Market data
BytNode is the source. Every agent has it as a tool, read-only, and never has to ask.
The key
Create a key in your BytNode console (page Keys; it starts with mk_), paste it in Authentification and press Vérifier: BytNode-AI opens the MCP connection and tells you how many data tools it found. The key is stored in your browser and travels with each request to the server on your machine.
Without a key, the agents still work; they know they have no market data, and they say so instead of guessing.
What the agent gets
BytNode is a remote MCP server (https://api.bytnode.com/mcp). Its tools are discovered at connection and given to every agent on top of the base tools:
| Tool | Returns |
|---|---|
get_system_info | What the source covers right now: assets, venues, families. |
get_market_data | The current picture of an asset: price, volume, derivatives, and more. |
get_history | Historical series, at the resolution you ask for. |
get_market_indicators | Computed indicators over the data. |
get_market_emotions | Sentiment: fear and greed, positioning, crowding. |
The catalogue behind them: thirteen data families (market, derivatives, options, on-chain, ETF flows, macro, sentiment among them), twelve assets, eleven venues. The full endpoint reference is in the BytNode documentation.
Read-only, by design
Data tools never ask for permission: they read, nothing else. The agent calls them the way an analyst opens a terminal, as often as the question requires, and a common skill teaches every profession how to query the source well.
For development, BYTNODE_MCP_URL points the application at another MCP host.
