What you can do
  • Fetch market and network data: crypto spot prices, FX reference rates, DeFi TVL, DNS records, on-chain balances and time-zone conversion
  • Run deterministic utilities: hashing and HMAC, regex matching, text diffs, CSV/JSON conversion, verifiable randomness from a drand beacon
  • Clean and review data and code: CSV/TSV/JSON table cleaning, line-numbered code review, URL metadata and on-page SEO audits
  • Produce AI-written text work: translation, summarization, entity and keyword extraction via Cloudflare Workers AI
  • Map a public site or API: capability and entry-point reports, plus a consolidated due-diligence pack with on-chain balances
  • Query the operator's own surfaces: paid-service catalog, perk…
When to use it
Useful when an agent needs small, sourced, one-off results without signing up for several APIs: market and FX figures, quick code or data checks, or a read-only capability map of a public site. Most calls are micro-priced, so it suits occasional lookups rather than high-volume pipelines.
Requirements
Remote streamable HTTP endpoint; no account or API key. Paid tools require an x402 client and a funded USDC wallet on Base, Arbitrum, Polygon or Solana mainnet, with a PAYMENT-SIGNATURE header on retry. A few deterministic tools have a free per-IP daily quota.
Before you install
Most tools spend real money per call, from fractions of a cent up to 1.00 USDC for the diligence pack; check the 402 quote before retrying. Payment goes through an external x402 facilitator and is verified on-chain. Text sent to translate, summarize, entities, keywords and code review is processed by a third-party AI model. Reports are read-only and do not bypass authentication.

Installation

In SourceWeft

  1. Open Wealth Agent 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/io.github.jukky-source%2Fwealth-agent/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

Wealth Agent

Self-running, pay-per-call tool shop for AI agents. 26 tools priced in USDC via x402, no accounts, no API keys: an agent POSTs, gets a machine-readable 402 price quote, pays through any x402 facilitator, retries with the payment signature, and receives the deliverable.

Live: https://wealth-agent.wealthagent-app.workers.dev

How a purchase works

POST https://wealth-agent.wealthagent-app.workers.dev/api/x402/brief          # no payment  -> 402  PAYMENT-REQUIRED header + JSON body (accepts[], bazaar extension, vendor block)  -> pay with any x402 client (exact scheme, USDC)  -> retry the same POST with the PAYMENT-SIGNATURE header  -> 200  deliverable JSON

Settlement runs through an external x402 facilitator; payments verified on-chain before delivery. Tests from the operator's own wallets are tagged self-test and excluded from revenue.

Networks and prices

  • USDC on Base (eip155:8453), Arbitrum (42161), Polygon (137), and Solana mainnet — the exact accepts[] set ships in every 402 quote.
  • Micro-priced per call: roughly $0.0005–$0.01 for most tools; the full-surface diligence-pack bundle is $1.00 flat.

Free tier

Four deterministic products (crypto-price, fx-rates, dns-lookup, time-convert) are sampleable without payment at /api/free/<resource> — 25 calls per IP per UTC day (url-meta gets 5). No sign-up.

Discovery surfaces

  • /.well-known/x402.json — x402 discovery feed (canonical URLs)
  • /llms.txt — LLM-facing catalog with per-venue attribution tags
  • /agents.json, /openapi.json, server.json
  • POST /mcp — MCP (JSON-RPC) endpoint, protocolVersion 2025-06-18
  • /api/discwatch/public — daily discovery audit (which products are accepted/indexed on external x402 indices)
  • Listed on the Coinbase CDP x402 Bazaar

Trust

  • Payments only after on-chain verification; failed/undelivered jobs go to a refund-or-redeliver approval queue (POST /api/contact).
  • Self-test wallets are excluded from reported revenue.
  • The KPI funnel and receipts are internal; the public audit surfaces are discwatch and the on-chain payment records themselves.

Operations

Cloudflare Workers + D1 + Workers AI (free tier, neuron-capped) + a Containers-backed runner. Cronticks every 5 minutes drive scouting, discovery audits, IndexNow pings, and the free-tier reaper. Deploy:

CLOUDFLARE_API_TOKEN=... npx wrangler deploy -c wrangler.containers.toml

Secrets (OWNER_TOKEN, RUNNER_TOKEN, payment config) are injected via wrangler secret put and never committed.

crypto-price

Spot prices for up to 10 crypto symbols in one call, quoted in the currency you name (default USD). Each price names the venue that answered (Coinbase spot, Kraken ticker as fallback) and the exact URL it was read from, and every symbol that could not be priced is listed in gaps instead of being guessed or silently dropped. Use it to price an asset before a transfer, mark a position, or check a quote your counterparty gave you. Paid per call via x402 (USDC on Base, no account, no API key). 【価格】0.00 USDC。【使い方】呼ぶと 402 と PAYMENT-REQUIRED（支払い条件）が返る。USDC で支払い、同じ引数に PAYMENT-SIGNATURE ヘッダを添えて再送すると結果が返る。

Parametersquotesymbols

fx-rates

Foreign-exchange reference rates for a base currency and up to 12 target currencies, with the reference date and the source that answered. Primary path is the ECB-based frankfurter.dev feed; if it is unavailable the call falls back to a second provider and says so in the report rather than hiding the substitution. Currencies the source does not publish are listed in gaps. Use it to convert amounts, sanity-check an invoice, or settle a cross-currency budget.

Parametersbasesymbols

defi-tvl

Total value locked read from DefiLlama: pass a protocol slug (for example aave) for that protocol TVL, or omit it to get the top chains ranked by TVL, or filter by one chain. Every figure is the aggregator value at the time of the call, with the source URL attached, and any missing section is listed in gaps. Use it for DeFi due diligence, chain comparison, or a quick read on where liquidity sits.

Parameterschainlimitprotocol

dns-lookup

Resolve one hostname for one record type (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA) over DNS-over-HTTPS, returning every record with its TTL, the resolver that answered and the DNS response code. It tries a second resolver before giving up, and when nothing comes back it says so with the rcode instead of reporting an empty success. Use it for email deliverability checks, domain ownership evidence, or pre-flight checks before calling an API.

Parametersnamerequiredtype

crypto-hash

Deterministic hashing on the server: SHA-256, SHA-384, SHA-512 or SHA-1 over your text, or HMAC with the same digests when you pass a key. Returns the lowercase hex digest and the input byte length; the HMAC key is never echoed back. Same input always gives the same digest, so any third party can recompute and verify it.

Parametersalgotextrequiredhmac_key

time-convert

Convert one instant into the local time of up to 12 IANA time zones at once, with the UTC offset in minutes for each, plus the Unix seconds and the canonical ISO-8601 UTC form. Daylight saving is handled by the runtime time-zone database, and an unknown zone is reported in gaps rather than skipped. Use it to schedule across regions, check business hours, or turn an ambiguous timestamp into an unambiguous one.

random

Generate verifiable random values: up to 64 integers in a range, or a fair pick of n items from your own list, derived from a drand League of Entropy beacon round and returned together with the round number, the beacon randomness, its BLS signature and the exact derivation, so any third party can recompute and check the draw. Use it for lotteries, sampling, nonces, seat allocation and tie-breaks where the caller must be able to prove the result was not rigged.

Parametersnmaxminsaltroundchoices

onchain-balance

Read one EVM address and return its native coin balance and up to five ERC-20 token balances on Base or Ethereum, every figure tied to the block height it was read at. Token decimals are read on-chain from the contract, not assumed, and a token whose read fails is reported as an error rather than as zero. Use it to check a wallet before paying it, to confirm funds arrived, or to size a transfer without running your own node. The caller names the ERC-20 contracts, so no token list goes stale....
