RobotBase — three MCP editions for agents

00 / FOUR ENDPOINTS — PICK YOUR AGENT

One RobotBase, three audiences, four entry points.

Every edition includes the same 17-tool web toolbox as the free lead magnet. The difference is what sits next to it: on-chain truth, developer trends, or content and attention signals.

WEB3 EDITION

65 tools

BTC / ETH / XMR / ZEC / TRON verification and risk, prediction-market odds, crypto trends — plus all 17 web tools.

web3.robotbase.cc/mcp ↗

DEV EDITION

18 tools

GitHub, Hugging Face, npm, PyPI and Hacker News trends for coding agents — plus all 17 web tools for docs.

dev.robotbase.cc/mcp ↗

CONTENT EDITION

35 tools

Social hot lists, attention trends, 16 CyberLibrary book tools — plus all 17 web tools for research and SEO.

content.robotbase.cc/mcp ↗

COMPATIBILITY ALIAS

65 tools

The original robotbase.cc/mcp now resolves to the Web3 edition. Existing clients keep working.

robotbase.cc/mcp ↗

Free web allowance: 100 calls/day/IP per edition; x402 credit balance is shared across editions. No API key, no account, no subscription.

01 / THREE LAYERS, THREE EDITIONS

Find and read. Verify and price. Cite and dig deeper.

An agent that can search, read and verify does not need three vendors. Every layer below is available in the Web3, Dev and Content editions; all three share the same 17-tool web layer, one x402 credit balance and anonymous access.

L1 · Find & read NEW · LIVE

Search & Fetch

search · fetch · screenshot · map · batch · feed · metadata

The 17-tool web layer an agent uses most: search the live web, read public pages as clean Markdown, capture a real-browser screenshot, map a site, batch-fetch URLs, read RSS/Atom feeds, pull structured metadata, crawl, diff and monitor pages — no key, no browser code.

100 web calls/day per edition 17 web tools 1–3 credits after

Public pages only · robots.txt respected · no login or paywall bypass then credits via x402

L2 · Verify & price 5 CHAINS

Verify & Risk

btc/eth/xmr/zec/tron tools · tron_check_address_risk

Did the payment actually settle, what will the next one cost, and is the counterparty safe to touch — answered from mainnet nodes we operate, not a third-party RPC provider.

44 verification tools free 5 risk calls/day free 1 credit per risk call after

BTC · ETH · XMR · ZEC · TRON · 0 public RPC endpoints then credits via x402

L3 · Content edition 16 BOOK TOOLS

Books, social & attention

cyberlibrary_* · social_hot · attention_trend

80,354 public-domain books in 23 languages for citation-grade reading, plus social hot lists and attention trends. This layer is exposed on the Content edition (content.robotbase.cc); the deeper chain toolkits remain on Web3.

80k+ books 25 languages 5 book calls/day free

1–10 credits · retrieval 1–2 · chunks 2 · quote 3 · passages 5 · full-text 5 · semantic 8 · rag 10 then credits via x402

One loop search find the source → read clean Markdown → verify on-chain proof → pay x402 credits

02 / THE CHAIN ROSTER

Five chains we run ourselves. The rest is honest about what it cannot do.

Every chain answer on this endpoint comes from a mainnet node we operate — no third-party node provider in the trust path. Base and Solana data services were retired on 2026-10-18; they remain only as x402 payment rails, and no chain data is served for them. Nothing here is promised before a node exists.

LIVE · MAINNET NODES — No provisioning or planned chain is advertised. The sixth card is a sealed slot: no name, no ticker, no numbers and no tools — it contributes to no count.

03 / USE CASES

The questions agents actually arrive with.

Each card is a real prompt an autonomous agent can send to one of the editions — and the tools that answer it, with the free daily room before any credit is spent.

Question 01

"What changed in the Bitcoin fee market today?"

web_search btc_get_fee_rates btc_get_mempool_state 100 shared web calls/day

Question 02

"Read this article and pull out the settlement numbers."

web_fetch eth_get_transaction 100 shared web calls/day

Question 03

"Did this USDT transfer land — and is the sender tainted?"

tron_verify_usdt_transfer tron_check_address_risk 5 free risk calls/day

Question 04

"Find every mention of 'ledger' in Moby Dick."

cyberlibrary_fulltext_search cyberlibrary_search_books 5 free calls/day then 5 credits

Question 05

"Reconcile a merchant's XMR payouts for the week."

xmr_merchant_report xmr_wallet_balance xmr_verify_payment free verification

04 / CONNECT — PICK AN EDITION

Pick an edition. Connect in one paste.

One paste into Claude Desktop, Cursor, Codex or VS Code. All three editions speak Streamable HTTP / protocol 2025-06-18, every tool carries a "when to use / do not use / returns" description, and a slow node degrades the answer instead of failing the call.

05 / CAPABILITY MATRIX

Retention and boundaries, stated up front.

Retention is a property of the node, not a marketing decision. Where a node is pruned or window-limited, the boundary is stated here and enforced by the MCP instead of being approximated.

Chain	Node profile	Retention	What an agent can ask for
Live
BTC	Bitcoin Core 31.0 · full node · txindex · no pruning	complete	Fee targets for 1→24 blocks, mempool depth and floor, any transaction by id, any block, address activity, raw-transaction broadcast
ETH	Reth v2.7.0 + Lighthouse v8.2.3 · full execution and consensus state	state complete · history window set by node pruning	Head height, beacon slot, peer count, client versions, sync progress; settlement checks and event logs inside the retained window
XMR	monerod 0.18.5.3 · full node · not pruned · restricted RPC + read-only helper	complete	Node state, tx-pool depth, dynamic fee, block window, transaction lookup by hash, payment proofs, merchant ledger via view key
ZEC	Zebra 6.3.0 · full node · + lightwalletd compact-block filters	complete	Chain info, supply across all six value pools (incl. Ironwood), recent blocks, block attribution; compact-block filters for wallet sync
TRON	java-tron lite full node	recent blocks + recent TRC-20 transfer log	Recent blocks and TRC-20 transfer events for payment verification; governance proposals and witnesses; read-only contract calls not available: full-history index

06 / PRICING

Free to verify and free to try. One cent a credit past that.

Verification is free forever, the web and book/risk layers have daily free buckets, and everything past them is paid per call by the caller's own wallet over x402 — no key, no account, no subscription.

Risk & Library

5free calls/day, per IP

Web3 risk tools: 5 calls/day; Content CyberLibrary: 5 calls/day
Past that: risk 1 credit · retrieval 1–2 credits · full-text search 5 credits
Every metered answer carries its own _metering block
Coverage: 80,354 public-domain items in 23 languages

The paid tier is x402 machine payment. Over the free room, calls are settled in USDC on Base or Solana by the caller's own wallet: 10 credits for 0.10 USDC or 100 credits for 1.00 USDC — one US cent per credit. There is no API key, no account and no subscription. The authoritative pack sizes, assets and receiving addresses are always the live accepts[] array in the 402 response.

Base and Solana are payment rails only — no chain data is served for them. Their data tools were retired on 2026-10-18. The five-chain data surface is Bitcoin, Ethereum, Monero, Zcash and Tron. x402 payments still settle in USDC on Base or Solana; that is a payment rail, not a data service.

No API keys are issued by robotbase.cc. Any offer to sell you a RobotBase API key, on this site or elsewhere, is not us. Clients that cannot answer a 402 challenge yet? The whole free surface — every verification tool, plus the daily web and risk/book buckets — needs no wallet at all.

Check a balance without spending a call: GET /mcp/credits?payer=<the address that paid> returns the remaining credits, calls charged and the last payment. Address-keyed, no account, no key.

07 / TRUST & BOUNDARIES

Read-only by construction. Honest about the edges.

The gateway is designed so that trusting it does not require trusting a company's promises: no key is issued, no funds are held, and every boundary is published in the response that hits it.

Self-hosted nodes

0public RPC

One surface, our own machines

Every chain answer is read from a mainnet node we operate. 65 Web3 / 18 Dev / 35 Content tools across four endpoints.

Read-only / no custody

0funds held

It can only see

No private keys are requested, stored or used. Nothing is signed. Raw-transaction relay is disabled by default and only ever forwards a transaction the caller already signed.

Privacy

sha256[16]only ID stored

No query content in logs

The audit log stores path, method, status and a truncated hash of the client IP — no plaintext IPs, no query strings. Web queries and fetched URLs are not written to it.

Honest limits

~6days · Tron window

Stated, not approximated

Tron is a lite full node with a rolling ~6-day window; a local miss is never reported as "not found". Base and Solana data tools were retired on 2026-10-18 — payment rails only.

08 / ECOSYSTEM

Machine-readable, or listed where agents look.

Everything an agent, a registry or a human reviewer needs to verify this endpoint — no signup, no gate.

07 / QUESTIONS AGENTS ASK

Answers for humans and answer engines.

The six questions buyers and agents ask before they connect. Every answer is verifiable against the live endpoint and its machine-readable docs.

What is RobotBase MCP?

RobotBase publishes three read-only MCP editions where an agent can search the live web, read public pages as clean Markdown, verify on-chain payments and risk on Bitcoin, Ethereum, Monero, Zcash and Tron, and search 80,354 public-domain books: Web3 (65 tools), Dev (18) and Content (35). Calls are paid over x402 after free daily allowances.

Is RobotBase MCP free?

Yes for most work: Web3 verification tools are free forever; all web tools share 100 calls per IP per day per edition; Web3 risk tools and Content CyberLibrary tools each have 5 calls/day. No API key or account is required. Past the allowance, calls cost 1-10 USDC credits over x402.

Which blockchains does it support?

Bitcoin, Ethereum, Monero, Zcash and Tron, each read from a mainnet node RobotBase operates. Base and Solana are x402 payment rails only; no Base or Solana chain data is served.

Can it search the web and read pages?

Yes. web_search returns ranked results and web_fetch returns clean Markdown for one public page. The web layer also includes screenshot, map, batch, feed, metadata, crawl, extract and act tools. It respects robots.txt and never logs in or bypasses paywalls.

How do I connect Claude Code, Cursor or Cline?

Pick Web3 (https://web3.robotbase.cc/mcp, 65 tools), Dev (https://dev.robotbase.cc/mcp, 18) or Content (https://content.robotbase.cc/mcp, 35); https://robotbase.cc/mcp is the Web3 compatibility alias. Claude Code: claude mcp add --transport http robotbase-web3 https://web3.robotbase.cc/mcp.

Does RobotBase support x402 payments?

Yes. Credit packs are prepaid USDC paid by the caller wallet over x402 (USDC on Base or Solana): 10 credits for 0.10 USDC or 100 credits for 1.00 USDC. The endpoint never holds funds, takes custody, or issues API keys.
