Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability71
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage92
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 75% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Wagyu MCP server?
Wagyu is a hosted endpoint at https://mcp.wagyu.xyz/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_swap Create a swap order ~190
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.
| Name | Type | Req | Description |

| amount | string | yes | Human decimal amount, e.g. "0.5". Not atomic units. |
| fromChainId | integer | yes | Chain id from list_chains. |
| fromToken | string | yes | 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 | yes | Recipient address on toChainId. |
| toChainId | integer | yes | Chain id from list_chains. |
| toToken | string | yes | Token address from search_tokens, or "native" for the chain coin. |
No output schema declared.
No examples provided.
get_quote Quote a swap ~161
Estimate a swap. side "from" (default) quotes spending `amount`; side "to" quotes receiving `amount`. A quote is an estimate, not a funding instruction.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | string | yes | Human decimal amount, e.g. "0.5". Not atomic units. |
| fromChainId | integer | yes | Chain id from list_chains. |
| fromToken | string | yes | Token address from search_tokens, or "native" for the chain coin. |

| toToken | string | yes | Token address from search_tokens, or "native" for the chain coin. |
No output schema declared.
No examples provided.
get_swap Read a swap order ~50
Current status and customerState of an order. Amounts are atomic; *Decimals fields give scale.
| Name | Type | Req | Description |
|---|---|---|---|
| orderId | string | yes | – |
| sessionId | string | yes | The sessionId create_swap returned. |
No output schema declared.
No examples provided.

What is the Wagyu MCP server?
Wagyu is an MCP server listed in the public MCP registry as xyz.wagyu/wagyu. Swap crypto across chains, including Monero (XMR): quote, create and track swaps. This page covers its hosted endpoint (https://mcp.wagyu.xyz).
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.
