The Challenge

Business Problem

API documentation is perpetually outdated. Developers change endpoints but forget to update docs. New team members struggle with incorrect examples.

The Approach

Solution Overview

Connect GitHub MCP Server with OpenAPI MCP Server and Mintlify to automatically generate docs from code, validate examples, and publish updates on every merge.

Step-by-Step

Implementation Steps

Extract API Schema

Parse OpenAPI specs or code annotations to extract endpoint definitions.

Generate Documentation

Create formatted documentation pages with descriptions, parameters, and examples.

Validate Examples

Test all code examples against the live API to ensure they work.

async function syncDocs() {
  const spec = await openapi.loadSpec({ url: `${API_URL}/openapi.json` });
  const endpoints = await openapi.listEndpoints();
  for (const endpoint of endpoints) {
    const doc = generateDocPage(endpoint);
    await mintlify.updatePage({ slug: endpoint.path, content: doc });
  }
  await mintlify.deploy();
}

Auto-Publish on Merge

Trigger documentation regeneration when API code merges to main.

Doc Generator

function generateDocPage(endpoint) {
  return `# ${endpoint.method.toUpperCase()} ${endpoint.path}\n\n${endpoint.description}\n\n## Parameters\n${formatParams(endpoint.parameters)}\n\n## Example\n\`\`\`bash\ncurl -X ${endpoint.method} ${API_URL}${endpoint.path}\n\`\`\``;
}
