Mynahcast MCP Server

What it is

Mynahcast lets an agent draft and schedule posts in your brand voice for Bluesky, Mastodon, Telegram, Discord and other channels.

Every post goes through human approval before it is published, so the agent prepares the work and a person signs it off. It suits small teams that want AI help with social posting without fully automated publishing.

Connect

• Endpoint: https://api.mynahcast.xyz/mcp (Streamable HTTP)
• Authentication: an API key sent as Authorization: Bearer <key>

Claude Code:

claude mcp add mynahcast --transport http https://api.mynahcast.xyz/mcp

Other clients (mcpServers config):

{ "mcpServers": { "mynahcast": { "type": "http", "url": "https://api.mynahcast.xyz/mcp" } } }

Create the API key in the Mynahcast app under Agents & API, then add it as an Authorization: Bearer <key> header in your client.

Limits and notes

• Needs a Mynahcast account and API key.
• Posts are published only after a human approves them.
• The endpoint answered a standard MCP initialize request when checked on 2026-11-08 (it returned 401 and asks for authorization, as expected for a signed-in service).
