VerifiedSTDIODesktop onlyWeb Search & ScrapingFinanceAI & ML

Overview

AI-generated overview

Local MCP server that gives an assistant pay-per-call access to LLM inference, web/SEO tools and on-chain token safety checks, paid in USDC on Base via x402.

What you can do
  • Run LLM chat completions and list models with live per-token pricing
  • Fetch and extract web pages, link previews, screenshots, robots/llms.txt policy and HTTP security headers
  • Audit SEO/GEO, SERP results, backlinks, keyword volumes, ranked keywords and keyword ideas
  • Check ERC-20 and Solana tokens for rug/honeypot risk, address safety, deployer reputation, new pairs, liquidity pulls, whale swaps and pre-sign transaction checks on Base, Ethereum and BSC
  • Run finance calculators, search prediction markets and rank DeFi yields
When to use it
Useful when an agent needs metered access to many unrelated capabilities without signing up for each provider, especially crypto trading agents that want token-safety and pre-trade checks, or SEO and web-research workflows. Not needed if you only want free tools or do not want an agent spending from a wallet.
Requirements
Node.js 20 or newer; runs locally over stdio via npx. Optional WALLET_PRIVATE_KEY for a funded Base wallet holding USDC (gas is sponsored) to auto-pay; without it paid tools only return the 402 requirements. Optional SERVER_URL, MAX_PAYMENT_USDC and X402_ALLOW_NETWORKS settings. Network access to the true402 API.
Before you install
The server holds a wallet private key in WALLET_PRIVATE_KEY and signs real USDC payments automatically, so use a dedicated low-balance wallet. Tools are auto-discovered from a live catalog, so new or repriced paid tools can appear; calls above MAX_PAYMENT_USDC are refused. Overpayment is never refunded, and seo_audit is priced per page. Requests and URLs go to the third-party true402 service.

Installation

In SourceWeft

  1. Open True402 in the dashboard and add it to a workspace.
  2. 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.

@true402.dev/mcp-server

MCP server for the true402 machine-native marketplace — give your agent pay-per-call access to AI inference and web tools over x402 (HTTP 402 micropayments in USDC on Base).

No accounts, no API keys. The agent's wallet is its identity: each paid tool returns an HTTP 402 challenge, the server signs an EIP-3009 USDC authorization, and the call settles on-chain. Configure a funded wallet to auto-pay, or run without one and the paid tools will surface the exact payment requirements instead of failing.

Tools

Tools are auto-discovered from the live catalog at startup, so a new marketplace stall appears without an update to this package. The catalog currently yields:

Prices are indicative; the live 402 challenge is authoritative, and the server refuses to sign above its per-call cap. Call list_models or read https://true402.dev/api/openapi.json for the exact set.

Install

Requires Node.js ≥ 20. Runs over stdio — point any MCP client at it via npx.

Claude Desktop / Claude Code

Add to your MCP config (claude_desktop_config.json, or .mcp.json for Claude Code):

json
{  "mcpServers": {    "true402": {      "command": "npx",      "args": ["-y", "@true402.dev/mcp-server"],      "env": {        "WALLET_PRIVATE_KEY": "0xYOUR_FUNDED_BASE_WALLET_KEY"      }    }  }}

Cursor / Cline / other MCP clients

Same idea — command npx, args ["-y", "@true402.dev/mcp-server"], and the WALLET_PRIVATE_KEY env var.

Configuration

Env varDefaultDescription
SERVER_URLhttps://true402.dev/apitrue402 API base. Override to point at a self-hosted instance.
WALLET_PRIVATE_KEY(none)A funded Base wallet private key used to sign x402 payments. Needs USDC (gas is sponsored by the facilitator — no ETH required). Without it, paid tools return the 402 requirements instead of paying.
MAX_PAYMENT_USDC0.25Hard per-call spend ceiling in USDC. This server auto-discovers every paid stall the marketplace advertises (it walks the live OpenAPI spec, not a fixed list), so a new or repriced stall can appear above the default at any time — a call over the ceiling is refused (not paid, not crashed), and the refusal names the price and the ceiling. Raise it if a discovered tool's description shows a price close to or over your configured value; one stall (seo_audit) is priced per page and can itself exceed a typical ceiling on a large page.
X402_ALLOW_NETWORKS(none)Payments are signed for Base mainnet (eip155:8453) only; a 402 naming any other chain is refused. To also pay on Base Sepolia or Ethereum mainnet, list them as comma-separated CAIP-2 ids, e.g. eip155:84532,eip155:1. Unsupported entries are ignored.

Security: the key is read only from the environment and is never logged, echoed, or returned. Use a dedicated low-balance wallet — fund it with only what you intend to spend.

How payment works

  1. The tool calls the true402 endpoint with no payment.
  2. The server replies 402 with accepted payment options (USDC on Base).
  3. This MCP server signs an EIP-3009 transferWithAuthorization with your wallet.
  4. It retries with the signed payment in the PAYMENT-SIGNATURE header (x402 v2); the service verifies and responds.
  5. Settlement happens on-chain. Your wallet pays only USDC — the facilitator sponsors gas.

When a newer release of this server exists, the first tool result of the session carries one extra line saying so, with the install command. Nothing is blocked; it is shown once per process.

Paying, exactly

The rules below are the service's, not this package's — they bite whatever client you use, and they are the ones that surprise people writing their own payer.

  • Pay the EXACT amount quoted in the 402. Underpaying is rejected. Overpaying is refused with 402 and never credited — settlement submits the signed value and there is no refund path, so a surplus would simply be swept. Equality is also what binds an authorization to the resource it was quoted for.
  • One authorization buys exactly one response. A replay is refused, not double-charged.
  • You are charged on success only. Settlement is submitted only when the endpoint returns 2xx; if it errors or times out, your signed authorization is never submitted, so there is nothing to refund.
  • Some endpoints serve a few free calls per day per client IP, with no wallet. The per-operation description in the OpenAPI spec says which.

list_models

List every LLM model available through true402's pay-per-call inference, with live per-token pricing (3% over provider cost, min $0.0001/request). Returns each model's id, provider, and input/output token prices across OpenAI, Anthropic, Google, Groq, Mistral and Together — so an agent can pick a model and know the exact cost before paying via x402 (USDC on Base, no account or API key).

Takes no parameters.

chat

Send a chat completion request to an LLM via true402 (PAID x402 service, USDC on Base). Requires a funded wallet (WALLET_PRIVATE_KEY) on the MCP server.

Parametersurlrequired

token_safety

Rug/honeypot safety check for an ERC-20 token on Base (from on-chain reads — no API key): ERC-20 conformance, ownership renounce, mint-capability, WETH/USDC liquidity depth across Uniswap V3 + Aerodrome, and a buy/sell honeypot simulation (a gas-free eth_call that round-trips a tiny WETH→token→WETH trade to detect tokens you can buy but not sell). Returns a 0–100 score + risk flags. POST `{ token }`. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.005 USD (fixed).

Parameterschaintokenrequired

new_pairs

Recently-created Base DEX pairs (Uniswap V3 + Aerodrome) from a background log-watcher — fresh token launches for trading agents/snipers. POST `{ since?, limit?, dex?, withToken? }`; each pair gives the new token, quote (WETH/USDC), pool, fee|stable, block + approx age. Bundle with /v1/token-safety for a pre-trade rug/honeypot check. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.003 USD (fixed).

ParametersdexlimitsincewithToken

liquidity_pulls

Liquidity-pull / rug alerts on Base — Burn (liquidity-removal) events on recently-launched DEX pools (the new-pairs watcher's set). POST `{ since?, limit?, dex?, minQuote? }`; each event gives the pool, token, and WETH/USDC amount removed (the rug magnitude). Cross-check the token with /v1/token-safety. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.003 USD (fixed).

ParametersdexlimitsinceminQuote

liquidity_history

Observed liquidity history for a Base token, from our own DEX archive. POST `{ token, limit? }` returns every pool we have indexed for it, every liquidity-removal event with the amount removed, block and transaction hash, and the other tokens drained in the SAME transaction (one actor, several pools). Unlike a live honeypot simulation this answers what ALREADY happened — a pool drained last month simulates fine today if it was re-seeded. Every answer carries `coverage`, the exact block range our removal index covers, so an absence of removals is never presented as a clean bill of health. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.005 USD (fixed).

Parameterslimittokenrequired

tx_preflight

Check a Base transaction BEFORE signing it. POST an UNSIGNED transaction `{ from, to, data?, value? }` and get three independent lenses: simulation against current state (does it revert?), decoded intent (is this an unlimited approval that outlives the trade?), and the counterparty liquidity-removal history from our own archive. Takes NO private key and NO signature, so the service cannot broadcast or front-run the transaction it inspects — a deliberate security property. It never returns "safe": a clean result means these checks found nothing, and the `limits` array says so in every response. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.008 USD (fixed).

Parameterstorequireddatafromrequiredvalue

whale_swaps

Recent large ($-value) DEX Swap events (Uniswap V3 + Aerodrome) on the Base pools the new-pairs watcher tracks — a whale-following / copy-trading signal. POST `{ min?, dex?, since?, limit?, direction? }`; each swap gives the pool, token, quote (WETH/USDC), USD size, direction (buy/sell of the token), block + approx age, txHash. usdValue is the quote side (WETH×ETH-USD or USDC). Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.005 USD (fixed).

Parametersdexminlimitsincedirection

token_dossier

Everything we know about a Base ERC-20, in one call. Contains the full Token Report (ERC-20 conformance, ownership, mint-capability, liquidity depth, buy/sell honeypot simulation, live rug + whale activity, avoid|caution|ok verdict) PLUS two sections the cheaper report cannot carry: the deployer's reputation (wallet age, prior deployments) and the durable liquidity archive for this token (every pool, every removal with amount/block/tx, and the other tokens drained in the SAME transaction — operator linkage). Those two are what distinguish a bad token from a serial rugger. Each section reports its own status and `limits[]` names what could NOT be established, because a silently missing section reads as reassurance. The verdict is inherited from the Token Report and may only be escalated, never softened. POST `{ token }`. No free trial on this stall. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.1 USD (fixed).

Parameterschaintokenrequired

token_report

The flagship composite for a Base ERC-20 — one call instead of five. Runs the full token-safety check (ERC-20 conformance, ownership, mint-capability, WETH/USDC liquidity depth, buy/sell honeypot simulation), enriches it with the live recent liquidity-removal (rug) + whale-swap activity on the token, and returns a single avoid|caution|ok verdict with reasons plus the underlying reports. POST `{ token }`. Cheaper than buying token-safety + liquidity-pulls + whale-swaps separately. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.008 USD (fixed).

Parameterschaintokenrequired

address_safety

Structural safety profile for ANY Base address — an EOA or an arbitrary contract — before an agent sends funds to it, approves it, or calls it. Returns contract-vs-EOA, ETH + USDC balance, tx-count (activity), and for contracts: whether it is a recognised ERC-20, ownership state, a mint() selector, and whether it is an EIP-1967 upgradeable proxy (its logic can be swapped after you trust it). Coarse risk band + flags. On-chain reads only — no API key. POST `{ address }`. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.005 USD (fixed).

Parameterschainaddressrequired

deployer_check

Resolves the deployer of a Base token and profiles that wallet's reputation: age (tx-count), balance, and whether it is a FRESH throwaway spun up for the launch (a common rug setup) — the discriminating caution. Reputation context a structural/honeypot check can't see. The creator is resolved from the chain itself (its creation receipt), so no explorer is needed. On Base the contracts-shipped count and deep mode are unavailable for now: both need an explorer's list of the contracts a wallet created, which Base lacks today, so contractsCreated comes back null and the answer's `limits[]` says so. POST `{ token }`. Unpaid returns 402 — no free trial on this stall, it is paid from the first call. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.008 USD (fixed).

Parametersdeepchaintokenrequired

Returns a 0–100 score + risk flags. POST `{ token }`. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402.

Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402.

Parameterschainaddressrequired

token_safety_solana

Rug/trap safety check for a Solana SPL or Token-2022 token: mint authority (supply inflation), freeze authority (the Solana honeypot — the issuer can freeze your token account so you cannot sell), Token-2022 extensions (permanentDelegate = tokens can be moved out of your wallet, transferHook = issuer code can reject your transfer, transferFee) and pool liquidity depth. Returns a 0–100 score + risk flags. POST `{ token }` with a base58 mint. NOT a buy/sell simulation: Solana has no EVM bytecode, so the eth_call round-trip the Base/Ethereum/BSC stalls run does not exist here.

Returns contract-vs-EOA, ETH + USDC balance, tx-count (activity), and for contracts: whether it is a recognised ERC-20, ownership state, a mint() selector, and whether it is an EIP-1967 upgradeable proxy (its logic can be swapped after you trust it). Coarse risk band + flags. On-chain reads only — no API key. POST `{ address }`. Unpaid: free while the caller's IP has free-trial calls left that day (a small daily allowance shared across the trial stalls, no wallet); otherwise returns 402. (PAID x402 service — USDC on Base; the MCP server needs a funded wallet to settle.) Price: $0.005 USD (fixed).
