For stdio, add it to your MCP client config: ```jsonc { "mcpServers": { "better-workspace": { "command": "npx", "args": ["--yes", "@n24q02m/better-workspace-mcp@latest"], "env": { "GOOGLE_OAUTH_CLIENT_ID": ".apps.googleusercontent.com", "GOOGLE_OAUTH_CLIENT_SECRET": "" } } } } ``` Those two values come from an OAuth 2.0 client of type **Desktop app**, created in the [Google Cloud Console](https://console.cloud.google.com/apis/credentials) under APIs & Services → Credentials. Desktop is the right type because the server receives the consent redirect on a [loopback address](https://developers.google.com/identity/protocols/oauth2/native-app), not on a public URL. Enable the Workspace APIs you plan to call on the same project, and add yourself as a test user while the consent screen is unpublished. The first run opens the Google consent screen in your browser; the refresh token is stored encrypted on your machine, so later runs start without asking again. The same server can also serve several people over HTTP -- see [Remote (HTTP mode)](#remote-http-mode). ## Remote (HTTP mode) Besides stdio, the server runs as a multi-user HTTP service. Authentication is OAuth 2.1 delegated to Google, and each user's Google credentials are kept in their own bucket keyed by their JWT `sub`, so one deployment serves several people without them sharing an account. Point your MCP client at the host you deployed it on: ```jsonc { "mcpServers": { "better-workspace": { "type": "http", "url": "https:///mcp" } } } ``` ### Modes Two, and only two. There is no proxy or daemon mode: stdio speaks the MCP stdio transport directly, with no HTTP hop inside it. | Mode | Selected by | Serves | Google OAuth client | | --- | --- | --- | --- | | `stdio` | the default | one user, on their own machine | **Desktop app** | | `http` | `--http`, `MCP_TRANSPORT=http`, or `TRANSPORT_MODE=http` | several users, one credential bucket per JWT `sub` | **Web application** | ### Two OAuth clients, not one Google binds redirect URIs to the *type* of the OAuth client, so the two modes cannot share one: - A **Desktop** client may redirect to any loopback port. That is what stdio needs -- it stands a throwaway consent server on a random port. - A **Web** client may only redirect to URIs registered in advance. That is what a deployment needs, because a public host has no loopback to come back to. Register both of these on the Web client, or the flows that use them fail with `redirect_uri_mismatch`: | Redirect URI | Used by | | --- | --- | | `/callback` | signing in to the server itself (delegated OAuth) | | `/accounts/callback` | `config(action="account_add")` -- adding a second Google account | Keep the two client credentials under separate names. Pointing `GOOGLE_OAUTH_CLIENT_ID`/`_SECRET` at the Web client on a machine that also runs stdio breaks every stdio install, which is why the Cloudflare deploy carries the Web pair as `GOOGLE_OAUTH_WEB_CLIENT_ID`/`_SECRET` and renames it on the way into the container (`src/worker.ts`). ### Environment | Variable | Required | What it does | | --- | --- | --- | | `GOOGLE_OAUTH_CLIENT_ID` | yes | Web client id. The server refuses to start without it. | | `GOOGLE_OAUTH_CLIENT_SECRET` | yes | Web client secret. Same. | | `CREDENTIAL_SECRET` | yes | Derives each subject's credential-encryption key, and the JWT signing key. Without it that signing key would land on a container filesystem that does not survive a restart, so the server refuses to start rather than lose everyone's session on the next deploy. | | `PUBLIC_URL` | in practice | The exact public origin, e.g. `https://`. It is what the redirect URIs above are built from; unset, the server falls back to the `Host` header and the redirect stops matching what Google has registered. | | `MCP_RELAY_PASSWORD` | recommended | One shared password gating `/authorize` behind a login page. Empty disables the gate, which leaves anyone who can reach the host able to start an OAuth flow against your deployment. | | `PORT` | no | Listen port. `0` (the default) asks the OS for a free one. | | `HOST` | no | Bind address. Defaults to loopback, so a container needs `0.0.0.0`. | | `MCP_STORAGE_BACKEND` / `MCP_KV_BASE_URL` | Cloudflare only | Set to `cf-kv` and the worker's internal KV URL when running as a Cloudflare Worker + Container. Left unset, credentials are stored on local disk. | `docker-compose.http.yml` in this repo is these variables written out as a runnable overlay. ## Tools One composite tool per Workspace domain, plus `config` and `help`: | Tool | What it covers | | --- | --- | | `docs` | Google Docs -- `getText`, `create`, `writeText`, `getSuggestions`, `replaceText`, `formatText` | | `drive` | Files and folders -- `search`, `findFolder`, `createFolder`, `moveFile`, `renameFile`, `trashFile`, `downloadFile`, `getComments` | | `calendar` | Events -- `listCalendars`, `listEvents`, `getEvent`, `createEvent`, `updateEvent`, `deleteEvent`, `respondToEvent`, `findFreeTime` | | `gmail` | Mail -- `search`, `get`, `send`, `createDraft`, `sendDraft`, `modify`, `batchModify`, `modifyThread`, `downloadAttachment`, `listLabels`, `createLabel` | | `sheets` | Spreadsheets, read-only -- `getText`, `getRange`, `getMetadata` | | `slides` | Presentations -- 19 actions covering slides, text, shapes, images, tables, and speaker notes | | `tasks` | Task lists and tasks -- `listTaskLists`, `listTasks`, `createTask`, `updateTask`, `completeTask`, `deleteTask` | | `chat` | Google Chat -- `listSpaces`, `findSpaceByName`, `setUpSpace`, `getMessages`, `listThreads`, `sendMessage`, `sendDm`, `findDmByEmail` | | `people` | Profile lookups -- `getMe`, `getUserProfile`, `getUserRelations` | | `forms` | Forms -- `create`, `get`, `batchUpdate`, `listResponses`, `getResponse` | | `time` | Local date/time/timezone helpers (no Google account needed) | | `config` | Credential state and account management | | `help` | Full documentation for any tool | Questions are added to a form with `forms(action="batchUpdate")`, not at `create`; responses are read-only, because the Forms API cannot write one. Listing or deleting forms goes through `drive`. ## Quick start Check that the credentials landed, with the `config` tool. Before the first consent this reports `awaiting_setup`; afterwards it names the account the server is acting as: ```json { "action": "status" } ``` Then call a domain tool. On `docs`, `create` returns the new document's ID, which `getText` reads back: ```json { "action": "create", "title": "Notes", "content": "First line." } { "action": "getText", "documentId": "" } ``` `time`, `config`, and `help` need no Google account, so they answer even before consent -- `time` is the quickest check that the server is wired up at all: ```json { "action": "getCurrentTime" } ``` To act as a second Google account, see [Multi-account](#multi-account). ## Multi-account Every domain tool takes an `account` parameter -- the email of the Google account the call acts as. Omit it and the call runs against the primary account. ```json { "action": "search", "query": "is:unread", "account": "work@example.com" } { "action": "search", "query": "is:unread" } ``` Those two `gmail` calls read two different mailboxes: the first `work@example.com`, the second whichever account is primary. Accounts are managed through the `config` tool: | Call | Effect | | --- | --- | | `config(action="account_add")` | Returns a URL to open; completing the Google consent there adds one more account. | | `config(action="account_list")` | The configured accounts and which one is primary. | | `config(action="account_remove", account="")` | Forget one account. | | `config(action="account_set_default", account="")` | Make one account the primary. | The first account authorized becomes the primary. Removing the primary promotes one of the remaining accounts; removing the last one puts the server back to awaiting setup. Naming an account that is not configured is an error that names it -- the call is never rerouted to the primary, because a silent fallback would act on the wrong mailbox. `account_add` works in both transports and chooses the flow itself: a temporary loopback consent server in stdio, and a fixed `/accounts/callback` on the running server over HTTP, since a Web OAuth client's redirect URI must be registered in advance. The HTTP link is single-use and expires in 10 minutes. `value="primary"` is stdio only. Over HTTP that request would have to ride the URL through Google, where anyone who obtained it could aim your default account at one of theirs -- so remote callers change the default with `account_set_default` instead, from inside an authenticated call. ### Coming from an earlier single-account build Credentials stored by a build from before multi-account support are one flat blob of tokens. The first run afterwards adopts that blob into the multi-account layout under the account's email. The email comes from the stored `id_token` when it is present -- no network needed, and that is the usual case. Otherwise the server asks Google's userinfo endpoint, which needs network access and a token that is still valid or refreshable. If neither works, the server reports itself as awaiting setup and opens the browser OAuth flow even though the stored token may still be fine. Completing that consent works, and nothing is discarded: the account you just authorized is stored and becomes the primary, while the old tokens are carried across under the key `(unidentified)` rather than being overwritten. `config(action="account_list")` then shows two entries: ```json { "accounts": ["(unidentified)", "you@example.com"], "primary": "you@example.com" } ``` Nothing routes to `(unidentified)`: it is never promoted to primary while a real account remains, and no call reaches it unless you name it explicitly. It is there so a credential whose owner could not be determined is not silently thrown away. Remove it once the re-authorized account is working: ```json { "action": "account_remove", "account": "(unidentified)" } ``` After a successful adoption -- the usual case -- `config(action="account_list")` shows exactly one account, and it is the primary. ### Forms scopes and re-consent The consent screen has requested the Google Forms scopes since before the `forms` tool existed, so it arrived without a second trip through consent. Accounts authorized *before* those scopes were added are covered too, but by a different route: Google accepts `https://www.googleapis.com/auth/drive` in place of the Forms scopes for every Forms method this server calls, and full `drive` has been on the consent screen since the first release. Google never widens a token it has already issued, so if a grant covers neither -- a user may withhold individual restricted scopes at the consent screen -- the first `forms` call returns a 403 (`Request had insufficient authentication scopes`). Re-authorize just that account with `config(action="account_add")`, signing in as the same account; the record is replaced in place, so nothing else changes. ## Documentation Docs for the whole MCP server stack are at **[mcp.n24q02m.com](https://mcp.n24q02m.com)**.
