Outbound messages, SMS, email deliverability, consent, unsubscribe behavior, private chats, and customer-facing replies need approval, throttling, and audit logs. MCP servers inherit the connected account's scopes and may send prompts or data to third-party services; configure read-only or narrow scopes when available. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging.","pricingSummary":"Public seat-based pricing with free and paid plans.","authModel":"OAuth apps, user tokens for MCP, bot tokens, signing secrets, and webhooks.","accountCreation":"Self-serve workspace signup and app creation.","browserSupport":"Admin and app setup often requires browser flows.","cliPackage":null,"apiBaseUrl":"https://slack.com/api","mcpServer":"https://mcp.slack.com/mcp","agentScore":67,"agentTier":"Usable","scoreBreakdown":{"score":67,"tier":"Usable","summary":"Usable: 67/100.
