The free tier is 1,000 detect calls + 10 canon scans per month — enough to ship a real product, not just kick the tires.\n\n**Pricing** [→ mcp.viridis-security.com/pricing](https://mcp.viridis-security.com/pricing) · **Sign up** [→ /signup](https://mcp.viridis-security.com/signup) · **SDK** [→ github.com/viridis-security/mcp-services-sdk](https://github.com/viridis-security/mcp-services-sdk)\n\n---\n\n**Aristotle-verified attribution-enforcement primitives for AI agents.**\n\nThis is the public, open-source SDK for the [Viridis MCP](https://mcp.viridis-security.com) services. The hosted service implementation is proprietary; this repo contains everything you need to integrate.\n\n> 🆕 **Reference implementation of MCP-10 Maxwell is now in this repo** — Apache-2.0, theorem-backed, runnable in <1 minute. Adaptive proof-of-work defense that makes AI-spam pay the energy bill instead of your triagers.

See the [corpus paper](https://github.com/viridis-security/corpus) (forthcoming) for proofs.\n\n## Quick start\n\n```bash\n# 1.

This mirrors the standard playbook: the *interface* is open (so anyone can build against it without legal review or vendor lock-in), the *implementation* is the moat.\n\n## Open-source policy\n\nApache-2.0. You can use, modify, redistribute, fork — no obligation to share changes back, but PRs are welcome.\n\nThe SDK source under `sdk/` is the canonical implementation. Examples under `examples/` are copy-paste-friendly. Service documentation under `services/` is the official API reference for the corresponding hosted endpoints.\n\n## Links\n\n- **Live service:** <https://mcp.viridis-security.com>\n- **API docs:** <https://mcp.viridis-security.com/docs>\n- **Terms of Service:** <https://mcp.viridis-security.com/terms>\n- **Privacy Policy:** <https://mcp.viridis-security.com/privacy>\n- **Corpus paper:** <https://github.com/viridis-security/corpus> (forthcoming)\n- **Maintained by:** [Viridis North LLC](https://viridis-security.com)\n\n## Maintainers\n\nMaintained by Viridis North LLC.
