## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__dexra__clmm_range_stats` `mcp__dexra__describe_address` `mcp__dexra__market_snapshot` `mcp__dexra__new_launches` `mcp__dexra__new_launches_batch` `mcp__dexra__pool_health` `mcp__dexra__score_performance` `mcp__dexra__service_stats` `mcp__dexra__swap_preflight` `mcp__dexra__token_deep_check` `mcp__dexra__token_holders_delta` `mcp__dexra__wallet_check` |

## Changes things (10)

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

### `clmm_range_stats`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
For Raydium CLMM, Orca Whirlpool and Meteora DLMM: liquidity by price, share of time a range of the given width would have stayed in range over 7 and 30 days, fee yield inside the range, impermanent loss and how many rebalances it would have needed. Returns a verdict (ok, caution, avoid, or unknown when data is missing) with reasons. Price: 0.020 USDC per call, included in subscriptions.
```

### `new_launches`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
New tokens and pools on Solana (pump.fun, LetsBonk, Raydium LaunchLab, Meteora DBC, PumpSwap, Raydium AMM and CPMM) from the last N minutes with mint and freeze authority, liquidity and lock, creator history and links to past collapses, and the first-buyer funding graph: same-block buyers, wallets funded by the creator or by one shared address, known snipers. Each launch has a verdict (ok, caution, avoid, or unknown when data is missing) with reasons. Up to 20 launches per answer, or as many as the plan's batch size. Windows over 60 minutes or more than 20 launches cost more. Price: 0.005 USDC per call, included in subscriptions.
```

### `new_launches_batch`

Description, as the server wrote it:

```untrusted-server-text
The same checks as new_launches (authorities, liquidity and lock, creator history, first-buyer funding graph), plus Token-2022 extensions that can trap holders, for Solana token mints you already know about, in one call: up to 5 on Free, 50 when paid per call, or the plan's batch size (max_batch in /billing/plans). Each launch has a verdict (ok, caution, avoid, or unknown when data is missing) with reasons. Price: 0.015 USDC per call, included in subscriptions.
```

### `pool_health`

- 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
For Raydium AMM, CPMM and CLMM, Orca Whirlpool, Meteora DLMM and PumpSwap pools: depth within 2%, slippage for $1k and $10k, 24h liquidity inflow or outflow, LP return versus holding over 7 and 30 days after impermanent loss, bot and sandwich share of volume.

Description, as the server wrote it:

Free. For every launch risk flag we publish: how often flagged tokens collapsed within 24h versus the base rate across all launches, sample size, test window and daily drift. Price: free.
```

### `service_stats`

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

- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Before a Solana swap: price impact on the best route, sandwich share on the pool from our history, Token-2022 transfer fees, hooks and permanent delegate, mint and freeze authority. Returns a verdict (ok, caution, avoid) with reasons, and the assessment behind it (ok, unverified, high_slippage_risk, high_sandwich_risk, blocked). Price: 0.005 USDC per call, included in subscriptions.
```

Description, as the server wrote it:

```untrusted-server-text
Use before buying or holding a Solana token to see who really holds it: which top holders were funded from the same address, real concentration after merging linked wallets, holder and liquidity dynamics from our snapshot history, blacklist proximity within two transfers, and the mint's authorities and Token-2022 extensions (transfer fee, hook, permanent delegate). Returns a verdict (ok, caution, avoid, or unknown when data is missing) with reasons. Goes deeper than a single safety score such as RugCheck's. Price: 0.030 USDC per call, included in subscriptions.

Returns a verdict (ok, caution, avoid, or unknown when data is missing) with reasons. Price: 0.030 USDC per call, included in subscriptions.
```

Free. Call first with any Solana address to learn what it is: wallet, program, pool or token, its age, activity and basic stats. Points to the paid tool that answers the next question (wallet_check, pool_health, token_deep_check). Price: free.

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 10 tools that change things (10 write). Whether a call also works without credentials was not tested: tools are never called.
