Overview

AI-generated overview

Compresses numerical data series into short natural-language summaries so an assistant can reason about trends, volatility and anomalies without raw data.

What you can do
  • Analyze a single numerical series and return a short narrative with trend, volatility, anomalies, seasonality, distribution, step changes and data quality
  • Analyze several series or all numeric columns of a DataFrame in one call
  • Return structured JSON output instead of prose for downstream use
  • Run trading-oriented analyses: drawdown, performance metrics, rankings, windows, market regime and allocation suggestions
When to use it
Useful when an assistant needs to interpret large numeric datasets, such as metrics, sensor readings, sales figures or price series, while keeping the context window small and avoiding arithmetic guesswork. Also relevant for agent workflows that need deterministic statistics summarized in text.
Requirements
Runs locally as a Python package installed with pip or uv, with the mcp extra for the server. No accounts, API keys or environment variables are declared. The README shows launching it through uvx or mcp run.
Before you install
The allocation tool produces portfolio suggestions that the README marks as educational only, not financial advice. Analysis is computed locally from data you pass in; the README does not describe sending data elsewhere, but the summaries are meant to be placed in prompts sent to a model provider.

Installation

In SourceWeft

  1. Open Semantic Frame in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Semantic Frame

[MCP Registry] [PyPI version] [License: MIT]

Token-efficient semantic compression for numerical data.

Semantic Frame converts 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, send a 50-word semantic summary.

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:

python
from semantic_frame import describe_seriesimport 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 stablevariability. 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

bash
pip install semantic-frame

Or with uv:

bash
uv add semantic-frame

🤖 Claude Integration (MCP)

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

Claude Code CLI:

bash
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

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
  • describe_batch - Analyze multiple series at once
  • describe_json - Get structured JSON output

Quick Start

Analyze a Series

python
from semantic_frame import describe_seriesimport numpy as np
# Works with NumPy arraysdata = 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

python
from semantic_frame import describe_dataframeimport 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

python
result = describe_series(data, output="full")
print(result.trend)          # TrendState.RISING_SHARPprint(result.volatility)     # VolatilityState.MODERATEprint(result.anomalies)      # [AnomalyInfo(index=4, value=500.0, z_score=4.2)]print(result.compression_ratio)  # 0.95

JSON Output for APIs

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

Supported Data Types

  • NumPy: np.ndarray
  • Pandas: pd.Series, pd.DataFrame
  • Polars: pl.Series, pl.DataFrame
