What is the Deterministic Text Summarizer & Extractor MCP Server?
Large Language Models generate 'Abstractive' summaries (they write new text based on their understanding), which consumes a massive amount of tokens and can introduce hallucinations or skip crucial facts. The Text Summarizer & Extractor MCP solves this by using 'Extractive' summarization—a purely mathematical algorithm (Term Frequency) that pulls the exact, unmodified, most important sentences directly from the source text. It is the ultimate pre-processing tool for strict data extraction.
The Superpowers
- Extractive Summarization: Ranks all sentences in a document mathematically by keyword density and extracts the top N sentences. Zero hallucination.
- Keyword Extraction: Instantly counts term frequency (TF) to find the most repeated topics, completely ignoring grammatical stop words (English, Portuguese, Spanish).
- Bigram Analysis: Finds the most common two-word phrases, perfect for SEO topic modeling and strict semantic analysis.
- Zero-Dependency Architecture: Pure Javascript runtime execution guarantees absolute speed without bloated NLP packages.

Frequently asked questions
What is the difference between Extractive and Abstractive summarization?
Abstractive summarization (what ChatGPT does) writes a completely new text based on its understanding. Extractive summarization (what this tool does) selects the most mathematically important sentences directly from the original text without changing a single word. It guarantees 100% factual accuracy.
Does the keyword extraction ignore simple connection words?
Yes. It has a built-in cross-language 'Stop Words' dictionary (supporting English, Portuguese, and Spanish) to ensure words like 'the', 'and', 'for', 'uma' are completely ignored during Term Frequency calculations.
Why use this tool instead of just asking an AI to summarize?
If you have a massive 50-page document, passing the entire text into an AI context window is extremely expensive and slow. Running an algorithmic extraction first condenses the text dramatically while retaining all key facts.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Deterministic Text Summarizer & Extractor tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
