## 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__liquidity__trdefi_badge` `mcp__liquidity__trdefi_chains` `mcp__liquidity__trdefi_position_detail` `mcp__liquidity__trdefi_positions` `mcp__liquidity__trdefi_quote` `mcp__liquidity__trdefi_stats` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Changes things (6)

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

### `trdefi_badge`

- 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
A shields.io endpoint payload for the catalogue metrics, so a README can show live figures. Metrics: volume30, volume7, volume1, strategies, makers, pairs, chains.
```

### `trdefi_chains`

- 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
The networks where liquidity is live right now, with each network's settlement engine address and the tokens a position can be built from. Use this instead of hardcoding chain or token identifiers.
```

### `trdefi_position_detail`

- 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
One position in full, by its 32-byte strategy hash.
```

### `trdefi_positions`

- 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
Live non-custodial liquidity, as positions an agent can actually trade against. Each row carries the strategy hash, network, pair, tokens, settled volume and a `quote_eligible` flag, meaning the position is router-attached and its network has a quote route. It does NOT mean the position will quote: a maker can still gate it. Use this before a swap to find a real on-chain counterparty, or to survey where liquidity sits. Filter by network and by pair. Free, no key, no custody.
```

### `trdefi_quote`

- 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.
- Findings: info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Price a swap against one position, on-chain, at the current block — no custody, nothing signed, nothing moved. Works on any pair the position trades, not only stablecoins. Use this to check liquidity and get the output amount before preparing a swap. If a position answers "Strategy is gated", the maker embedded an access-licence check in the order: the CALLER must hold the 1inch Aqua access token. That check reads tx.origin, so the revert depends on whether a caller was supplied: without one it is 0x89c62b64 ("the caller holds none"), with one it is 0x39c4052c (the tx-origin balance check). Pass `from` with the address that will actually sign the swap. A caller that holds the maker's credential gets a real price; anyone else gets an accurate "you do not hold it" instead of the least specific answer available. This is a property of the strategy, not a bug — and it is strongly per-network. Measured 2026-10-19: on Ethereum 58 of 60 sampled positions are gated, and across 17 networks the network-balanced split is about 62 percent gated and 17 percent priced. The credential contract itself is only deployed on the 13 Aqua chains, so Arc, Monad, Cronos and HyperEVM have no such gate. Quotes are simulated on 17 networks: ethereum, base, arbitrum, optimism, polygon, arc, bnb-chain, gnosis, avalanche, sonic, linea, zksync-era, monad, unichain, hyperevm, cronos and robinhood-chain. This list is the set the quote path actually serves; if a network is not on it, do not promise a quote for it.
```

### `trdefi_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
Aggregate statistics for the live TRDEFI non-custodial stablecoin liquidity catalogue: how many open maker positions exist, how many distinct makers, how many pairs, across how many networks, plus settled volume over 1, 7 and 30 days, and the deepest pairs by volume and by position count. Free, no key.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `liquidity`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__liquidity__trdefi_stats",
      "mcp__liquidity__trdefi_chains",
      "mcp__liquidity__trdefi_positions",
      "mcp__liquidity__trdefi_position_detail",
      "mcp__liquidity__trdefi_quote",
      "mcp__liquidity__trdefi_badge"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__liquidity__trdefi_stats`: untrusted-input
- `mcp__liquidity__trdefi_chains`: untrusted-input
- `mcp__liquidity__trdefi_positions`: untrusted-input
- `mcp__liquidity__trdefi_position_detail`: untrusted-input

| HTTP status of an anonymous initialize | `200` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://yield.trdefi.com/mcp: tools/list returned 6 tools to an anonymous client, including trdefi_stats (write), trdefi_chains (write), trdefi_positions (write), trdefi_position_detail (write), trdefi_quote (write) and 1 more
