Overview

AI-generated overview

Remote MCP server that returns signed, receipt-backed measurements of x402 sellers on Base and remote MCP servers before an agent pays them.

What you can do
  • Look up one host: latest unpaid probe, freshness, listing price and payTo, receipt link
  • Search covered x402 sellers and remote MCP servers for a need, with a one-line factual reason
  • See coverage totals, discovery sources and last probe run
  • Fetch a real sample of a paid answer for a fixed example
  • Get measured facts and receipt history for one host, or top 3 providers for a task ranked by reliability, price or latency (paid tools return an x402 URL to GET rather than paying)
When to use it
Useful when an agent is about to pay an x402 service or connect to a remote MCP server and you want independent, signed evidence of its recent behaviour, price and payTo before committing. Also handy for comparing candidate paid providers for a task.
Requirements
Remote Streamable HTTP endpoint at botsrated.com/mcp; no install, no auth and no API key for the free tools. Paid tools need an x402-capable client and USDC on Base mainnet; free daily quotas apply per client IP. Network access to botsrated.com.
Before you install
Paid tools cost USDC on Base mainnet (check, report, best) after free daily quotas; the MCP tools themselves do not pay, they return an x402 URL you must GET with your own client. Seller-supplied text in results is untrusted and should not be followed as instructions. Results are measurements, not ratings of a seller.

Installation

In SourceWeft

  1. Open BotsRated (beta) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.botsrated%2Fbotsrated/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

BotsRated: MCP server

Signed checks of paid AI services, before your agent pays.

BotsRated measures paid AI-agent services with signed receipts. BotPulse is a separate digest and alerts product; these measurements do not claim coverage of every delivery outcome.

BotsRated publishes timestamped, receipt-backed measurements of paid x402 agent services on Base:

  • unpaid probes: status, whether the 402 challenge is valid, latency, quoted vs listed price, and payTo;
  • paid test-buys, each with its on-chain tx hash.

It reports facts and signed receipts only.

This repository documents the remote MCP server (nothing to install or run for it) and the optional Guard packages below.

Guard: check a payment before your agent signs it

Guard pairs with the x402 client your agent already pays with. It does not replace your agent runtime. Free. No key for local attach. It compares each payment request with BotsRated measurements and warns or blocks by your own rules. Facts and receipt links, not grades. Guard does not hold funds.

Facts bundle (preflight and check)

preflight (the MCP tool and GET /v1/preflight?url=<host>) returns measurements and receipt links. You set your own thresholds. The response is measurements and a receipt link.

FieldWhat you get back
found, hostWhether this host is in the probe record, and the host name
latest_probeLatest unpaid probe: ts, status, valid_402, latency_ms, observed amount (live_amount), observed payTo (live_payTo), live_network
latest_probe.receipt_urlLink to the signed receipt for that probe (https://botsrated.com/receipt/...). The receipt is the record
freshnesslast_probe_at, age_seconds, stale (older than 24 h)
listingDirectory price and payTo. Directory data is not a probe observation
recent_windowProbe count, how many returned a valid 402, latency. A count in a window
noteFacts only

check (paid, after the free daily quota) adds measured facts for one host and the last receipts. Those are still measurements and receipt links.

The payment guard in @botsrated/x402-preflight and botsrated keeps a smaller local bundle from this response (covered, host, knownPayTos / known_pay_tos, listingPayTo / listing_pay_to, observedNetwork / observed_network, observedAmount / observed_amount, stale, receiptUrl / receipt_url). Pick a named preset (warn, carefulBuyer, or dry-run-only) there. The guard does not invent a summary number from these fields.

Paid MCP tools: an unpaid call returns an x402 v2 PaymentRequired tool error (isError, structuredContent with accepts); an x402-aware MCP client (e.g. @x402/mcp) retries with the payment in _meta["x402/payment"]. The same data is on the HTTP routes, payable by any x402 client (e.g. @x402/fetch, Coinbase Agentic Wallet). All three paid routes are also listed in the Coinbase x402 Bazaar.

Free daily quota: the first 25 checks and 3 reports per client IP (IPv6 per /48) per UTC day are answered without payment; after that the normal x402 402 applies. /v1/find spends one check from that same quota. /v1/best has no free quota. Preflight stays free, no key, rate limits. No accounts, prepaid balances or stored credit. The badge is free and earned, never sold. Details: https://botsrated.com/pricing

Plans (seller alerts and data plans)

One x402 USDC payment on Base buys one 30-day period. There is no balance and no auto-renewal. Cancelling stops delivery. The dataset stays free.

Pro: watch up to 50 sellers or tools; alert to webhook, Slack, Discord or email. $19 / month by card + tax, or $29 / 30 days USDC. Tools you rely on (for example OpenAI, Anthropic, Gemini, Pinecone, Supabase) use those same 50 slots. No separate plan.

PlanPrice per 30 daysWhat you get
alerts-free$0Watch 1 seller. Daily digest: one email per UTC day when its facts change. Slack, Discord, and webhook need a paid plan (paid_channel_required). Up to 3 free alerts per client IP, 1,000 in total
alerts-50$29Up to 50 sellers or tools; a signed webhook within one probe cycle of a change (payTo, quoted price, valid 402, listing, freshness)
data-starter$49Bearer token for /v1/check, /v1/report, /v1/best without per-call payment (60 requests/min)
data-pro$199Same, 600 requests/min, plus the change-event export (GET /v1/export/changes.ndjson?host=)
custom$499+ per 30 daysVolume or bulk delivery; support terms agreed per contract: [email protected]

Paid BotPulse plans are retired; the feed stays free. Plans already bought keep working until their 30-day period ends. Free reads stay at https://botsrated.com/v1/botpulse/latest and https://botsrated.com/v1/botpulse/feed.json. Alerts on tools use Pro's 50 slots.

Subscribe with POST https://botsrated.com/v1/alerts/subscribe (free) or POST https://botsrated.com/v1/subscribe/{plan} (x402). The body and the webhook are checked before any 402. The webhook must answer the verification POST with the challenge; it must be https on a public DNS name, and redirects are not followed. Free alerts are email only: one confirmation link first, then plain-text alerts from [email protected]. Slack, Discord, and webhook delivery need a paid plan (paid_channel_required on the free plan). Paid alert plans can use a signed webhook (Ed25519, botsrated-prober-1, see below, over {"m":"<timestamp>.<raw body>"}), a Slack incoming webhook or Discord channel webhook (plain text, not signed), or the same email path. Manage a subscription with GET /v1/subscription and POST /v1/subscription/{cancel,update} plus Authorization: Bearer <token>. Full details: https://botsrated.com/v1/plans

Methodology, replies

  • Methodology: https://botsrated.com/methodology
  • A seller can send a reply about a measurement for free: https://botsrated.com/disputes (POST /v1/dispute). The measurement is re-checked and the reply is published next to the data. A measurement is a signed record, not a finding about the seller.
  • Dataset signature: https://botsrated.com/dataset.sig.json. Key set: https://botsrated.com/.well-known/botsrated-key
  • Receipt format v0.2.1 (draft; mcp_probe receipts for remote MCP servers; v0.2.1 updates reference schedules and MCP retention) and verifier: spec/SPEC.md. node spec/verify.mjs '<receipt.json|url>' needs verify.mjs, verify-core.mjs, and verify-node.mjs in one directory. verify.mjs alone does not run.
  • Free: preflight, then the receipt link, then the signature check. x402 preflight puts it on latest_probe.receipt_url. MCP preflight puts it on servers[].latest_receipt_url (keep ?mcp=&day=&s=). CLI, single quotes: node spec/verify.mjs '<receipt_url>'. The pasted URL is a 20-hex id plus allowlisted host, mcp, day, and s only. A matching signature checks that record only. It is not a rating of the seller. The same check is importable as verifyReceipt from @botsrated/x402-preflight/verify-receipt (Node, offline; status signature valid, signature invalid, key unknown, or redacted copy). A copy with withheld_fields or withheld_note is redacted copy: not offline-verifiable, and not signature invalid. Check the stored record with GET /v1/verify. spec/receipt-page.mjs is that same check for Accept: text/html. It is not on the live host until Pages returns it (Content-Security-Policy header, and /spec/verify-browser.mjs plus /spec/verify-core.mjs). spec/courthouse/ is the same check as a folder you serve yourself.

Signing keys (Ed25519)

Raw 32-byte public keys, base64. Fingerprint = sha256 of the raw key bytes. A signature is valid for an object whose own timestamp (ts, or generated_at for snapshots) lies in [valid from, valid until). The live key set at /.well-known/botsrated-key is authoritative; this table is an out-of-band copy to compare against.

Preflight (Free)

FREE. Is this x402 seller or remote MCP server covered, and what did its latest unpaid probe show? For MCP server hosts: last handshake state (ok, auth_required, handshake_failed, unreachable, or blocked = not contacted because the URL, a redirect or its DNS points somewhere our safety rules don't allow), protocol version, tool count and tools hash. Returns status, whether the 402 challenge was valid, quoted vs listed price and payTo, freshness (age, stale flag) and the receipt link. Use before paying any x402 seller. Free and unlimited (normal rate limits).
