What you can do with Speechmatics in Claude and ChatGPT

For teams who turn audio and video recordings into text with Speechmatics.

Transcribe a recording from a link

The AI submits a public audio or video URL for transcription, optionally with speaker labels, translation and a summary. It then checks the job until it is done.

Changes data

Get the transcript of a finished job

The AI fetches a done job's transcript as plain text, subtitles (SRT) or structured JSON with words, timings and speakers.

Check which jobs are done

The AI lists your recent transcription jobs, newest first, with status, name and duration. You see what finished and what is still running.

Find out why a job was rejected

The AI reads the job status and the plain-text processing log of a job. You get the reason it failed.

Check the transcription minutes used

The AI reads usage statistics, in transcription minutes, over a date range you choose.

Delete a job and its transcript

The AI permanently deletes a job and its transcript, and can force the delete while a job is still running.

How do I connect Speechmatics?

Before you connect

The login page asks for your Speechmatics API key.

Find it in the Speechmatics Portal → API Keys. Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Speechmatics and this URL, then click Add:
    https://speechmatics.usefulapi.io/mcp
  3. Claude opens the login page: enter your Speechmatics API key.
  4. In a chat, click + → Connectors and turn on Speechmatics.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Speechmatics and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://speechmatics.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Speechmatics API key.
  4. In Plugins, install Speechmatics, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http speechmatics https://speechmatics.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "speechmatics": {
      "url": "https://speechmatics.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "speechmatics": {
      "type": "http",
      "url": "https://speechmatics.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add speechmatics --url https://speechmatics.usefulapi.io/mcp
codex mcp login speechmatics

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

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: the login page asks for your Speechmatics API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Each paid plan covers this Speechmatics server only. Ask your AI to run speechmatics_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with speechmatics_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with speechmatics_upgrade before then undoes the cancel.

Your usefulapi plan · 4

  • Usage status (free-tier meter)speechmatics_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featurespeechmatics_request_feature
    Tell usefulapi that the user needs something the Speechmatics tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+speechmatics_upgrade
    Get a paid plan for Speechmatics (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionspeechmatics_cancel_subscription
    Cancel the caller's Speechmatics Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run speechmatics_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Speechmatics in Claude or ChatGPT?

Transcribe a recording from a link. Get the transcript of a finished job. Check which jobs are done. Find out why a job was rejected. Check the transcription minutes used. Delete a job and its transcript. See what you can do for the details.

Is this an official Speechmatics product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Speechmatics. The server calls the Speechmatics API with your own Speechmatics access, so it sees only the data that your account can see.

Can I connect Speechmatics to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Speechmatics API key. See Before you connect for where to find it.

Do I put my Speechmatics key or an Authorization header in the client config?

No. 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: the login page asks for your Speechmatics API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Speechmatics credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Speechmatics API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Speechmatics.

Can the AI change my Speechmatics data?

Yes, if you approve it. 2 of the 7 Speechmatics tools can create or change data. The other 5 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Speechmatics server only. Cancel any time: your paid plan then runs to the end of the paid period. Run speechmatics_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run speechmatics_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run speechmatics_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Speechmatics tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with speechmatics_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
