Overview

AI-generated overview

Kalen is a remote X (Twitter) assistant that researches your niche daily, scores AI-written posts, and publishes the ones you approve.

What you can do
  • Research a niche on X on a recurring daily basis
  • Score posts drafted by your AI
  • Publish posts that have been approved
  • No tool list is published, so the exact operations available to an assistant are not documented.
When to use it
Worth considering if you run an X account and want a recurring loop of niche research, draft scoring and approval-based publishing handled from your assistant rather than by hand.
Requirements
A remote MCP endpoint at kalen.si connected over streamable HTTP. OAuth authentication is required, so you need a Kalen account and must complete the OAuth sign-in flow. No environment variables or headers are declared.
Before you install
It publishes to a public X account, so review what gets approved before anything goes live. OAuth grants the server access to your Kalen account. Niche research and post content are handled by a third-party service, and no tool list or documentation is provided to confirm exactly what it can read or change.

Installation

In SourceWeft

  1. Open Kalen in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/si.kalen%2Fkalen/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

  "mcpServers": {
    "kalen": {
      "type": "http",
      "url": "https://kalen.si/mcp"

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

67% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
