Second Brain Bridge is a Model Context Protocol (MCP) server: Search and reason over your Obsidian-style Markdown vault, right from ChatGPT. In practice that means any MCP-compatible AI assistant can call Second Brain Bridge's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://secondbrainbridge.vercel.app/mcp and you're connected, with nothing to install locally. The current release is v1.3.0, published under the MIT license, with source at IsaiahDupree/second-brain-bridge on GitHub.
Second Brain Bridge is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
