Agts MCP Server

AGTS MCP Server

Sovereign MCP Gateway — Governed Tool Invocation for Autonomous Agents

Model Context Protocol server that turns tool calls into cryptographically authorized, verifiable actions. 64 governed tools across 6 layers — hybrid Ed25519 + SLH-DSA signed and Merkle-anchored. Designed to support EU AI Act, GDPR, SOC 2, ISO 27001, DORA, NIS2, and FINRA compliance.

Authentication

The gateway requires a Bearer token issued through the ObligationSign platform. All requests must include an Authorization header.

To obtain a token, register at obligationsign.com/start/.

Quick Start

Claude Desktop / Cursor / Windsurf

Add to your MCP configuration:

{
  "mcpServers": {
    "agts": {
      "url": "https://agts-mcp.obligationsign.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Programmatic (JSON-RPC over HTTP)

curl -X POST https://agts-mcp.obligationsign.com/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list",
    "params": {}
  }'

What is AGTS?

AGTS (Autonomous Governance Transparency Standard) is a transparency-backed governance protocol that converts validated machine decisions into append-only cryptographic records, independently verified by a network of witnesses and monitors.

decision → record → immutable history → verifiable truth

Every tool call passes through a five-gate firewall (Statistical, Causal, Regression, Evidence, Human-Compatible Explanation) before execution. Admitted actions are Merkle-anchored into an append-only transparency log and signed with hybrid post-quantum cryptography.

How This Server Differs

Most MCP servers in the ecosystem (~83%) are thin API wrappers — a single connector exposed as one or two tools, running locally via stdio, with no authentication or validation. The production-tier servers from vendors like GitHub, Slack, and AWS (~2%) are well-built but architecturally simple: they translate tools/call into API requests for their own service.

This server operates at a different level. It is not a wrapper around an external API — it implements a full governance protocol where:

• Every action must pass through five evaluation gates before execution is authorized
• Admitted actions are cryptographically signed (hybrid Ed25519 + SLH-DSA) and Merkle-anchored in an append-only transparency log
• Execution outcomes are traced back to their authorization, creating a closed governance loop
• Independent monitors verify log consistency through a gossip protocol, detecting equivocation or tampering
• Identity is handled through post-quantum cryptography (ML-DSA-44, ML-KEM-512) for forward security

The result is that every tool call produces independently verifiable cryptographic evidence of what was authorized, what was executed, and whether the outcome matched the authorization — the kind of audit trail required in regulated industries (financial services, healthcare, legal, critical infrastructure).

Regulatory Readiness

The gateway's architecture is designed to support compliance across multiple regulatory frameworks. The table below maps specific requirements to the AGTS features that address them.

EU AI Act

SOC 2

ISO 27001

DORA (Digital Operational Resilience Act)

GDPR

NIS2

FINRA

The closest comparable in the market is not another MCP server — it is what a regulated enterprise would build internally to control what their AI agents can do in production.
