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 95 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency6
Schema Quality & AI Usability89
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 5590 tokens (~65/item across 85 items; 83 tools + 2 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
  • Stability observed for 27 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 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "agent_send_message" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail

MCP tools · 83 exposed · ~5,563 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 io.github.EmperorMew/voidly-mcp-server server?

io.github.EmperorMew/voidly-mcp-server is listed in the public MCP registry as io.github.EmperorMew/voidly-mcp-server. 83 tools: censorship intelligence (119 countries) + E2E encrypted agent messaging. This page covers its npm package (@voidly/mcp-server).

Is the io.github.EmperorMew/voidly-mcp-server server safe to use?

io.github.EmperorMew/voidly-mcp-server scores 76 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 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 io.github.EmperorMew/voidly-mcp-server server expose?

io.github.EmperorMew/voidly-mcp-server exposes 83 tools: get_censorship_index, get_country_status, check_domain_blocked, get_most_censored, get_active_incidents, and 78 more. Their descriptions and schemas cost roughly 5,563 tokens of context every time the server is loaded.

Is the io.github.EmperorMew/voidly-mcp-server server still maintained?

io.github.EmperorMew/voidly-mcp-server is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
