+# 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

+```
+
+### 2. HTTP Stream Server (http_stream_server.py)
+
+Run PraisonAI as an MCP server using HTTP Stream transport.
+
+```bash
+# Run directly
+python http_stream_server.py
+
+# Or via CLI
+praisonai mcp serve --transport http-stream --port 8080
+```
+
+### 3. Custom Tools Server (custom_tools_server.py)
+
+Register custom tools and expose them via MCP.
+
+```bash
+python custom_tools_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

+# Policy Packs Example
+
+This example demonstrates how to use PraisonAI policy packs for managing tool permissions, data policies, and execution modes.
+
+## Features Demonstrated
+
+- Creating and loading policy packs
+- Tool permission checking (allow/deny)
+- Policy modes (dev/prod)
+- Merging policies
+- Data and PII policies
+
+## Quick Start
+
+```bash
+python policy_example.py
+```
+
+## CLI Commands
+
+```bash
+# Show default policy
+praisonai recipe policy show
+
+# Show policy from file
+praisonai recipe policy show my-policy.yaml
+
+# Create policy template
+praisonai recipe policy init -o my-policy.yaml
+
+# Validate policy file
+praisonai recipe policy validate my-policy.yaml
+```
+
+## Policy File Format
+
+```yaml
+name: my-org-policy
+version: "1.0"
+
+tools:
+  allow:
+    - web.search
+    - db.query
+  deny:
+    - shell.exec
+    - file.write
+
+network:
+  allow_domains:
+    - api.openai.com
+  deny_domains:
+    - localhost
+
+pii:
+  mode: redact  # allow, deny, redact
+  fields:
+    - email
+    - phone
+
+data:
+  retention_days: 30
+  export_allowed: true
+
+modes:
+  dev:
+    allow_interactive_prompts: true
+    strict_tool_enforcement: false
+  prod:
+    allow_interactive_prompts: false
+    strict_tool_enforcement: true
+    require_auth: true
+```
+
+## Using Policy with Recipe Run
+
+```bash
+# Run with policy file
+praisonai recipe run my-recipe --policy my-policy.yaml --mode prod
+```

+Isolated Registry Example - Multi-Agent Safety
+
+This example demonstrates how to use isolated registries to prevent
+provider registration collisions in multi-agent scenarios.
+
+Key concepts:
+- Each agent/context can have its own registry
+- No global state mutation
+- Safe for concurrent/parallel runs
+- Different agents can use different provider implementations
+
+Requirements:
+- pip install praisonai

+# Recipe Registry Example
+
+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
+- Starting an HTTP registry server
+- Publishing recipes with token authentication
+- Listing and searching recipes
+- Pulling recipes from HTTP registry
+
+## Quick Start
+
+```bash
+# Run the HTTP registry example
+python http_registry_example.py
+```
+
+## HTTP Registry Server
+
+```bash
+# 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 from local registry
+praisonai recipe pull [email protected] -o ./recipes
+
+# Use custom local path
+praisonai recipe publish ./my-recipe --registry /path/to/registry
+```
+
+## Environment Variables
+
+- `PRAISONAI_REGISTRY_TOKEN` - Default token for HTTP registry authentication
+
+## Default Registry Location
+
+By default, the local registry is stored at `~/.praison/registry`.

+# Run History Example
+
+This example demonstrates how to use PraisonAI run history for storing, querying, and exporting recipe runs.
+
+## Features Demonstrated
+
+- Storing run results with input/output data
+- Listing and filtering runs
+- Querying run details
+- Exporting runs for replay/debugging
+- Storage statistics and cleanup
+
+## Quick Start
+
+```bash
+python run_history_example.py
+```
+
+## CLI Commands
+
+```bash
+# List recent runs
+praisonai recipe runs list
+
+# List runs for a specific recipe
+praisonai recipe runs list --recipe support-reply
+
+# Get storage stats
+praisonai recipe runs stats
+
+# Export a run
+praisonai recipe export run-abc123 -o export.json
+
+# Replay a run
+praisonai recipe replay export.json --compare
+
+# Cleanup old runs
+praisonai recipe runs cleanup
+```
+
+## Default Storage Location
+
+Run history is stored at `~/.praison/runs`.
