What is the TF-IDF Vectorizer Engine MCP Server?
Large Language Models often hallucinate when asked to perform statistical text analysis like TF-IDF (Term Frequency-Inverse Document Frequency). They simply guess which keywords seem 'important'. This engine calculates mathematically perfect TF-IDF scores across arrays of documents deterministically local, using the Node.js V8 engine. It allows agents to rank documents objectively by true term relevance.
Built-in capabilities (1)
Calculates the exact TF-IDF scores for an array of terms across an array of documents

Frequently asked questions
Why is TF-IDF better than simple word counting?
Word counting overvalues common words like 'the' or 'and'. TF-IDF lowers the weight of words that appear in many documents, highlighting terms that are uniquely relevant to a specific text.
Can it process JSON document arrays?
Yes, just provide a stringified JSON array of text documents and a target array of terms. The engine handles the corpus building and tokenization.
Does it work in languages other than English?
Yes, TF-IDF relies on token frequency, making it highly effective for multi-language corpuses without needing specific translation logic.
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 TF-IDF Vectorizer Engine 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.
