MCP for Fintech AI Agents

Why financial API integration is hard for AI

Transaction triage agents and financial chatbots need live access to ledgers, bank statements, and payment gateways. Exposing these via custom scripts expands PCI scope and risks hardcoding static API keys in vulnerable prompt loops. Developers need an out-of-band proxy that securely manages tools and handles routing without passing plain-text keys directly to the model.

How to expose Stripe APIs to MCP

# Example: Connecting a fintech AI agent to Stripe via wmcp.sh
import anthropic
import httpx

client = anthropic.Anthropic(api_key="your-api-key")
# Retrieve dynamically generated MCP tools from Stripe OpenAPI
response = httpx.get(
    "https://wmcp.sh/api/v1/tools?url=https://raw.githubusercontent.com/stripe/openapi/master/openapi/spec3.yaml",
    headers={"Authorization": "Bearer YOUR_ENCRYPTED_CREDENTIALS"}
)
stripe_tools = response.json()

completion = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    tools=stripe_tools,
    messages=[{"role": "user", "content": "Check the latest invoice status for Acme Corp."}]
)
print(completion.content)
