+# 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

+# 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
