Pulling everything programmatically

// Node 20+, ES modules
const res = await fetch('https://enterprisedna.co/directories/api/index.json');
const { meta, entries } = await res.json();

// Filter to agents that use a specific MCP server
const agentsUsingSupabaseMcp = entries.filter(
  e => e.directory === 'agents' && e.relations.uses?.includes('mcp-supabase')
);

// Or fetch one entry fully
const claude = await fetch(
  'https://enterprisedna.co/directories/api/agents/claude-code.json'
).then(r => r.json());
