Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 13 tools.

The tools it lists (13, as of 7 hours ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
check_stablecoin_freezeCheck whether Tether (USDT) or Circle (USDC) have blacklisted a wallet address on-chain. Reads the issuer's blacklist function directly across 15 chains (ETH, BSC, POLYGON, ARBITRUM, OPTIMISM, BASE, AVALANCHE, PLASMA, HYPEREVM, STABLE, INK, BERACHAIN, ROBINHOOD, TRON, SOL). A frozen address can no longer send or receive that stablecoin. Also reports whether the address was PREVIOUSLY frozen and later unfrozen (a prior-freeze signal from the freeze ledger). The result reports the observed on-chain fact (frozen / not frozen at check time), never the cause of a freeze. Free.
get_freeze_eventsQuery the canonical stablecoin freeze ledger — the HISTORY of freeze / unfreeze / destroy events by Tether (USDT), Circle (USDC/EURC), Paxos (USDP) and First Digital (FDUSD), sourced from the issuers' own on-chain blacklist events across Ethereum, Polygon, Optimism, TRON and more. Filter by frozen address, chain, kind, or time; omit all filters for the most recent events. This is the EVENT HISTORY — to check whether an address is frozen right now, use check_stablecoin_freeze instead. Each row is a verifiable on-chain fact (issuer acted on address at block/time); it never states the cause. Free
check_token_securitySimulate a buy-and-sell of an ERC-20 token on its main DEXes to surface honeypots (tokens you can buy but not sell), extreme transfer taxes, name/symbol impersonation, and active mint authority — cross-referenced against BA's 1B+ entity labels. Reports observed facts (e.g. 'sell simulation reverted'), not verdicts. Live on Base, BNB Chain, Ethereum, Optimism, Polygon, Arbitrum. No transaction is sent. Free.
check_token_approvalsList a wallet's active ERC-20 token approvals on Ethereum and who can move its funds — risk-scored against BA's 1B+ entity labels (scam / phishing / exploit / sanctioned spenders), flagging unlimited allowances and stale grants. The wallet's attack surface at a glance. Read-only. Ethereum only. Free.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
io.blockchainanalysis/mcp, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
