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, and stream assignments
• 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
• 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

1. Install dependencies:

bun install

1. 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": "[email protected]",
        "SUNSAMA_PASSWORD": "your-password"
      }
    }
  }
}

Development

Running in Development

bun run dev

Testing with MCP Inspector

bun run inspect

Then connect the MCP Inspector to test the tools interactively.

Testing

bun test                   # Run unit tests only
bun test:unit              # Run unit tests only (alias)
bun test:integration       # Run integration tests (requires credentials)
bun test:all               # Run all tests
bun test:watch             # Watch mode for unit tests

Build and Type Checking

bun run build              # Compile TypeScript to dist/
bun run typecheck          # Run TypeScript type checking
bun run typecheck:watch    # Watch mode type checking

Release Process

For information on creating releases and publishing to npm, see CONTRIBUTING.md.
