How do I let an AI agent slack send message?

Connect Slack to CybrLink, then expose the `slack_send_message` tool to any MCP-capable agent (Claude, GPT, or a custom framework). The agent calls it with typed arguments; CybrLink injects the Slack credential server-side and runs one scoped API call. Send a message to a Slack channel using the user's connected Slack. Returns { ok, channel, ts }.

Does the AI model see my Slack credentials when using SLACK_SEND_MESSAGE?

No. CybrLink stores the credential in a token vault and injects it on the server for each call, so the model can take this action in Slack without the OAuth token or API key ever entering its context.

How to call it

Expose this tool to any MCP-capable agent (Claude, GPT, or your own) through CybrLink's MCP server. The agent calls slack_send_message with arguments matching the schema above.

CybrLink validates the input, injects the connected Slack credentials server-side, and runs a single scoped provider API call through the shared proxy — the same guarded path as the generic call_api tool. The raw secret never reaches the model, and the response is trimmed to just the fields the agent needs.

Write action — gate behind explicit user approval and write scope.
