## Trust breakdown

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)

Scored 2026-11-05.

- **Supply Chain Security**: 99/100
  - No malware found by supply-chain analysis.
  - Known CVEs were checked across the 94 of 95 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - Dependency health was assessed across the 94 of 95 dependencies we could resolve, so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 87/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to jaggernaut007/nexus-mcp).
  - License check failed: the license (PolyForm-Noncommercial-1.0.0) isn't a recognized OSI-approved license.
  - Actively maintained (last published 1 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: our sandbox could not run this package, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: our sandbox could not run this package, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: our sandbox could not run this package, so we have no tool definitions to assess.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: our sandbox could not run this package, so we have no tool text to scan.
- **Capabilities**: 0/100
  - Protocol version not yet verified: our sandbox could not run this package, so we never saw its MCP handshake.

**Unverified: 5 categories.** Categories scored 0 because our sandbox could not run this package, so we have no schema for these checks to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until we can run it.

## Common questions

### What is the Nexus-MCP server?

Nexus-MCP is listed in the public MCP registry as io.github.jaggernaut007/nexus-mcp. Local code-intelligence server: hybrid code search, call graph and project memory. This page covers its PyPI package (nexus-mcp-ci).

### Is the Nexus-MCP server safe to use?

Nexus-MCP scores 47 out of 100 on VerifyMCP. Its build provenance is signed and verified. 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.

### Is the Nexus-MCP server still maintained?

Nexus-MCP is still listed as active in the MCP registry. We last reached this channel on 5 November 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 Nexus-MCP server under?

Nexus-MCP declares the PolyForm-Noncommercial-1.0.0 licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.
