LendMail connector for AI assistants

LendMail decodes credit card and loan offers you get in the mail. The LendMail connector lets an AI assistant that supports the Model Context Protocol (MCP) use that analysis inside your chat. It is free and needs no account or API key.

Connector URL

https://www.lendmail.fit/api/mcp

Transport: Streamable HTTP. Authentication: none.

How it works

Ask your assistant to start a LendMail mail analysis. It calls the connector and gives you a link on lendmail.fit.
Open the link within 30 minutes and upload a photo of the letter on LendMail. Your photo goes to LendMail, not through the assistant.
Go back to the assistant and ask it to get your LendMail analysis. It retrieves the result: who sent the offer, the key terms, fine-print flags, a score, and the response code and website printed on the letter.

Tools: start_mail_analysis, get_mail_analysis, and analyze_mail_piece (an older name kept for compatibility; it also just returns an upload link).

Add it to your assistant

Menus and plan requirements belong to each assistant and can change. LendMail is not affiliated with or endorsed by any of these companies.

Claude

In Claude, go to Customize › Connectors › Add custom connector, name it LendMail, and paste the connector URL. Claude’s Free plan allows one custom connector.

ChatGPT

On ChatGPT Business and Enterprise/Edu (web), a workspace admin or authorized member can add a custom MCP server from Plugins › + › Add custom MCP server with the connector URL and no authentication. On Pro (and possibly Plus), OpenAI currently allows custom MCP servers with read/fetch tools only, so starting a session may not be available there.

Gemini

At gemini.google.com, open Settings › Connected Apps › Custom apps, choose Add a custom app, and enter the connector URL. Google currently limits custom apps to personal Google accounts in the US (18+, English, with Keep Activity on).

Perplexity

On Perplexity Pro or Max, add a custom remote MCP connector, paste the connector URL, and set authentication to None.

Meta Muse

Muse has no settings form for custom connectors. Ask Muse in a chat: “Create a custom connector called LendMail for the MCP server at https://www.lendmail.fit/api/mcp (Streamable HTTP, no authentication).” Muse walks you through the rest.

Grok

Open grok.com/connectors, choose New Connector › Custom, and paste the connector URL. If you added LendMail before, remove it and add it again so Grok loads the current tools.

Cursor

Add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "lendmail": {
      "url": "https://www.lendmail.fit/api/mcp"
    }
  }
}

VS Code

Add this to .vscode/mcp.json in your workspace:

{
  "servers": {
    "lendmail": {
      "type": "http",
      "url": "https://www.lendmail.fit/api/mcp"
    }
  }
}

How to tell the result came from LendMail

The assistant shows a call to a LendMail tool such as start_mail_analysis.
The upload link starts with https://www.lendmail.fit/bot?session=.
The assistant can’t return a LendMail result until you’ve uploaded the photo.

Privacy and limits

Photos are uploaded on LendMail and analyzed there; the connector never receives image data. Session links expire after 30 minutes and can be used once. Requests are rate limited. See the Privacy Policy and Terms of Use.

Affiliate disclosure

Completed results include a link to compare personal loan rates with Upstart. That is an affiliate link: LendMail may earn a commission if you check a rate or apply through it. It does not change the analysis. LendMail is not a lender and does not make loans, and results are general information, not financial advice.
