Sunsama MCP Server

A Model Context Protocol (MCP) server that provides comprehensive task management capabilities through the Sunsama API. This server enables AI assistants to access Sunsama tasks, create new tasks, mark tasks complete, and manage your productivity workflow.

Features

Task Management

• Create Tasks - Create new tasks with notes, time estimates, due dates, stream assignments, and GitHub/Gmail integrations
• Read Tasks - Get tasks by day with completion filtering, access backlog tasks, retrieve archived task history
• Update Tasks - Mark tasks as complete with custom timestamps, reschedule tasks or move to backlog
• Subtasks - Add, update, complete, and manage subtasks within tasks
• Delete Tasks - Permanently remove tasks from your workspace

User & Stream Operations

• User Information - Access user profile, timezone, and group details
• Stream Management - Get streams/channels for project organization
• Dual Transport - Support for both stdio and HTTP stream MCP transports

Installation

Prerequisites

• Bun runtime (for development)
• Sunsama account with API access

Using NPX (Recommended)

No installation required! Use directly with:

npx mcp-sunsama

Development Setup

1. Clone the repository:

git clone https://github.com/robertn702/mcp-sunsama.git
cd mcp-sunsama

2. Install dependencies:

bun install

3. Set up your environment variables:

cp .env.example .env
# Edit .env and add your Sunsama credentials

Environment variables:

• SUNSAMA_EMAIL - Your Sunsama account email (required for stdio transport)
• SUNSAMA_PASSWORD - Your Sunsama account password (required for stdio transport)
• TRANSPORT_MODE - Transport type: stdio (default) or http
• PORT - Server port for HTTP transport (default: 8080)
• HTTP_ENDPOINT - MCP endpoint path (default: /mcp)
• SESSION_TTL - Session timeout in milliseconds (default: 3600000 / 1 hour)
• CLIENT_IDLE_TIMEOUT - Client idle timeout in milliseconds (default: 900000 / 15 minutes)
• MAX_SESSIONS - Maximum concurrent sessions for HTTP transport (default: 100)

Usage

Transport Modes

This server supports two transport modes:

Stdio Transport (Default)

For local AI assistants (Claude Desktop, Cursor, etc.):

bun run dev
# or
TRANSPORT_MODE=stdio bun run src/main.ts

HTTP Stream Transport

For remote access and web-based integrations:

TRANSPORT_MODE=http PORT=8080 bun run src/main.ts

HTTP Endpoints:

• MCP Endpoint: POST http://localhost:8080/mcp
• Health Check: GET http://localhost:8080/

Authentication: HTTP requests require HTTP Basic Auth with your Sunsama credentials:

curl -X POST http://localhost:8080/mcp \
  -H "Authorization: Basic $(echo -n 'your-email:your-password' | base64)" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'

Claude Desktop Configuration

Add this configuration to your Claude Desktop MCP settings:

{
  "mcpServers": {
    "sunsama": {
      "command": "npx",
      "args": ["mcp-sunsama"],
      "env": {
        "SUNSAMA_EMAIL": "your-email@example.com",
        "SUNSAMA_PASSWORD": "your-password"
      }
    }
  }
}

Claude Code Configuration

Add the Sunsama MCP server using the Claude Code CLI:

claude mcp add sunsama --scope user \
  -e SUNSAMA_EMAIL=your-email@example.com \
  -e SUNSAMA_PASSWORD=your-password \
  -- npx mcp-sunsama

Scope Options:

• --scope user - Available across all projects (recommended)
• --scope project - Only available in the current project

After adding the server, restart Claude Code to connect to the Sunsama MCP server.

Integration Examples

The create-task tool supports linking tasks to external services like GitHub and Gmail.

GitHub Integration

Link a task to a GitHub issue:

{
  "text": "Fix authentication bug",
  "integration": {
    "service": "github",
    "identifier": {
      "id": "I_kwDOO4SCuM7VTB4n",
      "repositoryOwnerLogin": "robertn702",
      "repositoryName": "mcp-sunsama",
      "number": 42,
      "type": "Issue",
      "url": "https://github.com/robertn702/mcp-sunsama/issues/42",
      "__typename": "TaskGithubIntegrationIdentifier"
    },
    "__typename": "TaskGithubIntegration"
  }
}

Link a task to a GitHub pull request:

{
