Connect Voxec to Claude

Last updated 24 October 2026.

Add Voxec to Claude as a custom connector so Claude can place phone calls for you. It takes about two minutes. You sign in to Voxec; there's no key to copy.

Before you start

  • A Voxec account. Voxec is in closed beta: request access on the home page.
  • Any Claude plan. Custom connectors work on Free, Pro, Max, Team and Enterprise. Free accounts can have one custom connector.
  • Use a computer for setup. Add Voxec on claude.ai or in Claude Desktop (the steps are the same). Once added, it's there in the Claude iOS and Android apps too.
  • On a Team or Enterprise plan, an Owner adds it first: see Team and Enterprise.

Add Voxec on claude.ai

  1. Step 1: Copy the Voxec address and open Connectors

    Copy this address:

    https://mcp.voxec.ai/mcp

    Then open Customize → Connectors (opens in a new tab) in Claude (in Claude Desktop: Customize → Connectors) and click + Add.

  2. Step 2: Choose Add custom connector

    Click Add custom connector. If your menu shows Custom instead, hover over it and choose Web: Claude is moving to this wording, and it leads to the same form.

  3. Step 3: Name it Voxec and paste the address

    Enter Voxec as the name, paste the address as the remote MCP server URL, and click Continue. If Claude shows the sign-in settings it detected, click Continue again.

  4. Step 4: Keep the sign-in settings and click Add

    Under Authentication, choose Sign in now (or Sign in when needed). Under OAuth client, keep Use Claude's published identity (Recommended). Leave Request headers empty. Click Add.

    Don't choose Register automatically or Use your own OAuth client: Voxecsigns Claude in by its published identity only, and the other options end at a “This connection request is not valid” page.

  5. Step 5: Connect, and sign in to Voxec

    Claude opens Voxec in a new tab or window. If it doesn't, click Connect next toVoxec in the connectors list. Sign in to Voxec if asked.

  6. Step 6: Check the request and click Allow

    Voxec's page should say Allow Claude to place calls as you? and that you'll be sent back to claude.ai. Check the email address it's signed in as (Not you? switches account), then click Allow. You're sent back to Claude, and Voxec emails you a note of the connection.

    If it names a different app or address, click Cancel: you didn't start that request from Claude.

Use it in a chat

  1. Step 7: Switch Voxec on in the chat

    In a new chat, click + at the bottom left of the message box (or type /), go to Connectors and make sure Voxec is switched on. On the mobile apps, use the same + menu.

    Then ask for a call, for example “Call Luigi's on +44 20 7946 0123 and book a table for two this Friday at 7:30pm.” The first time Claude uses a Voxec tool it may ask your permission: allow it to go ahead.

Team and Enterprise plans

Only an Owner (or, on Enterprise, someone whose role can manage connectors) can add a custom connector for the organisation:

  1. Open Organization settings → Connectors.
  2. Click Add, hover over Custom and choose Web.
  3. Name it Voxec, enter https://mcp.voxec.ai/mcp, click Continue, keep Use Claude's published identity (Recommended) and click Add. Leave request headers empty: Voxec has no shared key, so each member signs in as themselves.

Members then open Customize → Connectors (opens in a new tab), find Voxec (labelled Custom), click Connect and sign in to their own Voxecaccount (steps 5 and 6 above).

Claude Code

  1. Step 1: Add Voxec from your terminal

    Run this in your terminal:

    claude mcp add --transport http voxec https://mcp.voxec.ai/mcp

  2. Step 2: Authenticate from /mcp

    Start Claude Code, type /mcp, pick voxec and choose Authenticate. Your browser opens Voxec. The page asks to Allow Claude Code to place calls as you? and warns that the app runs on your own computer, because it sends you back to localhost. Only click Allow if you just started this yourself.

Already added Voxec on claude.ai? It also appears in Claude Code when you're signed in with the same Claude account, marked as coming from claude.ai. Scripts and other MCP clients that send a key instead of signing in can use an API key from the Connect page.

Troubleshooting

  • “This connection request is not valid” on a Voxec page: the connector was added with the wrong sign-in option. Remove Voxec in Claude and add it again (Claude can't edit a custom connector), keeping Use Claude's published identity (Recommended), and check the address is exactly https://mcp.voxec.ai/mcp.
  • Claude says it can't connect, or Voxec stops working: open Customize → Connectors, choose Voxec and connect again. If you disconnected Claude on Voxec's Connect page, this is expected: reconnect the same way. In Claude Code, use /mcp → voxec → Re-authenticate.
  • “Verify your email first”: open the verification email Voxec sent you, then click Connect in Claude again.
  • Signed in to the wrong Voxec account: on the consent page click Not you?, sign in with the right account and carry on.
  • Claude doesn't use Voxec: check Voxec is switched on in the chat's + → Connectors menu, and give the number and what you want the call to achieve.
  • “This request has expired”: the sign-in took more than ten minutes. Go back to Claude and click Connect again.

Disconnecting

  • In Claude: open Customize → Connectors (opens in a new tab), choose Voxec, and disconnect it, or remove it with Remove or the … menu.
  • In Claude Code: run claude mcp remove voxec (this also deletes the stored sign-in).
  • From Voxec: on the Connect page, under Connected apps, click Disconnect next to Claude. Access stops within a minute.

Disconnecting doesn't delete your calls.
