Semantic Frame

🚀 Semantic Frame

Token-efficient semantic compression for numerical data.

Semantic Frame transforms raw numerical data (NumPy, Pandas, Polars) into natural language descriptions optimized for LLM consumption. Instead of sending thousands of data points to an AI agent, you can send a 50-word semantic summary.

🚀 Quick Start

Analyze a Series

from semantic_frame import describe_series
import numpy as np

# Works with NumPy arrays
data = np.array([10, 20, 30, 40, 50, 60, 70, 80, 90, 100])
result = describe_series(data, context="Daily Sales")
print(result)
# "The Daily Sales data shows a rapidly rising pattern with moderate variability..."

Analyze a DataFrame

from semantic_frame import describe_dataframe
import pandas as pd

df = pd.DataFrame({
    'cpu': [40, 42, 41, 95, 40, 41],
    'memory': [60, 61, 60, 60, 61, 60],
})

results = describe_dataframe(df, context="Server Metrics")
print(results['cpu'].narrative)
# "The Server Metrics - cpu data shows a flat/stationary pattern..."

Get Structured Output

result = describe_series(data, output="full")

print(result.trend)          # TrendState.RISING_SHARP
print(result.volatility)     # VolatilityState.MODERATE
print(result.anomalies)      # [AnomalyInfo(index=4, value=500.0, z_score=4.2)]
print(result.compression_ratio)  # 0.95

JSON Output for APIs

result = describe_series(data, output="json")
# Returns dict ready for JSON serialization

✨ Features

The Problem

LLMs are terrible at arithmetic. When you send raw data like [100, 102, 99, 101, 500, 100, 98] to GPT - 4 or Claude:

• Token waste: 1000 data points = ~2000 tokens
• Hallucination risk: LLMs guess trends instead of calculating them
• Context overflow: Large datasets fill the context window

The Solution

Semantic Frame provides deterministic analysis using NumPy, then translates results into token - efficient narratives:

from semantic_frame import describe_series
import pandas as pd

data = pd.Series([100, 102, 99, 101, 500, 100, 98])
print(describe_series(data, context="Server Latency (ms)"))

Output:

The Server Latency (ms) data shows a flat/stationary pattern with stable
variability. 1 anomaly detected at index 4 (value: 500.00).
Baseline: 100.00 (range: 98.00-500.00).

Result: 95%+ token reduction, zero hallucination risk.

📦 Installation

pip install semantic-frame

Or with uv:

uv add semantic-frame

🤖 Claude Integration (MCP)

Semantic Frame is available on the official MCP Registry, enabling direct integration with Claude.

Claude Code CLI:

claude mcp add semantic-frame

Claude Desktop - Add to your claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "semantic-frame": {
      "command": "uvx",
      "args": ["--from", "semantic-frame[mcp]", "semantic-frame-mcp"]
    }
  }
}

Once configured, Claude can use these tools:

• describe_data - Analyze a single data series

Claude Code

Add Semantic Frame as a native tool in Claude Code:

# Install MCP dependencies
pip install semantic-frame[mcp]

# Add MCP server to Claude Code
claude mcp add semantic-frame -- uv run --project /path/to/semantic-frame mcp run /path/to/semantic-frame/semantic_frame/integrations/mcp.py
