Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ens
ens_expiry
PAID $0.001 (x402, USDC on Base). Resolve an ENS .eth or Basename .base.eth name's registration expiry ON-CHAIN (public RPC). Returns expiry date, days-left, whether it's in the 90-day grace period, the release date it becomes registrable again, and the current owner. Read-only, descriptive. Args: name. Without payment returns the x402 challenge; pass x_payment to settle.
gas
gas
PAID $0.001 (x402, USDC on Base). Current gas for a chain via public RPC: base fee + suggested priority + suggested max fee (gwei) at the latest block. If below_gwei is set, also returns whether the base fee is at/below your threshold right now. Read-only. Args: chain (ethereum|base|arbitrum|polygon|bsc|optimism), below_gwei (optional). Without payment returns the x402 challenge; pass x_payment to settle.
oracle
oracle_health
PAID $0.003 (x402, USDC on Base). Chainlink price-feed health via public RPC: last-update age, latest answer (scaled by decimals), round monotonicity (is the answer current?), a stale flag vs the heartbeat, optional deviation vs a reference price, and per-factor flags. Read-only, descriptive. Args: feed_address, chain, heartbeat_seconds (optional), reference (optional). Without payment returns the x402 challenge; pass x_payment.
token
token_unlocks
PAID $0.003 (x402, USDC on Base). Next token vesting/unlock event(s) from DefiLlama's PUBLIC emissions dataset: upcoming unlock date(s), token amount, and % of max supply, with a human description. Cleanly says so when a token has no public unlock schedule. Read-only, descriptive — NOT a price signal. Args: token (symbol, protocol name, or contract address), chain (optional, for address lookup). Without payment returns the x402 challenge; pass x_payment to settle.

FabTally Chain — questions

Answers built from our own checks of this server.

What can FabTally Chain do?
It exposes 4 tools, read directly from the server on our last check. Among them: ens_expiry, gas, oracle_health, token_unlocks. 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 FabTally Chain 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 134 ms. The bar chart above shows every period we have measured.
How do I connect FabTally Chain?
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.
Does FabTally Chain need an API key?
No. FabTally Chain completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is FabTally Chain?
It answers our handshake in 134 ms on average, which is faster than 77% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is FabTally Chain open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
