Verified · today

Read and write Slack with session tokens — no OAuth, no bot, no admin approval.

Install

claude mcp add slack-mcp -- npx -y @aaronsb/[email protected]

Requires: SLACK_MCP_XOXC_TOKEN, SLACK_MCP_XOXD_TOKEN

Our take

Connects MCP clients to Slack for reading and sending messages using user session tokens instead of OAuth or bot installs. It is mainly for individuals or small teams that need direct Slack access without workspace admin involvement. The approach is practical but higher-risk from a security and account-policy standpoint, and the very low star/download footprint suggests an early, lightly validated project.
