Example 1: Generate a Simple Distance CV with Metadynamics

Prompt to AI:

Generate a PLUMED input file for metadynamics simulation of a protein. I want to use the distance between atoms 1 and 2 as a collective variable, with metadynamics bias. Include output every 100 steps.

Expected AI Response: The AI will use the generate_plumed_input tool with parameters like:

{
  "collective_variables": [
    {
      "type": "DISTANCE",
      "label": "d1",
      "atoms": [1, 2]
    }
  ],
  "bias_methods": [
    {
      "type": "METAD",
      "arg": "d1",
      "sigma": 0.1,
      "height": 1.0,
      "pace": 500
    }
  ],
  "output_config": {
    "stride": 100,
    "file": "colvar.dat"
  }
}

Generated Output:

# PLUMED input file generated by PLUMED2 MCP Server
# Collective Variables
d1: DISTANCE ATOMS=1,2

# Bias Methods  
METAD ARG=d1 SIGMA=0.1 HEIGHT=1.0 PACE=500

# Output
PRINT ARG=d1 STRIDE=100 FILE=colvar.dat

Example 2: Validate PLUMED Syntax

Prompt to AI:

Please validate this PLUMED input:
d: DISTANCE ATOMS=1,2
METAD ARG=d SIGMA=0.1 HEIGHT=1.0 PACE=500
PRINT ARG=d STRIDE=100 FILE=colvar.dat

Expected AI Response: The AI will use the validate_plumed_syntax tool and report validation results, including any syntax errors, warnings, or suggestions.

Example 3: Get Performance Optimization

Prompt to AI:

Optimize this PLUMED input for a large system with 100,000 atoms:
[PLUMED input content]

Expected AI Response: The AI will use the optimize_plumed_performance tool and provide specific suggestions like using neighbor lists, adjusting stride values, or optimizing collective variable calculations.

Example 4: Use Templates

Prompt to AI:

Give me a PLUMED template for protein folding studies.

Expected AI Response: The AI will use the get_plumed_template tool with template_name: "protein_folding" and return a complete template with common collective variables and bias methods for protein folding simulations.
