| Safety flags | Write tools exist (send message, schedule/draft messages, create conversations, reactions, canvas edits, file upload, lists). No read-only mode was found in the docs read, but write tools need separate scopes (e.g. chat:write), so scopes can be withheld, and Claude can set per-tool permissions. | None |

Slack verdict
As of October 2026, Slack publishes an official remote MCP server at mcp.slack.com/mcp, and Anthropic lists it as a verified Claude connector made by Slack. It uses OAuth with per-tool user scopes, and workspace admins must approve the client. It can send messages and edit canvases, so review permissions before enabling.
Setup, tools and safety check for Slack →Discord verdict
As of October 2026, no official Discord MCP server that can act on servers, channels or messages is verified. Discord's developer docs do offer an official MCP server at docs.discord.com/mcp for searching documentation. Community servers such as SaseQ/discord-mcp use a Discord bot token to read and send messages and manage channels.
