Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account rmartins1451 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Losbeto gives an assistant paid market-intelligence tools — forex, stocks, Brazil macro, crypto and Base chain data — billed per call in USDC via x402.

What you can do: Search and list the endpoint catalog, with prices and parameters, and check subscription or credit status
Fetch market data for forex, stocks, Brazil central-bank macro, commodities, crypto and Base chain reads
Pull a whole area in one call: Brazil, global or crypto snapshot
Query chain data: latest block, gas price with forecast, wallet balances, ENS resolution, transaction details
Look up ERC-8004 agent reputation, graded wallet verdicts, launch risk and oracle price consensus
Watch third-party x402 endpoints for price or availability changes pushed to a webhook
When to use it: Useful when an assistant needs on-demand financial and on-chain market data, especially Brazil macro and Base chain reads, and you are willing to pay small per-call USDC fees. Free delayed samples let you judge the data before paying.
Requirements: Either the remote endpoint (recommended, no install) or the local npm package run with npx on Node.js. Live data needs a credit key sent as an Authorization Bearer header, bought with an on-chain payment; the local package can instead use the LOSBETO_PRIVATE_KEY environment variable holding an EVM key with USDC on Base. No signup or API key is required for free tools.

Before you install

Paid tools settle automatically in USDC on Base, Solana, Algorand or Polygon, so real money is spent per call; the exact price appears in the tool's 402 challenge before payment. The local package asks for an EVM private key in LOSBETO_PRIVATE_KEY, which controls funds — prefer the remote server with a credit key. Some tools push data to a webhook you supply.

Installation

In SourceWeft

Open Losbeto in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

losbeto-mcp

Losbeto x402 market intelligence as native tools in Claude Desktop, Claude Code, or Cursor. Base chain reads with ML on top, ERC-8004 agent reputation, Brazil central-bank macro, multi-oracle price consensus, launch risk, forex, commodities and crypto — plus an OpenAI-compatible LLM gateway. No signup. No API key. Paid tools settle automatically in USDC via x402 — on Base, Solana, Algorand or Polygon.

Registered ERC-8004 agent: agentId 87048 on Base.

Recommended: remote server (no install)

The remote server exposes 5 meta-tools that cover the whole 120-endpoint catalog:

search_market_data — FREE. Describe what you need in plain language; get matching endpoints with price and parameters
get_market_data — fetch any endpoint (delayed sample FREE; live data at the endpoint's x402 price, from $0.001)
market_snapshot — one call for a whole area: brazil, global or crypto
list_categories — FREE. Every category, endpoint count, cheapest price
account_status — FREE. Subscription/credit status for this connection

Without a key, free tools work and every paid tool returns a real but delayed sample at no cost — enough to judge the data before paying. For live data, add a credit key:

json

{  "mcpServers": {    "losbeto": {      "url": "https://api.losbeto.xyz/mcp",      "headers": { "Authorization": "Bearer <credit-key>" }    }  }}

{  "mcpServers": {    "losbeto": {      "url": "https://api.losbeto.xyz/mcp",      "headers": { "Authorization": "Bearer <credit-key>" }    }  }}

Get a credit key with one on-chain payment — Base, Solana, Algorand or Polygon, your choice: POST https://api.losbeto.xyz/buy-credits (plans from $0.99 with bonus balance; machine-readable at GET /plans).

Chain intelligence + agent-native endpoints (all reachable through the meta-tools above):

Endpoint	Price	What you get
`/chain-block`	$0.001	Latest Base block: number, age, gas-used %, base fee
`/gas-price`	$0.001	Gas now + ML forecast ~10 min ahead (self-fed Holt smoothing) with send/wait recommendation
`/chain-balance`	$0.002	ETH + ERC-20 balances, nonce, wallet-class heuristic
`/chain-ens`	$0.002	ENS forward and reverse resolution
`/chain-tx`	$0.002	Tx status/value/fee/logs, optional LLM explanation (`explain=1`)
`/agent-reputation`	$0.010	On-chain ERC-8004 identity + aggregated reputation for any registered agent
`/wallet-verdict`	$0.020	Graded wallet verdict + LLM roast, idempotent, with shareable SVG card
`/x402-watch`	$0.050	Watch any third-party x402 endpoint for 30 days — price/availability changes pushed to your webhook

{  "mcpServers": {    "losbeto": {      "command": "npx",      "args": ["-y", "losbeto-mcp"],      "env": { "LOSBETO_PRIVATE_KEY": "0x..." }    }  }}

LOSBETO_PRIVATE_KEY = an EVM private key holding a little USDC on Base (optional — free tools work without it). For Solana, Algorand or Polygon payments, use the remote server with a credit key instead.

The npm package exposes the classic 9-tool set:

FREE: try_samples (6 live samples in 1 call) · welcome_free_call (one real-time call, no wallet) · launch_risk_preview · receipts (audit our on-chain sales, honestly labeled)

PAID via x402: launch_risk_brief · br_macro (BCB data) · oracle_consensus · fear_greed · sol_price — the exact current price always comes in the tool's own 402 challenge before you pay (typically $0.01–0.10).

For the full catalog (including the chain reads, ERC-8004 reputation and /x402-watch), use the remote server — the npm package is the classic fixed tool set.
