Replayable autonomous tool execution — lightweight trust infrastructure SDK

ToolTrust SDK

Replayable autonomous tool execution.

ToolTrust is a lightweight trust infrastructure SDK for autonomous systems and agent tooling. Wrap tools in minutes and generate replayable trust artifacts (DDCs), local ATP trust history, verifier-readable execution records, and machine-readable provenance for autonomous actions.

ToolTrust is designed to work with existing agent frameworks and orchestration systems without requiring a rewrite of your stack.

Quick Example

from tooltrust import tool, LocalToolTrustClient

client = LocalToolTrustClient()

@tool(risk="code_execution")
def greet(name: str):
    return f"Hello {name}!"

result = client.execute(greet, "Ardyn")

print(result.output)
print(result.ddc_id)

Result:

Hello Ardyn!
DDC: ddc-f7b7bce8be01

What Is a DDC?

A DDC (Data Destruction Certificate) is a replayable trust artifact describing an autonomous execution event.

DDCs can contain:

• tool invocation metadata
• input/output hashes
• verifier signatures
• replay provenance
• execution lineage
• trust metadata

ToolTrust generates local DDCs by default. Production-grade sovereign certification, ATP persistence, verifier replay, anchoring, and governance are available through Ardyn infrastructure.

Risk Classes

ToolTrust supports built-in risk classification:

• read_only
• data_access
• write_action
• external_communication
• code_execution
• infrastructure_mutation
• financial_action
• regulated_data_action

---

Adapters

ToolTrust integrates with existing ecosystems:

• MCP
• LangChain
• CrewAI
• HTTP tools
• shell/code execution

The goal is simple:

Wrap the tool call, not the entire agent stack.

---

Local Mode

ToolTrust works fully offline in local mode:

• local DDC chain
• local ATP-lite
• local verifier
• local replay
• no cloud dependency
• no billing

---

Relay / Production Mode

ToolTrust can optionally relay trust events into Ardyn sovereign trust infrastructure for:

• production DDC issuance
• ATP persistence
• verifier replay
• organization governance
• sovereign evidence
• Bitcoin anchoring
• CertificationGate trust enforcement

---

Machine-Readable Provenance

Every exported trust artifact includes provenance metadata:

{
  "issuer": "Ardyn Intelligence Systems",
  "verification_provider": "Ardyn Verified",
  "trust_substrate": "Ardyn Tool Trust",
  "verification_url": "https://api.ardyn.ai"
}

---

Philosophy

ToolTrust is not another agent framework.

It is a trust infrastructure layer for autonomous tools and actions.

The SDK is intentionally lightweight:

• install in minutes
• wrap existing tools
• preserve existing workflows
• add replayable trust semantics
