Koskamo

capx café MCP

An open-source MCP server that enables coding agents to draft, preview, schedule, and publish posts to X (Twitter). It ensures security by keeping the user's X token on the server-side vault, using a short-lived session handle for the agent, and enforcing a deterministic server-side guardrail called 'casserole' before any post is published.
