SDKs - NeuralTrust Docs | TrustGate, TrustGuard, TrustTest

NeuralTrust publishes two SDKs. They solve different problems, and many applications use only one of them.

	TrustGate SDK	TrustGuard SDK
What it does	Connects your code to a TrustGate application: its MCP tools, its models, and the end users it acts for	Sends a prompt, a completion or a tool call to TrustGuard and returns a verdict your code enforces
Use it when	Your agent calls tools and models through TrustGate	Your code sits in the data path and must apply a policy itself
Credential	The application’s key (`ag_…`)	A collector key (`tgk_…`)
Who enforces	The gateway, on every call it serves	Your code, on the verdict
Python	`pip install trustgate-sdk` (Python 3.10+)	`pip install trustguard-sdk`
TypeScript	`npm install @neuraltrust/trustgate` (Node.js 22+)	`npm install @neuraltrust/trustguard-sdk`
Go	—	`github.com/NeuralTrust/trustguard-sdk/go`
Packages	PyPI · npm	PyPI · npm · pkg.go.dev
Source	NeuralTrust/trustgate-sdk	NeuralTrust/trustguard-sdk

When a TrustGuard policy is attached to the gateway, traffic that goes through TrustGate is already evaluated there, so an agent built on the TrustGate SDK does not also need the TrustGuard SDK for those calls. Reach for the TrustGuard SDK for content that never passes through a gateway: a model you call directly, a document you index, a reply you generate.

For route-level coverage without a call at each site, the Python and Node.js middleware wrap the TrustGuard SDK. From any other language, call the Evaluate API directly.
