Setup & Configuration

Prerequisites

A Kasar CRM account with an active subscription
An API token created in Settings > API

Create an API Token

Open your Kasar workspace and navigate to Settings > API
Click Create Token
Give it a name (e.g., "Claude Desktop")
Select the required scopes:
- mcp — full CRM access (records, schema, pipelines, tasks, notes)
- inbox:content — email body access (required for inbox tools)
Copy the token (ksr_...) — it will only be shown once

Treat your API token like a password. Never commit it to version control or share it publicly. If compromised, revoke it immediately in Settings and create a new one.

Claude Desktop

Add the following to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "kasar": {
      "url": "https://kasar.app/api/mcp/sse",
      "headers": {
        "Authorization": "Bearer ksr_..."
      }
    }
  }
}

Replace ksr_... with your actual API token.

After saving, restart Claude Desktop. You should see the Kasar tools appear in the tools menu.

Cursor

Add the MCP server in your Cursor settings:

Open Cursor Settings > MCP
Click Add MCP Server
Configure:

{
  "mcpServers": {
    "kasar": {
      "url": "https://kasar.app/api/mcp/sse",
      "headers": {
        "Authorization": "Bearer ksr_..."
      }
    }
  }
}

Other MCP Clients

Any client that supports the Streamable HTTP transport can connect. Provide:

Parameter	Value
URL	`https://kasar.app/api/mcp/sse`
Transport	Streamable HTTP (SSE)
Auth Header	`Authorization: Bearer ksr_...`

Token Scopes

Scope	Access
`mcp`	Full CRM access — records, schema, pipelines, tasks, notes, aggregations
`inbox:content`	Email body and attachment metadata — required for the `search_emails` and `draft_email` tools

The mcp scope is required for all MCP operations. Add inbox:content only if you want AI assistants to read and draft emails on your behalf.

Verify the Connection

Once configured, ask your AI assistant:

"List all objects in my Kasar CRM"

The assistant should read the kasar://schema resource and return a list of your CRM objects (contacts, companies, opportunities, etc.). If you see an authentication error, double-check your token and endpoint URL.
