About capx café
capx café is an MCP server published by the GitHub account vb-tyagi. Agent-native X (Twitter) posting as one MCP server; every post clears a server-side guardrail.
It runs on your own machine: your AI client starts it from the npm package capx-cafe at version 0.1.3.
It asks for no keys or passwords.
It also needs CAPX_CHOKEPOINT_URL and CAPX_EMAIL set before it starts.
Version 0.1.3 was published on 3 September 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
