Slack MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Slack and the rest of your systems. It gives your agent 334 Slack actions (122 reads, 159 writes and 53 that wait for a confirmation) and holds the Slack credential itself, so the agent never does. It paces Slack's limits and records every call.
100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Set up
Connect Slack in three steps.
- 01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.
https://connect.actionlake.com/mcp - 02
Connect Slack.
Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

Make the first call. Check before a write.
Ask in plain words; Claude picks the action. Before anything changes,
checkvalidates the call and prices it, for free.do { action: "slack.team_info" }# info — team · read · 1 upstream callcheck { action: "slack.usergroups_create", input: { … } }# free: inputs, permissions, cost and confirmations, nothing sent

Slack's own MCP server
Slack's MCP server, or actionlake?
Slack runs a remote MCP server at mcp.slack.com. A client must be backed by a registered Slack app, published in Slack's directory or internal to your workspace, and signs in with OAuth.
Use Slack's server when one person wants to work in Slack from their own AI client. Use actionlake when you also want Slack behind the same endpoint as your other systems: a key per agent with allowed actions and a spending cap, a named person's approval before destructive actions, a sealed record of every call, and one ask across Slack and another system.
Source: Slack's documentation, checked 22 October 2026.
Top actions
The Slack API, shaped for agents.
The ids your agent types, what each does, and the one name it shares with other systems. 168 of Slack's 175 action names are shared with at least one other connector, so an agent learns them once.
| Action | What it does | Effect | Same name in |
|---|---|---|---|
slack.users_listList — users | Calls the Slack Web API method `users.list`. | read | identity.user.list474 connectors |

The plan store
Ready-made plans for Slack.
9 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.
Review and approve pending app install requests
Use it when Admins need to work through the queue of Slack app install requests waiting for a decision.
A person decides
Approve number of app requests pending Slack app install requests for team team id, with the scopes each app asked for.
Archive channels with no recent activity
Use it when Someone asks to clean up dormant Slack channels that nobody has posted in for months.
A person decides
Archive number of channels Slack channels that have had no messages since inactive before.
Post a weekly activity report for key channels
Use it when Someone wants a recurring digest of how busy a set of Slack channels has been.
Export a Slack list and share the download
Use it when Someone asks for the contents of a Slack list as a file they can download.
Search for a topic and escalate what turns up
Use it when Someone needs to know where a phrase, incident name or customer is being discussed in Slack.
Create a project channel and set it up
Use it when A new project or workstream is starting and needs its Slack home set up in one go.
Update a user group's members and channels
Use it when A team roster changed and the matching Slack user group needs to match it again.
A person decides
Replace the members of user group usergroup (currently users) and add it to channel ids.
Offboard a departing person from Slack
Use it when An employee is leaving and their Slack access needs to be wound down in one pass.
A person decides
Offboard real name (email) from Slack: clear sessions, force sign-out and set expiry expiration ts.
Pull an app's access after a security review
Use it when A security review decided a Slack app must lose its access to the org.
A person decides
Uninstall app app id from team team id and strip all of its permissions. This breaks anything relying on it.

Destructive actions wait for a yes.
53 Slack actions are destructive. The first 10:
- Delete — chat
slack.chat_delete - Delete scheduled message — chat
slack.chat_deletescheduledmessage - Delete — files
slack.files_delete - Remove — files remote
slack.files_remote_remove - Delete photo — users
slack.users_deletephoto - Uninstall — apps
slack.apps_uninstall - Remove — admin users
slack.admin_users_remove - Close — conversations
slack.conversations_close - Delete — admin conversations
slack.admin_conversations_delete - Bulk delete — admin conversations
slack.admin_conversations_bulkdelete
A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.
Delete — chat?
intent: the user asked me to delete — chat
account { op: "keys.create", name: "slack-agent", allowed_actions: ["slack.*"], cap_calls: 2000, confirm_policy: "human_for_writes", approval_rules: [ { match: "slack.chat_delete", approver: "[email protected]" }, { match: "slack.chat_deletescheduledmessage", approver: "[email protected]" }, { match: "slack.files_delete", approver: "[email protected]" } ]}Cost
What Slack costs on actionlake.
Every Slack action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Slack refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions
The Slack MCP server, answered.
Is there a Slack MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 334 Slack actions across administration, chat, files and apps, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Slack.
Does Slack have its own MCP server?
Slack runs a remote MCP server at mcp.slack.com. A client must be backed by a registered Slack app, published in Slack's directory or internal to your workspace, and signs in with OAuth. (Slack's documentation, checked 22 October 2026.) Use Slack's server when one person wants to work in Slack from their own AI client. Use actionlake when you also want Slack behind the same endpoint as your other systems: a key per agent with allowed actions and a spending cap, a named person's approval before destructive actions, a sealed record of every call, and one ask across Slack and another system.
What do I need to connect Slack?
Slack bot token (xoxb-…). The free call account { op: "connections.requirements", service: "slack" } lists exactly what to paste.
Can an AI agent delete or change things in Slack?
Only if its key allows it, and only with an explicit confirmation. 53 Slack actions are destructive, including delete — chat, delete scheduled message — chat and delete — files. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.
Will an AI agent use up my Slack API limit?
actionlake paces every call to the limits in the Slack service file: 20 calls a minute per connection. Repeated reads are answered from cache (122 Slack actions can be), which never reaches Slack.
What does a Slack action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (334 Slack actions page). Cache hits, searches, dry runs and calls Slack refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.
Which Slack API does it cover?
The Slack API 1 at slack.com/api. It is built from Slack's documentation as read on 15 September 2026. 334 actions in 16 areas, each one in the signed service file (version 2.0.0).
Does actionlake keep my Slack data, and where?
actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Slack credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.
Which AI clients can use it?
Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
