## 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**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 0 of 32 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to sipkigroup/witness).
  - Clear OSI-approved license (Apache-2.0).
  - 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: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to assess.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no schema to compare.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool definitions to assess.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we have no tool text to scan.
- **Capabilities**: 0/100
  - Protocol version not yet verified: this server's registry entry declares environment variables (an API key or similar), and its server did not start in our sandbox, so we never saw its MCP handshake.

**Unverified: 5 categories.** Categories scored 0 because our sandbox has not given us the schema these checks need 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 the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## Install

### How do I install the Deus Witness MCP server?

Deus Witness runs locally as a PyPI package, launched with uvx deus-witness --, plus the required upstream_command, which you supply. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

### Claude

```bash
claude mcp add sipkigroup-witness -- uvx deus-witness --
```

Incomplete: the registry marks upstream_command as required and gives no value we can show, so it is not in this command. Add it before you run it.

### Cursor

  "mcpServers": {
    "sipkigroup-witness": {
      "command": "uvx",
      "args": [
        "deus-witness",
        "--"
      ]
    }
  }
}
```

Incomplete: the registry marks upstream_command as required and gives no value we can show, so it is not in this command. Add it before you run it.

### VS Code

```json
{
  "servers": {
    "sipkigroup-witness": {
      "command": "uvx",
      "args": [
        "deus-witness",
        "--"
      ]
    }
  }
}
```

Incomplete: the registry marks upstream_command as required and gives no value we can show, so it is not in this command. Add it before you run it.

### Codex

```bash
codex mcp add sipkigroup-witness -- uvx deus-witness --
```

Incomplete: the registry marks upstream_command as required and gives no value we can show, so it is not in this command. Add it before you run it.

### opencode

  "mcp": {
    "sipkigroup-witness": {
      "type": "local",

```

## Common questions

### What is the Deus Witness MCP server?

Deus Witness is an MCP server listed in the public MCP registry as io.github.sipkigroup/witness. MCP proxy: holds risky tool calls for passkey approval; signed receipts you can check offline. This page covers its PyPI package (deus-witness).

### Is the Deus Witness MCP server safe to use?

Deus Witness scores 35 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. 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 Deus Witness MCP server still maintained?

Deus Witness 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 Deus Witness MCP server under?

Deus Witness declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Deus Witness MCP server?

VerifyMCP ran 8 checks on Deus Witness, covering Known CVEs, Install scripts, Dependency health, Source repository and 4 more. 6 items could not be completed, a gap on our side rather than a finding about Deus Witness: Malware scan, Schema quality, Stability, Tool coverage and 2 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
