Common questions

Is DataToRAG safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Google Workspace, Jira, Confluence and Notion for Claude and other MCP clients, through one endpoint.

DataToRAG is an open-source Model Context Protocol gateway. You point your AI client at one URL. Each person connects their own Google, Atlassian and Notion accounts, and the gateway hands the client the tools for those accounts, calling the services with the person's own OAuth grant. It runs hosted at datatorag.com, or on your own infrastructure under the MIT license.

Try it in 60 seconds

Setup is two connections, and both are needed:

Connect your accounts. Sign in at datatorag.com/dashboard and connect Google, Atlassian or Notion. Google's consent screen arrives with every box unticked: tick "Select all", or the services you want.
Connect your AI client to https://datatorag.com/mcp, then sign in with the same email when the client asks.

Claude (web and Desktop). Customize, then Connectors, then Add, then "Add custom connector". Paste the URL and leave the advanced OAuth fields empty.

Claude Code.

claude mcp add --transport http datatorag https://datatorag.com/mcp

Cursor and other clients that take a JSON config.

"mcpServers": { "datatorag": { "url": "https://datatorag.com/mcp" } } }

ChatGPT. Settings, then Connectors, enable Developer mode, then Create, and paste the URL.

The getting started guide has screenshots of each step. Every client connects with OAuth.

The server is listed in the official MCP registry as com.datatorag/mcp-gateway; server.json is the listing.

Screenshots

The agent in the dashboard runs the same tools against your connected accounts, with no client setup.

An upload link takes one file from your computer, up to 25 MB, and answers its size and SHA-256.

The status page shows the latest end-to-end run against production, by service.

Connectors

Tool counts are from the code as of October 2026: 133 tools in the three connectors, and 10 built into the gateway.

Connector	Tools	Services	Docs
Google Workspace (`plugins/gws-mcp`)	87	Gmail, Calendar, Drive, Docs, Sheets, Slides, Contacts, Tasks	docs
Atlassian (`plugins/atlassian-mcp`)	28	Jira, Confluence	docs
Notion (`plugins/notion-mcp`)	18	Pages, databases, comments	docs
Gateway built-ins	10	Connected accounts, skills, file upload and download links, a connectivity check	docs

The three connectors live in this repository under plugins/ and ship inside the gateway's image. A client only sees the tools for services its user has connected.

What makes it different

Several accounts per service. Connect a work and a personal Google account, or two Notion workspaces, under one login, and pick a default. Every connector tool takes an account argument to choose one (how we built it).

Responses sized for a context window. Tools return what the model needs rather than the raw API response. A two-page Google Doc comes back as 2 to 3 KB of text instead of 50 KB or more of JSON (the write-up).

OAuth per user. Each person grants access to their own accounts, and the gateway refreshes the grants. A connector receives only the calling user's access token, never a shared credential.

Files move between services without passing through the chat. A file reference names an email, an attachment or a Drive file, and the gateway carries it to Jira, Drive or an email in one call, answering with its size and SHA-256. Files from your computer arrive through a single-use upload link (file references).

Skills. Ready-made workflows, such as a morning brief or inbox triage, that run in the dashboard, on a schedule, or from any client as MCP prompts (skills, announcement).

A public status page. A test run calls the tools on production the way a user would and publishes what works, by service (status).

Architecture

In text:

Client. Any MCP client sends Streamable HTTP to POST /mcp with a bearer token: an OAuth access token from the gateway's own authorization server, the only credential it accepts.
Gateway (apps/gateway, one Node.js process: Express plus Next.js). It authenticates the bearer, opens or reuses the session, and answers tools/list from the tools table in Postgres, filtered to the services the user has connected. A tools/call is split on __ into the plugin and the tool, the user's token for that service is resolved (and refreshed if expired), and the call is forwarded to the plugin. Every call is metered. The same process serves the dashboard and its agent, the docs, the changelog and the status page.
Built-ins. list_connected_accounts, skills_*, file_upload_link and file_download_link are answered by the gateway itself, with no plugin and no registry row.
Plugins. Each connector is an MCP server under plugins/. The gateway starts each one as a child process under its own non-root account, with an environment of PATH, NODE_ENV and PORT only, and passes the user's token on each call in the X-User-Token header. A crashing plugin is restarted up to three times a minute, and /health reports each plugin as up or down.
Registry. Postgres holds users, connected accounts, provider tokens and the tool registry (name, description and input schema for each plugin tool). Changes to the registry in production are SQL files under registry/, applied by the registry workflow after an approval.

Self-hosting

Prerequisites

Node.js 20 or later and pnpm 9.
A Postgres database, and its connection string as DATABASE_URL. Any Postgres works; nothing here starts one for you.
An OAuth client for each provider you want: Google (one client for sign-in, a second for Workspace scopes), Atlassian, Notion.

Run the gateway

pnpm install

pnpm -r --filter "./packages/*" run build # the gateway reads these packages' built output

cp .env.example .env # then fill in DATABASE_URL, CONNECTION_TOKEN_KEYS and the OAuth clients pnpm --filter @datatorag-mcp/db db:migrate # schema changes are never applied on start

pnpm dev:gateway

The gateway listens on http://localhost:8285 (set by GATEWAY_PORT):

Path	What it is
`/mcp`	The MCP endpoint
`/dashboard`	Sign in, connect accounts, the agent
`/docs/getting-started`	The docs
`/health`	Liveness, and each plugin's state
`/.well-known/oauth-authorization-server`	OAuth metadata for MCP clients

On a laptop the gateway loads plugins from ~/.datatorag/plugins, or from DATATORAG_PLUGINS_DIR when it is set. Build them with pnpm --filter @datatorag-mcp/gws-mcp run build (and the same for atlassian-mcp and notion-mcp).

Environment variables

The full list, with comments, is in .env.example, and the schema that validates it is packages/config/src/index.ts. The ones a self-host needs:

Variable	Purpose
`DATABASE_URL`	Postgres connection string. Required
`CONNECTION_TOKEN_KEYS`	Keys the provider tokens are encrypted with: `:` , comma separated, the first encrypts and all decrypt. Required; make one with `openssl rand -base64 32`
`GATEWAY_PORT`, `GATEWAY_BASE_URL`	Port, and the public URL OAuth redirects are built from
`GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`	Google sign-in for the dashboard
`GOOGLE_GWS_CLIENT_ID`, `GOOGLE_GWS_CLIENT_SECRET`	Google Workspace connections
`ATLASSIAN_CLIENT_ID`, `ATLASSIAN_CLIENT_SECRET`	Jira and Confluence connections
`NOTION_OAUTH_CLIENT_ID`, `NOTION_OAUTH_CLIENT_SECRET`	Notion connections
`SLACK_CONNECTOR_CLIENT_ID`, `SLACK_CONNECTOR_CLIENT_SECRET`, `SLACK_CONNECTOR_TEAM_ID`	Slack connections, for one workspace and admins only; optional
`ANTHROPIC_API_KEY`, `PLAYGROUND_MODEL`	The dashboard agent; empty turns it off
`STRIPE_*`	Billing; optional
`POSTHOG_API_KEY`, `SLACK_BOT_TOKEN`, `BREVO_API_KEY`	Analytics, notifications and email; each is off when empty

Production

Production runs the image built from apps/gateway/Dockerfile, which carries the three plugins. A merge to main builds and publishes it (build.yml), and a deploy is dispatched by hand and approved (release.yml), starting it with docker/docker-compose.prod.yml.
