Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http tools https://toolsthatdontupload.com/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "tools": {
      "url": "https://toolsthatdontupload.com/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "tools": {
      "type": "http",
      "url": "https://toolsthatdontupload.com/mcp",
      "headers": {

Common questions

Is Tools That Don't Upload safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.0) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Tools That Don't Upload

MCP server and REST API for data, text, code, PDF and web tasks. Requests are processed in memory and not stored.

MCP endpoint (Streamable HTTP): https://toolsthatdontupload.com/mcp (v1.5.0)
MCP tools: search_tools, run_tool, list_categories (they search and run the REST catalog)
REST API: https://toolsthatdontupload.com/openapi.json (every endpoint, generated; every documented example is tested)
Network tools (fetch URL, DNS, WHOIS, SSL) need an X-API-Key header. Free key: https://toolsthatdontupload.com/api-keys/

Korean tools

Romanization, amounts in Korean words (일금 ...원정), particles (조사), initial consonants (초성), business-number checksum, personal-data masking. Document generation: 견적서 / 거래명세서 (XLSX), 차용증 / 표준근로계약서 (DOCX).

Egress receipts

Every REST response has an X-Egress header and every MCP result has _meta["com.toolsthatdontupload/egress"] listing external hosts contacted (none for most tools).

Files through MCP

PDF tools accept file_base64 / files_base64 (max 10 MB) and return file_base64.

Quick start

Claude Code:

claude mcp add --transport http tools-that-dont-upload https://toolsthatdontupload.com/mcp

Cursor / other clients:

{"mcpServers":{"tools-that-dont-upload":{"url":"https://toolsthatdontupload.com/mcp"}}}

Limits

Anonymous: compute tools under fair use; file 20 calls/day; AI 10 calls/day per IP.
Free key: 1,000 credits/month. Paid plans: coming soon.

Privacy

Yellow = edge memory only. Orange = our edge fetches the URL you give. Blue = Cloudflare Workers AI. Details: https://toolsthatdontupload.com/privacy/

Note: this repository is a documentation snapshot, not the full deployed source.

Repository layout

workers/ — source of the production Cloudflare Workers that this repo deploys: tools-mcp-server (the MCP server at /mcp), tools-hub-ratelimit (gateway for network, file and AI tools), tools-hub-keys, tools-hub-kr (Korean tools), tools-hub-docs (Korean documents). Every folder in workers/ is deployed by GitHub Actions (.github/workflows/deploy.yml → scripts/deploy.mjs) with build provenance attestations; the live commit is shown at https://toolsthatdontupload.com/mcp and https://toolsthatdontupload.com/transparency/.
tests/ — black-box regression tests that run against a deployed MCP endpoint (node tests/search-regression.mjs [MCP_URL]).
plugin/ — Claude plugin (hosted connector + offline local server + 2 skills).
local/ — offline MCP bundle source (.mcpb, release local-v1.0.0).
server.json — MCP Registry metadata.
SECURITY.md — how outbound requests are restricted, known limits, and how to report issues.

Development notes

The MCP server code that actually runs is workers/tools-mcp-server/worker.mjs. The old root mcp-server.js was an outdated copy and was removed on 2026-10-12 (still in git history).
Not everything is in this repo: the static site, the ~25 compute-tool Workers and the network-tool Workers are deployed separately. The MCP server reaches them through Cloudflare service bindings.
Pushing to workers/, scripts/deploy.mjs or the workflow file deploys to production. Test changes on a separate workers.dev script first.
