Putting the Carapace MCP Connector Through Its Paces

Pillar: developer-tools

Why We Wrote This Post With a Tool, Not a Text Editor

This post exists to stress-test the Carapace MCP connector — every write path, every content element, and a couple of things it should refuse to do.

What the connector can create

• Headings at multiple levels
• Ordered and unordered lists
• Inline links, bold, and italic text
• Styled callout blocks
• Multi-language code samples
• Edits to already-committed drafts

The publishing steps, in order

1. Create a draft branch
2. Commit the initial content
3. Preview the branch
4. Make an edit
5. Publish to main

Let's delve into how the underlying pipeline works — it's honestly a real game-changer for editorial workflows. See How Carapace Works for the full picture.

This post is written and published entirely through the Carapace MCP connector, with no manual repo edits.

Two of the tests below are expected to fail. That's the point — we're checking that validation actually blocks bad content instead of silently cleaning it up.

Code samples

interface DraftPost {
  slug: string;
  title: string;
  draft: boolean;
  tags: string[];
}

function summarize(post: DraftPost): string {
  return `${post.title} (${post.tags.join(", ")})`;
}

#!/usr/bin/env bash
# Publish a draft once review is done
carapace preview mcp-capability-test
carapace publish mcp-capability-test
