openchronicle-mcp vs markdown-vault-mcp
openchronicle-mcp: OpenChronicle is a memory database designed for LLM agents, offering persistent semantic and keyword memory, project namespacing, and Git integration. It provides hybrid search capabilities and is served over HTTP REST and MCP from a single ASGI process, deployable on your hardware.; markdown-vault-mcp: This tool is a generic Model Context Protocol (MCP) server designed for managing markdown collections, featuring full-text and semantic search capabilities. It allows users to point it at a directory of markdown files and exposes search, read, write, and edit tools over the MCP, supporting various vault types like Obsidian or Zettelkasten.

Features
openchronicle-mcp01Persistent memory across sessions with hybrid full-text and semantic search (RRF).
02Project namespacing to scope memory contexts and prevent leakage between workstreams.
03Git integration for onboarding existing codebases by clustering and summarizing commits.
04Single ASGI process serving both HTTP REST API and MCP streamable-HTTP transport.
05Robust data management with atomic online backups and a schema migration framework.
markdown-vault-mcp01Full-text and Semantic Search: Combines SQLite FTS5 with BM25 scoring and semantic vector search using embeddings (FastEmbed, Ollama, OpenAI), including hybrid search with Reciprocal Rank Fusion.
02Adaptive Heading-Level Chunking: Recursively splits long sections at deeper heading levels until each chunk fits a configurable word budget, enhancing retrieval precision for LLMs.
03Comprehensive Vault Management: Provides frontmatter-aware indexing, incremental reindexing, write operations (create, edit, delete, rename), and support for non-markdown attachments.
04LLM-Visible Tools and Resources: Offers over 30 LLM-visible tools for vault interaction (search, read, write, admin) and 9 resources for accessing vault metadata (config, stats, tags).
05Git Integration and OIDC Authentication: Features optional auto-commit and push on writes via Git integration, alongside robust OIDC authentication for secure HTTP deployments.
