DeFi Protocol Activity Index -- quantitative on-chain activity metric from DefiLlama data
Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security71
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 403, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Tool Safety0
- Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Capabilities0
- Capabilities blocked by authentication: the endpoint requires auth we don't have to read them. See how to fix → Unverified
Unverified: 6 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm. Claim this server and supply a read-only token to verify it and lift the score.
How do I install the io.github.nexus-mcp-infra/onchain-activity-index server?
io.github.nexus-mcp-infra/onchain-activity-index is a hosted endpoint at https://onchain-activity-index-325572559480.us-central1.run.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_onchain_activity_index ~146
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.

io.github.nexus-mcp-infra/onchain-activity-index exposes 1 tool: get_onchain_activity_index. Their descriptions and schemas cost roughly 146 tokens of context every time the server is loaded.
Does the io.github.nexus-mcp-infra/onchain-activity-index server require authentication?
Yes. io.github.nexus-mcp-infra/onchain-activity-index asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the io.github.nexus-mcp-infra/onchain-activity-index server still maintained?
io.github.nexus-mcp-infra/onchain-activity-index is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
