+# MCP Server Examples
+
+Examples demonstrating the MCP Server v2 features per MCP Protocol Version 2025-11-25.
+
+## Features Demonstrated
+
+### 1. Pagination (`pagination_example.py`)
+
+Demonstrates pagination for `tools/list`, `resources/list`, and `prompts/list`:
+
+- Opaque cursor encoding (base64url)
+- Server-determined page size (default: 50, max: 100)
+- `nextCursor` for fetching more results
+- Cursor validation with JSON-RPC errors
+
+```bash
+python pagination_example.py
+```
+
+### 2. Tool Annotations (`tool_annotations_example.py`)
+
+Demonstrates MCP 2025-11-25 tool annotation hints:
+
+- `readOnlyHint`: Tool only reads data
+- `destructiveHint`: Tool may have destructive effects
+- `idempotentHint`: Safe to call multiple times
+- `openWorldHint`: Interacts with external world
+
+```bash
+python tool_annotations_example.py
+```
+
+### 3. CLI Tools (`cli_tools_example.sh`)
+
+Demonstrates the new CLI commands:
+
+```bash
+# List tools with pagination
+praisonai mcp list-tools --limit 10
+praisonai mcp list-tools --cursor <cursor> --json
+
+# Search tools
+praisonai mcp tools search "query"
+praisonai mcp tools search --category memory
+praisonai mcp tools search --read-only
+praisonai mcp tools search --json
+
+# Get tool info
+praisonai mcp tools info <tool-name>
+praisonai mcp tools info <tool-name> --json
+
+# Get tool schema
+praisonai mcp tools schema <tool-name>
+```
+
+## API Reference
+
+### Pagination
+
+```python
+from praisonai.mcp_server.registry import MCPToolRegistry
+
+registry = MCPToolRegistry()
+# ... register tools ...
+
+# Get first page
+tools, next_cursor = registry.list_paginated(page_size=50)
+
+# Get next page
+if next_cursor:
+    more_tools, next_cursor = registry.list_paginated(cursor=next_cursor)
+```
+
+### Tool Search
+
+```python
+# Search by query
+tools, next_cursor, total = registry.search(query="memory")
+
+# Filter by category
+tools, _, _ = registry.search(category="file")
+
+# Filter by read-only hint
+tools, _, _ = registry.search(read_only=True)
+
+# Combined filters with pagination
+tools, next_cursor, total = registry.search(
+    query="data",
+    category="storage",
+    read_only=True,
+    page_size=10,
+)
+```
+
+### Tool Annotations
+
+```python
+from praisonai.mcp_server.registry import MCPToolDefinition
+
+# Read-only tool
+tool = MCPToolDefinition(
+    name="data.read",
+    description="Read data",
+    handler=read_handler,
+    input_schema={"type": "object"},
+    read_only_hint=True,
+    destructive_hint=False,
+)
+
+# Destructive tool
+tool = MCPToolDefinition(
+    name="file.delete",
+    description="Delete file",
+    handler=delete_handler,
+    input_schema={"type": "object"},
+    destructive_hint=True,
+    idempotent_hint=False,
+)
+```
+
+## MCP Protocol Compliance
+
+These examples comply with MCP Protocol Version 2025-11-25:
+
+- Pagination uses opaque cursors (base64url encoded)
+- Server determines page size (client cannot override)
+- Invalid cursors return JSON-RPC error code -32602
+- Tool annotations follow the spec defaults:
+  - `readOnlyHint`: false
+  - `destructiveHint`: true
+  - `idempotentHint`: false
+  - `openWorldHint`: true

+# PraisonAI MCP Server Examples
+
+This directory contains examples for running PraisonAI as an MCP (Model Context Protocol) server.
+
+## Overview
+
+PraisonAI can expose its capabilities via MCP protocol, allowing integration with:
+- Claude Desktop
+- Cursor
+- Windsurf
+- VSCode MCP clients
+- Any MCP-compatible client
+
+## Protocol Version
+
+These examples use MCP Protocol Version **2025-11-25**.
+
+## Examples
+
+### 1. STDIO Server (stdio_server.py)
+
+Run PraisonAI as an MCP server using STDIO transport (for Claude Desktop integration).
+
+```bash
+# Run directly
+python stdio_server.py

+# Package Manager Example
+
+This example demonstrates how to use the PraisonAI package manager for installing and managing Python packages with security defaults.
+
+## Features Demonstrated
+
+- Installing packages with version constraints
+- Listing installed packages
+- Searching for packages on PyPI
+- Managing package index configuration
+- Security features (dependency confusion prevention)
+
+## Quick Start
+
+```bash
+# Run the example
+python package_manager_example.py
+```
+
+## CLI Commands
+
+### Install Packages
+
+```bash
+# Install a package
+praisonai install requests
+
+# Install with version constraint
+praisonai install "requests>=2.28"
+
+# Install multiple packages
+praisonai install requests httpx aiohttp
+
+# Upgrade existing package
+praisonai install requests --upgrade
+
+# JSON output
+praisonai install requests --json
+```
+
+### Uninstall Packages
+
+```bash
+# Uninstall a package
+praisonai uninstall requests
+
+# Uninstall without confirmation
+praisonai uninstall requests --yes
+```
+
+### List Packages
+
+```bash
+# List all installed packages
+praisonai package list
+
+# JSON output
+praisonai package list --json
+```
+
+### Search Packages
+
+```bash
+# Search PyPI
+praisonai package search langchain
+
+# JSON output
+praisonai package search langchain --json
+```
+
+### Index Configuration
+
+```bash
+# Show current index settings
+praisonai package index show --json
+
+# Set custom index
+praisonai package index set https://pypi.mycompany.com/simple
+
+# Reset to PyPI default
+praisonai package index set https://pypi.org/simple
+```
+
+## Security Features
+
+By default, only the primary index (PyPI) is used. Extra indexes are blocked to prevent dependency confusion attacks.
+
+```bash
+# This will FAIL (extra index not allowed by default)
+praisonai install mypackage --extra-index-url https://other.index.com/simple
+
+# Explicitly allow extra index (shows security warning)
+praisonai install mypackage \
+  --extra-index-url https://other.index.com/simple \
+  --allow-extra-index
+```
+
+## Environment Variables
+
+- `PRAISONAI_PACKAGE_INDEX_URL` - Override primary index URL
+- `PIP_INDEX_URL` - Fallback to pip's index URL

 # Recipe Registry Example
 
-This example demonstrates how to use the PraisonAI recipe registry for publishing and pulling recipes.
+This example demonstrates how to use the PraisonAI recipe registry for publishing and pulling recipes via both local filesystem and HTTP server.
 
 ## Features Demonstrated
 
 - Creating a local registry
-- Packing recipes into bundles
-- Publishing recipes to the registry
+- Starting an HTTP registry server
+- Publishing recipes with token authentication
 - Listing and searching recipes
-- Pulling recipes from the registry
+- Pulling recipes from HTTP registry
 
 ## Quick Start
 
 ```bash
-# Run the example
-python registry_example.py
+# Run the HTTP registry example
+python http_registry_example.py
 ```
 
-## CLI Commands
+## HTTP Registry Server
 
 ```bash
-# Publish a recipe
+# Start HTTP registry server
+praisonai registry serve --port 7777
+
+# Start with authentication
+praisonai registry serve --port 7777 --token mysecret
+
+# Check server status
+praisonai registry status --registry http://localhost:7777
+```
+
+## CLI Commands with HTTP Registry
+
+```bash
+# Publish to HTTP registry
+praisonai recipe publish ./my-recipe --registry http://localhost:7777 --json
+
+# Publish with token
+praisonai recipe publish ./my-recipe --registry http://localhost:7777 --token mysecret
+
+# Pull from HTTP registry
+praisonai recipe pull [email protected] --registry http://localhost:7777 -o ./recipes
+
+# List recipes from HTTP registry
+praisonai recipe list --registry http://localhost:7777 --json
+
+# Search HTTP registry
+praisonai recipe search "hello" --registry http://localhost:7777
+```
+
+## Local Registry Commands
+
+```bash
+# Publish to local registry (default)
 praisonai recipe publish ./my-recipe --json
 
-# Pull a recipe
+# Pull from local registry
 praisonai recipe pull [email protected] -o ./recipes
 
-# List recipes in registry
-praisonai recipe list --json
-
-# Search recipes
-praisonai recipe search "hello"
-```
-
-## Using a Custom Registry Path
-
-```bash
-# Publish to custom registry
+# Use custom local path
 praisonai recipe publish ./my-recipe --registry /path/to/registry
-
-# Pull from custom registry
-praisonai recipe pull [email protected] --registry /path/to/registry
 ```
 
+## Environment Variables
+
+- `PRAISONAI_REGISTRY_TOKEN` - Default token for HTTP registry authentication
+
 ## Default Registry Location
 
-By default, the registry is stored at `~/.praison/registry`.
+By default, the local registry is stored at `~/.praison/registry`.

+# MCP Server Examples
+
+Examples demonstrating the MCP Server v2 features per MCP Protocol Version 2025-11-25.
+
+## Features Demonstrated
+
+### 1. Pagination (`pagination_example.py`)
+
+Demonstrates pagination for `tools/list`, `resources/list`, and `prompts/list`:
+
+- Opaque cursor encoding (base64url)
+- Server-determined page size (default: 50, max: 100)
+- `nextCursor` for fetching more results
+- Cursor validation with JSON-RPC errors
+
+```bash
+python pagination_example.py
+```
+
+### 2. Tool Annotations (`tool_annotations_example.py`)
+
+Demonstrates MCP 2025-11-25 tool annotation hints:
+
+- `readOnlyHint`: Tool only reads data
+- `destructiveHint`: Tool may have destructive effects
+- `idempotentHint`: Safe to call multiple times
+- `openWorldHint`: Interacts with external world
+
+```bash
+python tool_annotations_example.py
+```
+
+### 3. CLI Tools (`cli_tools_example.sh`)
+
+Demonstrates the new CLI commands:
+
+```bash
+# List tools with pagination
+praisonai mcp list-tools --limit 10
+praisonai mcp list-tools --cursor <cursor> --json
+
+# Search tools
+praisonai mcp tools search "query"
+praisonai mcp tools search --category memory
+praisonai mcp tools search --read-only
+praisonai mcp tools search --json
+
+# Get tool info
+praisonai mcp tools info <tool-name>
+praisonai mcp tools info <tool-name> --json
+
+# Get tool schema
+praisonai mcp tools schema <tool-name>
+```
+
+## API Reference
+
+### Pagination
+
+```python
+from praisonai.mcp_server.registry import MCPToolRegistry
+
+registry = MCPToolRegistry()
+# ... register tools ...
+
+# Get first page
+tools, next_cursor = registry.list_paginated(page_size=50)
+
+# Get next page
+if next_cursor:
+    more_tools, next_cursor = registry.list_paginated(cursor=next_cursor)
+```
+
+### Tool Search
+
+```python
+# Search by query
+tools, next_cursor, total = registry.search(query="memory")
+
+# Filter by category
+tools, _, _ = registry.search(category="file")
+
+# Filter by read-only hint
+tools, _, _ = registry.search(read_only=True)
+
+# Combined filters with pagination
+tools, next_cursor, total = registry.search(
+    query="data",
+    category="storage",
+    read_only=True,
+    page_size=10,
+)
+```
+
+### Tool Annotations
+
+```python
+from praisonai.mcp_server.registry import MCPToolDefinition
+
+# Read-only tool
+tool = MCPToolDefinition(
+    name="data.read",
+    description="Read data",
+    handler=read_handler,
+    input_schema={"type": "object"},
+    read_only_hint=True,
+    destructive_hint=False,
+)
+
+# Destructive tool
+tool = MCPToolDefinition(
+    name="file.delete",
+    description="Delete file",
+    handler=delete_handler,
+    input_schema={"type": "object"},
+    destructive_hint=True,
+    idempotent_hint=False,
+)
+```
+
+## MCP Protocol Compliance
+
+These examples comply with MCP Protocol Version 2025-11-25:
+
+- Pagination uses opaque cursors (base64url encoded)
+- Server determines page size (client cannot override)
+- Invalid cursors return JSON-RPC error code -32602
+- Tool annotations follow the spec defaults:
+  - `readOnlyHint`: false
+  - `destructiveHint`: true
+  - `idempotentHint`: false
+  - `openWorldHint`: true

+# Recipe Background Tasks Example
+
+This example demonstrates how to run recipes and agents as background tasks.
+
+## Prerequisites
+
+```bash
+pip install praisonai praisonaiagents
+export OPENAI_API_KEY="your-api-key"
+```
+
+## Python Example
+
+```bash
+python example_background.py
+```
+
+## CLI Examples
+
+### Submit a recipe as background task
+
+```bash
+# Submit recipe to background
+praisonai background submit --recipe my-recipe --input '{"query": "test"}'
+
+# Check status
+praisonai background status <task_id>
+
+# List all tasks
+praisonai background list
+
+# Cancel a task
+praisonai background cancel <task_id>
+
+# Clear completed tasks
+praisonai background clear
+```
+
+### Run recipe with --background flag
+
+```bash
+# Run recipe in background
+praisonai recipe run my-recipe --background
+
+# With input
+praisonai recipe run my-recipe --background --input '{"topic": "AI"}'
+
+# With session ID
+praisonai recipe run my-recipe --background --session-id session_123
+```
+
+## Key Features
+
+- **Async Execution**: Tasks run in the background without blocking
+- **Progress Tracking**: Monitor task progress and status
+- **Cancellation**: Cancel running tasks when needed
+- **Result Retrieval**: Get results when tasks complete
+- **Concurrency Control**: Limit concurrent tasks
+
+## Safe Defaults
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `timeout_sec` | 300 | Maximum execution time |
+| `max_concurrent` | 5 | Maximum concurrent tasks |

+# Recipe Scheduler Example
+
+This example demonstrates how to schedule recipes and agents to run periodically.
+
+## Prerequisites
+
+```bash
+pip install praisonai praisonaiagents
+export OPENAI_API_KEY="your-api-key"
+```
+
+## Python Example
+
+```bash
+python example_scheduler.py
+```
+
+Press Ctrl+C to stop the scheduler and see statistics.
+
+## CLI Examples
+
+### Start a scheduler with task
+
+```bash
+# Basic scheduler
+praisonai schedule start news-checker "Check AI news" --interval hourly
+
+# With timeout and budget
+praisonai schedule start reporter "Generate report" \
+    --interval daily \
+    --timeout 300 \
+    --max-cost 1.00
+
+# With max retries
+praisonai schedule start checker "Check updates" \
+    --interval hourly \
+    --max-retries 5
+```
+
+### Start a scheduler with recipe
+
+```bash
+# Schedule a recipe
+praisonai schedule start news-monitor --recipe news-analyzer --interval hourly
+
+# With all options
+praisonai schedule start my-scheduler \
+    --recipe my-recipe \
+    --interval "*/6h" \
+    --timeout 600 \
+    --max-cost 2.00 \
+    --max-retries 3
+```
+
+### Foreground mode (for testing)
+
+```bash
+# Run in foreground (Ctrl+C to stop)
+praisonai schedule "Check news" --interval "*/30s"
+```
+
+### Manage schedulers
+
+```bash
+# List all schedulers
+praisonai schedule list
+
+# View logs
+praisonai schedule logs news-checker --follow
+
+# Show statistics
+praisonai schedule stats news-checker
+
+# Stop a scheduler
+praisonai schedule stop news-checker
+
+# Stop all schedulers
+praisonai schedule stop-all
+
+# Delete a scheduler
+praisonai schedule delete news-checker
+```
+
+### Export scheduler config
+
+```bash
+praisonai schedule save news-checker --output news-checker.yaml
+```
+
+## Interval Formats
+
+| Format | Description |
+|--------|-------------|
+| `hourly` | Every hour |
+| `daily` | Every day |
+| `*/30m` | Every 30 minutes |
+| `*/6h` | Every 6 hours |
+| `*/30s` | Every 30 seconds (for testing) |
+| `3600` | Every 3600 seconds |
+
+## Key Features
+
+- **Periodic Execution**: Run tasks at regular intervals
+- **Retry Logic**: Automatic retries on failure
+- **Cost Budgeting**: Set spending limits
+- **Daemon Mode**: Run in background
+- **Statistics**: Track success rates
+
+## Safe Defaults
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `interval` | hourly | Execution interval |
+| `max_retries` | 3 | Retry attempts |
+| `timeout` | 300 | Timeout per execution |
+| `max_cost` | 1.00 | Budget limit (USD) |

+Package CLI Feature Handler
+
+Provides pip-like CLI commands for package management:
+- install: Install Python packages
+- uninstall: Uninstall Python packages
+- list: List installed packages
+- search: Search packages
+- index: Manage package indexes
+
+All commands use the canonical `praisonai` or `praisonai package` prefix.
+
+Security:
+- Default to single authoritative index (PyPI)
+- Warn loudly about dependency confusion when using extra indexes
+- Require explicit opt-in for extra index fallback

+
+Commands:
+  install     Install Python packages (shortcut: praisonai install)
+  uninstall   Uninstall Python packages (shortcut: praisonai uninstall)
+  list        List installed packages
+  search      Search for packages
+  index       Manage package indexes
+
+Examples:
+  praisonai install requests
+  praisonai install "requests>=2.28" httpx
+  praisonai uninstall requests
+  praisonai package list
+  praisonai package search langchain
+  praisonai package index show
+  praisonai package index set https://my-index.example.com/simple
+
+Options for 'install':
+  --index-url URL       Use custom index URL
+  --extra-index-url URL Add extra index (requires --allow-extra-index)
+  --allow-extra-index   Allow extra index URLs (security risk!)
+  --python PATH         Python interpreter to use
+  --upgrade, -U         Upgrade packages
+  --no-deps             Don't install dependencies
+  --json                Output in JSON format
+
+Options for 'uninstall':

+  --yes, -y             Don't ask for confirmation
+  --json                Output in JSON format
+
+Security Notes:
+  - By default, only the primary index is used (PyPI)
+  - Using --extra-index-url can lead to dependency confusion attacks
