ctrlrun vs kru
ctrlrun: CTRLRun ensures execution safety for AI agents by acting as a critical check between an agent's decision and the actual call. It enforces strict policies to prevent unintended actions, duplicate effects, and ambiguous outcomes, providing auditable receipts for every interaction.; kru: KRU is a free, open-source, local-first credential manager and MCP server designed for AI agents. It enables agents to securely use passwords, API keys, and SSH credentials for various tasks without exposing plaintext to the model context.

Features
ctrlrun01Approval binding to exact actions, refusing mutated or replayed ones.
02Ensures one logical effect happens at most once, across threads, processes, and hosts.
03Distinguishes unknown outcomes (AMBIGUOUS) from failures, blocking blind retries.
04Generates portable JSON receipts for every executed action, recording who, what, and outcome.
05Applies a fail-closed policy, denying unknown actions, missing policies, or principals by default.
kru01Local Encrypted Credential Vault: Stores sensitive data (passwords, API keys, SSH keys, TOTP) locally, encrypted with XChaCha20-Poly1305, without requiring a cloud account.
02AI Agent Credential Relay (MCP Server): Functions as a local stdio MCP server, allowing AI agents to perform authenticated actions without exposing plaintext secrets to the model context.
03Flexible Credential Item Modules: Supports customizable credential items by combining various modules (username, password, API key, SSH key, TOTP, host, URL, custom fields).
04Cross-Platform & Portable: Available on Windows, macOS, and Linux, with portable builds and no installation/registration required.
05Diverse Credential Actions: Enables agents to perform actions like browser field filling, SSH command execution/file transfer, and authenticated HTTP requests.

Use Cases
ctrlrun↳Managing infrastructure deployments and operations in DevOps, ensuring changes are approved and auditable.
↳Enforcing security policies like firewall rules or disabling protection, with strict human oversight for critical actions.
↳Handling financial transactions such as refunds, ensuring amounts are within policy and preventing double refunds.
↳Controlling Identity and Access Management (IAM) operations like granting roles, preventing unauthorized privilege escalation.
kru↳Automate Server Operations: AI agents can securely connect to servers via SSH to deploy builds or verify services using saved credentials.
↳Integrate with Authenticated APIs: Agents can make authenticated API calls (e.g., to DNS providers) without exposing API keys directly.
↳Streamline Browser Sign-ins: Automate browser login processes by having agents use saved credentials to fill form fields and submit them.
↳Secure Terminal Command Execution: Allow agents to run local or remote terminal commands with hidden modules substituted for sensitive arguments.
↳Managed File Transfers: Agents can securely upload or download files and directories over SFTP using their saved SSH identities.
