Overview

AI-generated overview

Hosted Speechmatics server that lets an assistant submit audio or video for speech-to-text and fetch transcripts, job status, logs and usage.

What you can do
  • Submit a public audio or video URL for transcription, optionally with diarization, translation and summarization
  • List recent jobs and check a single job's status, polling until it is done
  • Retrieve a finished transcript as plain text, SRT subtitles or structured JSON with words, timings and speakers
  • Read a job's processing log to debug rejected jobs
  • Check transcription minutes used over a date range
  • Delete a job and its transcript, optionally forcing deletion of a running job
When to use it
Useful when you want transcripts, subtitles or speaker-labelled text from recordings without running transcription locally, and want to check job status or account usage from the same chat.
Requirements
Remote MCP endpoint connected by URL only; no local install. Sign-in uses OAuth, and the login page asks for your Speechmatics API key, which is validated and stored per user. The audio or video must be at a publicly reachable URL. Free plan allows 50 tool calls per month.
Before you install
The server asks for your Speechmatics API key during OAuth login; the README says not to put it in the client config. Submitting a URL sends that media to Speechmatics for processing. Deleting a job permanently removes it and its transcript, and force=true deletes even a running job. Paid plans are billed through a Stripe checkout link, and cancellation gives no refund for the current period.

Installation

In SourceWeft

  1. Open Speechmatics MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fspeechmatics/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

Speechmatics MCP by usefulapi

Transcribe audio and video with speaker diarization, translation, and summarization from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Speechmatics API key.

Live endpoint: https://speechmatics.usefulapi.io/mcp · Homepage: https://usefulapi.io/speechmatics

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://speechmatics.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http speechmatics https://speechmatics.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "speechmatics": {      "url": "https://speechmatics.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Speechmatics credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/speechmatics/

On first connect you'll paste your Speechmatics API key. It's validated, stored per-user, and scoped to you.
