## About

A hosted toolset for agents on a Cloudflare Worker. Free tools reduce LLM context size: URL to Markdown, JSON trimming, log compression, token estimation, page outlines and a quick website check. Paid tools cover site audits, page metadata, summarizing, translation, image generation, screenshots, text to speech, embeddings, reranking, LLM chat, FX rates, crypto prices and Base and Solana address lookups.

It runs as a remote streamable-HTTP endpoint. No sign-in or API key is needed. Free tools have per-IP hourly limits. Paid tools cost a fixed USDC amount per call on Base, paid with x402; failed calls are not charged.

## What it can do

- Convert a public web page to compact Markdown
- Trim large JSON and compress logs to save tokens
- Estimate token counts and outline pages
- Audit websites for broken links, meta tags and security headers
- Summarize, translate, and screenshot web pages (paid)
- Look up Base wallets, tokens, transactions and gas (paid)
- Generate images, speech, embeddings and rerank documents (paid)

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http quickbuild-agent-tools https://quickbuild.quynguyenbac.workers.dev/mcp
```

2. Start Claude Code and type `/mcp`. **quickbuild-agent-tools** should show as connected.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **QuickBuild Agent Tools** and paste this URL:

```url
https://quickbuild.quynguyenbac.workers.dev/mcp
```

3. Click **Add**. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=QuickBuild%20Agent%20Tools&connectorUrl=https%3A%2F%2Fquickbuild.quynguyenbac.workers.dev%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://quickbuild.quynguyenbac.workers.dev/mcp` and click **Add**.

3. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://quickbuild.quynguyenbac.workers.dev/mcp` as the server URL, then for authentication choose **No authentication**.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=quickbuild-agent-tools&config=eyJ1cmwiOiJodHRwczovL3F1aWNrYnVpbGQucXV5bmd1eWVuYmFjLndvcmtlcnMuZGV2L21jcCJ9>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "quickbuild-agent-tools": {
      "url": "https://quickbuild.quynguyenbac.workers.dev/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=quickbuild-agent-tools&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fquickbuild.quynguyenbac.workers.dev%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"quickbuild-agent-tools","type":"http","url":"https://quickbuild.quynguyenbac.workers.dev/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "quickbuild-agent-tools": {
      "type": "http",
      "url": "https://quickbuild.quynguyenbac.workers.dev/mcp"
    }
  }
}
```

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "quickbuild-agent-tools": {
      "serverUrl": "https://quickbuild.quynguyenbac.workers.dev/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add quickbuild-agent-tools --url https://quickbuild.quynguyenbac.workers.dev/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.quickbuild-agent-tools]
url = "https://quickbuild.quynguyenbac.workers.dev/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http quickbuild-agent-tools https://quickbuild.quynguyenbac.workers.dev/mcp
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "quickbuild-agent-tools": {
      "type": "http",
      "url": "https://quickbuild.quynguyenbac.workers.dev/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://quickbuild.quynguyenbac.workers.dev/mcp`.
