get_mpp32_diagnosticsReport what the mpp32-mcp-server detected at startup: version, API URL, env vars (MPP32_AGENT_KEY, MPP32_SOLANA_PRIVATE_KEY, MPP32_PRIVATE_KEY, MPP32_PREFERRED_NETWORK), and a live API connectivity check. Use this FIRST if payments fail with 'no key configured' even though you set one in claude_desktop_config.json.debug_mpp32Alias for get_mpp32_diagnostics. Reports env-var detection, API connectivity, and ready-to-pay status.list_mpp32_servicesBrowse the MPP32 federated catalog of 4,500+ machine-payable APIs and data services. Includes native MPP32 services (callable end-to-end through this MCP), x402 Bazaar services (pay-per-call in USDC, mostly on Base, some on Solana — callable when they expose an HTTPS endpoint), curated free APIs (DexScreener, Jupiter, CoinGecko health, httpbin, etc.), and the public MCP Registry (npx-installable servers; listing-only). Each result indicates whether it is callable through `call_mpp32_endpoint` or listing-only. The catalog is large (~4,500 entries) — by default a single call returns up to 100 results and the response will tell you the true total and whether the page was truncated. Use `q` (free-text search), `category`, `source`, or `protocol` to narrow down, or raise `limit` (max 500) for broader pages.find_mpp32_serviceDescribe what you need in plain language instead of browsing the 4,500+ entry catalog yourself. Returns a ranked shortlist — ranked by keyword relevance, catalog health status (broken listings are excluded automatically), verification, and whether the price actually fits your stated budget. Use this before `list_mpp32_services` when you have a task in mind ('check if this wallet is a rug', 'generate a product image', 'get real-time SOL price') rather than a category to browse. The top result's slug is ready to pass straight to `call_mpp32_endpoint`.call_mpp32_endpointCall any HTTP-callable service in the MPP32 federated catalog. Free services return immediately. Paid services return a 402 challenge that this tool will sign and retry automatically when a payment key is configured: MPP32_SOLANA_PRIVATE_KEY pays x402 USDC on Solana; MPP32_PRIVATE_KEY (one EVM key) pays x402 USDC on Base and Tempo pathUSD. The result is checked after payment — a rejected payment is reported, never shown as success. Set MPP32_AGENT_KEY for dashboard tracking. Use `list_mpp32_services` first to find a slug. Many catalog entries store only the upstream BASE URL (e.g. `https://api.exa.ai`) — pass the upstream path (e.g. `/search`) via the `path` argument when calling those. Listing-only entries (npx-installable MCP servers, etc.) cannot be called through this tool.get_solana_token_intelligenceGet real-time Solana token intelligence from the MPP32 Intelligence Oracle. Returns alpha score (0-100), rug risk assessment, whale activity, smart money signals, 24h pump probability, projected ROI ranges, and aggregated DexScreener/Jupiter/CoinGecko market data. **FREE TIER: Every agent session gets 10 free calls per day — no wallet, no USDC, no payment setup required.** Just set MPP32_AGENT_KEY. After free tier: $0.008/query, paid automatically in USDC via x402 on Solana (MPP32_SOLANA_PRIVATE_KEY) or Base (MPP32_PRIVATE_KEY), or pathUSD via Tempo (MPP32_PRIVATE_KEY). M32 token holders receive up to 40% discount.try_solana_token_intelligence_freeFREE preview of the MPP32 Intelligence Oracle — quick anonymous test, no keys required. Rate-limited to 10 calls/minute per IP. Returns the same payload as the paid endpoint. **Better option: get an MPP32_AGENT_KEY from mpp32.org/agent-console and call `get_solana_token_intelligence` instead — you get 10 FREE attributed calls per day, plus dashboard tracking, before any payment is needed.**get_m32_whale_trackerM32-gated whale analysis for any Solana token. Returns top 20 holders, concentration risk, holder distribution, and buy/sell pressure. Requires the caller to hold 1,000,000+ M32 tokens (balance verified on-chain via X-Wallet-Address header). Free for qualifying holders — no payment required. Returns 403 if the wallet holds insufficient M32.compare_tokens_m32M32-gated head-to-head intelligence comparison of two Solana tokens. Returns side-by-side alpha scores, rug risk, whale activity, volume, liquidity, market data, and a winner verdict. Requires the caller to hold 2,500,000+ M32 tokens (balance verified on-chain via X-Wallet-Address header). Free for qualifying holders. Returns 403 if insufficient M32.scan_portfolio_m32M32-gated full wallet portfolio scan. Discovers all SPL tokens in a Solana wallet, runs intelligence on top holdings, and returns per-token analysis with aggregate portfolio risk metrics. Requires the caller to hold 5,000,000+ M32 tokens (balance verified on-chain via X-Wallet-Address header). Free for qualifying holders. Returns 403 if insufficient M32.get_pivx_dao_intelligenceGet real-time PIVX DAO governance intelligence. Returns active budget proposals with masternode voting tallies (Yes/No counts, net yes percentages), budget allocation status, network deflation metrics (unallocated treasury PIV that are never minted), and masternode network health. PIVX is a fully community-governed cryptocurrency where Masternode owners vote on budget proposals every ~30 days (43,200 blocks per superblock cycle, 432,000 PIV max monthly budget). Data is served by the MPP32 backend, which aggregates pivx.org/proposals and the PIVX blockchain via Chainz CryptoID, and caches for 5 minutes. Free — no payment or API key required.manage_agent_budgetView and control the spending limits of your MPP32 agent session. 'get' = current budget status (remaining budget, hourly velocity, paused / circuit-breaker state). 'set' = configure limits (budget cap in USD, hourly velocity limit, alert threshold). 'pause' = immediately stop all paid calls (safe to use any time). 'resume' = lift a pause, and 'reset' = clear a tripped circuit breaker — ONLY use 'resume' or 'reset' when the human operator explicitly asks you to; never on your own to get past a limit, because the breaker exists to stop runaway agent spending.- +4 more on the listing page
X402 Trust MCP tools 13
x402_ecosystem_statsFree aggregate snapshot of the entire x402 ecosystem (Base + Solana): how many endpoints are listed/active/delisted, what fraction are reachable and spec-compliant, and real on-chain USDC settlement volume / receivers / payers over the last 30 days. Use this to gauge market health before transacting.x402_trust_leaderboardFree top-25 most trustworthy x402 hosts (providers), ranked by a deterministic trust score. Each host's score is the probe-weighted mean of its listed endpoints' scores, so providers are judged by their whole measured surface instead of one provider flooding the board with path variants. The per-endpoint score blends uptime, envelope compliance, latency, age, on-chain settlement activity and price stability. Latency is measured from a single EU vantage point and includes network distance to the endpoint (so it is only lightly weighted). Use this to discover reliable paid endpoints.x402_trust_previewFREE showcase of what x402_trust_score returns. You do NOT choose the endpoint: this returns the COMPLETE paid-grade trust report (every field — exact score, scoreRange, full component breakdown, advertised price, on-chain settlement figures, all flags) for THREE endpoints picked from the current population — the best-scored, the median, and the worst-scored ('samples' each carry 'role', 'populationRank', and the full 'report'). Use it to see exactly what the paid output looks like across the entire quality range BEFORE paying. It cannot score an endpoint you choose — to evaluate YOUR OWN endpoint, call x402_trust_score (paid). Takes no arguments.x402_trust_scoreTrust score (0-100, grade A-F, or '?' when unmeasured) for a SPECIFIC x402 endpoint -- cataloged or not (uncataloged endpoints are live-probed on first query, auto-adopted, score carries a low-confidence first-contact flag). PLUS a machine-readable verdict ('recommendation': proceed|caution|avoid|parameterize|unverified|not-payable|free), the advertised price ('advertised.amountUsd'), a confidence-adjusted band ('scoreRange'), and structured flags ('flagsDetailed' with code/severity/message; any severity 'error' means avoid). The 'parameterize' verdict (with 'templated':true) means the resource URL still contains an unresolved template placeholder (e.g. {slug}, :slug or %7B…%7D) but we DO have a real signal (scored probes or a discovery fallback): substitute a valid value first, then the health metrics apply to the resolved URL. The 'unverified' verdict (grade '?') means we have NO measurement at all (every probe excluded and no discovery payment requirements to fall back on): it is unknown, not bad, so verify the endpoint yourself before paying. The 'not-payable' verdict (grade '?') means the URL answers a 402 with an EMPTY accepts[] (an auth/API-key gate such as sign-in-with-x), or answers a bare 401/403 with no payment envelope, so it is not an x402-payable resource at all and there is nothing to settle. The 'free' verdict (grade '?') means the endpoint answers plain requests with data (HTTP 200, no payment envelope) and has never presented a payment challenge: a free resource with no payment flow to grade, unmeasured by design, not a negative verdict. For templated per-item endpoints that ARE payable, a varying payTo/price is EXPECTED (one wallet/price per item): the report surfaces 'stats.payToVaries'+'payToDistinct30d' and 'advertised.amountRange30d' as a 'payto-varies'/'price-varies' note rather than a 'payto-changed-recently' hijack error; always pay the payTo in the live 402 quote, not a cached listing. 'stats.scoredProbes30d' vs 'stats.excluded30d' show how many probes actually back the score. When the endpoint's host completed provider verification (domain control proven with a public key in /.well-known/x402-trust.txt plus a confirmed contact email), the report carries 'providerVerified': true, 'providerName' (the provider's own organization name) and 'providerContact' (the confirmed contact address); verified endpoints also carry the 'provider-verified' info flag; verification never changes the score. Includes the full component breakdown, the provider-advertised 'serviceName' and 'description' (unverified provider claims, shown next to our independent metrics), and 30-day on-chain stats. Note: 'stats.avgLatencyMs' is measured from a single EU vantage point and includes network distance to the endpoint (see 'stats.latencyVantage'), so a geographically distant endpoint reads slower even when its server is fast. One call answers WHETHER and at WHAT PRICE to use an endpoint. Call this BEFORE paying an unknown x402 endpoint to avoid dead, fraudulent, or recently-hijacked services. Each paid call also refreshes the endpoint's free public snapshot (page, badge, card) immediately. Pay-per-call over x402; auto-pays if a wallet is configured, otherwise returns the price quote.x402_endpoint_historyRaw observation time-series for a SPECIFIC x402 endpoint: listing/delisting/relisting events, advertised price changes, payTo changes, and probe results over the requested window (1-90 days). Each probe carries 'ts', 'ok', 'latencyMs', 'amount' plus its outcome 'status' (success, dns_error, timeout, http_error, ...), 'httpStatus', an 'error' detail and an 'excluded' flag; excluded probes carry no endpoint signal (rate limits, unresolved URL templates, resolver outages on our side) and never count as downtime. A 'probeSummary' aggregates the window: counts by status, longest failure streak, per-day failure breakdown. Per-probe 'latencyMs' is measured from a single EU vantage point and includes network distance to the endpoint. Pay-per-call over x402; auto-pays if a wallet is configured, otherwise returns the price quote.x402_find_alternativesGiven an x402 endpoint URL, returns the top semantically-similar endpoints (matched on advertised purpose via description embeddings) that currently OUT-SCORE it on the deterministic trust score. Use this to route away from a mediocre/dead/expensive endpoint toward a more reliable, better-settled one serving the SAME function — e.g. before paying, check if a higher-graded equivalent exists. Each alternative carries its trust 'score', 'grade', 'recommendation', cosine 'similarity' (0-1), 'amountUsd' price, 'priceCeiling' (true when amountUsd is an x402 'upto' authorization ceiling, not a fixed per-call price), and a free 'endpointPage' URL. It also carries 'hasDescription': false means the endpoint advertises no description, so its similarity was computed from service name + URL path tokens only, a weaker signal worth more skepticism than a description-based match. Same-host siblings and 'avoid'-flagged endpoints are excluded. An empty 'alternatives' array is a valid answer meaning nothing beats the subject. Similarity is independent of latency/geography. Pay-per-call over x402 (~$0.005); auto-pays if a wallet is configured, otherwise returns the price quote.x402_semantic_searchFree-text SEMANTIC SEARCH across the entire monitored x402 endpoint catalog. Given a plain-language query (e.g. "weather forecast", "image generation", "EVM gas price oracle"), returns the up to 25 endpoints whose advertised purpose is semantically closest. Ranking is deterministic and fully specified: cosine similarity bucketed to whole percentage points first (80.3% and 80.5% are the same bucket, so sub-percent noise never outranks a better endpoint), then trust score (0-100), then described-before-undescribed, then endpoint id as a stable final tiebreak. Matches below a 0.5 cosine-similarity floor are dropped entirely, so a query can return fewer than the requested limit (or none). Endpoints that advertise no description are still matched: they are embedded from their service name and URL path tokens instead of a written description (host name as a last resort). The EXACT effect of a missing description: no fixed point deduction, and no direct similarity malus either; the only deterministic penalty is the described-before-undescribed tiebreak (at equal similarity bucket AND equal trust score, a described endpoint ranks first). Beyond that the effect is purely indirect: the shorter fallback text typically yields lower cosine similarity than a prose description, so undescribed endpoints tend to land in lower similarity buckets, by a query-dependent (never fixed) amount. Use this for DISCOVERY: find candidate endpoints for a capability before checking any of them in depth. Each match carries 'id', 'resource' URL, trust 'score' (0-100), 'grade' (A-F), raw cosine 'similarity' (0-1; ranking buckets it to whole percents), 'amountUsd' price (null when not advertised), 'priceCeiling' (true when amountUsd is an x402 'upto' authorization ceiling, not a fixed per-call price), 'description' when advertised, and a free 'endpointPage' URL. 'score'/'grade' are null for endpoints not yet scored. Deliberately NO verdict/recommendation or flag detail: the per-endpoint trust report (x402_trust_score) carries those. Pay-per-call over x402 (~$0.001); auto-pays if a wallet is configured, otherwise returns the price quote.x402_trust_bulkScore up to 500 x402 endpoints in a SINGLE paid call. Returns the authoritative full-density trust score (0-100, grade A-F or '?' when unmeasured, recommendation proceed|caution|avoid|parameterize|unverified|not-payable|free), confidence, `probed_at`, `computed_at`, and a `recomputed` flag for each requested resource. Cache rows older than ~15 minutes are recomputed on-demand from the latest stored probes and settlements (no live network re-probe), so bulk scores typically reflect reality within minutes. Each recomputed row also refreshes that endpoint's free public snapshot (page, badge, card) immediately. Per-request recompute limits apply: at most 50 endpoints / 8 seconds are recomputed; the response includes `recompute_limit_hit` and `recompute_limit` so you know if the cap was reached. The smallest tier that fits your request is selected automatically (10/50/100/200/500 endpoints; ~$0.045/$0.20/$0.325/$0.40/$0.50). Resources not in our observation set return `found:false`; you still pay for the batch. For a fresh live probe, use `x402_trust_score`. Pay-per-call over x402; auto-pays if a wallet is configured, otherwise returns the price quote.x402_watch_createStart monitoring ONE x402 endpoint for 30 days. Get alerted on changes that break autonomous payment: payTo changes (possible takeover/rug — but for a templated per-item endpoint a payTo move is expected variance and is delivered as severity 'warn', not 'critical'), price changes, asset/network changes, 402-spec regressions, delisting, and liveness down/recovered. A self-healing endpoint that repeatedly blips is auto-detected as `liveness_flapping` and its individual down/up alerts are coalesced into a single flapping notice (plus one 'stopped flapping' notice when it stabilizes) so you are not spammed. Returns a one-time bearer secret + poll URL + renew URL + edit URL + cancel URL + machine-readable `next_steps`. Use x402_watch_events to poll the append-only log, or configure push delivery to one or more signed HTTPS webhooks and/or Slack/Discord incoming webhooks (max 5 each). `webhook_url`/`slack_url` accept a single URL string or an array of URLs. All URLs are connection-tested BEFORE payment — unreachable URLs are rejected with no charge (retry with a corrected URL). On success the response reports per-URL delivery in `delivery.connection_test`. Webhook signature: `x-signature` = 'sha256=' + HMAC-SHA256(body) keyed by hex(sha256(secret)), NOT the raw secret. Pay-per-call over x402 (~$0.20); auto-pays if a wallet is configured, otherwise returns the price quote.x402_watch_eventsRead the append-only event log for an active x402 watch. Returns two streams: `events` (endpoint changes — payTo/price/asset/spec/delisting/liveness) and `watch_events` (lifecycle feedback — created/edited/cancelled/renewed/expiring/expired). Nothing between two polls is lost. Provide the watch_id and the one-time secret from x402_watch_create. Advance `since` with the returned `next_cursor` (endpoint events) and `watch_since` with `watch_events_cursor` (lifecycle events). Cursors/ids are GLOBAL sequences shared across watches (a watch's first event id may be >1); always page by the returned cursor rather than assuming they start at 1. Cancelled watches remain READABLE until expires_at (no new events accrue). If the watch has push delivery, still poll to reconcile missed webhooks.x402_watch_editEdit an active watch: change webhook/Slack URLs, liveness sensitivity, or subscribed events. Bearer-authed with the secret from x402_watch_create. Newly-added URLs are connection-tested before the change is persisted; if any new URL fails, the existing config is unchanged. Delivery fields are full-replace per channel (omit to leave that channel unchanged). Returns the updated watch view.x402_watch_cancelSoft-cancel a watch immediately: no new events accrue, but the event log stays READABLE via x402_watch_events until the original expires_at (cancel is not a delete). Probing drops back to normal cadence as soon as no active watches cover the endpoint. Bearer-authed with the secret from x402_watch_create. Free and idempotent.- +1 more on the listing page
