## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-08.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 791 tokens (~131/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 92/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 75% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-08 (score 69, +2)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 23. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-04 (score 67, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

First indexed and scored.

## MCP tools (6)

### `list_chains` (~28 tokens)

List supported chains

Chains available right now, which ids can be a source or a destination, and featured tokens.

### `search_tokens` (~90 tokens)

Search tokens

Find a token address and decimals by symbol, name or address.

Input parameters:

- `chainId` (integer): Chain id from list_chains.
- `direction` (string, required): "from" = you send it, "to" = you receive it.
- `limit` (integer)
- `offset` (integer)
- `query` (string): Symbol, name or address, e.g. "USDC".

### `get_quote` (~161 tokens)

Quote a swap

Estimate a swap. side "from" (default) quotes spending `amount`; side "to" quotes receiving `amount`. A quote is an estimate, not a funding instruction.

Input parameters:

- `amount` (string, required): Human decimal amount, e.g. "0.5". Not atomic units.
- `fromChainId` (integer, required): Chain id from list_chains.
- `fromToken` (string, required): Token address from search_tokens, or "native" for the chain coin.
- `side` (string)
- `toAddress` (string): Recipient address; improves the estimate.
- `toChainId` (integer, required): Chain id from list_chains.
- `toToken` (string, required): Token address from search_tokens, or "native" for the chain coin.

### `create_swap` (~190 tokens)

Create a swap order

Create a durable order that spends `amount` of fromToken. Returns the deposit address and exact amount to send. Confirm with the user first. Never retry after a timeout or error: another call creates another order.

Input parameters:

- `amount` (string, required): Human decimal amount, e.g. "0.5". Not atomic units.
- `fromChainId` (integer, required): Chain id from list_chains.
- `fromToken` (string, required): Token address from search_tokens, or "native" for the chain coin.
- `refundAddress` (string): Only for a native-coin source such as XMR or TRX; token sources refund to the sender.
- `toAddress` (string, required): Recipient address on toChainId.
- `toChainId` (integer, required): Chain id from list_chains.
- `toToken` (string, required): Token address from search_tokens, or "native" for the chain coin.

### `get_swap` (~50 tokens)

Read a swap order

Current status and customerState of an order. Amounts are atomic; *Decimals fields give scale.

Input parameters:

- `orderId` (string, required)
- `sessionId` (string, required): The sessionId create_swap returned.

### `set_refund_address` (~75 tokens)

Save a refund address

Only when get_swap shows customerState { kind: "action_required", action: "refund_address" }. Saves one immutable destination; it does not start a transfer by itself.

Input parameters:

- `orderId` (string, required)
- `refundAddress` (string, required)
- `sessionId` (string, required): The sessionId create_swap returned.

### Is the Wagyu MCP server safe to use?

Wagyu scores 69 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Wagyu MCP server expose?

Wagyu exposes 6 tools: list_chains, search_tokens, get_quote, create_swap, get_swap, set_refund_address. Their descriptions and schemas cost roughly 594 tokens of context every time the server is loaded.

### Does the Wagyu MCP server require authentication?

No. We connected to Wagyu without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Wagyu MCP server still maintained?

Wagyu is still listed as active in the MCP registry. We last reached this channel on 8 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
