## 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 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 21 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3240 tokens (~154/item across 21 items; 21 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (21)

### `lz_broadcast_signed_tx` (~236 tokens)

Broadcast a pre-signed Ethereum transaction via eth_sendRawTransaction on the source chain RPC. Use this as the canonical broadcast path for calldata produced by lz_send_message (EndpointV2.send), lz_oft_send (OFT.send), lz_stargate_send (StargatePoolNative.sendToken), and lz_transfer_build (Value Transfer API steps). Returns the transaction hash on success. The caller must construct calldata, sign locally with msg.value = nativeFee from the corresponding quote tool, then submit the RLP-encoded signed tx hex here.

Input parameters:

- `signed_tx_hex` (string, required): Pre-signed Ethereum transaction in hex format (the 0x-prefixed RLP-encoded signed transaction). Construct calldata via lz_send_message / lz_oft_send / lz_stargate_send / lz_transfer_build, sign local…
- `src_chain` (string, required): Source chain name (e.g. 'ethereum', 'arbitrum', 'base', 'optimism', 'polygon', 'avalanche', 'bsc')

Output parameters:

- `result`: Underlying response payload verbatim.

### `lz_encode_options` (~141 tokens)

Encode LayerZero TYPE_3 options bytes for use with EndpointV2.quote() and EndpointV2.send(). TYPE_3 (version tag 0x0003) is the current standard options format for LayerZero V2.
