Slack remote MCP connector tool
The Slack remote Model Context Protocol (MCP) connector in Optimizely Agent Platform lets Mark interact directly with your Slack workspace. Mark helps you find team conversations, share updates, and act on decisions without switching between applications.
Beta
The Slack remote (MCP) connector is in beta.
These tools let Mark search messages, files, users, and channels, send and draft formatted messages, read channel and thread history, manage canvases, and retrieve user profiles. Use them to bring team context into your agents and workflows so you can act on Slack decisions and updates directly.
The Slack remote MCP is managed by Slack. For details, see Slack MCP server in the Slack documentation.
First, an Agent Platform administrator must Connect the Slack remote MCP to Agent Platform. After connecting the MCP server, individual Agent Platform users and agent builders can log in to Slack to access their information from Agent Platform. Administrators only need to connect the Slack remote MCP once.
Connect the Slack remote MCP to Agent Platform
Note
The first person to connect a third-party service to Agent Platform should be an administrator of that service. Administrator access installs the complete set of tools, so Agent Platform adds every available tool. If a non-administrator connects the service first, Agent Platform installs only the tools that account can access.
Agent Platform administrators connect and grant access to Slack from Agent Platform. After granting access, administrators select which tools to enable in Agent Platform and optionally customize their display names.
Add Slack connection
As an Agent Platform administrator, complete the following steps:
- Go to Connectors in Agent Platform.
- (Optional) Enter Slack in the search bar to filter the connectors list.
- Click Connect on the Slack tile.
- Review and configure the Slack connector.
- Click Allow.
A confirmation message displays and you can close the pop-up window.
Configure Agent Platform tools
After adding the Slack connection, Mark prompts you to select which tools to enable and optionally customize their display names.
As an Agent Platform administrator, complete the following steps:
- Deselect any tools you do not want to add to Agent Platform.
- (Optional) Update any tool's display name.
- Click Finish.
The Slack tile displays Connect on the Connectors tab for Agent Platform users to authenticate with their personal accounts.
To update the available tools or names, see Update tools.
Authenticate with Slack
Each Agent Platform user and agent builder logs in to Slack individually to access their Slack data from Agent Platform. User-level authentication ensures you access only the data your Slack account is authorized to view.
Before you begin, confirm that an Agent Platform administrator has connected the Slack remote MCP to Agent Platform. Until an administrator connects it, the Slack tile displays Contact admin instead of Connect and you cannot select it.
To authenticate, complete the following steps in Agent Platform:
- Go to Connectors.
- (Optional) Enter Slack in the search bar to filter the connectors list.
- Click Connect on the Slack tile.
- Log in to Slack.
After you connect to Slack, the Slack connector tools your administrator added become available in Mark chat, specialized agents, and workflows.
Slack connector tools
The Slack connector tools are available in Agent Platform after an administrator connects the remote MCP and you log in to Slack. The available tools depend on which tools your administrator enabled. For a full list of available tools and actions, see Slack MCP server in the Slack documentation.
Update tools
To rename, add, or remove tools, an Agent Platform administrator must delete the Slack tools registry and re-add it. To do so, complete the following steps:
- Follow the steps in Delete a tool registry.
