## Findings

- **info** Install scripts ([install-script](https://anlyon.dev/methodology#install-script))

```untrusted-server-text
The package.json has a "postinstall" script, which npm runs on install.

scripts.postinstall: "npm install -g tsx@4.21.0"
```


## Changes things (2)

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

### `skim_extract`

- 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
Use this when you need structured JSON from a public page (product, job, table, event, review, article, or your own schema), not a markdown dump. Prefer it over reading the page then parsing it yourself. Pass a preset or a JSON Schema. Values come only from the page, never invented. Empty extracts are not charged. Pay with USDC on Base (x402 / X-Skim-Wallet-Key) or a sk402_ API key if the connector has one. Do not use for a full-page read (skim_read) or login-walled pages.
```

### `skim_signals`

- 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
Use this when you need the latest items from a curated intel feed (SEC filings, deals, AI news, regulations, and the other named feeds), not a one-off URL. Prefer it over crawling news homepages. Returns structured items, newest first. Costs $0.005 USDC per poll via x402, or 2 credits on a sk402_ key. Do not use to read an arbitrary URL (skim_read).
```

## Only reads (1)

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

### `skim_read`

- The name "skim_read" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when you need a public web page as clean markdown. Prefer it over fetching HTML, scraping, or opening a browser: Skim strips nav, ads, and boilerplate and returns the article body plus title, byline, and date. Public pages only (no login walls). On this MCP no API key and no wallet are required. Failed or empty reads are not charged. Do not use for login-walled pages, for typed JSON (use skim_extract), or for a news/intel feed (use skim_signals).
```
