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 List MCP tools 7
x402_search_servicesYour first call when you do not know which x402 service exists for a job: it narrows a directory of 500+ listed services to candidates. Filter by free-text query, category, network, live status, and whether the last observed 402 envelope is signable by a standard x402 client; sort by newest, uptime, cheapest, or endpoints. Returns up to 100 compact summaries a page: price in decimal USD, uptime, status, verification. Then x402_get_service for the full record.x402_get_serviceCall this once you hold a slug and are deciding whether to commit to that service: the full record behind a directory row. Live status, uptime over 24h/7d/30d/90d, average response time, networks and settlement asset, every priced endpoint, and the assessment block. include_series=true adds 90 daily points of on-chain volume and distinct buyers. Read the units map in the response: the per-endpoint price field is atomic token units, not dollars.x402_find_best_serviceCall this when you have a need in words and want one service to call rather than a list to read: it is the free ranking step between searching and paying. Pass the need as q, plus any category, network, price cap or verification requirement, and get up to 20 ranked recommendations with the basis each one placed on. Ranking is mostly per-service reliability (live status, verification, uptime, response time), x402 compliance, and price in USD, with a small (about 10%) weight on measured on-chain settlement traction that can never dominate those three. The response carries ranking_version (currently 3), need_blind_ranking (true when no q was given, so the order is global quality rather than your need), and a units map holding every scoring caveat in full: the compliance cap, the pro-quota rule for shared payout addresses, renormalization, the $10 volume floor, and the single-buyer discount. Read units before comparing scores across generations.x402_check_healthCall this before you send a payment, or right after a call unexpectedly failed: is this service up right now. With no slug, the directory snapshot: five status counts across 500+ services (include_services=true attaches every row). With a slug: that service's status, its 24h/7d/30d/90d uptime windows, response time, consecutive failures, daily snapshots. No money fields.x402_facilitator_volumesCall this when the question is about the rail rather than the service: which x402 facilitator actually settles money, and how much. Returns on-chain-verified settlement volume and transaction counts per facilitator for today (UTC), 7d, 30d and all-time, plus a verification flag ('on-chain' once volume has been observed on-chain, else 'listed'), across more than 30 facilitators. Optional daily timeseries (up to 90 days) and per-chain breakdown. Volume is decimal USD. Caveats: PER-FACILITATOR, never per-service; the *_24h fields cover today (UTC) so far, not a trailing 24 hours, and reset at 00:00 UTC, so prefer 7d.x402_assess_servicesCall this when the free signals have run out: you hold 2 to 8 finalists from x402_search_services or x402_find_best_service, their stored fields do not separate them for YOUR stated need, and choosing wrong costs more than a quarter. It buys one fresh AI assessment reasoned against your question, not a cached grade; reading an already-computed assessment stays free via x402_get_service. Price: a one-time $0.25 USDC on Base, over two calls. Call once WITHOUT payment_signature_b64 to receive the x402 payment challenge verbatim (accepts[], amount, payTo, and a base64 PAYMENT-REQUIRED header); sign accepts[0] client-side with your own wallet; call again with the SAME question and services plus payment_signature_b64 to receive the report and a base64 PAYMENT-RESPONSE settlement receipt. This server holds no keys, never signs and never settles: it only relays the challenge. Optionally add probe { slug, endpoint_path? } to have one listed service paid and called for real and its answer analyzed: the challenge is then priced at $0.25 plus that endpoint price X, and the report gains a probe_report block with a verdict and truncated extracts, never the verbatim third-party body. When live probing is not armed the probe is ignored. Caveats: read the amount to sign from accepts[0].amount, never from a fixed figure, since a probe changes it; probe fees are non-refundable whatever the verdict; if the fresh run cannot be produced the server answers before settling, so you are never charged for nothing; there is no refund. Prices are US dollars.x402_change_eventsCall this before you trust anything you cached about a service, and right after a payment failed for no obvious reason: the monitor's log of what moved under you. Returns payTo, price and 402-schema changes observed on listed services, most recent first, in exactly three event types (payto_changed, price_changed, schema_changed). Filter with service (the slug), type, and days (1 to 365, default 90). Caveats: prices here are atomic token amounts, never dollars, and every payTo is masked by design, so the feed reports THAT the payout address changed, never the address. Free and read-only.
