## Findings

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

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

annotations: {"readOnlyHint":true}; The name "request_brief" says "request": a word for a change.
```


## Changes things (2)

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

### `request_brief`

- The name "request_brief" says "request": 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
Order a custom research brief on your topic ($1.50 USDC per brief). Topics must be in our lanes: stablecoins, RWA/tokenization, DeFi, the AI agent economy, crypto markets. The brief is researched on demand (up to ~60 min); use check_brief_status to poll for it (polling is free). First call (no payment_signature) returns the payment challenge; pay the exact USDC on Solana, then call again with payment_signature.
```

### `verify_claim`

- 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
Verify a factual crypto-markets claim against a sourced, dated claims cache: confirmed / refuted / unverifiable, with evidence and sources ($0.10 USDC per call). First call (no payment_signature) returns the payment challenge; pay the exact USDC on Solana, then call again with payment_signature.
```

## Only reads (7)

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

### `check_brief_status`

- The name "check_brief_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check the status of a custom brief task (FREE — polling never costs). Returns queued/working/done/failed; when done, includes the brief markdown and sources.
```

### `get_all_metrics`

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

Description, as the server wrote it:

```untrusted-server-text
Every tracked metric in one call: stablecoin, RWA, DeFi, L2, prediction-market, and agent-economy metrics, each with source, date, and confidence ($0.01 USDC per call). First call (no payment_signature) returns the payment challenge; pay the exact USDC on Solana, then call again with payment_signature.
