Tools for any AI
These are the tools TOLLkit Wallet’s AI reaches for. Any other AI can use them too: paid per call in USDC, free calls every day, and a failed call costs nothing.
- paid tools
- 34
- free tools
- 7
- the lowest price a call
- $0.001
- accounts or API keys needed
- None
Tools marked 3 free/day give three free calls a day once your AI is connected through MCP, no wallet needed.
Checking these prices against the service…
Connect your AI
One web address. Nothing to install, no account, no API key. Pick your app for the three steps.
https://api.tollkit.dev/mcp
Connect TOLLkit Wallet and your AI pays from it, inside the tool-spend cap you set. Without a wallet it just shows the price, and the free tools work straight away.
Claude, web and desktop app
- Open Customize, then Connectors.
- Click +, then Add custom connector.
- Paste this address, leave Advanced settings empty, and click Add:
https://api.tollkit.dev/mcp
Turn it on in a chat with the + button, bottom left, then Connectors. Free plans can add one connector like this. On Team or Enterprise, an owner adds it under Organization settings → Connectors first.
ChatGPT, Business, Enterprise and Edu
- Open Settings → Apps → Advanced settings and turn on Developer mode. On Enterprise and Edu an admin has to allow it first.
- Create a new app and give it this address as its MCP server:
https://api.tollkit.dev/mcp - Your workspace admin may need to approve it before it shows in chats.
Custom connectors in ChatGPT need a Business, Enterprise or Edu plan and work on the web. Pro can connect read-only. OpenAI changes these menus often; their guide is the current word.
Cursor, in one click
Needs Cursor installed on this computer. Or add it by hand to ~/.cursor/mcp.json:
{
"mcpServers": {
"tollkit": { "url": "https://api.tollkit.dev/mcp" }
}
}VS Code, with GitHub Copilot
- In your project, open or create
.vscode/mcp.json. - Put this in it, or add the
tollkitentry to what’s there:{ "servers": { "tollkit": { "type": "http", "url": "https://api.tollkit.dev/mcp" } } }
VS Code uses "servers", not "mcpServers", the usual reason a copied snippet silently doesn’t load. Prefer menus? Run MCP: Add Server from the Command Palette and give it the address.
Claude Code, in the terminal
Paste into your terminal:
claude mcp add --transport http --scope user tollkit https://api.tollkit.dev/mcp--scope user makes it available in every project, not just this folder.
Codex, OpenAI’s terminal agent
Paste into your terminal:
codex mcp add tollkit --url https://api.tollkit.dev/mcpGemini CLI, in the terminal
Paste into your terminal:
gemini mcp add --transport http tollkit https://api.tollkit.dev/mcpCheck it worked. Ask it: “Use TOLLkit’s try_it_free tool.” It’s free and returns a real result. Free tools work straight away; paid ones need an agent with its own wallet. Set one up.

For builders
The same tools as agent skills, a Claude Code plugin, AgentCash entries, OpenAPI files and llms.txt.
Skills and plugin
The same tools, packaged so an agent knows when to use them. Source: github.com/UltraStarz/tollkit-skills.
Any agent that supports skills (Claude Code, Cursor, Codex and others):
npx skills add UltraStarz/tollkit-skillsClaude Code plugin (adds the skills and the MCP server). Run this:
/plugin marketplace add UltraStarz/tollkit-skillsthen this:
/plugin install tollkit@tollkitAgentCash, one line for each host: web, chain, data and extract.
npx agentcash@latest add https://web.tollkit.dev
npx agentcash@latest add https://chain.tollkit.dev
npx agentcash@latest add https://data.tollkit.dev
npx agentcash@latest add https://extract.tollkit.devMachine-readable
- llms.txtEvery tool, its URL, body and price
- OpenAPI: webweb.tollkit.dev
- OpenAPI: chainchain.tollkit.dev
- OpenAPI: datadata.tollkit.dev
- OpenAPI: extractextract.tollkit.dev
- OpenAPI: attestattest.tollkit.dev
- x402 manifestextract.tollkit.dev
OpenAPI comes one file per hostname. Each paid answer includes a receipt: request id, tool, price and payment transaction (request_id, tool, price_usdc, payment_tx). Every route on this page shows its host; an HTTP route given without one is on https://extract.tollkit.dev.
Selling a tool yourself
Weigh Station checks any x402 endpoint for free. Monitoring is paid by the seller, never by agents, so the checks stay free and neutral.
| Tool | HTTP route and term | Price |
|---|---|---|
| Endpoint monitoringYour endpoint checked every 15 minutes for 30 days, with a signed webhook when it goes down, changes price or changes wallet. | POST extract.tollkit.dev/weigh/subscribe30 days | $5.00 |
