X402 Data Gateway is an MCP server with 24 tools an agent can call, among them agent_discoverability_audit, agent_surface_budget_audit, contract_qualified_search. It answers at https://agents.samedaydesk.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Paid x402 and MPP tools for agent discovery, payment safety, data, and DeFi.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
agent_discoverability_audit | Measure one service's brand-blind rank, source-family coverage, expected-route presence, canonical-vs-alias listing identity, duplicate records, competitors, and exact-price drift across ten public machine-service discovery views. Supply `r Inputs: origin, intent, route, method, runtimeUrl, payTo |
agent_surface_budget_audit | Measure one public service's credential-free MCP tools/list, OpenAPI, or both declared discovery surfaces before any tool call or target payment. Use `agent_discoverability_audit` for catalog reach and rank, `seller_integrity_audit` for one Inputs: origin, surfaceMode, mcpPath, openApiPath, mcpBudgetBytes, openApiBudgetBytes |
contract_qualified_search | Search Agent402 and the official MPP catalog for paid machine services that both match a capability intent and guarantee buyer-required JSON response paths. Use `agent_discoverability_audit` when you are measuring one known seller's catalog Inputs: query, requiredPaths, maxPriceDisplayUnits, limit |
deep_audit | Run one read-only AI-search-readiness audit for a public business domain: company, technology, contact, and DNS/email evidence from `enrich`, plus the live structured-data gap analysis and paste-ready JSON-LD template from `schemaforge`. Us Inputs: domain, vertical, city |
enrich | Inspect a public company domain and return structured identity, technology, social, contact, DNS, email-infrastructure, and AI-readiness evidence. Use `schemaforge` instead for a paste-ready JSON-LD template and remediation diff, or `deep_a Inputs: domain |
extract | Fetch a public HTTP(S) page and return compact extraction signals for programmatic inspection: title, meta description, Open Graph/Twitter metadata, JSON-LD, headings, links, text excerpt, and AI-readiness flags. Use `read` instead when you Inputs: url |
extract_batch | Fetch one to five public HTTPS URLs and return bounded structured fields for each source in one paid attempt. Supply `urls` as a JSON array and optional unique `fields`. Use `extract` for a single URL when you do not need batch accounting. Inputs: urls, fields |
lockfile_pin_delta | Inspect two caller-supplied npm package-lock.json objects and return added, removed, and changed name+version+integrity+resolved pins. Supply JSON `before` and `after` lockfile objects, not filesystem paths, URLs, or commands. An identical Inputs: before, after |
morpho_market_underwrite | Underwrite one Base Morpho market with independent GraphQL, REST, and direct-RPC evidence for configuration integrity, liquidity, utilization, concentration, borrower health bands, recent history, bad debt, and PreLiquidation availability. Inputs: marketId |
morpho_position | Inspect one Base borrower across Morpho markets and return position balances, LTV, health factor, liquidation headroom, direct-RPC verification, and caller-selected collateral-price stress scenarios. Use `morpho_protection` when you need ex Inputs: address, shocks |
morpho_preliquidation_replay | Reconstruct one successful Base Morpho PreLiquidation transaction from its receipt and the exact block state, returning repaid and seized assets, protocol-oracle valuation, gross incentive, configured health window, and transaction gas befo Inputs: transactionHash |
morpho_protection | Calculate two alternative protection plans for one Base Morpho borrower under a selected collateral-price shock and target health factor: partial repayment or added collateral. Each plan includes the bounded asset amount, expected stressed Inputs: address, targetHealthFactor, protectAgainstShockPct, executionBufferBps |
opportunity_preflight | Agent work opportunity -> deterministic attempt, verify-first, or abandon preflight using caller-supplied cost and selection assumptions plus dated platform evidence. Returns break-even probability, expected surplus, hard gates, and source- Inputs: platform, rewardUsd, hours, hourlyCostUsd, computeUsd, mandatorySpendUsd |
payment_offer_preflight | Compare x402 and MPP payment challenges, terms, and seller-declared JSON success-response readiness for one exact public HTTPS GET route before buyer authorization, including URL and realm binding, expiry, cross-protocol economic parity, an Inputs: url, catalog |
read | Fetch a public HTTP(S) page and return its readable body as cleaned Markdown for LLM context, preserving headings, links, and lists while dropping navigation, ads, scripts, headers, footers, asides, and forms. Use `extract` instead when you Inputs: url |
scan | Static supply-chain security scan of a public GitHub repo before an agent installs/runs it. Flags exfil sinks, obfuscation, credential reads, install-time curl|bash. risk=clean|suspicious|dangerous. Inputs: repo |
schemaforge | Analyze a public business site and return a deterministic, paste-ready JSON-LD template plus the live structured-data gap diff and ranked fixes. Use `deep_audit` instead when the same call must also return company, technology, contact, and Inputs: site, vertical, city |
seller_integrity_audit | Use this after a buyer integration fails, a seller changes a paid route, or before the next paid retry or release. Audit one exact paid GET or POST seller route against buyer-required JSON success paths. GET verifies constructible non-secre Inputs: origin, route, method, requiredPaths, requireBazaar, referral |
settlement_proof | Verify one claimed canonical Base USDC settlement after execution by matching a successful transaction receipt to the exact recipient, atomic amount, and optional payer. Use `payment_offer_preflight` before authorization when you need to in Inputs: transactionHash, recipient, amountAtomic, payer |
solana_transaction_receipt | Inspect one finalized Solana mainnet transaction signature and return normalized success or failure status, slot, block time, fee, SPL-token owner deltas, and canonical USDC deltas. Supply recipient, amount, and optional payer when an exact Inputs: signature, mint, recipient, amountAtomic, payer |
stateful_wallet_policy_conformance | Evaluate safe standardized observations from wallet policies that track prior or concurrent requests. Use `wallet_policy_conformance` instead for one-request action shape, method, chain, token, recipient, amount, and function controls. This Inputs: profileId, provider, network, protocol, observations |
transaction_receipt | Inspect one Base or Ethereum transaction hash and return normalized success or revert status, block time, gas and fee fields, decoded ERC-20 Transfer events, and canonical USDC transfers. Use `settlement_proof` instead when you must verify Inputs: transactionHash, network |
wallet_enrich | Inspect a public Base or EVM address and return an agent-ready on-chain profile: EOA or contract type, native and curated token holdings, token/NFT metadata, proxy evidence, activity, and a derived profile label. Use `enrich` for a company Inputs: address |
wallet_policy_conformance | Evaluate safe standardized allow, deny, and error observations from an agent wallet or delegated signer. Use this after running a bounded provider policy test matrix to distinguish explicit provider-policy enforcement from validation or gen Inputs: profileId, provider, network, protocol, observations |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://agents.samedaydesk.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
