BridgeNode MCP server

BridgeNode is a helper that lets your AI assistant send chat requests to a range of AI models and pay for them one at a time, using Solana USDC. It is handy if you want to try different models without signing up for each one or managing API keys. There are free models and a couple of free tries on paid models, so you can test it before spending anything.

What this MCP server does

You ask your AI a question or a task in your normal chat. Your AI passes that request to this helper, which sends it to BridgeNode over the internet. BridgeNode runs it on the model you picked and, if it is a paid model, asks for a small payment in Solana USDC. The helper signs that payment automatically from a wallet you set up, but only after checking it is within your spending limits. Then the answer comes back and appears in your chat like a normal reply.

• “Ask a free model to summarize this paragraph for me”
• “Send this question to a paid model and show me the answer”

What it gives back to you

You get the model's answer as text in your chat, just like a normal reply. When you ask for the model list, you get a list of model names. When you ask for a price estimate, you get a number for the expected cost. If a payment was made, the helper handles it quietly in the background.
