High risk

We rate an entry high when the tool writes to external systems, handles money, production databases or secrets, or runs arbitrary commands. The CLI installs it only with your consent.

Why this level

  • The agent can automatically spend real USDC cryptocurrency on every call without separate confirmation
  • The wallet connected for payment is directly accessible to the tool

saymon-agent/payforapi

Install

In your terminal, with SkillFoxx CLI

npx skillfoxx add mcp/saymon-ru-data-api

Detects the agents on your machine, checks the risk and pins the version.

Other ways to install

This entry is high risk, so there is no one-click install. Review the code and add the config by hand.

Run in a terminal

claude mcp add --transport http payforapi https://payforapi.com/mcp

Or add to the file .mcp.json, in the project

{
  "mcpServers": {
    "payforapi": {
      "type": "http",
      "url": "https://payforapi.com/mcp"
    }
  }
}

If the file already exists, add the server inside the mcpServers key.

Add to the file ~/.cursor/mcp.json, for all projects

{
  "mcpServers": {
    "payforapi": {
      "url": "https://payforapi.com/mcp"
    }
  }
}

If the file already exists, add the server inside the mcpServers key. For a single project, put the same block into .cursor/mcp.json.

Run in a terminal

code --add-mcp '{"name":"payforapi","type":"http","url":"https://payforapi.com/mcp"}'

Or add to the file .vscode/mcp.json, in the project

{
  "servers": {
    "payforapi": {
      "type": "http",
      "url": "https://payforapi.com/mcp"
    }
  }
}

If the file already exists, add the server inside the servers key.

Run in a terminal

codex mcp add payforapi --url https://payforapi.com/mcp

Or add to the file ~/.codex/config.toml, for all projects

[mcp_servers.payforapi]
url = "https://payforapi.com/mcp"

If the file already exists, append the block to the end.

Run in a terminal

gemini mcp add -s user -t http payforapi https://payforapi.com/mcp

Or add to the file ~/.gemini/settings.json, for all projects

{
  "mcpServers": {
    "payforapi": {
      "httpUrl": "https://payforapi.com/mcp"
    }
  }
}

If the file already exists, add the server inside the mcpServers key.

Add to the file ~/.config/devin/mcp_config.json, for all projects

{
  "mcpServers": {
    "payforapi": {
      "serverUrl": "https://payforapi.com/mcp"
    }
  }
}

If the file already exists, add the server inside the mcpServers key. Legacy Cascade keeps the MCP config in ~/.codeium/windsurf/mcp_config.json.

    }
  }
}

If the file already exists, add the server inside the mcpServers key. Open the settings file in Cline: MCP Servers tab, Configure MCP Servers.

Add to the file .roo/mcp.json, in the project

{
  "mcpServers": {
    "payforapi": {
      "type": "streamable-http",
      "url": "https://payforapi.com/mcp"
    }

Text for your agent

Connect the remote MCP at https://payforapi.com/mcp, or build the local bridge with docker build -t saymon-ru-data-api-mcp . and run it with the PAYFORAPI_MCP_URL variable; paying for calls requires a wallet with USDC on Base.

Other ways from the author

  "mcpServers": {
    "payforapi": {
      "url": "https://payforapi.com/mcp"
    }
  }
}

The remote MCP server; calls are paid in USDC on the Base network.

This is third-party code. Review the repository files before installing.

What it does

The service provides 15 MCP tools for Russian data: a company check by INN through the EGRUL state registry, self-employed NPD status via the tax service, Runet search through Yandex, converting a Russian-language page to Markdown, seller or company dossiers, Russian Post rates, tracking and addresses, Central Bank of Russia rates, and Moscow Exchange quotes. Every call is paid separately in USDC on the Base network via the x402 protocol: the agent signs a payment authorization message and gets a response with no registration or API keys. There is a remote HTTP MCP and a local stdio server in Docker that proxies calls to the same paid endpoint.

Who it is for. For agents and developers outside Russia who need legal access to Russian-language data without opening an account in every individual Russian service.

Good fit when

  • You need a one-off company check by INN without setting up an account in a data service
  • You need to search and parse Russian-language pages without a Yandex account
  • You need to track a Russian Post parcel or estimate a shipping rate without direct API access

Not a fit when

  • You have no USDC wallet on Base: without it no call goes through
  • You need free or cost-predictable requests: the service charges money per call
  • You need direct official access to EGRUL, the tax service, Russian Post, CBR or MOEX: this is a paid intermediary layer on top of them

Example request

Check the Russian company with INN 7707083893 via EGRUL and show its OGRN and registration date

Limitations

Payment runs through USDC cryptocurrency on Base via the x402 protocol; there is no regular billing account or card option. The service has no open source for the proxy itself beyond a thin local bridge (server.py) and a tool catalog. There is no free tier or trial, every call costs a few cents or more. The service's own marketing clearly targets agents outside Russia rather than Russian users who already have direct access to the same government services.

How to disable. Remove the server from your MCP client configuration or stop the local Docker bridge container.

  • The wallet connected for payment is directly accessible to the tool

README in short

The multi-language README describes 20 paid REST endpoints priced in USDC: INN company checks and self-employed status, Runet search and page parsing, seller and company dossiers, Russian Post services, CBR rates and MOEX quotes, plus a referral program paying 20% of referred agents' revenue. It separately covers a remote 15-tool MCP and a local Docker stdio bridge for clients without remote server support.

FAQ

Do I need an API key or account?

No, instead of keys and sign-up every call is paid directly in USDC via the x402 protocol.

Can the server run offline?

The local Docker stdio server answers initialize and tools/list with no network, but actual tool calls are still proxied to the paid remote endpoint.
