MarkdownPointer

Vibe writing for Markdown. Point at anything, tell AI to fix it.

MarkdownPointer renders your Markdown and lets you click any element - headings, code blocks, table cells, Mermaid diagram nodes, KaTeX math - to copy a filepath:line reference. Paste it into your AI prompt, and the AI knows exactly where to look.

To change a node's color:

Click the node, paste the reference into your prompt, and ask the AI — done.

Color this node orange [c:\docs\architecture.md:6] mermaid node: mdp.exe

Install

In a PowerShell 7 console:

Install-Module MarkdownPointer

Quick Start

mdp .\README.md    # Open a file
mdp .\docs\*.md    # Open multiple files
mdp                # Just launch the viewer

MCP Server Setup

Connect MarkdownPointer to Claude so your AI can open and navigate documents directly.

Run these in PowerShell 7:

Register-MdpToClaudeCode       # Claude Code
Register-MdpToClaudeDesktop    # Claude Desktop

Other MCP clients: Add the output of Get-MarkdownPointerMCPPath -Escape as the command in your MCP client's configuration file.

Troubleshooting: If the MCP client fails to connect to the server, .NET 10 Desktop Runtime may not be installed. .NET 10 is not included with Windows — install it and try again.

Then just ask Claude:

"open README.md in mdp"
"show the report in mdp and scroll to line 50"
"export report.md to docx"
"export slides.md to pptx"
"import presentation.pptx to markdown"
"show me slide 3 of slides.md"
