This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
ANTHROPIC_API_KEYRequired, secret | Your Anthropic API key (sk-ant-...). Required for the claim extractor, red team, constitution engines, and ECS coherence checks. One v1 tool (generate_trust_card) works without an API key — it's pure assembly + deterministic audit hashing. |
GLASSBOX_MODELOptional | Override the Claude model used by the verification engines. Defaults to claude-sonnet-4-6. |
GLASSBOX_MAX_TOKENSOptional | Per-engine-call max-tokens cap. Defaults to 2048; raise for verifying long-form content. |
GLASSBOX_ECS_MODEOptional | ECS aggregation mode: arithmetic (weighted mean, default) or geometric (stricter — any zero dimension collapses the total). |
