Svara is a REST API for sending voice notes on LinkedIn. This server exposes it as MCP tools, so your AI assistant can upload a recording, validate a send, deliver a voice note to one of your LinkedIn contacts, and check whether it arrived.

What it does

Upload an audio file (MP3, M4A/AAC, OGG/Opus, WAV or WebM, up to 4 MB).
Send it as a native LinkedIn voice note to someone you can already message on LinkedIn.
Check delivery status (queued, sent, failed, expired).
Check your plan usage.

Sends are dry runs by default: nothing is delivered unless dry_run is explicitly set to false.

Prerequisites

A Svara account and an API key: create one at https://svarapi.io/dashboard.
The Svara Chrome extension installed.
You are signed in to LinkedIn in that Chrome browser.
Node.js 20 or newer (for npx).

Setup

All clients run the same command: npx -y svara-mcp with SVARA_API_KEY in the environment.

Claude Desktop

Add to claude_desktop_config.json (Settings > Developer > Edit Config):

{
  "mcpServers": {
    "svara": {
      "command": "npx",
      "args": ["-y", "svara-mcp"],
      "env": { "SVARA_API_KEY": "your_svara_api_key" }
    }
  }
}

Claude Code

claude mcp add svara --env SVARA_API_KEY=your_svara_api_key -- npx -y svara-mcp

Cursor

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "svara": {
      "command": "npx",
      "args": ["-y", "svara-mcp"],
      "env": { "SVARA_API_KEY": "your_svara_api_key" }
    }
  }
}

VS Code

Add to .vscode/mcp.json:

{
  "inputs": [
    { "type": "promptString", "id": "svara-api-key", "description": "Svara API key", "password": true }
  ],
  "servers": {
    "svara": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "svara-mcp"],
      "env": { "SVARA_API_KEY": "${input:svara-api-key}" }
    }
  }
}

Tools

Tool	What it does
`upload_audio`	`{ file_path }` Uploads a local audio file and returns an `audio_url`. Sends nothing.
`send_linkedin_voice_note`	`{ recipient, audio_url? , file_path?, dry_run = true }` Sends a voice note. `recipient` is a LinkedIn profile URL (preferred) or name. Give exactly one of `audio_url` or `file_path` (a file is uploaded first).
`get_send_status`	`{ id }` Delivery status of a send.
`get_usage`	`{}` Current plan usage and limits.

Example prompt: "Upload ~/Desktop/intro.m4a and do a dry run of sending it to https://www.linkedin.com/in/example. If it validates, send it for real."

Safety

send_linkedin_voice_note sends a real LinkedIn message to a real person from your own LinkedIn account when dry_run is false. It cannot be unsent.

dry_run defaults to true, which validates the request without sending anything.
The tool is marked as destructive, so MCP clients that support tool annotations will ask you to confirm before it runs. Keep that confirmation on.
Only send to people you can already message on LinkedIn, and only messages you would send yourself.
