Connect Slack. Slack opens its own sign-in. Sign in and allow ApexGenius.

Then ask Hermes Agent:

Show my connected Slack accounts. For the account I choose, discover the read-only channel-list tool and list up to five channel names. Do not read or send messages.

Written setup, step by stepShow

Before you start

  • A Slack account in each workspace and permission to authorize the app. Workspace admins may need to approve it.

1. Connect Slack to ApexGenius

  1. Open Slack in Connections. Sign in to ApexGenius, open Connections, and choose Slack.
  2. Choose the Slack user and workspace. Sign in with the intended Slack account. Check the workspace and requested access before you allow it.
    Slack's page titled Allow the ApexGenius app to access Slack, with a workspace picker on the left, the list of permissions on the right, and Cancel and Allow buttons.
    Connect opens Slack's own permission page. Pick the workspace, review what ApexGenius can view and do as you, then choose Allow.Open full-size image (opens in a new tab)
  3. Add your other accounts. Check the saved workspace and user. Choose Add connection and repeat for each account. Use a clear name for each connection. Reconnect signs in to the same user and workspace.
  4. Choose tools and AI access. Open Tools and Access for each connection. Start with Read only for your AI. Enable writes only when you need them. Enabled writes run when called.
  5. Try one read per account. Name the intended Slack connection in your request. Check that the result and Tool Activity show that account.

2. Connect ApexGenius to Hermes Agent

Use this server address when adding the connection:

https://server.autom8.pro/mcp
  1. Add ApexGenius as a remote MCP server in your Hermes Agent configuration using the hosted HTTP URL, then complete the authorization in your browser.
  2. When ApexGenius asks what this AI client may use, choose Read only for the first test, or Custom to limit it to the tools you need.
  3. Start a new conversation and select ApexGenius from the available tools before asking for live data.

3. Verify one safe read

Show my connected Slack accounts. For the account I choose, discover the read-only channel-list tool and list up to five channel names. Do not read or send messages.

Compare the selected workspace and user with Slack. Repeat for each connection. A successful read does not verify writes or access to another account.

What Hermes Agent can do in Slack

3 operations. Read looks things up and changes nothing. Write changes Slack and runs only when that tool is enabled.

Read2 operations

Looks things up. Changes nothing.
  • slack_search_toolsDiscover what the selected Slack account can do: Slack's official tools and the Slack Web API methods ApexGenius runs.
  • slack_call_read_toolRun a discovered operation only when it is classified read-only.

Write1 operation

Changes Slack. Runs only when enabled.
  • slack_call_toolRun an enabled Slack write for the selected user and workspace, such as sending, editing, pinning or managing a channel. Writes run when called.

You choose what Hermes Agent can use

When you approve Hermes Agent, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

Limits in Slack

  • · Each connection identifies both the Slack user and workspace. Two users in one workspace remain separate.
  • · Private channels and DMs follow the connected user’s Slack access. ApexGenius does not add access to other users’ private conversations.
  • · The read route refuses writes and anything not classified as a read. Enabled writes run when called.
  • · ApexGenius uses Slack's official tools and Slack's Web API. Admin methods need a Slack org admin on Enterprise Grid. Sign-in, token and app-management methods are not available.
  • · Disconnecting stops future calls. It does not undo a sent message or another completed change.

Try asking

One ApexGenius account covers every pair below. Connect an app once and each agent you allow can use it.

Questions people ask first

Can I connect several Slack accounts?

Each user and workspace can have its own connection. Add accounts within your connection allowance and name the account in your request.

Can it do everything my Slack account can do?

It reaches most of it. ApexGenius uses Slack's official tools plus Slack's Web API, so pins, bookmarks, reminders, user groups, channel management and message edits are included, within your Slack permissions and the access you approve. Admin methods need a Slack org admin on Enterprise Grid. Sign-in, token and app-management methods are left out.

Can my AI read private messages?

Only messages the connected Slack user can access, when Slack grants the needed permissions and the read tool is enabled.

What does setup require?

An eligible Slack app, workspace approval where required, and separate OAuth consent for each account. Slack permits official MCP access for internal apps and Marketplace-published apps.
