Security

Security, procurement, and operational review for Slack MCP Cloud.

This page is the buyer-facing trust surface for token handling, storage boundaries, analytics disclosure, support envelope, and rollout review. It exists to answer practical procurement questions without sending managed buyers into GitHub.

Security summary

  • HTTPS/TLS on all hosted traffic
  • Ephemeral token handling by default
  • Persistent storage only with explicit consent
  • AES-256-GCM encryption at rest for stored credentials
  • No Slack message retention as product analytics

Token and storage model

  • Ephemeral mode: default path, no durable credential write required
  • Persistent mode: opt-in only when the operator explicitly consents
  • Bearer keys: tenant-scoped API keys gate MCP access
  • Account surface: reconnect and disconnect stay available through /account

Data boundary

  • Slack requests proxy through the hosted worker and return directly to the MCP client
  • Slack messages, files, and channel history are not stored as analytics payloads
  • Usage metrics track request counts and plan state only
  • Full data-handling detail stays in privacy

Website measurement

  • Cloudflare Web Analytics covers the hosted website only
  • First-party funnel events cover pricing, deployment, checkout, setup, and account actions
  • Neither layer changes Slack token handling or Slack message retention
  • Use this page and privacy for procurement review, not GitHub issues

Support and incident envelope

  • Solo: managed endpoint plus standard hosted support routing
  • Team: adds shared workflow outcomes and higher usage ceilings
  • Turnkey Team Launch: rollout and buyer review envelope
  • Managed Reliability: ongoing operational support boundary when Slack context is business-critical

Procurement questions this page answers

  • Where tokens live and how they are protected
  • What data is and is not retained
  • Which routes are public versus authenticated
  • How support, rollout, and reliability expectations are scoped

Deployment review scope

Use deployment review when the team needs buyer review, rollout sequencing, support-envelope clarification, or premium fit guidance. That keeps the commercial and operational conversation on the hosted surface.

When self-host is the better answer

If procurement or operations require full runtime ownership, local transport control, and direct token handling under your own environment, the OSS/self-host path remains available with 21 tools.
