Obsidian MCP server setup for Claude Code and Cursor

Quick answer: The Obsidian MCP server wraps the local filesystem reads and writes as a set of tools Claude Code or Cursor can call over stdio. Install with one npx command, drop in your vault path, and the editor can run real operations against Obsidian. Setup runs about 4 to 6 minutes end to end, tested on mcp-obsidian on April 15, 2026.

Most teams that use Obsidian end up copying data in and out of ChatGPT or Claude to ask questions about it. The MCP server removes that step. When you ask Claude for a summary or an action, it talks to Obsidian itself, reads the response, and writes the answer back without the context swap. For workflows that already live in Obsidian, that feedback loop is the whole reason to wire this up.

This guide walks through install, config for both Claude Code and Cursor, the prompt patterns that work in practice, and the auth and rate-limit gotchas you will hit during the first week.

What this server does

The server speaks MCP over stdio and forwards every tool call to the local filesystem reads and writes using filesystem path for auth. It exposes roughly 8 to 12 tools, grouped into three rough buckets:

• Read and write markdown notes by relative path within the configured vault
• Full-text search across every note body with support for tag filters and folder scoping
• Create new notes from a template with frontmatter injection (title
• Update YAML frontmatter properties on existing notes without rewriting the body
• List files
• Resolve wikilinks and backlinks to traverse related notes

Every tool call reads the vault path from the spawn-time env. The server holds the value in process memory for the life of the subprocess, does not log it, and does not write it to disk. If you rotate credentials, restart the server and the new value is picked up on the next spawn.

The server does not implement a local cache. Every call is a fresh round trip to Obsidian. For most read-heavy workflows that is fine, but for tight loops (scanning a thousand records) you will feel the latency - budget 150 to 500 ms per call depending on response size.

Installing Obsidian MCP

The package is on npm as mcp-obsidian. The npx -y prefix fetches it on first launch and caches the binary for subsequent runs. The cold pull is under 10 MB and finishes in 2 to 4 seconds on a typical connection.

Before touching any config, make sure your Obsidian instance is reachable at the URL you plan to configure. For local setups, start the service on the default port and confirm with a simple health check in a terminal.

Keep any credentials out of files you commit. The rest of this guide assumes the values live in shell env vars named OBSIDIAN_VAULT_PATH.

Configuring for Claude Code

Claude Code reads MCP servers from ~/.claude/mcp.json or a per-project .mcp.json file. Add a obsidian entry that spawns the server with OBSIDIAN_VAULT_PATH in its env:

{
  "mcpServers": {
    "obsidian": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-obsidian"
      ],
      "env": {
        "OBSIDIAN_VAULT_PATH": "/Users/you/Documents/MyVault"
      }
    }
  }
}

Restart Claude Code, then run /mcp in a session to confirm the Obsidian server is attached. Call a read-only tool as a smoke test - if the response comes back with real data from your account, the vault path has the right scope.

For team projects, commit a placeholder version of .mcp.json with ${OBSIDIAN_VAULT_PATH} inside the env value and let each developer provide the real value via their shell profile. Claude Code expands env vars when it spawns the subprocess.

Configuring for Cursor

Cursor uses the same MCP spec and reads from ~/.cursor/mcp.json. The config is identical to the Claude Code block above. Open Cursor settings, navigate to the MCP tab, and toggle the Obsidian server on. Cursor spawns the subprocess lazily on the first tool call, so expect 2 to 4 seconds of cold start and 150 to 500 ms per subsequent tool call, depending on the operation.

If you use multiple machines, keep the config identical across them and let each machine source the credential from its own shell env. That way you never commit a real token to git.

Example prompts and workflows

A few prompts that work reliably once the server is attached:

• "Search my vault for every note tagged #project/mcp and summarize the common themes."
• "Create a new daily note for today from the daily-template.md template and add a task to review PRs."
• "Find backlinks to Claude Code setup.md and list which notes reference it."
• "Update the status frontmatter on projects/site-redesign.md from active to shipped and add today as closed_at."
• "Read meetings/2026-04-10 standup.md and extract every action item into a flat list."

The model will chain calls on its own. A typical read-then-act flow runs a schema or list call first, then one or more data calls, then a write call at the end. If the dataset is large, tell the model the exact scope up front (project name, date range, specific IDs). Scoping down cuts round trips from 6 or 7 calls down to 2 or 3.

One caveat: the model sometimes generates overly broad queries. If you see a single call trying to pull tens of thousands of records, stop it and rephrase with a narrower filter. Obsidian servers tend to slow down sharply past 500 results per page.

Troubleshooting

Tool call returns 401 or auth error. The vault path is wrong, expired, or has been revoked. Regenerate the credential, update your shell env, and restart the MCP server (/mcp restart obsidian in Claude Code).

Tool call returns 403 or permission denied. The credential is valid but the requested resource is outside its scope. Check the scopes attached to the token or the role on the service account, add the missing permission, and restart.

Tool call returns 429 rate limit. Obsidian has per-account or per-route rate limits. The server does not queue on your behalf. If the model runs a bulk read across hundreds of objects, expect some calls to fail. Ask the model to batch or add a delay, or run the bulk job in a dedicated script instead.

Server fails with ENOENT on npx. The npx binary is not on PATH in the env the editor inherits. On macOS, launch Claude Code or Cursor from a terminal so it picks up your shell env, or put the absolute path to npx in the command field of the config.

Tool call returns 422 or schema error. A field or parameter name in the request does not match what Obsidian expects. Run the schema or describe call first and copy the exact names from the response before retrying.

Alternatives

A few options if the Obsidian server does not fit your setup:

• Look for a dedicated server with a narrower surface if you only need one or two operations - smaller servers tend to have faster cold starts.
• Use the official Obsidian CLI or SDK directly from a script when the task is a one-off and the MCP overhead is not worth it.
• Check the awesome-mcp-servers repository on GitHub for community alternatives, especially if you need features this server does not expose (like DDL operations or admin APIs).

For one-off exports, the Obsidian API is straightforward to call from a script. The MCP server pays off when Claude needs to read and write in the same session without you switching to the Obsidian UI. Good use cases include knowledge base search, daily note automation, and extracting structured data from meeting logs.

The Obsidian MCP server is the right default for any workflow already rooted in Obsidian. Four to six minutes of setup replaces hours of copy-paste between your editor and the Obsidian dashboard. Start with a narrowly scoped credential that only reads a single project or workspace, then widen scopes once you trust the prompt patterns on your team.

Security notes

Rotate the vault path on a 90-day cadence as a baseline hygiene practice. If you ever suspect a credential leaked (committed to git, pasted in a screenshot), revoke it in the Obsidian dashboard immediately - the old value stops working within a few seconds and existing subprocesses will fail their next call.

Scope credentials to the smallest set of resources you actually need. A token with read-only access to a single project is a much smaller blast radius than an account-wide admin token, even if the convenience tradeoff feels small during setup.

Performance and cost

Most tool calls complete in 150 to 500 ms on a warm connection. Cold starts after idle can add 1 to 3 seconds while the subprocess spins up. Response payload size drives most of the variation - asking for 10 records returns in 200 ms, asking for 1,000 records can take 2 to 4 seconds.

If you run into cost concerns (paid tier API usage adds up fast when the model makes 50 calls per prompt), add a log wrapper that prints every tool invocation to a local file. Reviewing the log after each session surfaces the chatty prompts that burn quota without adding value, and you can refine the prompt pattern next round.
