About obsidian-mcp-server
smith-and-web/obsidian-mcp-server
MCP server for Obsidian vault management - enables Claude and other AI assistants to read, write, search, and organize your notes
Implements MCP over Server-Sent Events (SSE) transport for remote vault access without local installation, alongside stdio mode for direct integration. Provides granular operations including section-level editing, YAML frontmatter manipulation, regex find-and-replace, and backlink detection, with optional compact response mode to reduce token consumption by 40-60% for large vaults.

NasAndNora/obsidian-http-mcp
First HTTP-native MCP server for Obsidian - Compatible with any MCP client (Claude Code, Codex, Gemini, etc.) without stdio bugs
Implements HTTP transport bridging between MCP clients and Obsidian's Local REST API plugin, bypassing stdio reliability issues affecting Claude Code CLI. Features intelligent caching (70% fewer API calls), fuzzy search with typo tolerance, soft-delete protection, and sub-200ms response times even with 1000+ notes. Designed for cross-platform setups (Windows/WSL2/Linux) with straightforward 1-minute configuration using Node.js.
