README
# 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 | |------|-------|--------------| | `ens_expiry` | $0.001 | Resolve an ENS `.eth` / Basename `.base.eth` name's registration expiry on-chain — expiry date, days-left, 90-day grace status, release date, current owner. Args: `name`. | | `gas` | $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: `chain`, `below_gwei?`. | | `token_unlocks` | $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: `token` (symbol/name/address), `chain?`. | | `oracle_health` | $0.003 | Chainlink price-feed health — last-update age, latest answer, round monotonicity, stale flag vs heartbeat, optional deviation vs a reference. Args: `feed_address`, `chain`, `heartbeat_seconds?`, `reference?`. | 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. ## Transports - **stdio** (portable): `npx fabtally-chain-mcp` (bin: `fabtally-chain-mcp`) - **streamable-http** (hosted): `https://chain.fabtally.com/mcp` Config: `FABTALLY_CHAIN_BASE` (default `https://chain.fabtally.com`). Read-only, keyless, stateless, descriptive market-data/utility reads. Operated by Sunstone Soft (fabtally.com). **Not financial advice, not a signal, not a prediction.** The stateful "alert me when …" delivery is a separate product (the FabTally Alerts Telegram bot).
