Trust breakdown (7 categories)

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. How we score → Why this is hard to score →

Supply Chain Security98
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency19
Schema Quality & AI Usability76
  • AI-judged instruction clarity (good).Pass
  • 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. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management47
  • Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "get_contract_transfer_tokens" implies "transfer" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 83 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
Install

How do I install the Voyager Starknet Explorer MCP server?

Voyager Starknet Explorer runs locally as an npm package, launched with npx -y voyager-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 82 exposed · ~8,216 tokens

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 →

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.
