What you can do with Slack

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Slack API rate limits

50 requests per minute

Slack uses tiered rate limiting: Tier 1 (1/min), Tier 2 (20/min), Tier 3 (50/min), Tier 4 (100/min). This value represents Tier 3 as a general default.

These are the limits Slack documents, not ones LiveContext measured. They can change and often depend on your plan, so check the Slack documentation for current values.

Use Slack from Claude Code, Cursor or Codex

Connect Slack in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Slack operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Set up the MCP server step by step

How to connect Slack
