Just launched crosspost-mcp v0.1.0

Shipped the first version of crosspost-mcp — an open-source MCP server that lets Claude post directly to Telegram and Discord.

The pattern I kept hitting: Claude drafts a perfect post, then I'm manually copy-pasting it into Telegram, then Discord, then anywhere else. AI handles 95% of the workflow but the actual sending is always manual.

v0.1.0 ships with:

- post_to_telegram via Bot API

- post_to_discord via webhook

- post_to_all running both in parallel with fault isolation

Built on FastMCP. Free APIs only, MIT licensed.

Tested end-to-end in Claude Desktop on Windows. Works in sandboxed Store version too despite a UI bug in Settings → Developer.

Next up: Mastodon, then Bluesky, then Reddit when I figure out their OAuth.

Open to feedback on architecture or feature requests.
