agent-brain

v10.7.0

by SpillwaveSolutions · author: Spillwave Solutions

Local-first RAG memory for AI agents: hybrid BM25/semantic search, GraphRAG, and an MCP server with OAuth 2.1. Index docs and code, then search from Claude Code, Cursor, Codex, OpenCode, or Grok Build.

What agent-brain does, in the publisher's words

A multi-host plugin for document search with hybrid BM25/semantic retrieval. Index your documentation and source code, then search using keyword matching, semantic similarity, or combined hybrid mode. Installs natively in Claude Code, OpenCode, Codex, Cursor, and Grok Build; a conforming Agent Plugins 1.0 client can consume plugin.json + skills/ + mcp.json.

  • Hybrid Search: Combines BM25 keyword matching with semantic vector search for best results
  • Three Search Modes: BM25 (fast keywords), Vector (semantic), Hybrid (combined)
  • Multi-Instance: Run separate servers for different projects with automatic port allocation
  • Code Search: AST-aware indexing for Python, TypeScript, JavaScript, Java, Go, Rust, C, C++
