## Findings

- **warn** Annotations that disagree with the tool in `convert_document` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_document" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "convert_document" says "convert": a word for a change.
```


## Changes things (2)

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

### `convert_document`

- The name "convert_document" says "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a document up to 8 MB to Markdown and return it directly.

Pass the file as base64 in `content_base64`, or as a download link in
`file`, and its name in `filename`. The extension decides the type: .pdf,
.docx, .pptx, .xlsx, .html, .htm or .txt. Returns `markdown` and `meta`
(`filename`, `length` in characters). PDFs come back as plain text
without headings and without OCR. For scans, tables and page numbers,
use `submit_conversion_job`. Works without an API key at the anonymous
rate limit.

Credits: 1 per call.
```

### `submit_conversion_job`

- The name "submit_conversion_job" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Queue a document up to 25 MB and 200 pages for conversion with OCR and tables.

Pass the file as base64 in `content_base64`, or as a download link in
`file`, and its name in `filename` (.pdf, .docx, .pptx, .xlsx, .html,
.htm or .txt). Returns `job_id`, `status` and `result_url`. Call
`get_conversion_job` with the `job_id` until `status` is `succeeded` or
`failed`. A conversion may take up to about 2 minutes.

Optional `webhook_url`: a public http or https URL that receives a POST
with the job's final state. The request carries
`X-Appkit-Signature: sha256=<hex>`, an HMAC-SHA256 of the raw body keyed
with the returned `webhook_secret` (shown only once). 3 delivery attempts.

Requires an API key. The credits are refunded if the job fails. The
uploaded file is deleted when the job finishes. Results are kept for
7 days after submission.

Credits: 10 per call.
```

## Only reads (1)

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

### `get_conversion_job`

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

Description, as the server wrote it:

```untrusted-server-text
Check a queued conversion job you submitted.

Returns `job_id` and `status` (`queued`, `running`, `succeeded` or
`failed`). A succeeded job includes the `markdown` when it is under
100 KB, otherwise a `result_url` to download it (also free). A failed job
includes `error`, one sentence with the reason. Results are deleted
7 days after submission. An expired result is reported in `error`.
Requires an API key.

Credits: free. This tool is not metered.
```
