Overview

AI-generated overview

Remote MCP server that renders Markdown into a complete styled HTML document with light, dark or GitHub CSS themes, paid per call.

What you can do
Render Markdown text into a full, display-ready HTML page with embedded CSS, choosing a light, dark or GitHub theme (default GitHub). Return the HTML in JSON along with the theme and input/output lengths. Produce embeddable content blocks, documentation pages or email-ready HTML from Markdown.
When to use it
Useful when an assistant needs to turn Markdown into a styled, self-contained HTML document for previews, documentation pages or embeddable blocks, and a small per-call payment is acceptable. Not intended for plain HTML conversion without CSS or for PDF generation.
Requirements
A remote MCP endpoint added by URL to the client configuration; no API key or signup. Each render call is billed at $0.005 in USDC on Base L2 through the x402 protocol, so an x402-aware client and a funded wallet are needed to complete the payment challenge.
Before you install
Every render call costs money ($0.005 in USDC on Base L2) and requires signing a payment with a wallet; the README names Coinbase CDP and PayAI as facilitators and mentions an ATXP OAuth route. Markdown content is sent to a third-party service. No API key is used, so access control rests on the wallet.

Installation

In SourceWeft

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

Web executable via SSE. 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/io.github.Br0ski777%2Fmarkdown-renderer/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.

Markdown Renderer API

[MCP Server] [x402] [License: MIT]

Render Markdown to styled HTML with CSS themes -- light, dark, GitHub. Ready-to-embed HTML documents. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "markdown-renderer": {      "url": "https://markdown-renderer.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://markdown-renderer.api.klymax402.com/api/render" \  -H "Content-Type: application/json" \  -d '{"markdown":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

50% 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.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
