## MCP Tools & Resources
This MCP server exposes the following tools and resources to AI assistants:
### Tools
| Tool | Description | Parameters |
| -------------------------- | ------------------------------------------------- | -------------------------------------- |
| `get_note_content` | Retrieve content and metadata of an Obsidian note | `filePath` (string) - Path to the note |
| `obsidian_search` | Search notes using a query string | `query` (string) - Search query |
| `obsidian_semantic_search` | Semantic search for notes | `query` (string) - Search query |
### Resources
| Resource | URI Pattern | Description |
| ------------- | ------------------- | ------------------------------------------------------------- |
| Obsidian Note | `obsidian://{path}` | Access notes via URI (e.g., `obsidian://Daily/2025-01-16.md`) |
### Quick Test
```bash
# 1. Set your Obsidian API key
export OBSIDIAN_API_KEY="your-obsidian-rest-api-key"
# 2. Add MCP server and test (Claude Code)
claude mcp add obsidian -- bunx -y @oleksandrkucherenko/mcp-obsidian
claude "Search my Obsidian vault for monitoring tools, summarize findings"
# 2. Alternative: Codex CLI
codex mcp add obsidian --command "bunx -y @oleksandrkucherenko/mcp-obsidian"
codex "Find notes about logging frameworks and create a comparison table"
```
**Example use-case:** *"Find all tools in my Obsidian vault for tracking logs and metrics, make a summary report"* — the AI searches your vault, finds notes about OpenTelemetry, Datadog, Prometheus, etc., and generates a structured summary.
For other CLI tools (Gemini, OpenCode, Kilo Code, Copilot), see [Manual Testing Guide](./docs/04_manual_testing.md#quick-test-commands).
## Configure MCP
### Multi-URL Configuration (Recommended)
**Use `API_URLS` for automatic failover and self-healing.** The server tests all URLs in parallel, selects the fastest one, and automatically reconnects on failure.
```jsonc
{
"mcpServers": {
"obsidian": {
"command": "docker",
"args": [
"run",
"--name", "mcp-obsidian",
"--rm",
"-i", // Keep STDIN open for stdio transport
"-p", "3000:3000",
"-e", "API_KEY",
"-e", "API_URLS",
"-e", "DEBUG", // for logs
"ghcr.io/oleksandrkucherenko/obsidian-mcp:latest"
],
"env": {
"API_KEY": "<secret_key>",
// JSON array - automatically tests and selects fastest URL
"API_URLS": "[\"https://127.0.0.1:27124\",\"https://172.26.32.1:27124\",\"https://host.docker.internal:27124\"]",
"DEBUG": "mcp:*"
}
}
}
}
```
**Self-Healing Features:**
- ✅ Parallel URL testing on startup
- ✅ Automatic selection of fastest URL
- ✅ Health monitoring every 30 seconds
- ✅ Automatic failover on connection loss
- ✅ Exponential backoff to prevent thrashing
**Available transports:**
- `stdio` - Standard input/output (default, best for local MCP clients)
- `http` - HTTP JSON-RPC with SSE streaming (best for remote access)
**WSL2 Example:**
```bash
# Automatically determine WSL gateway IP
export WSL_GATEWAY_IP=$(ip route show | grep -i default | awk '{ print $3}')
# Configure with multiple fallback URLs
API_URLS='["https://127.0.0.1:27124", "https://'$WSL_GATEWAY_IP':27124", "https://host.docker.internal:27124"]'
```
### HTTP Transport Configuration
The MCP server supports HTTP transport for remote access with automatic URL failover:
```jsonc
{
"mcpServers": {
"obsidian-http": {
"command": "docker",
"args": [
"run",
"--name", "mcp-obsidian-http",
"--rm",
"-p", "3000:3000",
"-e", "API_KEY",
"-e", "API_URLS",
"-e", "MCP_HTTP_PATH",
"ghcr.io/oleksandrkucherenko/obsidian-mcp:latest"
],
"env": {
"API_KEY": "<secret_key>",
"API_URLS": "[\"https://127.0.0.1:27124\",\"https://172.26.32.1:27124\",\"https://host.docker.internal:27124\"]",
"MCP_HTTP_PATH": "/mcp" // endpoint path (default is: /mcp)
}
}
}
}
```
#### Decoupled Configuration with Authentication
```bash
# Automatically determine WSL gateway IP
export WSL_GATEWAY_IP=$(ip route show | grep -i default | awk '{ print $3}')
# Configure with multiple fallback URLs
API_URLS='["https://127.0.0.1:27124", "https://'$WSL_GATEWAY_IP':27124", "https://host.docker.internal:27124"]'
# run MCP server on docker separately from IDE
docker run --name mcp-obsidian-http --rm \
-p 3000:3000 \
-e API_KEY="<secret_key>" \
-e API_URLS="${API_URLS}" \
-e MCP_HTTP_TOKEN=<your-secret-token-here> \
ghcr.io/oleksandrkucherenko/obsidian-mcp:latest
```
```jsonc
{
"mcpServers": {
"obsidian": {
"type": "streamable-http",
"url": "http://localhost:3000/mcp",
"headers": {
"Authorization": "Bearer <your-secret-token-here>"
}
}
}
}
```
Clients must include the Authorization header:
```http
Authorization: Bearer your-secret-token-here
```
### Stdio Transport Configuration
For local development with stdio transport (default):
```jsonc
{
"mcpServers": {
"obsidian": {
"command": "docker",
"args": [
"run",
"--name", "mcp-obsidian-windsurf",
"--interactive",
"--rm",
"-e", "API_KEY",
"-e", "API_URLS",
"-e", "DEBUG",
"ghcr.io/oleksandrkucherenko/obsidian-mcp:latest"
],
"env": {
"API_KEY": "<secret_key>",
"API_URLS": "[\"https://127.0.0.1:27124\",\"https://172.26.32.1:27124\"]",
"DEBUG": "mcp:*" // default: disabled logs
}
}
}
}
```
- `--rm` - Automatically remove the container and its associated anonymous volumes when it exits
- `-i, --interactive` - Keep STDIN open
- `-e, --env` - Set environment variables
- `--name string` - Assign a name to the container
- `-p, --publish` - Publish container port to host
- [NPM Package Releases](https://github.com/OleksandrKucherenko/mcp-obsidian-via-rest/pkgs/npm/mcp-obsidian)
- [Docker Image Releases](https://github.com/OleksandrKucherenko/mcp-obsidian-via-rest/pkgs/container/obsidian-mcp)
### Legacy Single-URL Configuration
For backward compatibility, you can still use single-URL configuration with `API_HOST` and `API_PORT`:
```jsonc
{
"mcpServers": {
"obsidian": {
"command": "docker",
"args": [
"run",
"--name", "mcp-obsidian",
"--rm",
"-i",
"-e", "API_KEY",
"-e", "API_HOST",
"-e", "API_PORT",
"ghcr.io/oleksandrkucherenko/obsidian-mcp:latest"
],
"env": {
"API_KEY": "<secret_key>",
"API_HOST": "https://172.26.32.1", // single URL without failover
"API_PORT": "27124"
}
}
}
}
```
**Note:** Single-URL configuration does not provide automatic failover or health monitoring. Use `API_URLS` for production deployments.
### Health Endpoint
When HTTP transport is enabled, the server exposes a health check endpoint at `/health`:
```bash
curl http://localhost:3000/health
```
**Response:**
```json
{
"status": "healthy",
"timestamp": "2025-01-12T12:00:00.000Z",
"transport": "http",
"authEnabled": false
}
```
For comprehensive health status including Obsidian API connection and all transports, you can use the `getHealthStatus()` function which returns:
```json
{
"healthy": true,
"obsidian": {
"connected": true,
"url": "https://obsidian:27124",
"lastCheck": 1705065600000
},
"transports": {
"stdio": { "running": true, "enabled": true },
"http": { "running": true, "enabled": true }
},
"uptime": 3600,
"timestamp": 1705065600000
}
```

## Setup and Troubleshooting
### Setup
- Run [Obsidian Desktop Application](https://obsidian.md/) and enable [Local REST API](https://github.com/coddingtonbear/obsidian-local-rest-api) in Settings.
This setting will allow you to connect to the Local REST API from any network interface (not only localhost, which is critical for WSL2 setup).
- Copy the API Key from Obsidian Settings; you will need it for the MCP configuration.
- Verify that the Obsidian Local REST API is running and accessible from your machine.
- Next Step is always to verify the network setup on your machine (firewall rules, etc).
### Verify that the Obsidian REST API is running (Windows Host, MacOS, Linux)
Run in Windows CMD terminal:
```shell
# windows CMD, verify that port is listening (that rest api is running)
netstat -an | findstr 27124
# Expected output:
# TCP 0.0.0.0:27124 0.0.0.0:0 LISTENING
# Verify that Obsidian Local REST API is working
curl --insecure https://localhost:27124
wget --no-check-certificate -S https://localhost:27124
http --verify=no https://localhost:27124
```
Expected REST API response:
```json
{
"status": "OK",
"manifest": {
"id": "obsidian-local-rest-api",
"name": "Local REST API",
"version": "3.2.0",
"minAppVersion": "0.12.0",
"description": "Get, change or otherwise interact with your notes in Obsidian via a REST API.",
"author": "Adam Coddington",
"authorUrl": "https://coddingtonbear.net/",
"isDesktopOnly": true,
"dir": ".obsidian/plugins/obsidian-local-rest-api"
},
"versions": {
"obsidian": "1.8.10",
"self": "3.2.0"
},
"service": "Obsidian Local REST API",
"authenticated": false
}
```
### WSL2, Docker hosted on Ubuntu
```mermaid
graph LR
subgraph "Windows Machine"
obs("Obsidian Application")
subgraph "WSL2"
subgraph "Ubuntu"
subgraph "Docker"
mcp("mcp-obsidian:latest")
end
end
end
firewall(["Windows Firewall"]) -->|27124| obs
mcp -->|https://$WSL_GATEWAY_IP:27124| firewall
IDE -.->|MCP Server Tools| mcp
end
```
Run inside the WSL2 Ubuntu Terminal:
```bash
export WSL_GATEWAY_IP=$(ip route show | grep -i default | awk '{ print $3}')
echo $WSL_GATEWAY_IP # expected something like: 172.26.32.1
# Verify that Obsidian Local REST API is working
curl --insecure https://$WSL_GATEWAY_IP:27124
wget --no-check-certificate -S https://$WSL_GATEWAY_IP:27124
http --verify=no https://$WSL_GATEWAY_IP:27124
```
### Verify Windows Firewall
Run GUI and Setup Manual The Rules:
```shell
# Windows Defender Firewall / Inbound Rules. Press Win+R and type WF.msc or firewall.cpl
WF.msc
firewall.cpl # and then press 'Advanced settings'
```
Or Run in Windows PowerShell as Administrator:
```shell
# Add firewall rule to allow port 27124 (Run in Admin PowerShell)
New-NetFirewallRule -DisplayName "WSL2 Obsidian REST API" -Direction Inbound -LocalPort 27123,27124 -Protocol TCP -Action Allow
```
Or Run in Windows CMD terminal:
```shell
# check firewall rules (CMD) that manage 27124 port
netsh advfirewall firewall show rule name=all | findstr /C:"Rule Name" /C:"LocalPort" /C:"RemotePort" | findstr /C:"27124"
# display rules that has WSL2 keyword in own name
netsh advfirewall firewall show rule name=all | grep -A 13 WSL2
# display rule definition by port number (4 line after, 9 lines before)
netsh advfirewall firewall show rule name=all | grep -A 4 -B 9 27124
```
### Disable/Enable Firewall
Execute in Windows PowerShell as Administrator:
```shell
# Temporarily turn off firewall (for testing ONLY, not recommended for regular use)
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
# Restore Firewall state
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled True
```
### Verify Connectivity on BusyBox Container
These steps allow us to confirm that the network setup is correct and the container can connect to the Local REST API.
Execute inside the WSL2 Ubuntu terminal:
```bash
export WSL_GATEWAY_IP=$(ip route | grep default | awk '{print $3}')
echo "Windows host IP from WSL2: $WSL_GATEWAY_IP"
# Output:
# Windows host IP from WSL2: 172.26.32.1
# run docker container to verify the connectivity from Docker inside
docker run --rm -it --network=host busybox sh
# inside the container run:
which wget
# /bin/wget
export WINDOWS_HOST_IP="172.26.32.1"
echo $WINDOWS_HOST_IP
# 172.26.32.1
# try to connect to the Local REST API
wget -qO- --no-check-certificate "https://$WINDOWS_HOST_IP:27124"
wget -qO- --no-check-certificate https://172.26.32.1:27124
```
