MCP Server: ai.tokenos/gas-tracker

The MCP server ai.tokenos/gas-tracker provides live fees on five chains. It is identified by the slug ai-tokenos-gas-tracker and described as a service focused on returning up-to-date gas/fee information across multiple blockchain networks.

🛠️ Key Features

Live fees
Coverage across five chains

🚀 Use Cases

Checking current transaction costs on supported chains
Comparing fee levels across five networks

⚡ Developer Benefits

Single source for live fee data for five chains

⚠️ Limitations

Fee coverage is limited to five chains (as stated in the description)

Captured live from the server via tools/list.

gas_now

Parameters2

chains	array	optional	Subset of chains (default all)
speed	string	optional	Tier used for the USD cost columns (default standard)
