## About

Skavio Paid MCP offers two distinct payment paths. Four standalone blockchain payment-proof and DNS/TLS audit tools use native USDC via x402 (Base/Solana), not card-funded credits. Separately, authenticated tenant-bound processing relays handle OCR, invoices, PDF, audio and web jobs with prepaid Skavio credits, quotes and budget limits. Those company processing credits can be funded by a regular payment card or USDC. Processing requires a Skavio customer API key and the correct company identity; paid proof tools still require native USDC. The compatible technical MCP address is https://www.skavio.eu/mcp. Current docs: https://getskavio.com/agent-tools/ and https://getskavio.com/x402/.

## What it can do

- Verify native USDC payments on Base and Solana
- Match exact payment amount and recipient on-chain
- Create blockchain evidence PDFs (not tax invoices)
- Audit DNS and TLS certificates for public domains
- Run authenticated company OCR, invoice and PDF processing relays
- Transcribe audio using tenant-bound prepaid processing credits
- Quote processing jobs and apply credit budget limits
- Fund processing credits by card or USDC; proof tools stay x402 USDC-only

## Install

### Claude Code

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

```bash
claude mcp add --transport http skavio-usdc-payment-verification-proof https://www.skavio.eu/mcp
```

2. Start Claude Code and type `/mcp`. **skavio-usdc-payment-verification-proof** 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 **Skavio USDC Payment Verification & Proof** and paste this URL:

```url
https://www.skavio.eu/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=Skavio%20USDC%20Payment%20Verification%20%26%20Proof&connectorUrl=https%3A%2F%2Fwww.skavio.eu%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://www.skavio.eu/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://www.skavio.eu/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=skavio-usdc-payment-verification-proof&config=eyJ1cmwiOiJodHRwczovL3d3dy5za2F2aW8uZXUvbWNwIn0%3D>) (opens Cursor)

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

`mcp.json`:

```json
{
  "mcpServers": {
    "skavio-usdc-payment-verification-proof": {
      "url": "https://www.skavio.eu/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=skavio-usdc-payment-verification-proof&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fwww.skavio.eu%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"skavio-usdc-payment-verification-proof","type":"http","url":"https://www.skavio.eu/mcp"}'
```

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

`.vscode/mcp.json`:

```json
{
  "servers": {
    "skavio-usdc-payment-verification-proof": {
      "type": "http",
      "url": "https://www.skavio.eu/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": {
    "skavio-usdc-payment-verification-proof": {
      "serverUrl": "https://www.skavio.eu/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 skavio-usdc-payment-verification-proof --url https://www.skavio.eu/mcp
```

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

`config.toml`:

```toml
[mcp_servers.skavio-usdc-payment-verification-proof]
url = "https://www.skavio.eu/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http skavio-usdc-payment-verification-proof https://www.skavio.eu/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": {
    "skavio-usdc-payment-verification-proof": {
      "type": "http",
      "url": "https://www.skavio.eu/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://www.skavio.eu/mcp`.
