About obsidian-mcp-server
cyanheads/obsidian-mcp-server
Obsidian Knowledge-Management MCP (Model Context Protocol) server that enables AI agents and development tools to interact with an Obsidian vault. It provides a comprehensive suite of tools for reading, writing, searching, and managing notes, tags, and frontmatter, acting as a bridge to the Obsidian Local REST API plugin.
Implements a modular TypeScript architecture leveraging stdio transport for MCP communication with automatic reconnection, backed by an intelligent in-memory vault cache that provides fallback search functionality if the REST API becomes unavailable. Supports flexible file targeting (by path, active note, or periodic notes) and atomic frontmatter operations, with structured logging, Zod validation, and optional HTTP transport via Hono for alternative deployment scenarios.
About vaultforge
blacksmithers/vaultforge
Local MCP server for Obsidian vault operations — search, intelligence, canvas tools
Implements 27 tools including BM25-ranked full-text search (via Orama), canvas creation with automatic graph layout (dagre), and TF-IDF-based vault theme mapping—all optimized to minimize token consumption by returning semantically dense, ranked results rather than raw dumps. Runs as a stdio-based MCP server with no plugin dependency, designed specifically for AI agent workflows rather than direct human use. Handles batch operations, regex find-and-replace, backlink analysis, and canvas patching with semantic positioning instead of pixel coordinates.
