🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for Slack MCP, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology. Are you the vendor? Factual corrections are free.
Overview
The Slack connector lets agents read and post messages across channels, search history, and interact with a workspace's people and content. It authenticates with workspace tokens that can span many channels. Message content from a workspace can carry prompt-injection payloads, and posting rights let an agent broadcast to teammates, so token scoping and confirmation on posts matter.
