Best MCP servers for local-first & privacy
Local-first MCP setups keep your data on your own machine: the agent reads and writes files, notes, and code without anything traversing a third-party cloud beyond the model call itself. That matters when you're handling sensitive material, working offline, or simply prefer that your knowledge and source live on disk rather than in someone else's database. The servers below are all local by design, a sandboxed filesystem, a plain-Markdown vault, and your Git repositories, so the agent's reach is bounded to directories you explicitly allow. Combine them to give an agent a complete local workspace it can navigate without external dependencies. Each ships a verified, current install config.
Filesystem
Anthropic (reference)
Reference MCP server for secure local file access: read, write, edit, search, and explore within allowed directories.
The reference filesystem server gives secure local file access, read, write, edit, search, and explore, but only within directories you explicitly allow, so the agent's reach is sandboxed to what you permit.
Obsidian

Let an agent read, search, and edit your Obsidian vault through the Local REST API plugin.
The Obsidian server reads, searches, and edits your local Markdown vault through the Local REST API plugin, keeping your notes as plain text on your own disk rather than in a hosted workspace.
Git
Anthropic (Model Context Protocol)
Reference MCP server for local Git: status, diffs, commits, branches, and history on a repo path.
The reference Git server exposes status, diffs, commits, branches, and history on a local repo path, letting the agent work with your version-controlled code entirely on-machine.
