Model Description

Fine-tuned for MCP (Model Context Protocol) tool calling with the Claude Chrome extension. The model generates tool calls for browser automation tasks.

Training Details

• Base Model: google/functiongemma-270m-it
• Method: LoRA fine-tuning on Apple Silicon (MLX)
• Dataset: 1,782 MCP browser automation examples
• Validation Loss: 0.027
• Iterations: 500
• Naming Convention: {base}-{size}-ccmcp-{version}
  • ccmcp = Claude Chrome MCP

Usage

With MLX (Apple Silicon)

from mlx_lm import load, generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load(
    "mlx-community/functiongemma-270m-it-4bit",
    adapter_path="pierretokns/functiongemma-270m-ccmcp-v1"
)

messages = [
    {"role": "system", "content": "You are a browser automation assistant with MCP tools."},
    {"role": "user", "content": "Go to google.com"}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
sampler = make_sampler(temp=0.1)

response = generate(model, tokenizer, prompt=prompt, max_tokens=150, sampler=sampler)
print(response)
