STREAMABLE HTTP
https://www.gasfree4you.com/mcpPrices and resource estimates are available. No account needed.
Personal Cursor configuration
Add the server to ~/.cursor/mcp.json. If the file already exists, add the gasfree4you entry to its mcpServers object, keeping your other servers.
mcp.json
{
"mcpServers": {
"gasfree4you": {
"url": "https://www.gasfree4you.com/mcp"
}
}
}Save the file, restart Cursor and check the server in MCP settings.
Cursor documentation ↗Add via Claude Code CLI
Run the command in your terminal. The user scope makes the server available across your projects.
Terminal
claude mcp add --transport http --scope user gasfree4you https://www.gasfree4you.com/mcpOpen a new Claude Code session and run /mcp to check the connection. To switch modes, first remove the existing entry: claude mcp remove --scope user gasfree4you, then add it again.
Codex configuration
Add this block to ~/.codex/config.toml. If the gasfree4you entry already exists, update it instead of creating a duplicate.
config.toml
[mcp_servers.gasfree4you]
url = "https://www.gasfree4you.com/mcp"Restart your client. In Codex CLI, run /mcp and check the available tools.
Use a client that supports Streamable HTTP and custom HTTP headers. Configure your API key manually; OAuth is not used.
Send your key only in a connection header: X-API-Key: YOUR_API_KEY or Authorization: Bearer YOUR_API_KEY. Use just one of them. Never send your key in chat, URLs or tool arguments, and never publish a configuration containing your key.

Four available tools. Set authentication in the connection’s HTTP headers, not in tool arguments.

estimate_transfer_fee | sender_wallet, recipient_wallet | No key needed |

energy:65000,130000or131000. The value130000is normalized to131000.- One order call buys one package, with no additional TRX top-up. The service determines the duration.
request_id: a unique UUID for a new order. Reuse this UUID and the same parameters when retrying that order.ORDER_PENDING_OR_UNKNOWN: check the history in the app or contact support; do not retry with a new UUID.API_KEY_REQUIRED: configure your key in the connection headers.
MCP does not provide order history or tracking, sanctions screening of addresses, or standalone on-chain queries. The price tool returns public prices, not an exact account-specific quote before an order.
