Overview

AI-generated overview

Local MCP server that converts Markdown into Slack mrkdwn, Teams HTML, Jira ADF JSON, or plain text for an assistant.

What you can do
  • Convert Markdown to Slack mrkdwn for Slack API or Slack MCP text fields
  • Convert Markdown to HTML with inline CSS for Teams paste or Graph html content
  • Convert Markdown to ADF JSON for Jira Cloud REST v3 rich-text fields
  • Strip Markdown down to plain text for any destination
  • Handle CommonMark and GitHub-Flavored Markdown input
When to use it
Use it when an assistant needs to reformat Markdown before pasting or sending it into Slack, Microsoft Teams, Jira Cloud, or a plain-text destination, and you want the conversion done locally rather than by the model.
Requirements
Runs as a local stdio process, typically launched with npx from the npm package @ysskrishna/markdown-convert-mcp, so Node.js and network access for the package download are needed. No authentication, environment variables, or headers are declared.
Before you install
It only converts text: it does not send Slack or Teams messages or create Jira issues, so any actual posting is done by another tool. Input over 200,000 characters returns a tool error, and Slack may truncate text around 40k characters. Whitespace-only input returns an empty string rather than an error.

Installation

In SourceWeft

  1. Open Markdown Convert MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

MCP setup

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project only):

json
{  "mcpServers": {    "markdown-convert": {      "command": "npx",      "args": ["-y", "@ysskrishna/markdown-convert-mcp"]    }  }}

Then open Cursor Settings → MCP and confirm markdown-convert is enabled.

With a global install, you can use "command": "markdown-convert-mcp" instead of npx.

Tools and next hops

Each tool accepts { "markdown": "<source>" } and returns converted text. Pick the tool that matches where the string will go next.
