## Changes things (4)

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

### `brand_feedback`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Ask real humans a short brand or product question via WURK. Returns replies plus sentiment. Can take minutes. Costs 0.50 USDC, settled by POST https://api.bilbop.org/brand-feedback. payTo 2r2vsoyuYuy4dsyQVRhfmMBqsMRKHRS5FTPNumYFhxE4. Pay the resource URL in the 402 challenge, then retry with PAYMENT-SIGNATURE or X-PAYMENT forwarded by this MCP.
```

### `sol_mint_info`

- 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.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
On-chain facts for a Solana SPL mint: supply, decimals, mint authority, freeze authority. Costs 0.01 USDC, settled by POST https://api.bilbop.org/v1/sol-mint-info. payTo 2r2vsoyuYuy4dsyQVRhfmMBqsMRKHRS5FTPNumYFhxE4. Pay the resource URL in the 402 challenge, then retry with PAYMENT-SIGNATURE or X-PAYMENT forwarded by this MCP.
```

### `sol_token_brief`

- Nothing in its name or description says what it does, so it is counted as a write.

- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Solana SPL token market snapshot (price, market cap, liquidity, 24h volume) plus a one-line brief.

### `tts`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

## Only reads (1)

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

### `summarize`

- The name "summarize" says "summarize": a word for reading.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Summarize text into 1-3 concise sentences. Costs 0.01 USDC on Solana, settled by POST https://api.bilbop.org/v1/summarize (not by this MCP host). payTo 2r2vsoyuYuy4dsyQVRhfmMBqsMRKHRS5FTPNumYFhxE4. Call the tool; on HTTP 402, pay the resource URL in the challenge, then retry this tool with the same arguments and the PAYMENT-SIGNATURE or X-PAYMENT header on the MCP request. This server forwards that header and does not custody funds.
```
