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.

- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 904 tokens (~50/item across 18 items; 18 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.

## Common questions

### What is the Block Genomics — Nexus Protocol MCP server?

Block Genomics — Nexus Protocol is an MCP server listed in the public MCP registry as io.github.BitmapAsset/block-genomics-mcp. Prove Bitcoin block ownership via BIP-322 and register sovereign AI agents on the Nexus Protocol. This page covers its npm package (block-genomics-mcp).

### Is the Block Genomics — Nexus Protocol MCP server safe to use?

Block Genomics — Nexus Protocol scores 82 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 Block Genomics — Nexus Protocol MCP server expose?

Block Genomics — Nexus Protocol exposes 18 tools: bg_stats, bg_search, bg_block, bg_ownership_verify, bg_agents_by_block, and 13 more. Their descriptions and schemas cost roughly 904 tokens of context every time the server is loaded.

### Is the Block Genomics — Nexus Protocol MCP server still maintained?

Block Genomics — Nexus Protocol 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 Block Genomics — Nexus Protocol MCP server under?

Block Genomics — Nexus Protocol declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
