• MCP_AUTH_TOKEN: Admin authentication token (optional)
• BASE_URL: Base URL for email verification links (optional)

• GET / - API documentation and status
• GET /health - Health check endpoint
• POST /register - User registration (no auth required)
• GET /verify?token=... - Email verification (no auth required)
• POST /mcp - Main MCP protocol endpoint (conditional auth)
• GET /tools - List available tools (conditional auth)

# Register via HTTP endpoint
curl -X POST https://your-server.com/register \
  -H "Content-Type: application/json" \
  -d '{"email": "user@example.com"}'

# Or via MCP (no auth required)
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "register_user",
    "arguments": {
      "email": "user@example.com"
    }
  }
}

Check your email and click the verification link, or visit:

https://your-server.com/verify?token=YOUR_VERIFICATION_TOKEN

Use the access token from the verification page in the Authorization header:

curl -X POST https://your-server.com/mcp \
  -H "Authorization: YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "tools/list"}'

Create AI-enhanced thought forks that automatically generate multiple perspectives:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_thought_fork",
    "arguments": {
      "title": "AI Ethics in Healthcare",
      "description": "Explore the ethical implications of AI in medical diagnosis and treatment",
      "branches": 4
    }
  }
}

This will:

1. Create a thought fork
2. Generate 4 different analytical perspectives using AI
3. Create parallel explorations for each perspective
4. Extract key insights from each exploration
5. Return the complete thought fork with all explorations

Merge the explorations with AI synthesis:

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "merge_thought_fork",
    "arguments": {
      "id": "thought-fork-id"
    }
  }
}

The blob storage system provides secure, user-namespaced key-value storage for arbitrary data:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "blob_set",
    "arguments": {
      "key": "user-preferences",
      "value": {
        "theme": "dark",
        "language": "en",
        "notifications": true
      }
    }
  }
}

Retrieve stored data:

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "blob_get",
    "arguments": {
      "key": "user-preferences"
    }
  }
}

List all your stored blobs:

{
  "jsonrpc": "2.0",
  "id": 3,
  "method": "tools/call",
  "params": {
    "name": "blob_list",
    "arguments": {
      "prefix": "config-"
    }
  }
}

• Automatic Namespacing: All blob keys are automatically prefixed with your user ID
• JSON Support: Automatic JSON serialization/deserialization (can be disabled)
• Prefix Filtering: List blobs with specific prefixes
• Existence Checking: Check if a blob exists without retrieving its value
• Admin Access: Admin users can access global blob storage
• Secure Isolation: Users can only access their own blobs

All resources support full deletion with dependency handling:

• Goals: Deleting a goal removes all subgoals and associated tasks
• Tasks: Deleting a task removes it from goals and other task dependencies
• Thought Forks: Deleting removes all associated explorations
• Skills: Deleting removes all execution history
• States: Direct deletion of cognitive states

• Obtained through email verification
• Scoped to user's own resources
• Required for all cognitive tools

• Set via MCP_AUTH_TOKEN environment variable
• Access to legacy global resources
• Full system access

• User registration tools only
• No authentication required

• register_user - Register with email
• verify_email - Verify email with token

• Blob Storage: blob_list, blob_get, blob_set, blob_delete, blob_exists
• Thought Forking: create_thought_fork, merge_thought_fork, delete_thought_fork
• Goals: create_goal, update_goal, delete_goal, list_goals
• Tasks: create_task, update_task, delete_task, list_tasks

• Skills: create_skill, execute_skill, delete_skill, list_skills

• skill_[name] - Execute user-created skills dynamically

1. Register: register_user with email
2. Verify: Click email link to get access token
3. Store Data: Use blob_set to store configuration or data
4. Create Goal: Use create_goal to set objectives
5. Fork Thoughts: Use create_thought_fork for AI-assisted analysis
6. Merge Insights: Use merge_thought_fork for AI synthesis
7. Create Tasks: Break down goals with create_task
8. Build Skills: Create reusable tools with create_skill
9. Save State: Capture progress with save_cognitive_state

• Email verification required for access
• User-scoped resource isolation
