# MCP Overview
> Connect Claude and ChatGPT to SecureLend's marketplace and underwriting agents
# Model Context Protocol (MCP)
SecureLend provides two production MCP endpoints:
| Endpoint | Purpose |
| ---------------------------------- | ------------------------------------------------------------------------------------------ |
| `https://mcp.securelend.ai/mcp` | Loan comparison marketplace — 22 tools for borrowers and lenders |
| `https://agents.securelend.ai/mcp` | Agentic underwriting tools — pitch deck precheck, IC memo, document intelligence, and more |
The marketplace is also **live in the ChatGPT App Store** — no manual setup required for borrower-facing workflows.
## What is Model Context Protocol?
Model Context Protocol (MCP) is an open standard that allows AI assistants to connect to external tools and data sources. Our MCP server enables Claude and ChatGPT to:
* Compare personal and business loans in real-time
* Calculate mortgage and loan payments
* Compare credit cards and banking products
* Submit loan applications on behalf of users
* Track application status
## Who is it for?
**Borrowers:**
* Compare 200+ lenders for personal, business, and equipment loans inside ChatGPT or Claude
* Get instant loan comparisons through natural conversation — no need to visit multiple lender websites
* Easiest path: open the [SecureLend ChatGPT app](https://chatgpt.com/apps/securelend/asdk_app_69513da1b04881919f74ae07c00a11f2#) directly
**VC firms and lenders:**
* Precheck pitch decks against your rubric (\$0.50/check, first 15/month free)
* Generate IC memos, credit memos, and underwriting memos from a deal workspace
* Connect via `agents.securelend.ai/mcp` — see [underwriting agents setup](/mcp/setup#underwriting-agents---manual-mcp-setup)
**Developers:**
* Build AI-powered financial applications using our TypeScript SDK
* Integrate loan comparison or underwriting workflows programmatically
* See [SDK documentation](/sdk/javascript)

## Example Use Cases
### Personal Finance
> "Compare personal loans for \$25,000 to consolidate credit card debt. My credit score is 720."
The AI assistant will use `compare_personal_loans` to fetch and compare offers from multiple lenders, presenting the best options with rates, terms, and monthly payments.
### Business Financing
> "I need a $200,000 equipment loan for my restaurant. My business has $1.2M annual revenue and I've been operating for 3 years."
The AI will use `compare_business_loans` with your business profile to find competitive offers, then can help you submit applications with `get_offer`.
### Home Buying
> "What would my monthly payment be on a \$400,000 home with 20% down at 6.5% interest, including taxes and insurance?"
The AI uses `calculate_mortgage_payment` to provide a complete PITI breakdown.
