What is the primary purpose of the Slack MCP Server skill?

It is used to build standardized MCP servers that allow AI agents to perform complex actions in Slack, such as creating canvases or posting rich content, rather than just sending simple messages.

Does this skill support Slack Canvases?

Yes, it includes specific tools and patterns for creating and updating Slack canvases using markdown or document JSON formats.

Which programming language is used for implementation?

The skill provides implementation patterns and a DSL based on Ruby, utilizing the Slack Web Client library for API interactions.

How are Slack API credentials managed?

It uses a standardized configuration injection pattern to handle credentials like slack_token and team_id securely within the server setup.

Can I return interactive elements to Slack?

Yes, the architecture supports returning rich resources like Block Kit components, allowing agents to provide high-fidelity UI elements to Slack users.
