About

Kastra is the authorization layer for AI systems, deciding what agents, models, and AI tools are allowed to do before they do it. It sits in the execution path of every prompt, tool call, shell command, database operation, and API request, evaluates each action against deterministic, attribute-based policy, and returns an allow, deny, redact, or escalate decision in under a millisecond. Unlike monitoring products that observe AI after it acts, Kastra blocks unauthorized behavior before it reaches a tool, API, database, or production system. Its unified control plane combines a policy engine, edge decision points, integrations, and a tamper-evident evidence vault that signs every decision for audit and replay. Kastra Edge brings local enforcement to developer machines, protecting Claude Code, Cursor, Codex CLI, and other coding agents from destructive commands, secret exfiltration, unsafe file writes, and unauthorized tool use.

About

SEAOTTER is a managed control plane for Hermes Agent on Google Cloud. Isolated, always-on agents. No VPS. No SSH. You create an agent in the dashboard. SEAOTTER provisions a per-agent namespace with a gVisor sandbox, typically in a few minutes. Pause, restart, restore, and reprovision from the API or UI. Logs and metrics included. You do not SSH into a box. Secrets go in a write-only tab and are stored in Google Secret Manager. Hermes loads them at startup. Do not paste keys into chat. After signup, connect with an org-scoped so_ MCP key from Cursor, Claude, or Codex. Hermes is the live harness: tools, memory, cron. us-central1 is live. 7-day trial, no credit card, one agent only (1 CPU / 4Gi / 8Gi). Then $99 per always-on agent / month. Extra agents after convert at +$99. Custom is book-a-call.

Audience

AI engineering and security teams that need to enforce authorization policies and audit every action performed by AI systems before execution

Audience

Builders, operators, and small teams who want always-on Hermes Agent without running a VPS. Builders: people who already use Hermes (or want to) and need one standing agent for tools, memory, and cron. They close the laptop and the agent stays up. No ops hire. Operators: people who would otherwise SSH into a box to pause, restart, restore, or rotate keys. They want lifecycle from a dashboard and API, secrets in Google Secret Manager, and MCP from Cursor, Claude, or Codex. Teams: groups that outgrew a single laptop or a cheap VPS and want the same managed plane for more than one isolated agent after they convert from trial. Isolation is per agent from day one; it does not wait for an Enterprise SKU. Not the audience: agencies as a landing ICP, generic “host any agent” shoppers, or anyone looking for OtterScore / seaotter.ai. Custom / larger orgs can book a call. Industries are not locked. Fit is the job: keep open-source Hermes online without owning Linux, Docker, or SSH.
