Proposal
ChatGPT, Grok, or another MCP client requests a capability.
THE PERMISSION LAYER BETWEEN AI AND YOUR DEVICES
AI coordinates.
You control.
Kyntral lets AI systems request narrow, revocable capabilities while your paired device remains the execution authority.
v0.1 RC · not yet a production service
Authorization
Kyntral checks principal, paired device, scope, workflow, risk, expiry, and grant.
Execution
The paired device verifies the signed action and performs the approved local work.
Verification
A device-signed receipt is bound to the exact authorized action.
LOCAL-FIRST PRIVACY
Capabilities without custody.
Kyntral Cloud should not need Notes text, source URLs, media bytes, clipboard contents, or destination filenames to authorize a local workflow. The control plane handles opaque authority metadata; private workflow inputs stay on the device whenever possible.
FOR DEVELOPERS
Portable capability contracts.
Protocol schemas, conformance vectors, and the protocol-facing SDK are designed for interoperability. Capability manifests declare requirements; they never grant themselves authority.
