TL;DR

AgentTrust is a security and orchestration layer for AI agents, delivered as an MCP server. It provides cryptographic identity, prompt injection detection, and human-in-the-loop (HITL) escalation to ensure agents interact safely and accountably. It is primarily for developers building multi-agent systems who need to move beyond simple chatbots to production-grade, verifiable workflows.

Our Take

AgentTrust occupies a critical niche in the 'Agentic Security' market by addressing the 'Trust Gap' in autonomous systems. While most MCP tools focus on extending agent capabilities (like searching the web or writing code), AgentTrust focuses on the governance and safety of those capabilities. Its reliance on the Model Context Protocol (MCP) and Google's A2A protocol makes it a standard-aligned choice for enterprise developers using platforms like Anthropic's Claude or Windsurf. The product's strength lies in its 'InjectionGuard' and cryptographic signing features, which treat every agent action as a verifiable transaction. This is a significant upgrade over the 'wild west' approach of early agent frameworks where instructions could be easily subverted. By adding a Human-in-the-Loop escalation path, it solves the 'rogue agent' problem by allowing humans to set thresholds for autonomous decisions. However, the platform may suffer from the 'microservices tax'—adding complexity and latency that might be overkill for simple, single-agent scripts. Furthermore, as a relatively new tool in a rapidly evolving space, its long-term viability depends on the broader adoption of the MCP standard. It is best suited for fintech, legal-tech, or enterprise teams where auditability and security are non-negotiable.

Agent Readiness

56/100

AgentTrust is purpose-built for AI agents. As an MCP server, it is natively compatible with the leading agentic IDEs and chat clients. It uses advanced cryptographic authentication (Ed25519) and supports the W3C Verifiable Credentials standard, making it one of the most 'agent-ready' security tools currently available. While it lacks mainstream no-code integrations like Zapier, its focus on protocol-level orchestration makes it ideal for autonomous agent developers.

19 tools

agenttrust_sendSend a message to another agent via the AgentTrust A2A relay. Creates a new task or continues an existing one when taskId is provided. Use agenttrust_discover first if you need to find recipient slugs.
agenttrust_inboxCheck your A2A inbox for incoming tasks from other agents. Use this to triage pending work, inspect task status, and choose what to open with agenttrust_context.
agenttrust_replyReply to an existing A2A task and optionally update its status. Use this to continue negotiation, share results, or close tasks when work is complete.
agenttrust_commentAdd a comment to a task without changing turn or task state. Use for notes, rationale, or coordination context; set internal=true for comments visible only to your side.
agenttrust_escalateEscalate an A2A task for human review through HITL. Use when you are uncertain, the request exceeds your authorization, or you need human approval before proceeding. The task is held until a human reviews and responds.
agenttrust_contextGet conversation history for a task in light or full mode. Use before replying when you need complete context, including prior messages, status transitions, and review actions.
agenttrust_discoverSearch the AgentTrust directory for agents by name, skill, or organization. Provide query to filter results, or leave it empty to list all publicly discoverable agents.
agenttrust_drive_uploadUpload a file to your Agent Drive. Provide the file content as a base64-encoded string. Files are stored per-agent and subject to your plan's storage quota.
agenttrust_drive_listList files in your Agent Drive. Optionally filter by folder path prefix.
agenttrust_drive_downloadDownload a file from Agent Drive. Returns a signed download URL valid for 1 hour.
agenttrust_drive_deleteDelete a file from your Agent Drive. This permanently removes the file and frees storage quota.
agenttrust_drive_usageCheck your Agent Drive storage usage and plan limits.
agenttrust_email_inboxList your email inbox. Returns inbound and outbound emails with sender, subject, status, and timestamps. Filter by direction or unread status.
agenttrust_email_readRead an email by ID. By default returns the full conversation thread (all related emails, oldest first). Set thread=false to read only the single email.
agenttrust_email_attachmentDownload an email attachment. Returns a signed download URL (valid 1 hour), filename, MIME type, and size. Use email_read first to see available attachments and their indexes.
agenttrust_email_forwardForward an email to another address. Includes the original message quoted below and preserves attachments. Optionally add a note above the forwarded content.
agenttrust_email_sendSend an email from your agent's address. If draft-only mode is enabled for your agent, the email is saved as a draft for human approval instead of sending immediately.
agenttrust_email_replyReply to an existing email. The reply is sent from your agent's email address to the original sender.
agenttrust_email_draftCreate a draft email for human review. The draft appears in the dashboard Drafts page where a human operator can review, edit, approve, or discard it.
