+# Connecting Serena MCP Server to ChatGPT via MCPO & Cloudflare Tunnel
+
+This guide explains how to expose a **locally running Serena MCP server** (powered by MCPO) to the internet using **Cloudflare Tunnel**, and how to connect it to **ChatGPT as a Custom GPT with tool access**.
+
+Once configured, ChatGPT becomes a powerful **coding agent** with direct access to your codebase, shell, and file system — so **read the security notes carefully**.
+
+---
+## Prerequisites
+
+Make sure you have [uv](https://docs.astral.sh/uv/getting-started/installation/) 
+and [cloudflared](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/) installed.
+
+## 1. Start the Serena MCP Server via MCPO
+
+Run the following command to launch Serena as http server (assuming port 8000):
+
+```bash
+uvx mcpo --port 8000 --api-key <YOUR_SECRET_KEY> -- \
+  uvx --from git+https://github.com/oraios/serena \
+  serena start-mcp-server --project $(pwd)
+```
+
+- `--api-key` is required to secure the server.
+- `--project` should point to the root of your codebase.
+
+You can also use other options, and you don't have to pass `--project` if you want to work on multiple projects
+or want to activate it later. See 
+
+```shell
+uvx --from git+https://github.com/oraios/serena serena start-mcp-server --help
+```
+
+---
+
+## 2. Expose the Server Using Cloudflare Tunnel
+
+Run:
+
+```bash
+cloudflared tunnel --url http://localhost:8000
+```
+
+This will give you a **public HTTPS URL** like:
+
+```
+https://serena-agent-tunnel.trycloudflare.com
+```
+
+Your server is now securely exposed to the internet.
+
+---
+
+## 3. Connect It to ChatGPT (Custom GPT)
+
+### Steps:
+
+1. Go to [ChatGPT → Explore GPTs → Create](https://chat.openai.com/gpts/editor)
+2. During setup, click **“Add APIs”**
+3. Set up **API Key authentication** with the auth type as **Bearer** and enter the api key you used to start the MCPO server.
+4. In the **Schema** section, click on **import from URL** and paste `<cloudflared_url>/openapi.json` with the URL you got from the previous step.
+5. Add the following line to the top of the imported JSON schema:
+    ```
+     "servers": ["url": "<cloudflared_url>"],
+    ```
+
+ChatGPT will read the schema and create functions automatically.
+
+---
+
+## Security Warning — Read Carefully
+
+Depending on your configuration and enabled tools, Serena's MCP server may:
+- Execute **arbitrary shell commands**
+- Read, write, and modify **files in your codebase**
+
+This gives ChatGPT the same powers as a remote developer on your machine.
+
+### ⚠️ Key Rules:
+- **NEVER expose your API key**
+- **Only expose this server when needed**, and monitor its use.
+
+In your project’s `.serena/project.yml` or global config, you can disable tools like:
+
+```yaml
+excluded_tools:
+  - execute_shell_command
+  - ...
+read_only: true
+```
+
+This is strongly recommended if you want a read-only or safer agent.
+
+
+---
+
+## Final Thoughts
+
+With this setup, ChatGPT becomes a coding assistant **running on your local code** — able to index, search, edit, and even run shell commands depending on your configuration.
+
+Use responsibly, and keep security in mind.
