LenderWiki MCP Server

A Model Context Protocol (MCP) server that gives AI assistants access to LenderWiki's database of 13,000+ US consumer lenders. Search, compare, and analyze personal loan providers with real data on rates, fees, eligibility, customer reviews, and regulatory history.

What It Does

This server exposes four tools that any MCP-compatible AI client (Claude Desktop, Cursor, Windsurf, etc.) can use to query LenderWiki's live database:

Tool	Description
find_lenders	Search lenders by state, type, credit score, ITIN acceptance, cosigner, loan amount, product type, APR, and credit check type
get_lender_profile	Get a comprehensive lender profile — products, rates, eligibility, reviews, regulatory status
compare_lenders	Side-by-side comparison table for 2–5 lenders
check_eligibility	Preliminary eligibility check based on a user's financial profile

Example Prompts

Once connected, you can ask your AI assistant things like:

• "Find lenders in California that accept ITIN"
• "Show me Upstart's full profile — rates, fees, who can apply"
• "Compare SoFi vs LendingClub vs Avant side by side"
• "I have a 620 credit score, $45k income, and I'm in Texas. Check if I'm eligible for Oportun"
• "What lenders accept applicants with no credit history?"
• "Find online lenders with loan amounts between $5,000 and $20,000"
• "Which lenders allow cosigners and don't do a hard credit pull?"

{
  "mcpServers": {
    "lenderwiki": {
      "command": "node",
      "args": ["/path/to/lenderwiki-mcp-server/dist/index.mjs"],
      "env": {
        "LENDERWIKI_API_KEY": "your-api-key-here"

npx (No Installation)

If published to npm, you can use it directly:

{
  "mcpServers": {
    "lenderwiki": {
      "command": "npx",
      "args": ["lenderwiki-mcp-server"],
      "env": {
        "LENDERWIKI_API_KEY": "your-api-key-here"
      }
    }
  }
}

Hosted HTTP Endpoint (Smithery / Remote MCP)

LenderWiki also hosts the MCP server over HTTP so you can connect without running anything locally.

Streamable HTTP (Recommended)

Endpoint: https://lenderwiki.com/api/mcp

This implements the MCP Streamable HTTP transport. Use this for Smithery, remote MCP clients, and any tool that supports HTTP-based MCP.

POST https://lenderwiki.com/api/mcp
Content-Type: application/json
Accept: application/json, text/event-stream

Legacy SSE

For clients that only support the older SSE transport:

• SSE endpoint: GET https://lenderwiki.com/api/sse
• Message endpoint: POST https://lenderwiki.com/api/messages?sessionId=<id>

Smithery Configuration

When submitting to Smithery, use:

• Transport: Streamable HTTP
• URL: https://lenderwiki.com/api/mcp
• Authentication: None required (rate-limited by IP)

• Online lenders & fintechs (Upstart, SoFi, LendingClub, etc.)
• Banks & credit unions
• CDFIs (Community Development Financial Institutions)

• Tribal lenders

Each lender profile may include:

• Eligibility — Credit score minimums, income requirements, employment types, ITIN/SSN, bankruptcy restrictions
• Customer Feedback — Google ratings, BBB ratings, common praises and warnings
• Regulatory — CFPB complaint counts/trends, active warnings, enforcement actions

Data is sourced from lender websites, NerdWallet, Bankrate, CFPB, BBB, and regulatory databases. Each record includes a data_confidence score (0–100%) and last_verified_at timestamp.

git clone https://github.com/lenderwiki/mcp-server.git
cd lenderwiki-mcp-server
npm install
npm run build

Test locally:

LENDERWIKI_API_KEY=your-key node dist/index.mjs

The server communicates over stdio (stdin/stdout) using the MCP protocol. It does not start an HTTP server.
