Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to convertica.net. It runs from a package rather than a hosted endpoint, so there is no endpoint to match against that domain.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that lets an assistant run Convertica's 35+ document and image conversions, such as PDF to Word, PDF merging and HEIC to JPG.

What you can do: List available converters with their file fields and options, to find the right converter slug first. Run a chosen converter on local files, with tool-specific options and an optional output directory. Convert between PDF, Word, Excel, PowerPoint, JPG, HTML, Markdown, Text and EPUB, and to PDF/A. Merge, split, compress, rotate, crop, watermark, sign, protect or unlock PDFs. Convert, optimize and turn HEIC images into JPG, PNG or PDF, and render a URL as a PDF.
When to use it: Useful when you want document or image format conversions done from inside the assistant without opening a separate web tool, for example turning a downloaded PDF into Word, combining several PDFs, or converting phone photos.
Requirements: Runs locally via npx from the npm package convertica-mcp (Node.js needed). Requires a Convertica API key in the CONVERTICA_API_KEY environment variable, obtained from a paid Convertica subscription. Network access is needed because conversions run over HTTPS.

Before you install

The API key is a secret passed in the environment; keep it out of shared configs. Conversions are metered against a monthly plan quota, so usage may cost money. Input files are uploaded to Convertica's servers for processing, though the README says they are deleted after the response. Results are written to local disk next to the input unless output_dir is set.

Installation

In SourceWeft

Open Convertica in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MCP tools

The server exposes two tools.

list_converters

Lists all 35+ Convertica converters with their file fields and options. Call this first to find the right tool slug for convert_file. Takes no input.

convert_file

Runs one of convertica.net's 35+ conversion tools on local file(s) and saves the result next to the input (or into output_dir). Requires authentication via the CONVERTICA_API_KEY env var.

Usage notes

Files are read from and written to your local disk; results are saved next to the input file unless you pass output_dir.
Conversions run synchronously over HTTPS; processed files are deleted from Convertica's servers right after the response (details).
API calls are metered against your plan's monthly quota; failed calls are not counted.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
