What is the ConvertFileFast MCP server?

It is a Model Context Protocol server that exposes ConvertFileFast conversion features as tools for AI agents. Agents can call document conversions, PDF tools and image tools through a standard MCP client.

Should I use the remote MCP server or the local package?

Use the remote MCP server when your client supports Streamable HTTP. Use the local npm or PyPI package when the client only supports stdio or when you want local file paths instead of temporary hosted download URLs.

How is authentication handled?

Every request uses the user's own ConvertFileFast API key through X-API-Key or Authorization Bearer headers. The hosted MCP server forwards the key to the API and does not persist it.

Remote and local MCP server

Advantages

Why use the ConvertFileFast MCP server?

A secure tool surface for AI agents that need document conversion, PDF processing and image optimization workflows.

Hosted remote MCP

Connect directly to https://mcp.convertfilefast.com/mcp when your client supports Streamable HTTP. No local process required.

Local stdio install

Use npm or PyPI for desktop clients that prefer a local MCP process. Local and remote expose the same tool surface.

Per-user API keys

The MCP server does not store shared credentials. Each user sends their own ConvertFileFast API key with every request.

Conversion-focused tools

Agents can convert documents, create PDFs from images, merge, split, compress, rotate, protect and unlock PDFs, extract text, and resize or compress images.

Temporary downloads

Remote file-producing tools return short-lived download URLs, avoiding long binary payloads in agent conversations.

Same API limits

MCP calls use the same ConvertFileFast API key, permissions, rate limits and monthly usage limits as direct API requests.

Every tool an agent gets

Adding the server exposes these 18 tools. File tools consume conversion credits; account tools do not.
