.
Lightning-fast validation doesn't slow down AI conversations.
Authentication: Bearer token with your API key
Get started with MCP integration in 3 simple steps:
Sign up for a free account at esortcode.com/signup and retrieve your API key from the portal.
Add the eSortcode MCP server to your AI assistant's configuration with your API key as the bearer token.
Ask your AI assistant to validate UK bank accounts - it will automatically query the MCP server in real-time.
See how to integrate eSortcode MCP with popular AI platforms:
Add eSortcode to your Claude Desktop app configuration:
{
"mcpServers": {
"esortcode": {
"command": "npx",
"args": [
"-y",
"mcp-remote@latest",
"https://mcp.esortcode.com/",
"--header",
"Authorization: Bearer YOUR_API_KEY_HERE"
]
}
}
}
Location:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.jsonAfter saving, restart Claude Desktop. You can now ask Claude to validate UK bank accounts!
Create a custom action in ChatGPT to connect to eSortcode MCP:

Steps:
Configure eSortcode MCP server in your Node.js AI agent configuration:
{
"servers": {
"eSortCode": {
"command": "npx",
"args": [
"-y",
"mcp-remote@latest",
"https://mcp.esortcode.com/",
"--header",
"Authorization: Bearer YOUR_API_KEY_HERE"
]
}
}
}
Installation:
YOUR_API_KEY_HERE with your actual API keymcp-remote package will be automatically installed via npxUsage: Once configured, your AI agent can call the MCP server to validate UK bank accounts using the standard MCP protocol.
Configure eSortcode MCP server in your Python AI agent using subprocess:
import subprocess
import json
# MCP Server Configuration
MCP_CONFIG = {
"command": "npx",
"args": [
"-y",
"mcp-remote@latest",
"https://mcp.esortcode.com/",
"--header",
"Authorization: Bearer YOUR_API_KEY_HERE"
]
}
# Start MCP server process
def start_mcp_server():
"""Start the eSortcode MCP server"""
process = subprocess.Popen(
[MCP_CONFIG["command"]] + MCP_CONFIG["args"],
stdin=subprocess.PIPE,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
text=True
)
return process
# Example usage with MCP client library
if __name__ == "__main__":
server = start_mcp_server()
# Connect your MCP client to this server
# Use the standard MCP protocol to communicate
Requirements:
mcp package)YOUR_API_KEY_HERE with your actual API keyNote: The MCP server runs as a subprocess and communicates via standard MCP protocol.
