installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability

Install (Claude Code):

claude mcp add slack-mcp-server -- npx -y slack-mcp-server

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
