Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Token-efficient semantic compression for numerical data. 95%+ token reduction.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 11 months ago.

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.
LLMs are terrible at arithmetic. When you send raw data like [100, 102, 99, 101, 500, 100, 98] to GPT-4 or Claude:
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.
pip install semantic-frame
Or with uv:
uv add semantic-frame
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 seriesdescribe_batch - Analyze multiple series at oncedescribe_json - Get structured JSON outputfrom semantic_frame import describe_series
import numpy as np

from semantic_frame import describe_dataframe

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

pip install semantic-frame[mcp]
Run the MCP server:
mcp run semantic_frame.integrations.mcp:mcp
Exposes describe_data tool for MCP clients like:
Add Semantic Frame as a native tool in Claude Code:
# Install MCP dependencies
pip install semantic-frame[mcp]
claude mcp add semantic-frame -- uv run --project /path/to/semantic-frame mcp run /path/to/semantic-frame/semantic_frame/integrations/mcp.py
claude mcp list
Once configured, ask Claude to analyze data and it will use the describe_data tool automatically.
Semantic Frame supports Anthropic's Advanced Tool Use features for efficient tool orchestration in complex agent workflows.
