## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 416 tokens (~208/item across 2 items; 1 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Atlas Primer Voice Roleplay MCP server?

Atlas Primer Voice Roleplay is a hosted endpoint at https://roleplay.atlasprimer.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

      "enabled": true
    }
  }
}
```

### OpenClaw

```bash
openclaw mcp add atlasprimer-mcp-server --url 'https://roleplay.atlasprimer.com/mcp' --transport streamable-http
```

### Hermes

```yaml
mcp_servers:
  atlasprimer-mcp-server:
    url: "https://roleplay.atlasprimer.com/mcp"
```

### Netclaw

    }
  }
}
```

### Vellum

```bash
assistant mcp add atlasprimer-mcp-server -t streamable-http -u 'https://roleplay.atlasprimer.com/mcp'
```

### Other

```json
{
  "mcpServers": {
    "atlasprimer-mcp-server": {
      "type": "http",

Create Voice Roleplay Simulation

Creates a personalized real-time AI voice roleplay simulation on Atlas Primer from a natural-language scenario description. Returns a direct, clickable simulation URL requiring no API keys or pre-registration.

Input parameters:

- `challenge_keywords` (string): 3 to 4 comma-separated behavioral resistance traits (e.g., "skeptical, defensive, budget-constrained").
- `character_gender` (string): Speech synthesis voice gender ("male" or "female").
- `character_name` (string): Counterpart name and title (e.g., "Elena Rostova, VP of Procurement").
- `character_role` (string): Counterpart functional role or authority level.
- `failure_criteria` (string): Single sentence defining what triggers conversation failure.
- `language` (string): ISO-639-1 language code such as "en", "is", "es", or "ja" (default: "en").
- `max_duration_minutes` (number): Maximum duration in minutes between 3 and 30 (default: 10).
- `prompt` (string, required): Full 1-paragraph scenario description defining who the user is, who the counterpart is, the core conflict or disagreement, and the stakes.
- `success_criteria` (string): Single unambiguous sentence defining measurable conversation success.
- `user_role` (string): Learner role and perspective (e.g., "Senior Account Executive").

Output parameters:

- `encoded_token` (string): Base64URL-encoded JSON scenario token.
- `payload` (object): Sanitized simulation payload parameters.
- `query_url` (string): Fallback clickable simulation URL using plain query parameters (?prompt=...).
- `url` (string): Primary clickable simulation URL using Base64URL fragment (#d=...).
