Evaluation Context Protocol (ECP) vs NodePad

ECP is a vendor-neutral JSON-RPC protocol for grading agent outputs, tool calls, and audit context across frameworks, models, and CI systems.

Agent on canvas. NodePad lays your AI conversations out on a canvas, so you try more ideas, keep the answers that hold up, and never lose the thread that mattered.

About Evaluation Context Protocol (ECP)

ECP is a vendor-neutral JSON-RPC protocol for grading agent outputs, tool calls, and audit context across frameworks, models, and CI systems. ECP gives evaluators a common way to inspect what an agent returned, what tools it used, and what audit evidence it exposed, independent of the framework that built the agent or the platform that runs the test. tool_calls Did the agent call the required tool with the right arguments?. ecp run --manifest Can this run in CI and fail a build?.

About NodePad

Agent on canvas. NodePad lays your AI conversations out on a canvas, so you try more ideas, keep the answers that hold up, and never lose the thread that mattered. You can then use the arrow keys to move the node around. You can then press delete to remove it or escape to cancel. Every message on a NodePad canvas is a node you can build on, and the model only ever sees the context you chose.
