iflow-mcp_dropbox_mcp-server-dash 0.1.0

An MCP server exposing Dropbox Dash search and file metadata via stdio.

Dropbox Dash MCP Server

An MCP server that exposes Dropbox Dash search and file metadata via STDIO using the Python MCP server library (fastmcp). Authenticate with Dropbox, then search across all company content and fetch detailed file metadata and content.

Tools Implemented

• dash_get_auth_url

  • Summary: Start Dropbox OAuth; returns the authorization URL.
  • Args: none
  • Returns (text): A short instruction message followed by the URL.
  • Notes: Use when not yet authenticated or when a token has expired. After approval in the browser, call dash_authenticate with the one-time code. Tokens are stored securely in your system keyring, so this is typically a one-time setup.

• dash_authenticate

  • Summary: Complete OAuth using the one-time authorization code.
  • Args:
    • auth_code (string, required)
  • Returns (text): Account display name and email on success; a human-readable error on failure.
  • Notes: Persists a token for subsequent tool calls. Typically only needed once until the token expires or is revoked.

• dash_company_search

  • Summary: Search company content indexed by Dropbox Dash.
  • Args:
    • query (string, required) — search text
    • file_type (string or null, optional) — one of: document, image, video, audio, pdf, presentation, spreadsheet; or null for no filter. Default: null. The value document is also treated as no filter.
    • connector (string or null, optional) — filter by connector source. Common connectors include confluence, dropbox, github, gmail, gong, google_calendar, google_drive, jira, microsoft_365, microsoft_teams, slack, workday, zoom, among others. Default: null for no connector filter.
    • start_time (string or null, optional) — filter results modified after this datetime (ISO 8601 format, e.g., 2025-10-30T16:24:12.071Z). Default: null for no start time filter.
    • end_time (string or null, optional) — filter results modified before this datetime (ISO 8601 format, e.g., 2025-10-31T16:24:12.071Z). Default: null for no end time filter.
    • max_results (integer, optional) — default 20, range 1..100
  • Returns (text): A formatted list of results. Each result includes labeled fields such as UUID:, Type:, URL:, Preview:, Description:, File Type:, MIME Type:, Source:, Creator:, Last Modified By:, Updated:, Source Updated:, Relevance:, Source ID:. Results are separated by a divider line.
  • Errors: Human-readable messages for invalid parameters or missing authentication.

• dash_get_file_details

  • Summary: Fetch detailed metadata (and optional content snippet) for a result UUID.
  • Args:
    • uuid (string, required) — UUID from search results
  • Returns (text): A summary with labeled fields (Title, Link, Updated, Source Updated, MIME Type, Source, Creator, Last Modified By). Media sections are included when present (Video/Image metadata). Content, when available, is shown with a MIME type and may be truncated to ~20,000 characters.
  • Errors: Human-readable messages for missing authentication or unknown UUID.

First-Time (or Re-Auth) Flow

If the user is not yet authenticated (or the token has expired):

1. dash_get_auth_url → open the URL and approve access.
2. dash_authenticate(auth_code) → store the token.
3. Proceed with dash_company_search(...) and dash_get_file_details(uuid).

Prerequisites

Before installing and running the MCP server, you need to create a Dropbox app to obtain API credentials:

1. Go to dropbox.com/developers/apps
2. Click on Create app
3. Select Scoped access as the API type
4. Choose Full Dropbox access
5. Give your app a name
6. After creating the app, go to the Permissions tab and enable:
   • files.metadata.read
   • files.content.read
7. Take note of the App key value from the Settings tab (you'll need this for configuration)

This credential will be used as APP_KEY in the installation steps below.

Requirements

• Python 3.10 or higher
• Dropbox Dash API credentials (App key)
• Network access to Dropbox APIs

Installation

Clone the repository:

git clone https://github.com/dropbox/mcp-server-dash
cd mcp-server-dash

Install uv for virtual environment and dependency management:

macOS (Homebrew)

brew install uv

macOS/Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows (PowerShell):

irm https://astral.sh/uv/install.ps1 | iex

Set up the virtual environment and install dependencies

uv sync

Provide credentials (environment or .env)

export APP_KEY=your_dropbox_app_key
# or create a .env file with APP_KEY
# e.g., copy the example file:
cp .env.example .env

Usage

Running the MCP Server in STDIO mode

uv run src/mcp_server_dash.py

Authenticate via tools: call dash_get_auth_url, then dash_authenticate with the code. The access token is securely stored in your system's keyring (macOS Keychain, Windows Credential Manager, or Linux Secret Service).

Token Management

Tokens are stored securely in your system keyring under the service name mcp-server-dash or in ~/.mcp-server-dash/dropbox_token.json

To clear a stored token, use:

uv run src/mcp_server_dash.py --clear-token

Common MCP Server Configuration

For most MCP clients, including Claude and Cursor, you need to insert the below JSON configuration into a specific configuration file. See the specific instructions for Claude and Cursor below.

❗ Important: Update the configuration below with the path to your installation and with your APP_KEY.

MCP Server Configuration:

{
  "mcpServers": {
    "Dropbox Dash Search": {
      "command": "uv",
      "args": [
          "--directory",
          "/path/to/mcp-server-dash/",
          "run",
          "src/mcp_server_dash.py"
      ],
      "env": {
        "APP_KEY": "your_dropbox_app_key"
      }
    }
  }
}

Security Note: For better security, consider using environment variables or a .env file with restrictive permissions (excluded from version control) instead of placing credentials directly in the MCP config file.

Using Claude as the Client

• Open Claude Desktop → Settings → Developer → Local MCP Servers → Edit Config
• Add the JSON MCP Server configuration shown above.
• Restart Claude Desktop after saving the config.

Using Cursor as the Client

• Press Cmd+Shift+P (macOS) or Ctrl+Shift+P (Windows) to open the Command Palette
• Type "View: Open MCP Settings"
• Add the JSON MCP Server Configuration to the mcp.json file as instructed.

Using Goose as the Client

• Select Extensions → Add custom extension
• Fill out the form:
  • Extension Name: Dropbox Dash Search
  • Type: STDIO
  • Description: Provide company context to your workflows
  • Command: uv --directory /path/to/mcp-server-dash/ run src/mcp_server_dash.py
  • Environment:
    • APP_KEY: Your Dropbox Client ID
• Click Add Extension

Development

Install dev tools (ruff, black, mypy, pytest, coverage) using uv:

uv pip install -e ".[dev]"

Lint, Format, Type-check

Run checks (via uv):

# Lint (imports, style, bugbear, etc.)
uv run ruff check .

# Format (apply changes)
uv run black .

# Type-check
uv run mypy src

Tip: use uv run ruff format . (or uv run black .) to auto-format, and uv run ruff check --fix . to apply safe autofixes.

Testing & Coverage

Run the test suite (quiet mode with coverage summary) using uv:

uv run pytest
# or explicitly with coverage flags
uv run pytest -q --cov=src --cov-report=term-missing

Debugging

You can inspect and debug the server with the Model Context Protocol Inspector:

npx @modelcontextprotocol/inspector uv run src/mcp_server_dash.py

Ensure APP_KEY is set in your environment or .env before running the inspector.
