Matryoshka

Overview

Matryoshka is an innovative MCP server that enables analysis of documents up to 100x larger than a language model's context window. Instead of traditional RAG or chunking approaches, it uses a Recursive Language Model (RLM) approach where the LLM outputs symbolic commands in a specialized Nucleus DSL that are executed by a logic engine. This architecture reduces token usage by 97%+ and maintains document-wide context without vector databases. The server provides two MCP interfaces: one with full LLM orchestration and another exposing direct Nucleus commands for programmatic access.

FAQ

How does Matryoshka handle documents larger than context window?

It uses a recursive language model approach where the LLM outputs symbolic commands that are executed by a logic engine against the full document, eliminating the need for chunking.

What is the Nucleus DSL?

Nucleus is a constrained symbolic language based on S-expressions designed specifically for document analysis. It provides commands like grep, filter, and sum that the LLM can output to manipulate document data.
