@followed by the MCP server name and your instructions, e.g., "@fabtally-chain-mcpWhat's the current gas price on Ethereum?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
FabTally Chain — MCP server
On-chain monitoring reads an AI agent or dev polls per-call. Fronts the Chain HTTP API at https://chain.fabtally.com. Holds no private key.
Tools (all paid; a call with no payment returns the decoded x402 402 challenge)
Tool | Price | What it does |
| $0.001 | Resolve an ENS |
| $0.001 | Current gas for a chain via public RPC — base fee + suggested priority + max fee (gwei) at the latest block; optional at/below-threshold boolean. Args: |
| $0.003 | Next token vesting/unlock event(s) from DefiLlama's public emissions data — date, amount, % of max supply. Cleanly says so when there's no public schedule. Args: |
| $0.003 | Chainlink price-feed health — last-update age, latest answer, round monotonicity, stale flag vs heartbeat, optional deviation vs a reference. Args: |
Every tool also accepts an optional x_payment (base64 x402 payload) that is
forwarded as the X-PAYMENT header to settle the call and return the real result.
Humans can instead prepay by card and use an X-FabTally-Key credit key against
the HTTP API.
