# 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.

Prices shown are the ones the service charges. The live list is at [extract.tollkit.dev/health](https://extract.tollkit.dev/health).

[Connect your AI](#connect) [See every tool and price](#web)

## 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

1.  Open **Customize**, then **Connectors**.
2.  Click **+**, then **Add custom connector**.
3.  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

1.  Open **Settings → Apps → Advanced settings** and turn on **Developer mode**. On Enterprise and Edu an admin has to allow it first.
2.  Create a new app and give it this address as its MCP server:
    
    ```
    https://api.tollkit.dev/mcp
    ```
    
3.  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](https://help.openai.com/en/articles/12584461-developer-mode-and-mcp-apps-in-chatgpt) is the current word.

### Cursor, in one click

[Add to Cursor](/tools/cursor:/anysphere.cursor-deeplink/mcp/install?name=tollkit&config=eyJ1cmwiOiJodHRwczovL2FwaS50b2xsa2l0LmRldi9tY3AifQ%3D%3D)

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

1.  In your project, open or create `.vscode/mcp.json`.
2.  Put this in it, or add the `tollkit` entry 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/mcp
```

### Gemini CLI, in the terminal

Paste into your terminal:

```
gemini mcp add --transport http tollkit https://api.tollkit.dev/mcp
```

**Check 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](/wallet/#get).

## How paying works

1.  ### Ask
    
    Your AI calls a tool. Without a payment it gets the price back, not an error.
    
2.  ### Pay
    
    It signs a USDC payment on Base or Solana from the wallet it was given. No ETH or SOL needed for fees.
    
3.  ### Get the result
    
    The call runs and settles. If it fails, nothing is charged. Each answer comes with a receipt, and a retry with the same `Idempotency-Key` isn’t charged twice: the same key and body within 10 minutes returns the same answer.

## 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](https://github.com/UltraStarz/tollkit-skills).

**Any agent that supports skills** (Claude Code, Cursor, Codex and others):

```
npx skills add UltraStarz/tollkit-skills
```

**Claude Code plugin** (adds the skills and the MCP server). Run this:

```
/plugin marketplace add UltraStarz/tollkit-skills
```

then this:

```
/plugin install tollkit@tollkit
```

**AgentCash**, 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.dev
```

### Machine-readable

-   [llms.txt](https://api.tollkit.dev/llms.txt)Every tool, its URL, body and price
-   [OpenAPI: web](https://web.tollkit.dev/openapi.json)web.tollkit.dev
-   [OpenAPI: chain](https://chain.tollkit.dev/openapi.json)chain.tollkit.dev
-   [OpenAPI: data](https://data.tollkit.dev/openapi.json)data.tollkit.dev
-   [OpenAPI: extract](https://extract.tollkit.dev/openapi.json)extract.tollkit.dev
-   [OpenAPI: attest](https://attest.tollkit.dev/openapi.json)attest.tollkit.dev
-   [x402 manifest](https://extract.tollkit.dev/.well-known/x402)extract.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](/weigh-station/) checks any x402 endpoint for free. Monitoring is paid by the seller, never by agents, so the checks stay free and neutral.

Endpoint monitoring for sellers: route, term and price
| 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/subscribe`30 days | $5.00 |
