How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 8500 tokens (~103/item across 82 items; 82 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.

## Common questions

### What is the Voyager Starknet Explorer MCP server?

Voyager Starknet Explorer is an MCP server listed in the public MCP registry as online.voyager/mcp. Live Starknet explorer data: transactions, contracts, tokens, NFTs, staking. This page covers its npm package (voyager-mcp).

### Is the Voyager Starknet Explorer MCP server safe to use?

Voyager Starknet Explorer scores 70 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. 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 Voyager Starknet Explorer MCP server expose?

Voyager Starknet Explorer exposes 82 tools: voyager_ping, list_transactions, get_transaction, get_transaction_trace, get_transaction_messages, and 77 more. Their descriptions and schemas cost roughly 8,216 tokens of context every time the server is loaded.

### Is the Voyager Starknet Explorer MCP server still maintained?

Voyager Starknet Explorer is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Voyager Starknet Explorer MCP server under?

Voyager Starknet Explorer declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
