What is the N-Gram Frequency Engine MCP Server?
Counting the most frequent 2-word or 3-word phrases (N-Grams) in a 100-page document is an expensive and inaccurate task for an LLM. Due to token limits, LLMs will approximate the counts or miss phrases entirely. The N-Gram Frequency Engine processes the text directly in native V8 JavaScript, delivering mathematically perfect frequency counts for bigrams, trigrams, and custom N-Grams in milliseconds.
Built-in capabilities (1)
Extracts the top most frequent N-Grams (e.g. bigrams, trigrams) from a text deterministically

Why teams choose Vinkius for N-Gram Frequency Engine in LlamaIndex
The N-Gram Frequency Engine MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 1 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in LlamaIndex only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
N-Gram Frequency Engine for LlamaIndex
Every tool call from LlamaIndex to the N-Gram Frequency Engine MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
What are Bigrams and Trigrams?
A bigram is a sequence of two adjacent words (e.g., 'machine learning'). A trigram is three (e.g., 'natural language processing').
Does it lowercase the text automatically?
Yes, all text is automatically lowercased and tokenized natively to ensure accurate aggregation of phrases.
Is this faster than asking Claude?
Significantly faster and 100% accurate. LLMs cannot count occurrences across thousands of tokens reliably.
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 N-Gram Frequency 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.
