Security Report
FabTally Chain MCP is a well-architected, read-only on-chain monitoring server with proper authentication via x402 payment challenges. Code is clean with appropriate error handling, minimal dependencies, and no dangerous patterns. Permissions are narrowly scoped to HTTP network calls to a single API backend. Minor code quality observations (broad error catches, limited input validation on some fields) do not materially impact security given the server's read-only, stateless nature. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity).

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.
