-# MCP client usage
-
-Agentic Security exposes an MCP stdio server in `agentic_security.mcp.main`.
-The example client in `examples/mcp_client_usage.py` shows how to connect to
-that server, list available tools, and optionally call simple no-argument tools.
-
-## List MCP tools
-
-From the repository root:
-
-```shell
-python examples/mcp_client_usage.py
-```
-
-This starts the MCP server as a subprocess with:
-
-```shell
-python -m agentic_security.mcp.main
-```
-
-The client initializes an MCP session and prints the available Agentic Security
-tools, including `verify_llm`, `start_scan`, `stop_scan`, `get_data_config`, and
-`get_spec_templates`.
-
-## Call an HTTP-backed tool
-
-Some MCP tools call the Agentic Security HTTP app. Start the app in another
-terminal first:
-
-```shell
-agentic_security --host 127.0.0.1 --port 8718
-```
-
-Then point the MCP server at that app and call a no-argument tool:
-
-```shell
-python examples/mcp_client_usage.py \
-  --agentic-security-url http://127.0.0.1:8718 \
-  --call get_spec_templates
-```
-
-You can also set `AGENTIC_SECURITY_URL` directly:
-
-```shell
-AGENTIC_SECURITY_URL=http://127.0.0.1:8718 python examples/mcp_client_usage.py --call get_data_config
-```
-
-## Use the package helper
-
-For tests or quick local checks, `agentic_security.mcp.client.run()` creates the
-same stdio session and returns the prompt, resource, and tool list results:
-
-```python
-import asyncio
-
-from agentic_security.mcp.client import run
-
-
-async def main() -> None:
-    _prompts, _resources, tools = await run()
-    print([tool.name for tool in tools.tools])
-
-
-asyncio.run(main())
-```
