octave-mcp vs semble
octave-mcp: OCTAVE is a structured document format with an MCP server and CLI. It normalizes documents to a single canonical form, validates them against their own schema, and logs every transformation. It is designed for AI documents that need to survive compression, multi-agent handoffs, and auditing.; semble: Semble is a high-performance code search library designed for AI agents, providing instant access to precise code snippets. It offers significantly faster indexing and querying compared to transformer models, achieving 99% of their retrieval quality while running entirely on CPU without external dependencies.
01
TL;DR
Choose octave-mcp if…Documents passing through multiple agents, tools, or compression steps
Choose semble if…Enhancing AI agents (e.g., Claude Code, Cursor, Codex) with fast and accurate code search capabilities
