About Bluebear
Bluebear is the security control plane for AI coding agents. We give security, engineering, and platform teams real-time visibility and contextual control over what agents access, execute, and change at runtime, on the developer endpoint, before code, build, and deployment protections ever see it.
The problem we work on
Coding agents are no longer chatbots. Claude Code, Cursor, Codex, Copilot, Antigravity, and Gemini run Bash, call MCP servers, edit files, install dependencies, and hit cloud APIs inside trusted employee environments, with the developer’s inherited access to code, secrets, and systems.
Traditional controls were not built for this. EDR sees a process, AppSec sees a diff, IAM sees a user, an LLM gateway sees a prompt. None of them see the mandate the agent was given, the tool-call chain it produced, or the runtime context an action executes in.
That leaves organizations with a false choice: allow agents freely and absorb the risk, or restrict them and fall behind. When you have guardrails on a bridge, you can run.
How we approach it
- Visibility. An endpoint handler wraps agent sessions where the work happens and records every tool call, command, file edit, package install, and MCP invocation.
- Control. Policy evaluates each action against the user’s mandate, the target environment, and the credentials in scope, then allows, sandboxes, scopes down, or routes to a human for approval.
- Least privilege that developers can live with. Ephemeral identities, microVM isolation, and dynamic access control reduce exposure from data leaks, destructive actions, and prompt injection without slowing anyone down.
- Supply-chain hygiene. We inventory and rate the skills, plugins, and MCP servers agents load, including slopsquatted packages that do not exist until an agent invents them.
