Document

name: Messages & team chat on Mac (Local MCP) description: Use when the user wants to read or search iMessage, Microsoft Teams, Slack, WhatsApp or Signal on their Mac — things cloud connectors can't reach. Powered by Local MCP, local-only.

Messages & team chat via Local MCP

Local MCP reads the user's local message stores on their Mac — iMessage (Messages.app), Microsoft Teams, Slack, WhatsApp, Signal — which cloud connectors physically cannot access.

Core tools

  • iMessage: list_message_chats, read_messages, search_messages.
  • Teams: teams_list_chats / teams_list_channels / teams_read_chat_messages / teams_read_channel_messages.
  • Slack: slack_list_channels / slack_read_channel_messages / slack_search_messages.
  • WhatsApp / Signal: whatsapp_* / signal_* readers.
  • Sending: send_message (iMessage) and teams_send_message preview before sending — never send silently.

Good practice

  • Reading is local and fast; summarize conversations rather than dumping every line.
  • For "did X text me about Y", use search_messages.
  • Teams/Slack/WhatsApp/Signal require the respective app to be set up on the Mac; if a tool says it's not connected/synced, relay that setup step to the user.
  • Any send is preview-first — show the recipient + text, confirm, then send.

Trustgrade B

  • passBody integrity

    Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.

  • passType matchnot applicable to this artifact type

    Whether the artifact is really the kind of thing its metadata claims it is.

  • passFreshness

    How long since the source repository was last pushed to.

  • passPrompt injection

    Scans the artifact's own text for instructions aimed at your agent rather than at you.

  • warnLicenseno SPDX license detected

    Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

  • Aevery check passed
  • Bone warning
  • Ctwo warnings
  • Dprompt injection or body integrity failed, or three warnings
  • Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
