## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `geo_audit`

- 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
Audits how visible one web page is to AI search engines and AI assistants: which of the major AI crawlers robots.txt allows or blocks, llms.txt and llms-full.txt presence, sitemap, and on-page signals (title, meta, canonical, structured data, headings, content readable without JavaScript). Returns a 0-100 score, grade and prioritised recommendations. Use it to check or monitor a site for generative-engine optimisation. Price: $0.02 per call, paid with x402.
```

### `llms_txt_check`

- 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
Checks whether a domain publishes /llms.txt and /llms-full.txt and validates llms.txt against the llmstxt.org structure: single H1 title, blockquote summary, H2 sections with markdown link lists, soft-404 detection and size. Respects robots.txt. Use it before or after publishing an llms.txt file. Price: $0.005 per call, paid with x402.
```

## Only reads (3)

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

### `ai_crawler_matrix`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads a domain's robots.txt (RFC 9309 matching) and reports, for each known AI crawler and AI agent (OpenAI, Anthropic, Google, Perplexity, Apple, Meta, Amazon, Common Crawl and others), whether it may fetch the site root and up to five extra paths, with the deciding rule and any Content-Signal preferences. Use it to see whether a site is open to AI search but closed to AI training. Price: $0.01 per call, paid with x402.
```

### `india_id_validate`

- The name "india_id_validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validates and decodes one Indian business or payment identifier offline: GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers. Detects the type automatically, normalises copy-paste noise, verifies check digits where the algorithm is public (GSTIN), and decodes embedded fields such as state, PAN holder type or company type. Aadhaar numbers are refused. Use it to clean or pre-check form and invoice data. Price: $0.005 per call, paid with x402.
```

### `india_id_validate_batch`

- The name "india_id_validate_batch" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Batch version of the Indian identifier validator: up to 50 values per call (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers), mixed types allowed, one flat price. Returns one decoded result per item plus counts by type and validity. Use it for cleaning vendor lists, invoices or onboarding data. Batches containing Aadhaar-like numbers are rejected without charge. Price: $0.02 per call, paid with x402.
```
