Claude Desktop¶

This guide walks through four progressive setups for using markdown-vault-mcp with Claude Desktop:

Basic — read-only keyword search, no external services
Git write support — enable write/edit/delete with auto-commit
Semantic search — add embedding-based search for better results
MCP Apps views — browse your vault visually with Context Card, Graph Explorer, and more

Each step builds on the previous one. Start with Step 0 (easiest) or Step 1 (full control) and add features as needed.

Step 0: Install via .mcpb bundle¶

Goal: Install markdown-vault-mcp in Claude Desktop with a guided wizard — no JSON editing required.

Prerequisites: Claude Desktop >= 0.10.0.

This is the easiest option for non-technical users.

Install¶

Download the .mcpb file from the GitHub Releases page.
Double-click the downloaded .mcpb file, or run:
```
mcpb install <file>.mcpb
```
Claude Desktop opens a GUI wizard that prompts for the required env vars. No manual JSON editing needed.

Fewer configurable env vars

The .mcpb bundle exposes a curated set of env vars (vault path, read-only mode, embedding provider, and exclude patterns). For full control over all configuration options, use Step 1 instead.

Step 1: Basic read-only setup¶

Goal: Connect a local Obsidian vault to Claude Desktop with keyword search.

Prerequisites: Python 3.10+, Claude Desktop installed.

Install¶

pip install markdown-vault-mcp[all]

Or with uv:

uv tool install markdown-vault-mcp[all]

Configure Claude Desktop¶

Edit your Claude Desktop configuration file:

macOSWindowsLinuxmacOS / LinuxWindows

~/Library/Application Support/Claude/claude_desktop_config.json

%APPDATA%\Claude\claude_desktop_config.json

~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "my-vault": {
      "command": "markdown-vault-mcp",
      "args": ["serve"],
      "env": {
        "MARKDOWN_VAULT_MCP_SOURCE_DIR": "/path/to/your/ObsidianVault",
        "MARKDOWN_VAULT_MCP_SERVER_NAME": "my-vault",
        "MARKDOWN_VAULT_MCP_EXCLUDE": ".obsidian/**,.trash/**",
        "MARKDOWN_VAULT_MCP_INDEX_PATH": "/path/to/store/index.db"
      }
    }
  }
}

{
  "mcpServers": {
    "my-vault": {
      "command": "markdown-vault-mcp",
      "args": ["serve"],
      "env": {
        "MARKDOWN_VAULT_MCP_SOURCE_DIR": "C:\\Users\\YourName\\Documents\\ObsidianVault",
        "MARKDOWN_VAULT_MCP_SERVER_NAME": "my-vault",
        "MARKDOWN_VAULT_MCP_EXCLUDE": ".obsidian/**,.trash/**",
        "MARKDOWN_VAULT_MCP_INDEX_PATH": "C:\\Users\\YourName\\vault_index.db"
      }
    }
  }
}

Replace the paths with the actual locations on your machine.

Persist the index

Setting MARKDOWN_VAULT_MCP_INDEX_PATH stores the FTS5 index on disk. Without it, the index is built in memory on every startup. With it, only changed files are reindexed.

Exclude Obsidian internals

MARKDOWN_VAULT_MCP_EXCLUDE keeps .obsidian/ config files and .trash/ out of search results. Add any other directories you want to skip (e.g., _templates/**).

Restart Claude Desktop¶

Quit and reopen Claude Desktop. The server tools should appear in Claude's tool list.

Verify it works¶

In a Claude Desktop conversation, ask:

Search my vault for "meeting notes"

Claude should use the search tool and return matching documents from your vault. If you get no results, verify that MARKDOWN_VAULT_MCP_SOURCE_DIR points to a directory containing .md files.

Step 2: Enable git write support¶

Goal: Allow Claude to create, edit, delete, and rename notes in managed git mode — with every change auto-committed and pushed.

Prerequisites: Step 1 complete. Your vault directory must be a git repository with an HTTPS remote configured.

Create a GitHub Personal Access Token¶

Go to GitHub Settings > Developer settings > Fine-grained tokens
Set repository access to your vault repository only
Grant Contents: Read and write permission
Copy the token (starts with github_pat_)

Update the configuration¶

Add the highlighted lines to your existing config:

{
  "mcpServers": {
    "my-vault": {
      "command": "markdown-vault-mcp",
      "args": ["serve"],
      "env": {
        "MARKDOWN_VAULT_MCP_SOURCE_DIR": "/path/to/your/ObsidianVault",
        "MARKDOWN_VAULT_MCP_READ_ONLY": "false",
        "MARKDOWN_VAULT_MCP_GIT_REPO_URL": "https://github.com/your-org/your-vault.git",
        "MARKDOWN_VAULT_MCP_GIT_USERNAME": "x-access-token",
        "MARKDOWN_VAULT_MCP_GIT_TOKEN": "github_pat_your_token_here",
        "MARKDOWN_VAULT_MCP_GIT_PUSH_DELAY_S": "60",
        "MARKDOWN_VAULT_MCP_SERVER_NAME": "my-vault",
        "MARKDOWN_VAULT_MCP_EXCLUDE": ".obsidian/**,.trash/**",
        "MARKDOWN_VAULT_MCP_INDEX_PATH": "/path/to/store/index.db"
      }
    }
  }
}

What these do:

READ_ONLY=false — enables the write, edit, delete, and rename tools
GIT_REPO_URL — enables managed mode (clone/remote validation)
GIT_USERNAME / GIT_TOKEN — HTTPS auth for pull/push
GIT_PUSH_DELAY_S=60 — batches rapid writes, pushing after 60 seconds of idle time

Token security

The token is stored in plain text in your Claude Desktop config. Use a fine-grained token scoped to the single vault repository with minimal permissions.

Restart and verify¶

Restart Claude Desktop, then ask:

Create a new note at "test/hello.md" with the content "Hello from Claude!"

Claude should use the write tool. Check your git log to confirm the commit:

cd /path/to/your/ObsidianVault
git log --oneline -3

You should see a commit from markdown-vault-mcp. Delete the test note when done:

Delete the note at "test/hello.md"

Step 3: Add semantic search¶

Goal: Enable embedding-based search alongside keyword search for better recall on conceptual queries.

Prerequisites: Step 1 complete. Choose an embedding backend:

FastEmbed (recommended for Windows and offline use) — local inference, no external service
Ollama (macOS/Linux) — local inference via Ollama
OpenAI — cloud-based, requires API key (see Embeddings guide)

Install and configure¶

FastEmbed (Windows / offline)Ollama (macOS / Linux)

Install the embeddings extra:

pip install "markdown-vault-mcp[embeddings]"
# or:
uv tool install "markdown-vault-mcp[embeddings]"

Update your claude_desktop_config.json:

{
  "mcpServers": {
    "my-vault": {
      "command": "markdown-vault-mcp",
      "args": ["serve"],
      "env": {
        "MARKDOWN_VAULT_MCP_SOURCE_DIR": "C:\\Users\\YourName\\Documents\\ObsidianVault",
        "MARKDOWN_VAULT_MCP_SERVER_NAME": "my-vault",
        "MARKDOWN_VAULT_MCP_EMBEDDINGS_PATH": "C:\\Users\\YourName\\vault_embeddings",
        "MARKDOWN_VAULT_MCP_EMBEDDING_PROVIDER": "fastembed",
        "MARKDOWN_VAULT_MCP_FASTEMBED_MODEL": "BAAI/bge-small-en-v1.5",
        "MARKDOWN_VAULT_MCP_FASTEMBED_CACHE_DIR": "C:\\Users\\YourName\\fastembed_cache",
        "MARKDOWN_VAULT_MCP_INDEX_PATH": "C:\\Users\\YourName\\vault_index.db",
        "MARKDOWN_VAULT_MCP_EXCLUDE": ".obsidian/**,.trash/**"
      }
    }
  }
}

Install and start Ollama:

brew install ollama        # macOS
ollama pull nomic-embed-text

Update your config:

{
  "mcpServers": {
    "my-vault": {
      "command": "markdown-vault-mcp",
      "args": ["serve"],
      "env": {
        "MARKDOWN_VAULT_MCP_SOURCE_DIR": "/path/to/your/ObsidianVault",
        "MARKDOWN_VAULT_MCP_SERVER_NAME": "my-vault",
        "MARKDOWN_VAULT_MCP_EMBEDDINGS_PATH": "/path/to/store/embeddings",
        "MARKDOWN_VAULT_MCP_EMBEDDING_PROVIDER": "ollama",
        "OLLAMA_HOST": "http://localhost:11434",
        "MARKDOWN_VAULT_MCP_OLLAMA_MODEL": "nomic-embed-text",
        "MARKDOWN_VAULT_MCP_EXCLUDE": ".obsidian/**,.trash/**",
        "MARKDOWN_VAULT_MCP_INDEX_PATH": "/path/to/store/index.db"
      }
    }
  }
}

Key env vars:

MARKDOWN_VAULT_MCP_EMBEDDINGS_PATH — where to persist embedding vectors on disk (required to enable semantic search)
MARKDOWN_VAULT_MCP_EMBEDDING_PROVIDER — fastembed, ollama, or openai
MARKDOWN_VAULT_MCP_FASTEMBED_MODEL / MARKDOWN_VAULT_MCP_OLLAMA_MODEL — which model to use

Pre-build embeddings before first launch¶

For large vaults, building embeddings on first startup can take several minutes — long enough for Claude Desktop to time out the connection. Pre-build from the command line instead:

macOS / LinuxWindows (PowerShell)

export MARKDOWN_VAULT_MCP_SOURCE_DIR="/path/to/your/ObsidianVault"
export MARKDOWN_VAULT_MCP_INDEX_PATH="/path/to/store/index.db"
export MARKDOWN_VAULT_MCP_EMBEDDINGS_PATH="/path/to/store/embeddings"
export MARKDOWN_VAULT_MCP_EMBEDDING_PROVIDER="ollama"

markdown-vault-mcp reindex

$env:MARKDOWN_VAULT_MCP_SOURCE_DIR = "C:\Users\YourName\Documents\ObsidianVault"
$env:MARKDOWN_VAULT_MCP_INDEX_PATH = "C:\Users\YourName\vault_index.db"
$env:MARKDOWN_VAULT_MCP_EMBEDDINGS_PATH = "C:\Users\YourName\vault_embeddings"
$env:MARKDOWN_VAULT_MCP_EMBEDDING_PROVIDER = "fastembed"
$env:MARKDOWN_VAULT_MCP_FASTEMBED_MODEL = "BAAI/bge-small-en-v1.5"
$env:MARKDOWN_VAULT_MCP_FASTEMBED_CACHE_DIR = "C:\Users\YourName\fastembed_cache"

markdown-vault-mcp reindex

reindex builds (or updates) both the FTS index and the embedding vectors. Once complete, Claude Desktop will load the pre-built index on startup without needing to re-embed anything.

Subsequent startups are fast

After the initial build, only new or changed files are reindexed. You can run reindex again any time to catch up if you edited files outside Claude.

Restart and verify¶

Restart Claude Desktop, then ask:

Search my vault for notes about "project planning and task management" using hybrid mode

Claude should use the search tool with mode="hybrid". Hybrid search combines keyword (BM25) and semantic (cosine similarity) results using Reciprocal Rank Fusion, giving better results for conceptual queries.

Compare with keyword-only:

Search my vault for "project planning" using keyword mode

Hybrid mode should return more conceptually related notes, even if they don't contain the exact phrase.

Step 4: Use MCP Apps views¶

Goal: Browse your vault visually with the Context Card, Graph Explorer, Vault Browser, and Note Preview views.

Prerequisites: Step 1 complete. A Claude client that supports the MCP Apps protocol (e.g., Claude on claude.ai).

MCP Apps views are automatically available — no extra configuration needed for stdio transport. The server registers two tools (browse_vault and show_context) that open interactive views in supporting clients.

Try it¶

In a Claude conversation, ask:

Browse my vault

Claude should use the browse_vault tool. In an Apps-capable client, this opens an interactive SPA with four tabs:

Context Card — note dossier with backlinks, outlinks, similar notes, and tags
Graph Explorer — interactive force-directed link graph
Vault Browser — searchable file tree
Note Preview — rendered markdown with a "Send to Claude" button

You can also ask for a specific note's context:

Show me the context for "Projects/roadmap.md"

Claude uses the show_context tool to open the Context Card for that note.

Non-Apps clients

Clients that don't support MCP Apps (e.g., Claude Code) receive a text-only summary instead of the interactive view. All the underlying data is still accessible via the get_context, get_backlinks, and other link graph tools.

For full details on views, configuration, and architecture, see the MCP Apps guide.

Firing prompts from Claude.ai's `+` menu¶

This guide covers Claude Desktop. If you also use Claude.ai with the same server, its prompts can be fired from the compose area's + menu once the server is added as a connector. Click +, select connectors, pick the server, pick a prompt — Claude opens with the prompt scaffolded. See How to invoke prompts.
