Overview

AI-generated overview

RAGScore is a local MCP server that generates QA datasets from your documents and evaluates a RAG endpoint, scoring answers and diagnosing failures.

What you can do
Generate QA pairs from documents, optionally tailored to an audience and purpose, with question, answer, rationale and support span saved as JSONL. Evaluate a RAG endpoint against those golden QAs and get accuracy, average score and a list of incorrect pairs. Run detailed multi-metric scoring on correctness, completeness, relevance, conciseness and faithfulness. Diagnose failures as retriever miss, generator hallucination, incomplete answer or wrong interpretation. Use the Python API to get results as a DataFrame and plot charts.
When to use it
Useful when you maintain a RAG or question-answering service and want a repeatable way to build test questions from your own docs and measure answer quality. Also suited to diagnosing why answers fail, or to private evaluation of confidential documents with a local model.
Requirements
Runs locally as a Python package installed with pip; the MCP mode is started with the serve command. Needs an LLM: local Ollama (no key) or a cloud provider, with OPENAI_API_KEY or ANTHROPIC_API_KEY set for those providers. The RAG system under test must expose a query endpoint. Optional settings include RAGSCORE_CHUNK_SIZE, RAGSCORE_QUESTIONS_PER_CHUNK and RAGSCORE_WORK_DIR.
Before you install
Document text chunks are sent to the chosen LLM provider when a cloud model is used; only local Ollama keeps everything on the machine. Telemetry is collected in MCP server mode only and can be disabled with RAGSCORE_NO_TELEMETRY. Evaluation sends questions to the RAG endpoint you configure, so point it only at systems you are allowed to test. API keys are read from environment variables.

Installation

In SourceWeft

  1. Open RAGScore 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.

⚡ 2-Line RAG Evaluation

bash
# Step 1: Generate QA pairs from your docsragscore generate docs/
# Step 2: Evaluate your RAG systemragscore evaluate http://localhost:8000/query

That's it. Get accuracy scores and incorrect QA pairs instantly.

============================================================✅ EXCELLENT: 85/100 correct (85.0%)Average Score: 4.20/5.0============================================================
❌ 15 Incorrect Pairs:
  1. Q: "What is RAG?"     Score: 2/5 - Factually incorrect
  2. Q: "How does retrieval work?"     Score: 3/5 - Incomplete answer

🚀 Quick Start

Install

bash
pip install ragscore              # Core (works with Ollama)pip install "ragscore[openai]"    # + OpenAI supportpip install "ragscore[notebook]"  # + Jupyter/Colab supportpip install "ragscore[all]"       # + All providers

Already installed? Keep up to date — new versions add features like failure diagnosis and retrieved context capture:

bash
pip install --upgrade ragscore

Option 1: Python API (Notebook-Friendly)

Perfect for Jupyter, Colab, and rapid iteration. Get instant visualizations.

python
from ragscore import quick_test
# 1. Audit your RAG in one lineresult = quick_test(    endpoint="http://localhost:8000/query",  # Your RAG API    docs="docs/",                            # Your documents    n=10,                                    # Number of test questions)
# 1b. Tailored QA — target specific audiencesresult = quick_test(    endpoint="http://localhost:8000/query",    docs="docs/",    audience="developers",                   # Who asks the questions?    purpose="api-integration",               # What's the document for?)
# 2. See the reportresult.plot()
# 3. Inspect failuresbad_rows = result.df[result.df['score'] < 3]display(bad_rows[['question', 'rag_answer', 'reason']])

Rich Object API:

  • result.accuracy - Accuracy score
  • result.df - Pandas DataFrame of all results
  • result.plot() - 3-panel visualization (4-panel with detailed=True)
  • result.corrections - List of items to fix

Option 2: CLI (Production)

Generate QA Pairs

bash
# Set API key (or use local Ollama - no key needed!)export OPENAI_API_KEY="sk-..."
# Generate from any documentragscore generate paper.pdfragscore generate docs/*.pdf --concurrency 10
# Tailored QA generation — target specific audiencesragscore generate docs/ --audience developers --purpose faqragscore generate docs/ --audience customers --purpose "pre-sales"ragscore generate docs/ --audience "compliance auditors" --purpose "security audit"

Evaluate Your RAG

bash
# Point to your RAG endpointragscore evaluate http://localhost:8000/query
# Custom optionsragscore evaluate http://api/ask --model gpt-4o --output results.json

🔬 Detailed Multi-Metric Evaluation

Go beyond a single score. Add detailed=True to get 5 diagnostic dimensions per answer — in the same single LLM call.

python
result = quick_test(    endpoint=my_rag,    docs="docs/",    n=10,    detailed=True,  # ⭐ Enable multi-metric evaluation)
# Inspect per-question metricsdisplay(result.df[[    "question", "score", "correctness", "completeness",    "relevance", "conciseness", "faithfulness"]])
# Radar chart + 4-panel visualizationresult.plot()
==================================================✅ PASSED: 9/10 correct (90%)Average Score: 4.3/5.0Threshold: 70%──────────────────────────────────────────────────  Correctness: 4.5/5.0  Completeness: 4.2/5.0  Relevance: 4.8/5.0  Conciseness: 4.1/5.0  Faithfulness: 4.6/5.0==================================================
MetricWhat it measuresScale
CorrectnessSemantic match to golden answer5 = fully correct
CompletenessCovers all key points5 = fully covered
RelevanceAddresses the question asked5 = perfectly on-topic
ConcisenessFocused, no filler5 = concise and precise
FaithfulnessNo fabricated claims5 = fully faithful

CLI:

bash
ragscore evaluate http://localhost:8000/query --detailed

🔍 Failure Diagnosis (--diagnose)

When answers fail, --diagnose tells you why — retriever miss, generator hallucination, incomplete answer, or wrong interpretation:

bash
ragscore evaluate http://localhost:8000/query --diagnose
🔍 Failure Diagnosis:  Retriever Miss: 3 (42.9%)  Generator Hallucination: 2 (28.6%)  Incomplete Answer: 1 (14.3%)  Wrong Interpretation: 1 (14.3%)

Uses the support_span already generated with each QA pair to give the judge grounding context. Combine with --detailed for full diagnostics:

bash
ragscore evaluate http://localhost:8000/query --diagnose --detailed -o results.json
CategoryMeaning
Retriever MissRAG didn't retrieve the chunk containing the evidence
Generator HallucinationRetrieved correctly but fabricated information
Incomplete AnswerRetrieved correctly but answer is partial
Wrong InterpretationRetrieved correctly but misunderstood the content

Ollama Model Recommendations

RAGScore generates complex structured QA pairs (question + answer + rationale + support span) in JSON format. This requires models with strong instruction-following and JSON output capabilities.

llama3.1:70b40GB48GB VRAMExcellentGPU server (A100, L40)

qwen2.5:1.5b1.0GB2GB RAMPoorNot recommended

Minimum recommended: 8B+ models. Smaller models (1.5B–3B) produce lower quality support spans and may timeout on longer chunks.

Ollama Performance Guide

bash
# Recommended: 8B model with concurrency 2 for local machinesollama pull llama3.1:8bragscore generate docs/ --provider ollama --model llama3.1:8b
# GPU server (A10/L20): larger model with higher concurrencyollama pull qwen2.5:32bragscore generate docs/ --provider ollama --model qwen2.5:32b --concurrency 5

Expected performance (28 chunks, 5 QA pairs per chunk):

📡 Telemetry

RAGScore collects telemetry only in MCP server mode (ragscore serve). Standard CLI and Python API usage do not send telemetry.

We collect limited anonymous operational metrics to understand feature usage and improve reliability. No document content, prompts, QA text, model outputs, API keys, endpoint URLs, or file paths are collected.

Collected in MCP mode:

  • MCP tool invoked
  • LLM provider and model name
  • ragscore version, Python version, OS type
  • Success/failure status
  • Random anonymous installation ID

Opt out:

bash
export RAGSCORE_NO_TELEMETRY=1
