## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-24.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1506 tokens (~150/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (10)

### `capabilities` (~66 tokens)

Describe Vortex

Return the full machine-readable manifest of Vortex: every operation, its price in USD, its input schema and how to pay. Free.

When to use: Call this first if you have never used Vortex and want to know what it can do and what it costs.

Price: Free.

### `identity_create` (~142 tokens)

Claim an identity

Turn a wallet address into a permanent Vortex identity and an API token. Free, and grants a small trial credit. No signup, no email, no human.

When to use: Call this once, before anything else. You need the returned token for every other call.

Price: Free.

Input parameters:

- `label` (string): A name for your own reference.
- `message` (string, required): Must contain your wallet address and a timestamp within the last 10 minutes.
- `signature` (string, required): EIP-191 personal_sign of the message field, proving you control the wallet.
- `wallet` (string, required): Your EVM wallet address. This is your permanent identity.

### `whoami` (~45 tokens)

Who am I

Your handle, wallet, balance and usage. Free.

When to use: Call this to check your balance before a run, or to confirm your token still works.

Price: Free.

### `credit_deposit` (~89 tokens)

Top up balance

Buy Vortex credit with USDC on Base over x402. One on-chain settlement, then every call is debited off-chain.

When to use: Call when your balance is low. Operations cost fractions of a cent, so a single deposit covers hundreds of them.

Price: Free.

Input parameters:

- `amount_usd`: One of 1, 5 or 20. Defaults to 1.

### `find` (~206 tokens)

Find something that can actually reach you

Search real storefronts for a product and get back only the ones that can ship to your destination, with live price and stock. Every other product index answers what matches the words; this one answers what matches the words and can be delivered.

When to use: Call this before shopping anywhere else. Most storefronts serve one country: a search that ignores reach will hand you results your buyer can never receive, and you find out at checkout after the work is done.

Price: US$0.005000 per call.

Input parameters:

- `destination` (string, required): ISO 3166-1 alpha-2 country the goods must reach. Example: BR, US, DE.
- `in_stock_only` (boolean): Only return products with a variant in stock.
- `limit` (integer): How many stores to return.
- `max_price_usd`: Skip anything above this shelf price.
- `need` (string, required): What you are looking for, in plain language. Example: merino wool sneakers.

### `feasibility` (~158 tokens)

Can this store deliver here

Everything Vortex knows about whether one storefront can serve one destination: its published shipping zones, the currency it charges in, the cards it takes, what buyers reported, and whether its reach changed recently. Returns a verdict, not just data.

When to use: Call this when you already have a store in mind and are about to spend real money. Answers reaches, cannot_reach or unknown, and says which of the three it is rather than guessing.

Price: US$0.002000 per call.

Input parameters:

- `destination` (string, required): ISO 3166-1 alpha-2 country the goods must reach. Example: BR, US, DE.
- `store` (string, required): Store domain or any URL on it. Example: allbirds.com

### `landed` (~206 tokens)

What it really costs there

Item plus shipping plus import tax plus local tax, itemised, for a destination — and the name and effective date of the tax rule applied. A US$120 item into Brazil lands near US$220; the shelf price is not the number to budget against.

When to use: Call this before committing to a cross-border purchase, and before comparing two stores in different countries. If Vortex has no rule on file for the destination it says so instead of returning a confident guess.

Price: US$0.003000 per call.

Input parameters:

- `destination` (string, required): ISO 3166-1 alpha-2 country the goods must reach. Example: BR, US, DE.
- `item_usd`: Shelf price, if you are not passing a product URL.
- `product` (string): A product URL. Its price is looked up for you.
- `shipping_usd`: Freight, if you already have a quote. Omitted means the total excludes it and says so.

### `history` (~130 tokens)

Is this price good

The recorded price and stock series for a product, where today sits against its own record, how often it has gone out of stock, and every change to where its store ships.

When to use: Call this when you have a candidate and want to know whether to buy now or wait. Vortex says how many observations it actually has and withholds the percentile when the series is too short to mean anything.

Price: US$0.002000 per call.

Input parameters:

- `days` (integer): How far back to look.
- `product` (string, required): A product URL exactly as Vortex returned it from find.

### `watch` (~165 tokens)

Tell me when it changes

Register standing interest in a product or a store: a price drop below your threshold, a return to stock, or a store that stops shipping to your destination.

When to use: Call this instead of polling find on a schedule. One watch costs less than two searches and catches the change at the moment it happens.

Price: US$0.005000 per call.

Input parameters:

- `below_usd`: For price_drop: notify under this price.
- `callback_url` (string): Optional. Vortex POSTs here on a change.
- `destination` (string): Required for reach_change.
- `kind` (string, required): What you want to be told about.
- `product` (string): Required for price_drop and back_in_stock.
- `store` (string): Required for reach_change.

### `report` (~174 tokens)

Report what happened

Tell Vortex how a purchase actually went. Free, and checked against the merchant's own feed before it counts — a claim the store contradicts is stored and marked contradicted rather than believed.

When to use: Call this after any purchase attempt, good or bad. It is free, it makes every later answer better, and reporting the freight you were quoted is the one number Vortex cannot collect for itself.

Price: Free.

Input parameters:

- `destination` (string): Where you were shipping to.
- `detail` (string): What happened, in your own words.
- `outcome` (string, required): What actually happened when you tried to buy.
- `product` (string, required): A product URL exactly as Vortex returned it from find.
- `shipping_usd`: What freight was quoted. This is what makes landed costs accurate for everyone.

## Common questions

### What is the Vortex MCP server?

Vortex is an MCP server listed in the public MCP registry as dev.rohnelt.vortex/vortex. Which stores can actually ship to your destination, at what real landed cost. This page covers its hosted endpoint (https://vortex.rohnelt.dev/mcp).

### Is the Vortex MCP server safe to use?

Vortex scores 79 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Vortex MCP server expose?

Vortex exposes 10 tools: capabilities, identity_create, whoami, credit_deposit, find, and 5 more. Their descriptions and schemas cost roughly 1,381 tokens of context every time the server is loaded.

### Does the Vortex MCP server require authentication?

No. We connected to Vortex without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Vortex MCP server still maintained?

Vortex is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
