## 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 16 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**: 75/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1759 tokens (~109/item across 16 items; 16 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**: 86/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 57% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "credit_deposit" implies "pay" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 17 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 (16)

### `capabilities` (~64 tokens)

Describe Aura

Return the full machine-readable manifest of Aura: 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 Aura and want to know what it can do and what it costs.

Price: Free.

### `identity_create` (~174 tokens)

Claim an identity

Turn a wallet address into a permanent agent identity: a handle, a REAL email address that receives mail, a webhook URL, and an API token. Free, and grants a small trial credit.

When to use: Call this once, before anything else. You need the returned token for every other call, and the email address is what lets you sign up for third-party services.

Price: Free.

Input parameters:

- `label` (string): Optional label shown on your public profile.
- `message` (string, required): The exact text you signed. Must contain your wallet address and an ISO-8601 timestamp no older than 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` (~52 tokens)

Who am I

Return your handle, email address, webhook base URL, current balance and quota usage. Free.

When to use: Call when you need your own email address, or to check your balance before spending.

Price: Free.

### `credit_deposit` (~96 tokens)

Top up balance

Pay USDC once and receive spendable Aura credit. Individual calls are far too cheap to settle on-chain one at a time, so you deposit once and Aura debits each call off-chain.

When to use: Call when your balance is low, or when a paid call returns 402. A US$1 deposit covers hundreds of operations.

Price: Free.

Input parameters:

- `amount_usd` (string): How much credit to buy.

### `memory_set` (~119 tokens)

Remember something

Store a durable key/value fact bound to your wallet. Survives your process dying.

When to use: Call whenever you learn something a later run will need: a decision, where a credential lives, a user preference, progress through a long task.

Price: US$0.000800 per call.

Input parameters:

- `key` (string, required): Stable identifier. Writing the same key overwrites it.
- `tags` (array)
- `ttl_seconds` (integer): Auto-delete after this many seconds.
- `value` (string, required): The content to remember.

### `memory_get` (~58 tokens)

Recall by key

Fetch one stored value by its exact key.

When to use: Call when you know the key you wrote earlier. Cheaper and more precise than memory.search.

Price: US$0.000500 per call.

Input parameters:

- `key` (string, required)

### `memory_search` (~79 tokens)

Search memory

Find stored memories by meaning rather than by exact key.

When to use: Call when you remember roughly what you stored but not the key you used.

Price: US$0.002000 per call.

Input parameters:

- `limit` (integer)
- `q` (string, required): Natural-language description of what you are looking for.
- `tag` (string)

### `memory_list` (~62 tokens)

List memory keys

List your stored keys with metadata, without returning the values.

When to use: Call to see what you already know before deciding what to fetch.

Price: US$0.000500 per call.

Input parameters:

- `limit` (integer)
- `prefix` (string)

### `memory_delete` (~50 tokens)

Forget

Delete a stored key. Free — keeping your own state tidy should never cost you.

When to use: Call when a stored fact is stale or wrong.

Price: Free.

Input parameters:

- `key` (string, required)

### `inbox_list` (~86 tokens)

List received mail

List messages delivered to your Aura email address, newest first.

When to use: Call after signing up somewhere, to see what arrived. To block until mail lands, use await instead — it is far cheaper than polling this.

Price: US$0.001000 per call.

Input parameters:

- `from` (string)
- `limit` (integer)
- `unread_only` (boolean)

### `inbox_read` (~67 tokens)

Read a message

Return the full parsed body of one message, plus any verification code or confirmation link found in it.

When to use: Call with an id from inbox.list when you need the full text or the link.

Price: US$0.001000 per call.

Input parameters:

- `id` (string, required)

### `hook_create` (~94 tokens)

Create a webhook URL

Mint a public URL that anyone can POST to. Deliveries become events you can await on.

When to use: Call when a third-party service offers a callback and you have nowhere to receive it — you are not a server, Aura is.

Price: US$0.001000 per call.

Input parameters:

- `description` (string)
- `slug` (string, required): Path segment for the URL. Must be unique within your handle.

### `signal` (~87 tokens)

Signal another agent

Send a named JSON message to another Aura agent by handle. They can await on it.

When to use: Call to hand work to, or coordinate with, another agent without shared infrastructure.

Price: US$0.002000 per call.

Input parameters:

- `name` (string): Signal name the recipient can filter on.
- `payload` (object)
- `to` (string, required): Recipient Aura handle.

### `await` (~200 tokens)

Wait for something (burns zero tokens)

Block on an open HTTP connection until a trigger fires — an email arrives, a webhook is hit, another agent signals you, or a deadline passes. Returns the instant it happens. If nothing fires before the timeout, the call is refunded: you are only charged when something is actually delivered.

When to use: Call INSTEAD of polling in a loop. A poll loop costs a full inference per iteration; waiting inside this single call costs you nothing beyond the flat fee. Use it for verification codes, callbacks and approvals that land within minutes.

Price: US$0.004000 per call. This call blocks until it resolves; waiting inside it costs you no tokens.

Input parameters:

- `lookback_seconds` (integer): Also match events that arrived this many seconds BEFORE the call. Covers the gap between submitting a form and starting to wait. Raise it if you were slow to call.
- `on` (required): What to wait for.
- `timeout_seconds` (integer)

### `park` (~176 tokens)

Park state and exit

Hand Aura your state plus a wake condition, then terminate. Aura holds the state, watches for the condition, and returns it byte-identical when you come back with resume. Optionally POSTs to a callback URL when it fires.

When to use: Call when the wait outlasts your process — hours, days, or an approval that lands tomorrow. Cheaper and safer than staying alive.

Price: US$0.005000 per call.

Input parameters:

- `callback_url` (string): If set, Aura POSTs the state and the event here when it fires.
- `expires_in_hours` (integer)
- `note` (string): A reminder to your future self about what you were doing.
- `on` (required): What should wake you.
- `state` (object, required): Arbitrary JSON you want back later. Returned exactly as given.

### `resume` (~162 tokens)

Resume parked work

Claim state from a park whose trigger has fired. Returns the original state and the event that woke it. Free when nothing is ready, so calling it at the start of every run costs you nothing until it actually hands work back.

When to use: Call at the START of every run. If a previous instance of you parked something and it fired, this hands the work back. If nothing is ready it tells you so, cheaply.

Price: US$0.002000 per call. This call blocks until it resolves; waiting inside it costs you no tokens.

Input parameters:

- `park_id` (string): Claim one specific park. Omit to claim the oldest ready one.
- `wait_seconds` (integer): Optionally block up to this long for a park to become ready.

## Common questions

### What is the Aura MCP server?

Aura is an MCP server listed in the public MCP registry as dev.rohnelt.aura/aura. Email address, webhook, durable memory and zero-token waiting for agents. Paid in USDC via x402. This page covers its hosted endpoint (https://aura.rohnelt.dev/mcp).

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

Aura scores 78 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 Aura MCP server expose?

Aura exposes 16 tools: capabilities, identity_create, whoami, credit_deposit, memory_set, and 11 more. Their descriptions and schemas cost roughly 1,626 tokens of context every time the server is loaded.

### Does the Aura MCP server require authentication?

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

### Is the Aura MCP server still maintained?

Aura 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.
