Convertr MCP

An official MCP server provided by Convertr that allows AI agents to interact with the Convertr file conversion API. It exposes tools for listing supported formats, converting files, retrieving conversion status, deleting conversions, and checking account details, enabling automated media and document processing.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Convertr (https://convertr.org) converts files between more than 800 format pairs: video, audio, images, documents, e-books, archives and more. Typical flow: 1. list_formats (optionally with input_format) to check that a conversion exists. 2. convert_file with a public url or with content_base64 (max 10 MB) and the output_format. The call waits for the result. 3. If the status is still queued or processing, call get_conversion with the id until it is succeeded or failed. 4. Give the user the download_url of the finished conversion. Pricing: 1 credit per conversion of an input up to 100 MB. Every account gets 100 free credits per month. Failed conversions are refunded. Buy more credits at https://convertr.org/pricing. Privacy: files and results are deleted after 24 hours. delete_conversion removes them earlier. Auth: list_formats works without a key. All other tools need an API key. Create a free account at https://convertr.org/register, open the API page in the dashboard and copy your key (it starts with cvk_). Send it as the header `X-API-Key: <key>` or `Authorization: Bearer <key>`, or add `?api_key=<key>` to the MCP URL.

convert_file — Convert a file
Advertised by the server during the last successful anonymous check.
Open-world

Convert a file to another format. Give exactly one of url (public link to the file) or content_base64 (file content, max 10 MB), plus output_format. The call waits up to wait_seconds (default 50, max 80) for the result. When the status is succeeded, the answer contains the download_url and the time it expires (files are deleted after 24 hours). When the status is queued or processing, call get_conversion with the id. Costs 1 credit per conversion of an input up to 100 MB (100 free credits per month); failed conversions are refunded. Needs an API key.

list_formats — List supported formats
Advertised by the server during the last successful anonymous check.
Advertised read-only

List what Convertr can convert. Without input_format it returns all supported input formats (short list). With input_format (for example mp4) it returns every output format for that input, with its group (Audio, Video, Image, Document ...). Use it to check that a conversion exists before you call convert_file. Works without an API key.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Cursor

Merge this server into .cursor/mcp.json in your project, then enable convertr-mcp in your MCP settings.
