Nothing serious here today

Today is the operative word: we check Onchain Activity Index every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

onchain

get_onchain_activity_index

Returns a 0-100 quantitative DeFi Protocol Activity Index for a DefiLlama protocol slug (e.g. 'uniswap', 'aave'), built from real TVL trend, fee/volume activity trend, chain diversification, and scale data. This is a pure descriptive metric, NOT a trading signal or financial recommendation of any kind -- it does not predict price movement and should not be interpreted as advice to buy, sell, or hold any asset. This MCP tool call is currently free -- the equivalent REST endpoint (POST /activity-index) is charged via x402, see README.

Onchain Activity Index — questions

Answers built from our own checks of this server.

What can Onchain Activity Index do?

It exposes 1 tools, read directly from the server on our last check. Among them: get_onchain_activity_index. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Onchain Activity Index working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 294 ms. The bar chart above shows every period we have measured.

How do I connect Onchain Activity Index?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own credentials: it refuses anonymous clients.

Does Onchain Activity Index need an API key?

Yes. Every time we knock, Onchain Activity Index answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Onchain Activity Index?

It answers our handshake in 294 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Onchain Activity Index open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
