Overview

Zerion runs a remote MCP server at developers.zerion.io/mcp that lets AI agents query wallet token balances, transaction history, DeFi positions across 8,000+ protocols, NFT holdings, and PnL data through a schema normalized across chains. Builders point an MCP client (Claude, Cursor, etc.) at Zerion's hosted endpoint with a free API key rather than integrating Zerion's REST API directly. A free tier allows up to 10 calls/second and 2,000 calls/day.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — as documented by the project, not run by us

Runtime: Hosted MCP endpoint (no local install)

A remote server: your client connects to the project's endpoint. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

Answers a call
not asked — no read-named tool takes zero arguments and declares none that touch keys, addresses or amounts

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
