Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 42 stories with headroom
What would move Microsoft Teams’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Agenticness — how well agents can access and operate the productPlug MCP servers into this product so it can use their tools
nonemoves agent-readyimpact 45
Missing: any documentation of MCP server connection, tool registration via MCP, or first-party MCP client support in Teams agents.
Agenticness — how well agents can access and operate the productConnect an agent via an official MCP server
nonemoves agent-readyimpact 45
The evidence pack covers Teams' bot/agent SDK, Graph API, webhooks, and Agents Toolkit CLI, but nowhere mentions an official MCP (Model Context Protocol) server or endpoint that would let external AI agents connect to Teams.
Search knowledge — stories about search knowledge in this arenaSearch the full message history with filters like sender, channel, and date
nonemoves PA Scoreimpact 30
The evidence pack contains no vendor documentation of an admin-facing search feature with sender/channel/date filters — only generic Export APIs for compliance extraction (ms-teams-docs-13,14), which do not describe search/filter UI.
Workflow automation — stories about workflow automation in this arenaBuild no-code workflows triggered by events, schedules, or form submissions inside the chat tool
nonemoves PA Scoreimpact 30
Evidence pack covers developer-oriented bots, connectors, webhooks, and the Agents Toolkit CLI, all of which require coding/deployment rather than a no-code, admin-facing workflow builder triggered by events/schedules/forms; there is no mention of a no-code automation surface (e.g., Power Automate/Workflows app) inside Teams chat.
Openness — open source, data portability, and self-hosting storiesSelf-host the core product
nonemoves PA Scoreimpact 30
Microsoft Teams is a proprietary SaaS cloud service with no evidence of a self-hostable core product; all evidence describes cloud-hosted collaboration, extensibility via bots/tabs/connectors, and Azure-hosted app deployment, not self-hosting the Teams service itself.
Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models
nonemoves PA Scoreimpact 30
No evidence in the pack addresses opt-out or controls for AI/model-training use of Teams data; docs cover bots, agents, webhooks, and Copilot features but nothing about training-data exclusion or privacy controls for AI training.
Agenticness — how well agents can access and operate the productPoint an agent at llms.txt or agent-oriented docs
nonemoves agent-readyimpact 30
Probes explicitly show no llms.txt (404), no markdown-accessible docs endpoint, and no OpenAPI spec at Microsoft Learn — there's no agent-oriented documentation surface for an AI agent to point at.
Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent
nonemoves agent-readyimpact 30
While Teams' Graph API and Agents Toolkit are documented for building agents/apps, none of the evidence describes issuing scoped or least-privilege API credentials specifically for an agent (e.g., granular OAuth scopes, permission consent flows tied to agent identity).
