Describe the whole flow and it is built, tested on every scenario and kept running. Slack **15** triggers Slack **60** actions Gmail **2** triggers Gmail **41** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want Slack and Gmail to do together? Give your AI client this address. `https://mcp.apiant.ai` One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Zed Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Codex and the ChatGPT desktop app Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Any other MCP client Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) Connecting Gmail and Slack lets mail that lands in your inbox show up where the team already talks, and lets Slack activity leave a trace in Gmail. You can post incoming messages to a channel, label them once they are shared, draft replies from Slack messages, and email people who join a channel.

Use when you need to efficiently remove large numbers of emails (e.g., retention enforcement, mailbox hygiene). Use GMAIL_MOVE_TO_TRASH instead when reversibility may be needed. Always obtain explicit user confirmation and verify a sample of message IDs before executing. High-volume calls may trigger 429 rateLimitExceeded or 403 userRateLimitExceeded errors; apply exponential backoff. - Action **Batch Modify Messages** Modify labels on multiple Gmail messages in one efficient API call.

To add/remove labels from specific messages, use GMAIL_ADD_LABEL_TO_EMAIL action instead. - Action **Delete Message** Permanently deletes a specific email message by its id from a gmail mailbox; for `user id`, use 'me' for the authenticated user or an email address to which the authenticated user has delegated access. - Action **Delete Thread** Tool to immediately and permanently delete a specified thread and all its messages. This operation cannot be undone. Use threads.trash instead for reversible deletion. - Action **Fetch Emails** Fetches a list of email messages from a gmail account, supporting filtering, pagination, and optional full content retrieval. - Action **Fetch Message By Message Id** Fetches a specific email message by its id, provided the `message id` exists and is accessible to the authenticated `user id`. - Action **Fetch Message By Thread Id** Retrieves messages from a gmail thread using its `thread id`, where the thread must be accessible by the specified `user id`. - Action **Forward Message** Forward an existing Gmail message to specified recipients, preserving original body and attachments. Verify recipients and content before forwarding to avoid unintended exposure. Bulk forwarding may trigger 429/5xx rate limits; keep concurrency to 5–10 and apply backoff.

Use this to retrieve label information including name, type, visibility settings, message/thread counts, and color. - Action **Get People** Retrieves either a specific person's details (using `resource name`) or lists 'other contacts' (if `other contacts` is true), with `person fields` specifying the data to return. - Action **Get Profile** Retrieves key gmail profile information (email address, message/thread totals, history id) for a user. - Action **Import Message** Tool to import a message into the user's mailbox with standard email delivery scanning and classification. Use when you need to add an existing email to a Gmail account without sending it through SMTP. This method doesn't perform SPF checks, so it might not work for some spam messages. - Action **Insert Message** Tool to insert a message into the user's mailbox similar to IMAP APPEND. Use when you need to add an email directly to a mailbox bypassing most scanning and classification. This does not send a message. - Action **List Drafts** Retrieves a paginated list of email drafts from a user's gmail account. use verbose=true to get full draft details including subject, body, sender, and timestamp. - Action **List History** Tool to list Gmail mailbox change history since a known startHistoryId.

Use when you need to get details about a send-as email address including display name, signature, SMTP settings, and verification status. Fails with HTTP 404 if the specified address is not a member of the send-as collection. - Action **Untrash Message** Tool to remove a message from trash in Gmail. Use when you need to restore a previously trashed email message. - Action **Untrash Thread** Tool to remove a thread from trash in Gmail. Use when you need to restore a deleted thread and its messages. - Action **Update Draft** Updates (replaces) an existing Gmail draft's content in-place by draft ID. This action replaces the entire draft content with the new message - it does not patch individual fields. All fields are optional; if not provided, you should provide complete draft content to avoid data loss. - Action **Update Label** Tool to update the properties of an existing Gmail label. Use when you need to modify label name, visibility settings, or color. ## Each app on its own - [ **Slack** Slack is a messaging platform for teams.

Yes, it can take the sender address from a new Gmail message and use Slack's Find User by Email lookup. The result decides whether the run posts to a channel or stops there. ### ### Will an email that has been shared to Slack be marked in Gmail? It can be. After posting to a channel, the agent uses Add Label To Email on that message, and Create Label can make the label first if it does not exist yet. ### ### What can start an automation from Slack? Any of Slack's 15 triggers in the catalog, including New Channel, New Channel (instant), New Channel Member and New File (instant). Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Gmail when something happens in Slack? Any of Gmail's 41 actions, including Create Label, Send Email, Create Email Draft and Send Draft. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Gmail to Slack? Yes. When something happens in Gmail, your agent can act in Slack too. This page covers both directions: Gmail's triggers and Slack's actions are listed here as well. ### ### Do I have to build a connector for Slack or Gmail? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use Slack and Gmail without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
