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 &

3. Open a second terminal session. cd /opt/bluerock/trex/fastmcp source .venv/bin/activate python my_server.py &

4. Run /mcp in the gemini CLI to view all available tools

The following tools will display:

1. Execute the list_users tool for servicenow:

   

1. Execute the mongo_list_databases tool for FastMCP:

   

1. Now let’s check the CloudWatch logs in AWS. Navigate to CloudWatch and select your Log group

   

1. Select your Log stream:

   

1. Search for python_mcp in the search bar. This will list out all of the MCP calls and connections:

   

1. Now search for { $.body.message.method = "initialize" }. This is the initial connection and MCP handshake between the client and server:

   

1. Next let’s list all of the tools by searching for { $.body.message.result.tools[0].name = "list_tool_packages" }:

   

1. 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:
