Looking for an alternative to Delego? Whether you need a different runtime environment, custom authentication support, or alternative API integrations in the Security ecosystem, we have cataloged and compared the top alternative MCP servers below.
Delego sits between an AI agent and whatever credential broker holds a user's secrets, checking whether a specific proposed action actually matches what the human asked for — not just whether the agent's credential scope allows it. It implements protocol 0.3 of the open Delego wire specification, including policy evaluation, intent/fingerprint binding, and a signed audit chain, with human-in-the-loop approval for actions that need it. This targets the confused-deputy problem: an agent redirected by prompt injection can still hold a technically valid credential, so authorizing the credential alone isn't enough.
Primary Use Cases for Delego:
Gate agent actions against a policy engine before a credential broker executes them
Require human approval for actions flagged as sensitive or out-of-policy
Maintain a signed, tamper-evident audit trail of every authorized agent action
Bind a proposed action to the user's original intent to block prompt-injection redirects
