# Sandbox Testing Walk-Through

### MCP Observability

1. Login to your BlueRock Sandbox instance
2. Gemini is preloaded on the instance as an example.  Run the gemini CLI command::\
   \
   `gemini`

   \
   You may need to start the MCP servers first:

   \
   `cd /opt/bluerock/trex/servicenow-mcp`

   `source .venv/bin/activate`\
   `servicenow-mcp-sse --host=127.0.0.1 --port=8001 &`<br>
3. Open a second terminal session.\
   \
   `cd /opt/bluerock/trex/fastmcp`\
   `source .venv/bin/activate`\
   `python my_server.py &`<br>
4. Run `/mcp` in the gemini CLI to view all available tools

6. Execute the mongo\_list\_databases tool for FastMCP:\ <br>

8. Select your **Log stream**:\ <br>

9. Search for **python\_mcp** in the search bar. This will list out all of the MCP calls and connections:\ <br>

   <figure><img src="https://984714674-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FCj4nQ903CxyVJLmoOyKU%2Fuploads%2Fh8LiVx0K8tdv8P0WRNwA%2Funknown.png?alt=media&#x26;token=93687b83-8d96-4859-9940-8d5558f93147" alt=""><figcaption></figcaption></figure>

10. Now search for **{ $.body.message.method = "initialize" }**. This is the initial connection and MCP handshake between the client and server:\ <br>

11. Next let’s list all of the tools by searching for **{ $.body.message.result.tools\[0].name = "list\_tool\_packages" }**:\ <br>

    <figure><img src="https://984714674-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FCj4nQ903CxyVJLmoOyKU%2Fuploads%2FLou0iEqAkLxks7zHEz7I%2Funknown.png?alt=media&#x26;token=f950ffc4-6729-450b-bfae-7325b3030186" alt=""><figcaption></figcaption></figure>

12. Next search **“tools/call”**. Make sure to use the quotes in the search. This will now show the specific tool calls used by the MCP Client:\ <br>
