## Initialize and use

# Protocol text
protocol = """

2. Set up PCR master mix according to the table.
3. Pipette 20 µL of PCR master mix into appropriate PCR tubes.

# Convert to executable JSON

# Execute the JSON
result = await client.session.call_tool("execute_json", arguments={"executable_json": json.dumps(executable_json)})

Tools:

• generate_executable_json: Convert protocol text to executable JSON

  • Args: protocol (str) - Protocol text
  • Returns: JSON with executable steps

• execute_json: Execute JSON protocol

  • Args: executable_json (str) - JSON string
  • Returns: Execution log with step-by-step operations

Use Cases

• Lab automation, robotic liquid handling, protocol standardization, reproducibility
