await mcp.useTool("dbx-mcp-server", "upload_file", {
  path: "/test.txt",
  content: Buffer.from("Hello World").toString("base64"),

Testing

Run the test suite:

npm test

Tests verify all operations including authentication, file operations, and error handling.

Test Structure

The test suite is organized into several modules:

Dropbox Operations: Tests for basic file operations (upload, download, list, etc.)

Account Operations: Tests for accessing account information

          - **Search and Delete**: Tests for search functionality and safe deletion with recycle bin support

Resource System: Tests for the MCP resource system integration

Handling Test Data

The tests use dynamically generated file and folder names based on timestamps to avoid conflicts. Test data is automatically cleaned up after test execution.

Running Specific Tests

To run a specific test file or test group:

npm test -- tests/dropbox/search-delete.test.ts  # Run specific test file
npm test -- -t "should search for files"        # Run tests matching description

Troubleshooting Tests

If tests fail with timing or authentication issues:

Check that the mock implementations in tests/setup.ts match your test expectations
Ensure test helpers are correctly configured
For Jest scope errors, avoid referencing imported variables in mock factory functions

Development

Built with:

TypeScript
Model Context Protocol SDK
Dropbox SDK v10.34.0
