Perplexity

Run credit checks inside Claude Desktop

The `submit_loan_application` tool sends your raw application data directly to the underwriting system right from your Claude Desktop chat window. You don't need to leave your workspace to trigger credit decisions, as the desktop agent executes the endpoint and prints the real-time approval or denial status on your screen. By coupling this with `get_lendapi_picklists`, your local agent inspects valid metadata fields before formatting the submission payload. This prevents schema validation failures on the server side because Claude Desktop pre-checks the exact fields required by your specific underwriting flow.

Instantly register new borrowers

The `create_new_borrower` tool builds clean borrower profiles using natural language descriptions you type into Claude Desktop. Your local agent maps your raw text directly to the required JSON schema, eliminating the need to write manual curl requests or fill out web forms. Once the profile is built, you can run `get_borrower_details` to verify that the credit history, income, and identity fields are correctly formatted inside the LendAPI database. It means you can audit customer profiles using simple conversational prompts in your local desktop app.

Track loan pipelines from your desktop chat

The `list_loan_applications` tool pulls your active loan pipeline directly into Claude Desktop for fast status reviews. Instead of logging into an external dashboard, you ask the agent to scan the queue, which calls the endpoint to fetch the latest application records. If a specific deal catches your eye, the agent triggers `get_application_details` to pull down the exact underwriting status, debt-to-income ratios, and loan terms. This local MCP Server connection keeps your compliance reviews fast and self-contained.
