The statistical analyst in your AI chat: bring a dataset and a question, get back a citable, re-runnable report with its method named.

MCP Analytics is a Model Context Protocol server that answers business and statistical questions about your data, as deep as each question needs. - Answer: a quick question about the data, read from all of it, shown with how we got it, and saved. - Analytics: a tested statistical method runs on the data, and we interpret it with charts and a written report. - Custom Analytics: a question only your business asks, built for your data from proven models, yours to re-run on next month's file. Analytics is repeatable: same data, same numbers. Every report names its method and the code that ran it, and runs again on new data. Start with the path_resolver tool. It is for business and statistical questions about data, not a general-purpose assistant.

Non-custodial value router for humans and AI agents. Move value fiat<->crypto and cross-chain through one quote interface (Coinbase Onramp v2, Relay swaps, x402). The platform routes value; it never holds funds.

OnRamperX is a non-custodial value router for AI agents and humans — the one MCP tool to onramp fiat to crypto, offramp crypto to fiat, swap any token across 80+ chains, and settle agent payments. - Onramp: buy USDC on Base with a US debit card / Apple Pay / Google Pay (Coinbase Headless Onramp v2), human-in-the-loop for the fiat tap. - Swap & bridge: convert ETH, SOL, USDT, or any token on any chain into USDC on Base in one signature via Relay (~2.7s median, cross-chain, gas-abstracted), earning claimable app fees. - Agent payments (x402): pay-per-call settlement in USDC on Base via the Coinbase CDP facilitator, listed in the x402 Bazaar. AP2 / a2a-x402 aligned. - Rail-selection engine: quotes every eligible rail and returns ranked, non-custodial paths with fees, ETA, KYC burden, and plain-English reasoning. - Wallets: provision a gasless, user-exportable CDP Embedded Wallet on Base. Non-custodial by design — the platform never holds funds mid-flow. Settlement centers on USDC on Base. Callable from Claude, ChatGPT, Cursor, and framework agents. Tools: get_route_quote, create_swap, check_swap, create_onramp_session, provision_wallet. Built on MCP 2025-06-18, A2A 0.3, x402 v2, OAuth 2.1 (RFC 9728 PRM + RFC 8414 + RFC 7591 DCR + PKCE-S256) with a client_credentials PAT for framework agents.

Schedule, validate and publish social posts to 12 networks; every post is rule-checked first.

Check if your MCP server is ready to publish on the MCP Registry, Smithery, or npm. Preflight validates your server's actual artifacts — `server.json`, `package.json`, `smithery.yaml` — against the documented requirements of each directory. Every finding includes the evidence found, the directory rule it maps to, and the exact fix. ## What it checks - **MCP Registry** — server.json schema, name format, packages/remotes config, transport type, npm mcpName ownership, PyPI README marker - **Smithery** — Streamable HTTP transport, public HTTPS endpoint, server-card presence - **npm** — name, version, entry point (bin/main) Each finding is tagged with evidence level (`verified_from_artifact` or `inferred`), rule type (`hard_requirement`, `directory_convention`, or `heuristic`), and a source URL linking to the directory documentation. ## How to use Call `check_publish_readiness` with raw artifact contents (all fields optional): - `manifest` — your server.json - `package_json` — your package.json - `smithery_yaml` — your smithery.yaml - `pyproject_toml` — your pyproject.toml - `readme` — your README - `target_directories` — optional array of `mcp_registry`, `smithery`, `npm` Returns a verdict (`checks_pass`, `fixable`, or `not_ready`), per-directory readiness, and evidence-backed findings with concrete fixes. Zero dependencies. No LLM calls. No authentication. No PII collection.

Hosted MCP server for Preflight (https://preflight.social), a social media scheduler that checks every post against each network's real publishing rules before it leaves. Schedule, validate and publish posts to 12 networks: YouTube, TikTok, Instagram, Facebook, Threads, LinkedIn, Pinterest, Bluesky, Mastodon, Telegram, Discord and Tumblr. validate_post is a dry run of create_post, so an assistant can find out what a network would refuse before anything is sent. Auth: OAuth 2.1 with PKCE, or an API key as a bearer token. Publishing is its own scope (posts:publish); without it an assistant can only draft. MCP, API and webhooks are on every plan, Free included. Docs: https://preflight.social/docs/mcp

Health and quality monitoring for the MCP ecosystem. Check any server's reliability before your agent depends on it. Preflight monitors 18,000+ MCP servers every 10 minutes, tracking uptime, latency, schema stability, and description quality. Three tools: - **preflight_check** — real-time health status, latency, uptime, and quality score for any MCP server - **preflight_leaderboard** — the most and least reliable servers this week - **preflight_schema_changes** — what changed in a server's tool schema and when Why use it: agents that call unreliable tools fail silently and waste tokens. A one-call preflight check prevents that. Think of it as SSL for tool calls — verify before you trust.

Check if your MCP server is ready to publish on the MCP Registry, Smithery, or npm.

Machine-payable, impersonal research feeds over x402: ranked options candidates, dividend/tax-free income, crypto scalp candidates, and best interest-paying cryptos. Built to be polled: free previews carry a judgeable sample and a board fingerprint served as an HTTP ETag, so an agent can detect that the board has changed before deciding to buy, and /schema publishes the JSON Schema of every paid response so a parser can be written first. The full feed settles in XRP/RLUSD (XRPL) or USDC (Base/Arbitrum/Polygon). Not investment advice.

Pay-per-call French & European company data (official registers: INSEE Sirene, INPI RNE, NBB, Zefix and 8 more, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension), settle it in USDC or EURC on Base and send the signed PaymentPayload back on the same task. No account, no API key. Free text is not interpreted.

Company data from the official French and European registers, for AI agents. 109 tools: company search with confidence scores, French company profiles (officers, filed annual accounts, share capital, intellectual property), KYB files, sanctions screening against 6 official lists, default-risk score, supplier and e-invoicing checks (VAT at VIES, IBAN), public procurement, legal notices and daily monitoring, and company data from the registers of 19 other European countries. Pay per call, from $0.002 to $1 depending on the route. Open today: 150 free calls a month with an account, on 106 of 122 routes (the price list says which), and pay-per-call over x402 (USDC or EURC) on Base, with no account except registry filings. Prepaid credits: card top-up is not open yet. An error is never charged. Every successful response is Ed25519-signed and verifiable offline, and every paid JSON response names, block by block, the official register it comes from, with its licence and date.

Trust-first, machine-payable Solana DeFi intelligence. Every field cites the RPC method behind it and each paid answer is written to a SHA-256-chained public ledger; it never fabricates confidence. Priced per call in USDC over x402 — no account, no API key.

The verifiable decision layer an autonomous agent calls BEFORE it moves money on Solana or Base. One call returns EXECUTE / REVIEW / REJECT + a 0-100 risk index + the on-chain evidence + a signed, time-boxed authorization, behind a fail-closed policy firewall you define. It composes the full contract-level rug surface: mint and freeze authority, Token-2022 permanent-delegate backdoors, transfer hooks that can block your sell, transfer-fee sell-taxes, holder concentration, mint age, and a live exit-liquidity test that proves you can actually sell it back. Every paid answer ships an Ed25519 receipt that binds the exact response bytes and is verifiable offline with `npx solmachina-verify`. Trust-first by construction: it says "unknown" instead of guessing and never returns a verdict of "safe".
