Best for
  • Obsidian users who want an AI coding-agent chat and inline editor built into their vault
  • Developers already using Claude Code, Codex, or similar CLIs who want vault-aware access to them
  • Note-takers who want agent-assisted file read/write, search, and multi-step workflows scoped to their vault
  • Teams that want an AI assistant to directly operate on GitHub repos and collaboration workflows
  • Users already in the GitHub Copilot ecosystem who want a zero-deployment remote option
Not for
  • Users looking for a standalone MCP server to add tools/resources to an MCP client — Claudian is a client/host, not an MCP server
  • Mobile Obsidian users — the plugin is desktop only (macOS, Linux, Windows)
  • Users without any supported CLI harness (Claude Code, Codex, Grok Build, OpenCode, or Pi) installed and a compatible API/subscription provider
  • Scenarios where you don't want the assistant to have write access to repos (enable only read-only toolsets)
  • Environments with strict network isolation for private repos that can't reach the official remote endpoint
Required permissions
  • Read/write/edit access to files within the Obsidian vault (the agent's working directory)
  • Bash/shell command execution via the underlying CLI harness
  • Network access to the selected AI provider (Anthropic, OpenAI, xAI, or OpenCode/Pi providers) and to any configured MCP server endpoints
  • A personal access token (PAT) or OAuth App token; effective scope depends on the token's own permissions
  • Enabling toolsets like actions/issues/pull_requests grants write access — request tokens on a least-privilege basis
Risks and side effects
  • Broad file read/write and bash access to the vault means a misbehaving or misprompted agent could modify or delete notes
  • Input, attached files, images, and tool outputs are sent to the selected third-party API provider, so sensitive vault content could leave the local machine
  • MCP servers configured within the plugin are additional third-party endpoints whose trustworthiness is outside Claudian's control
  • Write toolsets (creating/merging PRs, triggering workflows) can cause accidental changes if the token is overscoped — try a read-only toolset first
  • In hosted mode, credentials travel via the Authorization header — make sure the client-to-api.githubcopilot.com connection is trusted
