unraid-rmcp

Rust MCP server and CLI for Unraid GraphQL operations across NAS, Docker, VM, and storage workflows.

It exposes one MCP tool, unraid, plus the runraid CLI. Agents can inspect array health, disks, Docker containers and logs, VMs, shares, notifications, system metrics, UPS, logs, network settings, plugins, parity history, rclone, remote access, and Unraid Connect through stdio MCP, Streamable HTTP MCP, or direct shell commands.

30-second path: install CRGX, set UNRAID_API_URL and UNRAID_API_KEY, then run crgx unraid-rmcp -- server --json -> start loopback HTTP with UNRAID_RMCP_HOST=127.0.0.1 crgx unraid-rmcp -- serve mcp -> call tools/call with {"action":"server"}.

Status: operational RMCP upstream-client server with the full Unraid GraphQL query and mutation surface. Read actions require unraid:read; writes require unraid:admin. Destructive operations use MCP form elicitation and fail closed when the client cannot obtain user approval. HTTP MCP supports loopback dev mode, static bearer tokens, and Google OAuth through lab-auth. Release binaries and Docker images target linux/amd64 only.

Not for: replacing the Unraid web UI, running arbitrary shell commands, storing API keys for callers, multi-tenant isolation, or passing Unraid API keys through MCP tool arguments.

Naming

| Surface | This repo | |---|---| | Repository | unraid monorepo (unraid-rs/ component) | | Rust crate | unraid-rmcp | | Binary / CLI | runraid | | crates.io package | unraid-rmcp | | CRGX command | crgx unraid-rmcp -- <runraid args> | | Legacy npm package | unraid-rmcp | | MCP tool | unraid | | Config home | ~/.unraid on hosts, /data in containers | | Env prefixes | UNRAID_*, UNRAID_RMCP_* |

This repo is a small naming exception in the RMCP family: MCP/server variables use UNRAID_RMCP_* rather than UNRAID_MCP_* for compatibility with the existing deployment config.

Capabilities And Boundaries

• Read Unraid array state, parity status, disk health, SMART summaries, and capacity.
• Manage array, Docker, VM, notification, plugin, API-key, rclone, onboarding, settings, remote-access, and Unraid Connect state through GraphQL mutations.
• Require MCP form elicitation for destructive operations while allowing ordinary writes to proceed after scope authorization.
• Provide pagination/filtering for MCP list actions and output truncation for large MCP responses.
• Expose the server_summary prompt and unraid://schema/mcp-tool schema resource.
• Provide setup and doctor commands for local plugin/runtime checks.

| This repo owns | Unraid owns | Explicitly out of scope | |---|---|---| | MCP/CLI projection, GraphQL operation selection, response shaping, pagination, auth policy, elicitation policy, setup checks, and prompt/resource metadata. | NAS state, array/docker/VM behavior, GraphQL schema, Unraid API key issuance, remote access, and Connect state. | Arbitrary shell execution, controller UI replacement, credential brokerage, background monitoring, multi-tenant sandboxing, and direct local filesystem writes. |

Install

| Path | Command | Best for | Notes | |---|---|---|---| | CRGX | crgx unraid-rmcp -- --help | Local MCP clients and quick trials. | Resolves the crate from crates.io and downloads the matching GitHub Release binary. | | Cargo install | cargo install unraid-rmcp --locked | Persistent CLI installation. | Builds runraid from the crates.io source package. | | Release installer | curl -fsSL https://raw.githubusercontent.com/dinglebear-ai/unraid/main/unraid-rs/scripts/install.sh \| bash | Host installs without CRGX. | Installs runraid for linux/amd64. | | Docker / Compose | docker compose up -d | Shared HTTP MCP deployments. | Reads .env and exposes container port 40010. | | Build from source | cargo build --release | Development and audits. | Produces target/release/runraid. | | Plugin | claude plugin install agents/unraid-rs | Claude Code local plugin setup from this checkout. | Ships the skill and local runtime metadata. No hooks — run runraid setup plugin-hook once to provision credentials. |

CRGX / crates.io

Run the stdio MCP server or CLI without installing Node or compiling Rust:

crgx unraid-rmcp -- --help
crgx unraid-rmcp -- mcp
crgx unraid-rmcp -- server --json

CRGX resolves unraid-rmcp from crates.io, reads its cargo-binstall metadata, and downloads the matching runraid archive from the component-prefixed GitHub Release. Exact crate versions can be pinned with unraid-rmcp@<version>.

The npm launcher remains available only as a compatibility path for existing installations; new MCP configurations should use CRGX.

Build From Source

git clone https://github.com/dinglebear-ai/unraid
cd unraid-mcp/unraid-rs
cargo build --release
./target/release/runraid --help

Minimum supported Rust version: 1.90.

Quickstart

1. Configure Unraid

Create an Unraid API key in Settings -> API Management, then set:

export UNRAID_API_URL="https://10-1-0-2.<hash>.myunraid.net:31337/graphql"
export UNRAID_API_KEY="your-api-key-here"

Set UNRAID_API_SKIP_TLS_VERIFY=true only when your Unraid GraphQL endpoint uses a certificate your host does not trust.

2. Run A Safe CLI Call

crgx unraid-rmcp -- server --json

3. Start Loopback HTTP MCP

UNRAID_RMCP_HOST=127.0.0.1 crgx unraid-rmcp -- serve mcp

In another shell:

curl -sf http://127.0.0.1:40010/health

4. Make A First MCP Call

curl -s -X POST http://127.0.0.1:40010/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"unraid","arguments":{"action":"server"}}}'

Client Configuration

Claude Code Stdio

{
  "mcpServers": {
    "unraid": {
      "command": "crgx",
      "args": ["unraid-rmcp", "--", "mcp"],
      "env": {
        "UNRAID_API_URL": "https://10-1-0-2.<hash>.myunraid.net:31337/graphql",
        "UNRAID_API_KEY": "your-api-key-here"
      }
    }
  }
}

Claude Code HTTP

{
  "mcpServers": {
    "unraid": {
      "type": "http",
      "url": "http://127.0.0.1:40010/mcp",
      "headers": {
        "Authorization": "Bearer ${UNRAID_RMCP_TOKEN}"
      }
    }
  }
}

Codex / Labby Gateway

Register Unraid through Labby as an HTTP upstream when sharing one long-running server, or run it directly as stdio for local-only use.

[mcp_servers.unraid]
command = "crgx"
args = ["unraid-rmcp", "--", "mcp"]

Generic MCP JSON

{
  "command": "runraid",
  "args": ["mcp"],
  "env": {
    "UNRAID_API_URL": "https://10-1-0-2.<hash>.myunraid.net:31337/graphql",
    "UNRAID_API_KEY": "your-api-key-here"
  }
}

Do not put UNRAID_API_KEY, OAuth secrets, passwords, SSH keys, or upstream bearer tokens in MCP tool arguments. Use env, config files, or the MCP client's secret storage. MCP callers never provide credentials, tokens, keys, or secrets as action arguments.

Configuration

Host installs read ~/.unraid/.env before loading config. Containers read /data/.env. Process environment overrides both.

| Variable | Default | Purpose | |---|---|---| | UNRAID_API_URL | unset | Full Unraid GraphQL endpoint URL. | | UNRAID_API_KEY | unset | API key for the x-api-key header. | | UNRAID_API_SKIP_TLS_VERIFY | false | Skip TLS certificate verification for self-signed endpoints. | | UNRAID_RMCP_HOST | 0.0.0.0 | HTTP bind host. | | UNRAID_RMCP_PORT | 40010 | HTTP bind port. | | UNRAID_RMCP_SERVER_NAME | unraid-rmcp | Advertised MCP server name. | | UNRAID_RMCP_TOKEN | unset | Static bearer token for HTTP MCP. | | UNRAID_RMCP_NO_AUTH | false | Disable auth only for loopback development. | | UNRAID_RMCP_DISABLE_HTTP_AUTH | false | Compatibility alias for disabling auth. | | UNRAID_NOAUTH | false | Trust an upstream gateway to enforce auth. | | UNRAID_RMCP_ALLOWED_HOSTS | unset | Extra accepted Host header values. | | UNRAID_RMCP_ALLOWED_ORIGINS | unset | Extra accepted CORS origins. | | UNRAID_RMCP_PUBLIC_URL | unset | Public URL for OAuth metadata. | | UNRAID_RMCP_AUTH_MODE | bearer | bearer or oauth. | | UNRAID_RMCP_GOOGLE_CLIENT_ID | unset | Google OAuth client ID. | | UNRAID_RMCP_GOOGLE_CLIENT_SECRET | unset | Google OAuth client secret. | | UNRAID_RMCP_AUTH_ADMIN_EMAIL | unset | Admin email for OAuth bootstrap. |

Authentication

Stdio MCP runs as a local trusted child process and does not use HTTP auth.

HTTP MCP auth policy:

| State | Condition | Behavior | |---|---|---| | Loopback dev | UNRAID_RMCP_HOST starts with 127. or auth is explicitly disabled on loopback | Local unauthenticated development is allowed. | | Mounted bearer | Non-loopback with UNRAID_RMCP_TOKEN | Requires Authorization: Bearer <token> and action scopes. | | Mounted OAuth | UNRAID_RMCP_AUTH_MODE=oauth | Uses Google OAuth/JWT through lab-auth. | | Trusted gateway | UNRAID_NOAUTH=true | Assumes a reverse proxy or gateway already enforced auth. |

Read actions require unraid:read; mutating actions require unraid:admin. Configured static bearer tokens are operator credentials and receive admin scope. OAuth clients receive the scopes granted by the authorization flow.

Safety And Trust Model

• Unraid API keys are loaded from config/env only.
• MCP callers select actions and arguments, not upstream credentials.
• Destructive actions issue an MCP form-elicitation request before dispatch. A decline, cancellation, malformed response, or client without elicitation support stops the operation before the GraphQL request is sent.
• Ordinary mutations remain directly available after unraid:admin authorization; the server does not add a second confirmation parameter or disable writes.
• log_file reads through the Unraid GraphQL API, not arbitrary local files.
• Non-loopback HTTP deployments must use bearer auth, OAuth, or a trusted authenticated gateway.
• This bridge does not sandbox Unraid itself. Unraid remains responsible for API permissions and GraphQL response semantics.

Distribution Contract

• Cargo.toml, Cargo.lock, both version and binaryVersion in packages/unraid-rmcp/package.json, .release-please-manifest.json, agent manifests, and server.json must agree on the released version.
• crates.io publishes lab-auth first and unraid-rmcp second through .github/workflows/crates-publish.yml; automatic publication stays disabled until CRATES_IO_PUBLISHING_ENABLED=true and the crates-io environment holds CARGO_REGISTRY_TOKEN.
• GitHub Releases publish the linux/amd64 runraid archive consumed by CRGX and cargo-binstall through the manifest metadata in Cargo.toml.
• The npm package remains a compatibility surface only. Automatic npm publishing is enabled only when NPM_TRUSTED_PUBLISHING_ENABLED=true.
• Docker/OCI metadata uses ghcr.io/dinglebear-ai/unraid-rmcp:<version>.
• agents/unraid-rs/.mcp.json must launch crgx unraid-rmcp -- mcp so stdio clients resolve the crates.io package without requiring Node.
• The root README is curated. docs/INVENTORY.md is the curated inventory for actions, CLI commands, env vars, HTTP endpoints, and dependencies.

Development

cargo fmt --check
cargo test
cargo clippy -- -D warnings
cargo build --release
npm --prefix packages/unraid-rmcp run check

Verification

python3 /home/jmagar/workspace/soma/scripts/check-readme-guide.py README.md
npm --prefix packages/unraid-rmcp run check
cargo check
cargo test
git diff --check

Runtime smoke:

UNRAID_API_URL=https://10-1-0-2.<hash>.myunraid.net:31337/graphql \
UNRAID_API_KEY=... \
runraid server --json

HTTP smoke:

UNRAID_RMCP_HOST=127.0.0.1 runraid serve mcp
curl -sf http://127.0.0.1:40010/health

Deployment

Use loopback for local development:

UNRAID_RMCP_HOST=127.0.0.1 runraid serve mcp

Use Docker Compose for shared HTTP deployment:

cp .env.example .env
docker compose up -d

When binding to a non-loopback address, configure UNRAID_RMCP_TOKEN, UNRAID_RMCP_AUTH_MODE=oauth, or UNRAID_NOAUTH=true behind an authenticated gateway.

Troubleshooting

| Symptom | Check | |---|---| | UNRAID_API_URL or UNRAID_API_KEY is missing | Set it in env or ~/.unraid/.env. | | TLS errors against Unraid | Set UNRAID_API_SKIP_TLS_VERIFY=true only for self-signed endpoints. | | HTTP /mcp returns unauthorized | Set UNRAID_RMCP_TOKEN and send Authorization: Bearer <token>. | | Stdio client hangs or logs JSON errors | Ensure client config runs unraid-rmcp mcp, not the default HTTP server mode. | | Large list response is truncated | Use limit, offset, name, or state filters on MCP list actions. | | docker_logs fails | Pass a valid container id and optional tail. |
