For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/builtwith-mcp-960ca192aa
GET https://www.mcpbundles.com/api/directory/v1/servers/builtwith-mcp-960ca192aa?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/builtwith-mcp-960ca192aa/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/builtwith-mcp-960ca192aa/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.
Builtwith is an MCP server at api.builtwith.com. MCPBundles discovered 48 tools on the live endpoint.
How do I connect Builtwith to my AI agent?
Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.

Operate Builtwith?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Vat Api — VAT API JSON lookup for VAT, GST, CNPJ, ABN, and other publicly displayed company registration numbers associated with websites. Accepts 1–16 comma-separated domains.

Returned identifiers are found on public websites and are not verified or validated by BuiltWith.

Usage Api — Usage API JSON lookup for current credit balance (used, purchased, remaining). Uses no API credits.
Mcp List Api — Search and browse remote MCP servers in the BuiltWith MCP registry (v2). Requires a BuiltWith API key supplied as a bearer token. Provide search, category, or both. Returns up to 100 results per page as a JSON array of {Domain, Category, Description, Endpoints: [{Endpoint, AuthRequired, Tools: [{Name, Description}]}], first_detected, last_detected}, and preserves the complete API response including any fields added in the future. Uses no API credits.
Mcp List Categories — List valid BuiltWith MCP registry category slugs, labels, and entry counts (v2). This public endpoint requires no API key and uses no API credits.
