Files.com MCP Server

The files-com-mcp Python package lets your AI application interact with Files.com. It is for local use only and supports STDIO only: your MCP client starts the package as a subprocess on the same machine.

For MCP connections over a network, use the Files.com hosted MCP service.

Set FILES_COM_API_KEY in the environment your client passes to the subprocess. The local package makes outbound requests to the Files.com API to perform site operations.

Files.com is the cloud-native, next-gen MFT, SFTP, and secure file-sharing platform that replaces brittle legacy servers with one always-on, secure fabric. Automate mission-critical file flows—across any cloud, protocol, or partner—while supporting human collaboration and eliminating manual work.

With universal SFTP, AS2, HTTPS, and 50+ native connectors backed by military-grade encryption, Files.com unifies governance, visibility, and compliance in a single pane of glass.

Introduction

The Files.com Python MCP package lets Claude Desktop and other local MCP clients upload and download files, query folders, manage users, and run automations on your Files.com site. It uses the permissions of your API key, and its actions are logged like those of any other API client.

The Python package supports local use over STDIO (standard input and output) only. Your MCP client starts it on the same machine and communicates directly with that process, without a network listener. The package still needs outbound access to the Files.com API.

What MCP Is

The Model Context Protocol (MCP) is a standard interface through which a Large Language Model calls real APIs as part of its work. An MCP server hands the model a set of tools, and each Files.com tool is an authenticated operation in your site. With the server connected, the model can:

• Transfer files between cloud and on-premises systems
• Query folders and file metadata
• Create and manage users
• Automate workflows such as archiving or sharing

Common Use Cases

Assistants for operations teams. An internal chatbot fetches or archives files on request.

Automated workflows. An agent reacts to an incoming support request, then retrieves or uploads the files the case needs.

Developer copilots. A development-focused LLM creates users, provisions folders, or reads files while debugging.

Local vs. Hosted MCP

Use the local Python package with clients that launch STDIO servers, including Claude Desktop.

For clients that connect to MCP over a network, use the Files.com hosted MCP service. Files.com operates the server, so you do not need to install the Python package. Running the Python package as an HTTP or SSE service is unsupported, including during development.

Install uv, register uvx files-com-mcp as an MCP server in your LLM client, and give it a Files.com API key in the FILES_COM_API_KEY environment variable.

Installation

The files-com-mcp Python package lets your MCP client call the Files.com API through a process running on your machine. It supports local use over STDIO (standard input and output) only. For clients that connect to MCP over a network, use the Files.com hosted MCP service.

Requirements

Your MCP client must be able to start a local STDIO server. Your machine needs outbound access to the Files.com API.

The examples run the server with uvx, which is part of uv. It runs a Python tool in an isolated environment of its own, so there is nothing to install or configure by hand beyond uv itself. Install uv first.

Registering The Server

Set your client's local STDIO server command to uvx with files-com-mcp as the argument. uvx downloads the package on first use and starts it each time your client launches the server.

The Claude Desktop configuration shows these settings in JSON. For other clients, follow their instructions for adding a local STDIO server.

Authentication

The server authenticates to Files.com with an API key, read from the FILES_COM_API_KEY environment variable that your client passes to it. The model can do exactly what the key's user can do, so create a key for this purpose with the permissions the agent needs and no more.

Restricting Local File Transfers

Optionally set FILES_COM_LOCAL_ROOT in your client's server environment to an existing absolute directory path, such as /home/user/Documents. Uploads can only read files within that directory and its children, and downloads can only write there. When the variable is omitted or empty, transfers can use any local path accessible to the server.

The server resolves .. and symbolic links before checking each path. Relative transfer paths are resolved from the server's working directory and must still stay inside the configured directory. A download can create a new file in an existing directory within the boundary. A nonempty value must name an existing absolute directory; otherwise, the server will not start.

This setting applies to local transfer paths. Files.com paths continue to follow the API key's permissions.

uvx files-com-mcp

FILES_COM_API_KEY=your-api-key uvx files-com-mcp

FILES_COM_API_KEY=your-api-key FILES_COM_LOCAL_ROOT=/home/user/Documents uvx files-com-mcp

Using With Claude

Claude Desktop uses the Files.com Python MCP package to call the Files.com API from your machine. This setup supports local use over STDIO (standard input and output) only. For a network connection to MCP, use the Files.com hosted MCP service.

Claude Desktop reads its MCP servers from claude_desktop_config.json. Add the entry on the right under mcpServers, replace the FILES_COM_API_KEY value with a Files.com API key, and restart Claude Desktop. The MCP quickstart shows where the file lives on each operating system, walking through the same steps for another server.

The entry starts the server with uvx, so uv has to be installed first; see Installation.

Once Claude has restarted, the Files.com tools appear in its tool list. Tools lists them by category and explains why it pays to enable only the ones a task needs.

To restrict local uploads and downloads, optionally add "FILES_COM_LOCAL_ROOT": "/home/user/Documents" alongside FILES_COM_API_KEY in the env object, using an existing absolute directory on your machine. Restart Claude Desktop after changing it. See Restricting Local File Transfers for details.

Tools

The Files.com MCP server exposes the tools below, grouped by category: files, folders, sharing, users, logs, automations and the other Files.com resources. Each tool is one operation in your site, run with the permissions of the API key the server holds.

Keep The Toolset Focused

A model picks the right tool more reliably from a short list. If the LLM uses Files.com tools inconsistently, it is most likely choosing among too many. Most clients let you enable and disable an MCP server's tools one by one; enable only the ones the agent's task needs.
