+# ACP (Agent Client Protocol) Examples
+
+This directory contains examples for using PraisonAI with the Agent Client Protocol (ACP).
+
+## What is ACP?
+
+The Agent Client Protocol (ACP) is a standardized JSON-RPC 2.0 protocol that allows code editors and IDEs to communicate with AI coding agents. It enables seamless integration between PraisonAI and editors like:
+
+- **Zed**
+- **JetBrains IDEs** (IntelliJ, PyCharm, WebStorm, etc.)
+- **VSCode** (via extensions)
+- **Toad**
+
+## Quick Start
+
+### CLI Usage
+
+```bash
+# Start ACP server with defaults
+praisonai acp
+
+# Enable debug logging
+praisonai acp --debug
+
+# Allow file writes
+praisonai acp --allow-write
+
+# Use a specific model
+praisonai acp -m gpt-4o
+
+# Resume last session
+praisonai acp --resume --last
+```
+
+### Python API
+
+```python
+from praisonai.acp import serve
+
+serve(
+    workspace=".",
+    debug=True,
+    allow_write=True,
+)
+```
+
+## Editor Configuration
+
+### Zed
+
+Add to `~/.config/zed/settings.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### JetBrains
+
+Add to `~/.jetbrains/acp.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### Toad
+
+```bash
+toad acp "praisonai acp"
+```
+
+## Examples
+
+- `basic_acp_server.py` - Simple ACP server with default settings
+- `custom_agent_acp.py` - ACP server with a custom agent
+
+## CLI Options
+
+| Option | Description |
+|--------|-------------|
+| `-w, --workspace` | Workspace root directory |
+| `-a, --agent` | Agent name or config file |
+| `-m, --model` | LLM model to use |
+| `-r, --resume` | Resume session by ID |
+| `--last` | Resume the last session |
+| `--approve` | Approval mode: manual, auto, scoped |
+| `--read-only` | Read-only mode (default) |
+| `--allow-write` | Allow file writes |
+| `--allow-shell` | Allow shell commands |
+| `--debug` | Enable debug logging |
+
+## Installation
+
+```bash
+pip install praisonai[acp]
+```
+
+## Protocol Details
+
+ACP uses JSON-RPC 2.0 over stdio:
+- **stdin**: Receives JSON-RPC requests from the client
+- **stdout**: Sends JSON-RPC responses to the client
+- **stderr**: Debug/log output (never pollutes stdout)
+
+### Supported Methods
+
+**Agent Methods (client → agent):**
+- `initialize` - Negotiate protocol version and capabilities
+- `authenticate` - Optional authentication
+- `session/new` - Create a new session
+- `session/load` - Load an existing session
+- `session/prompt` - Send user message
+- `session/cancel` - Cancel ongoing operations
+- `session/set_mode` - Change operating mode
+
+**Client Methods (agent → client):**
+- `session/update` - Send progress updates
+- `session/request_permission` - Request user approval
+- `fs/read_text_file` - Read file contents
+- `fs/write_text_file` - Write file contents
+- `terminal/create` - Create terminal
+- `terminal/output` - Get terminal output

+# 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
+
+# Or via CLI
+praisonai mcp serve --transport stdio
+```
+
+### 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

+# 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

+# 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`.

+# Security Features Example
+
+This example demonstrates PraisonAI security features including SBOM generation, lockfile validation, dependency auditing, and PII redaction.
+
+## Features Demonstrated
+
+- **SBOM Generation**: Generate Software Bill of Materials in CycloneDX or SPDX format
+- **Lockfile Validation**: Validate presence and format of dependency lockfiles
+- **Dependency Auditing**: Audit dependencies for vulnerabilities
+- **PII Redaction**: Detect and redact personally identifiable information
+
+## Quick Start
+
+```bash
+python security_example.py
+```
+
+## CLI Commands
+
+### SBOM Generation
+
+```bash
+# Generate CycloneDX SBOM
+praisonai recipe sbom ./my-recipe --format cyclonedx -o sbom.json
+
+# Generate SPDX SBOM
+praisonai recipe sbom ./my-recipe --format spdx -o sbom.json
+```
+
+### Dependency Auditing
+
+```bash
+# Audit dependencies
+praisonai recipe audit ./my-recipe
+
+# Strict audit (fail on issues)
+praisonai recipe audit ./my-recipe --strict
+```
+
+### Lockfile Validation
+
+```bash
+# Validate recipe (includes lockfile check)
+praisonai recipe validate ./my-recipe --require-lockfile
+```
+
+## PII Redaction Configuration
+
+In your `TEMPLATE.yaml`:
+
+```yaml
+data_policy:
+  pii:
+    mode: redact  # allow, deny, or redact
+    fields:
+      - email
+      - phone
+      - ssn
+      - credit_card
