Svara

Svara MCP server

Send native LinkedIn voice notes from Claude, Cursor, VS Code or any other MCP client.

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

1. A Svara account and an API key: create one at https://svarapi.io/dashboard.
2. The Svara Chrome extension installed.
3. You are signed in to LinkedIn in that Chrome browser.
4. 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

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.

Pricing
