ChainVerdict — chainverdict.xyz

Checks an autonomous agent runs before it moves money or trusts a counterparty: token safety verdicts and wallet risk profiles on Base, on-chain payment verification, financial-identifier validation, and live domain security posture.

Every call is paid per request in USDC on Base over the x402 protocol — no accounts, no API keys, no signup. Every response carries an evidence record saying what was checked, how fresh it is and what it does not establish, and is Ed25519-signed. No LLM inference anywhere: every answer is a deterministic computation or a live read of external state, so the same input returns the same answer forever.

MCP server

ChainVerdict is a remote MCP (Model Context Protocol) server, built on the official @modelcontextprotocol/sdk and served over Streamable HTTP at:

https://chainverdict.xyz/mcp

It is published in the official MCP registry as xyz.chainverdict/chainverdict.

initialize and tools/list are free, so registries and clients can index the server without paying.
tools/call is x402-paid at the price of the route behind the tool — except payment_info, which is free.
20 MCP tools, all read-only and idempotent, annotated with readOnlyHint / destructiveHint / idempotentHint / openWorldHint.
No MCP resources or prompts are exposed; this server is tools-only.

Tool descriptions interpolate the live price from the same map the payment middleware charges from, so tools/list can never advertise a rate that is not the rate. test/mcp-parity.test.js fails the build if a tool exists for a route that is no longer sold, or if a sold route has no tool.

Tools

Tool	What it answers
`payment_info`	Free. How x402 payment works, the price of every tool, where payments settle.
`token_verdict`	Is this ERC-20 on Base a scam, a honeypot, or safe to hold?
`wallet_dossier`	Wallet risk profile for a Base address before you pay it.
`verify_payment`	Decode and confirm an on-chain payment on Base.
`verify_token`	Resolve a symbol or address to the canonical Base token.
`validate_iban` `validate_vat` `validate_bic` `validate_lei` `validate_isin`	Deterministic check-digit and format validation.
`security_email` `security_tls` `security_typosquat`	SPF/DMARC/DKIM posture, live TLS probe, brand look-alike analysis.
`data_gas` `data_block` `data_token_supply` `data_token_activity` `data_portfolio`	Live Base chain reads.
`html_to_markdown` `text_diff`	Document utilities.

POST /v1/batch/validate is HTTP-only by design: 500 identifiers do not belong in a tool-call argument.

HTTP rate card

Every endpoint answers an unpaid request with a 402 quote.

Ops

Stateless. No database, no cron, no maintained data set. Sources are pure arithmetic over public specifications plus live Base RPC.

Limitations

These are informational signals. None is a compliance control, none discharges a legal obligation, and none is regulated financial, legal or compliance advice. A valid signature proves a response came from this service unaltered — not that the answer is correct. A signed wrong answer is still wrong, and still signed.
