## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `purchase`

- The name "purchase" says "purchase": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Wraps `GET /api/r/:owner/:slug` — the same quote → screen → verify → settle → grant sequence, with the purchase recorded as `source: mcp`. Call it once with no payment: you get the x402 `PaymentRequired` body back. It arrives as `isError: true` per the x402 MCP transport, but it is not a failure — it is the price, and `accepts[0]` is the requirement to sign. Sign that EIP-3009 authorization with your own key (this server never sees it) and call again with the payment as the base64 `payment_signature` argument or as `_meta["x402/payment"]`. On success you get the version, the sha256 of the artifact, a signed download URL that expires in five minutes, and the settlement transaction in `_meta["x402/payment-response"]`. Access is granted only after the facilitator returns a transaction hash. A $0 listing returns `granted` on the first call.
```

## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_version`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Wraps `GET /api/v/:owner/:slug`. The cheap call to make before every run: the latest version, when it was published, and the price. With `wallet_signature` it also answers what that wallet already owns and what the *next* fetch would cost it — `price_kind` is `new`, `update`, `free` or `owned`. Without one it never reveals what any address owns.
```

### `how_to_buy`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Free, no wallet needed. Returns whether the listing is for sale, its latest version and new-buyer price, the listing page a person can buy on with a browser wallet, the step-by-step skill an agent with a wallet follows, the raw x402 endpoint, and this server's URL. If you cannot sign transactions, answer the person with `without_a_wallet`; if you can, follow `with_a_wallet` or call `purchase`.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `fetch_release`

- The name "fetch_release" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Wraps `GET /api/r/:owner/:slug/v/:version`. A fresh five-minute download URL for a version this wallet already bought. Free, forever, including after the listing is retired. Never sells anything: if the wallet does not hold that version it is `not_entitled`, not a 402. `wallet_signature` is required — without a proved wallet there is nobody to be entitled.
```

### `get_listing`

- The name "get_listing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Wraps `GET /api/label/:owner/:slug`. The free, unauthenticated manifest for a listing's latest passing release: file tree, sizes, licence, dependencies, security-scan result and release log. Costs nothing and needs no wallet, so read it before you buy. Computed facts and the creator's own claims are separately namespaced (`computed` vs `self_reported`).
```

### `search_listings`

- The name "search_listings" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free, no wallet needed. Searches every live listing — private repos, agent skills, prompt packs, toolkits — by what it does: the name, the creator's description and "use this when" line, the computed tags (artifact class, what is inside such as `skills` or `scripts`, languages) and the README. Describe the job in plain words, e.g. `humanize ai writing` or `changelog from git history`; leave `query` empty to list everything. Results are ordered by how many of your words matched and where, then by name — never by sales or popularity. Each result has the `owner` and `slug` the other tools take: read `get_listing` for the file tree and security scan, then `how_to_buy`.
```
