Common questions
Is NAIF Gravity Diagnostic — Free MCP/API/Webhook Triage safe?
It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 32 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

NAIF Gravity — MCP & Integration Diagnostics
New look at NAIF Gravity — 30 October 2026
The NAIF Gravity storefront has a refreshed visual identity: midnight navy, copper accents and a glass-inspired homepage experience, with Arabic and English controls. Explore the updated storefront and service catalog.
مظهر جديد لمتجر NAIF Gravity: هوية كحلية ونحاسية وتجربة زجاجية في الصفحة الرئيسية، مع خيارات العربية والإنجليزية. شاهد المتجر.
This announcement covers the storefront design. Service scope, availability and current prices are stated on the relevant live service pages; the redesign does not establish new product readiness.
NAIF Gravity provides bounded diagnostics and repair workflows for MCP, AI-agent integrations, APIs, authentication, and webhooks, with reproducible developer-facing diagnostics and machine-readable agent discovery.
Start with the [Diagnostic Hub](NAIF-GRAVITY.md) or visit NAIF Gravity.
New — GitHub Issue Radar (14 Oct 2026): Read source-linked MCP and x402 failure diagnoses, proposed fixes, and regression checks. Public technical notes only; no third-party patches or paid transactions were performed.
This repository contains public diagnostic guidance, a small Python MCP health-check script, issue templates, and discovery metadata. It is not a complete source distribution of the hosted service.
What’s new: Micro Tools V2 — free preview, paid report
Broken JSON? Unexpected API response? Need consistent data output? Preview your sanitized sample at no charge, then choose a one-time report if the bounded result is useful. No subscription and no payment during preview.
| Live Micro Tool V2 | One-time USD | What you receive after verified payment |
|---|---|---|
| JSON Validity Check | $1 | Pinpoint syntax issues; flag duplicate keys; safe trailing-comma repair where supported; inferred sample schema, CI snippet and SHA-256 receipt |
| API Response Shape Check | $2 | Compare two JSON response samples for added/removed keys and type changes; generate *sample-based* TypeScript/OpenAPI response schemas and QA notes (no live API probing) |
| JSON Normalize Mini | $3 | Stable key order, optional trimming/indentation, a change log, before/after sizes and SHA-256 receipt |
[Try a free preview of the three tools →](https://naifgravity.com/micro-v2?utm_source=github&utm_medium=repo_readme&utm_campaign=micro_tools_v2) · Browse the live catalog
Simple agent-to-report flow: request a sample preview (POST /api/micro-v2/preview), request and accept a fixed-price quote (POST /api/agent/quote → POST /api/quote/accept), select an eligible checkout rail returned by the response, then retrieve the bounded report (POST /api/micro-v2/deliver) using the private delivery token after payment verification. Base USDC and TRON USDT may be available to eligible international buyers; Saudi-classified buyers use Apple Pay with human authorization. Agent-wallet checkout instructions are not an instruction to transfer funds automatically.
All three tools accept sanitized, bounded samples (maximum 4,096 UTF-8 bytes). Paid V2 inputs and reports are encrypted at rest; the original input is cleared from active records after report generation, with report retrieval limited to seven days. Never submit secrets, raw customer records, private keys or payment credentials. Per-call x402 paid API tools are a separate purchase path; the fourth CSV tool remains $5.
Install NAIF JSON Rescue for your agent
NAIF JSON Rescue checks a sanitized JSON sample locally before any external call. The free Node.js checker does not upload data, modify files or spend funds. Optional hosted diagnostics provide the existing bounded JSON artifact through x402 on Base, only within the buyer's disclosure permission and payment budget. A valid syntax-only sample needs no paid call.
With the Skills CLI, review and install just this skill:
npx skills add naief9961-tech/ai-growth-engine --skill naif-json-rescueChoose your supported agent in the installer. Installing does not authorize payments or fund a wallet. For a free offline demonstration after cloning this repository:
node skills/naif-json-rescue/scripts/check-json.mjs skills/naif-json-rescue/assets/valid.jsonnode --test tests/naif-json-rescue.test.mjs
Requires Node.js 18+. The local checker validates syntax only; duplicate keys and JSON Schema conformance are outside its scope. The hosted check accepts at most 4096 UTF-8 bytes and supports only bounded trailing-comma repair. See the skill for live discovery, regional policy, spending limits and accurate delivery interpretation.
Live discovery for AI agents
NAIF Gravity is openly discoverable through its machine-readable, read-only entry points:
- A2A Agent Card — identity, skills, protocol interfaces.
- Remote MCP endpoint — Streamable HTTP; MCP clients should negotiate using the MCP protocol (a normal browser GET may return 405).
- AI service catalog and agent catalog API — use live descriptions, eligibility and purchase instructions.
- LLM capability guide and A2A discovery guide.
- A2A Registry listing and Official MCP Registry listing.
This repository's MCP metadata is broadcast to the official MCP Registry via a pinned, verified GitHub Actions publisher when it changes. Listing, crawling, or a registry publish does not prove a visit, a qualified lead, or a sale.
Launch offer — one-time technical services (October 12–26, 2026)
Expired promotion — historical prices below. This offer ended no later than 26 October 2026 at 05:40 UTC. Use the live service catalog and accepted quote for current prices.
Historical offer terms: The launch prices below applied to newly created eligible quotes through 2026-10-26 05:40 UTC (08:40 Saudi time) or the first 10 verified purchases of campaign products, whichever happens first. Existing quotes and past payments retain their original terms. These are prices for bounded technical-service jobs, not per-call x402 tools.
| Bounded technical service | Regular USD | Launch USD |
|---|---|---|
| NAIF API Fixer | $89 | $79 |
| Web3 QA Sprint | $99 | $89 |
| NAIF Data Factory | $129 | $115 |
| Repair CI Gate Pilot | $129 | $115 |
| RPC Reliability Audit | $129 | $115 |
| Web3 Backend Rescue | $149 | $129 |
| x402 Endpoint Sprint | $149 | $129 |
| Smart-Contract Integration Review | $179 | $159 |
| Agentic Wallet & Payments | $199 | $179 |
| Automation Factory | $199 | $179 |
| AI Agent Engineering Sprint | $249 | $219 |
| Wallet Authentication Integration | $249 | $219 |
| Trading Agent Infrastructure Sprint | $299 | $269 |
| Web3 Automation Pilot | $399 | $349 |
For real-time eligibility and exact currently purchasable prices, agents should call the live agent catalog, then POST /api/agent/quote → POST /api/quote/accept → select an eligible payment rail. Use the amount returned in the accepted quote and checkout; never calculate a discount client-side. USDC on Base and USDT on TRON may be available to eligible international requests; Apple Pay requires a human handoff. Wallet availability follows country and purchase policy. Quote acceptance alone never transfers funds or triggers implementation. Most engineering products require a verified paid Work handoff and are not instant downloadable results.
Instant x402 API tools (separate from launch offer)
These four published full-scope paid API endpoints remain at their existing exact per-call prices until the payment challenge and live catalog are changed together:
| API tool | Price per call | Endpoint (POST) |
|---|---|---|
| JSON Validity Check | $1.00 USDC | x402 JSON validity |
| API Response Shape Check | $2.00 USDC | x402 response shape |
| JSON Normalize Mini | $3.00 USDC | x402 JSON normalize |
| CSV Schema Audit Mini | $5.00 USDC | x402 CSV schema |
Discover supported routes using the x402 manifest, x402 catalog, and OpenAPI. All four are published as self-registered services in 402 Index and are discoverable via Agent402, which currently recognizes four tools on Base. Lite trial rates have not been published: do not request, quote, or announce them as live. A successful 402 challenge or an external directory listing is not proof of a settled sale or inclusion in Coinbase Bazaar.
Individual purchases (no new recurring billing)
The services catalog lists the current individual, one-time technical services. New monthly subscriptions are paused. Pricing, purchase eligibility and region-specific payment options must be obtained from the live store; do not rely on older subscription offers, cached prices or an assumed wallet/payment path. Existing customer subscriptions and past payments are unaffected by this discovery documentation.
Coinbase-compatible x402 tools — self-hosted merchant profile
Publisher: NAIF Gravity · Network: Base Mainnet (eip155:8453) · Asset: USDC · API: x402 v2 · Billing: one-time per call, no subscription. NAIF Gravity's public branded x402 merchant metadata has an official project logo, exact payment requirements, structured input/output schemas, and a link to the live product catalog. A request without payment receives the Payment-Required response and does not deliver the paid artifact.
| When an agent needs | Public POST resource | Exact x402 price |
|---|---|---|
| Diagnose malformed JSON or a supported trailing-comma syntax error | JSON Validity Check | $1 USDC |
| Inspect JSON REST/MCP API response fields, types and expected keys | API Response Shape Check | $2 USDC |
| Canonicalize a small JSON object/array and receive a SHA-256 checksum | JSON Normalize Mini | $3 USDC |
