What you can do with Rev.ai in Claude and ChatGPT
For developers and teams who turn audio and video into text with Rev.ai.
Submit a recording for transcription
The AI starts a machine transcription job for an audio or video file at a public URL. It uses your Rev.ai credit.
Changes dataCheck recent jobs and their status
The AI lists jobs of the last 30 days with status, name, duration, language and failure reason, and opens one job by id.
Read a transcript with speakers and times
The AI reads a finished job's transcript as plain text with speaker labels, or as segments with speaker, start and end. It can summarize it.
Get captions or a summary of a finished job
The AI fetches captions as SRT or WebVTT, and the summary when the job was submitted with a summarization type.
Check credit balance and delete old jobs
The AI reads your balance and the account details. It can delete a finished job with its media and transcript for good.
Changes dataHow do I connect Rev.ai?
Before you connect
The login page asks for your Rev.ai access token.
Create one at rev.ai → Access Token → Generate New Access Token (an account can hold 2 tokens). Rev.ai shows a token only once, so copy it right away. Your token is used only to call the Rev.ai API on your behalf; it is never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"rev-ai": {
"url": "https://rev-ai.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"rev-ai": {
"type": "http",
"url": "https://rev-ai.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
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.
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 Rev.ai access token. 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.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Rev.ai server only. Ask your AI to run revai_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 revai_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 revai_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- Get account and balance
revai_get_accountThe Rev.ai account behind the token: email, free, purchased, total and invoiced balance (USD) and whether HIPAA is on. - List transcription jobs
revai_list_jobsList transcription jobs from the last 30 days, newest first: id, status (in_progress, transcribed, failed), name, duration, language, failure reason. Page with starting_after = the previous reply's next_starting_after. - Get job status
revai_get_jobOne transcription job by id: status (in_progress, transcribed, failed), timestamps, duration, language, failure reason. Poll this until status is transcribed. - Get transcript
revai_get_transcriptThe transcript of a transcribed job. format=text (default) is plain text with speaker labels and timestamps; format=segments is a list of {speaker, start, end, text} per speaker turn (seconds). Long transcripts are paged: repeat with next_offset until it is null. - Get transcript summary
revai_get_summaryThe summary of a transcribed job. It exists only if the job was submitted with summarization_type. Paged by character like revai_get_transcript. - Get captions

- Submit transcription job
revai_submit_jobWRITE: start an asynchronous machine transcription job for an audio or video file at a public URL. It uses Rev.ai credit (free credit first).

revai_delete_jobWRITE: permanently delete a finished (transcribed or failed) job with its media and transcript. This cannot be undone. A job still in progress cannot be deleted.
Your usefulapi plan · 4
- Usage status (free-tier meter)
revai_usage_statusReport 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 feature
revai_request_featureTell usefulapi that the user needs something the Rev.ai 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+
revai_upgradeGet a paid plan for Rev.ai (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: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. 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 subscription
revai_cancel_subscriptionCancel the caller's Rev.ai 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 revai_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Rev.ai in Claude or ChatGPT?
Submit a recording for transcription. Check recent jobs and their status. Read a transcript with speakers and times. Get captions or a summary of a finished job. Check credit balance and delete old jobs. See what you can do for the details.
Is this an official Rev.ai product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Rev.ai. The server calls the Rev.ai API with your own Rev.ai access, so it sees only the data that your account can see.
Can I connect Rev.ai 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 Rev.ai access token. See Before you connect for where to find it.
Do I put my Rev.ai 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 Rev.ai access token. 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 Rev.ai credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Rev.ai 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 Rev.ai.
Can the AI change my Rev.ai data?
Yes, if you approve it. 2 of the 8 Rev.ai tools can create or change data. The other 6 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 Rev.ai server only. Cancel any time: your paid plan then runs to the end of the paid period. Run revai_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run revai_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 revai_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Rev.ai tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with revai_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.
