Problem:
The tool mcp_coincap_mcp_list_assets, intended to list available crypto assets using the CoinCap API, is currently not functioning correctly. Initial attempts to use the tool resulted in errors or interruptions.
Investigation:
To diagnose the issue, the underlying API endpoint likely used by the tool was tested directly using curl:
curl https://api.coincap.io/v2/assets
This command successfully reached the endpoint, but received the following response:
{
"data": {
"message": "We are deprecating this version of the CoinCap API on March\n31, 2025. Sign up for our new V3 API at \nhttps://pro.coincap.io/dashboard"
},
"timestamp": 1744157618987
}Conclusion:
The response indicates that the CoinCap API v2 endpoint (https://api.coincap.io/v2/assets) is being deprecated. This is highly likely the reason the mcp_coincap_mcp_list_assets tool is failing, as it may be expecting the old v2 data format and cannot handle the deprecation notice.
Suggested Action:
The mcp_coincap_mcp_list_assets tool needs to be updated to use the new CoinCap API v3. Alternatively, if updating is not feasible, the tool should be temporarily disabled or removed to avoid confusion.
