ECP is a vendor-neutral protocol for testing agent outputs, tool calls, and evaluator-visible audit context across frameworks, models, eval platforms, and CI systems.

Install

pip install "ecp-runtime==0.7.0"

Usage

ecp init
ecp validate ecp_eval/manifest.yaml
ecp run --manifest ecp_eval/manifest.yaml --json

Run the flagship example:

ecp run --manifest examples/customer_support_demo/manifest.yaml --report report.html

Useful commands:

ecp validate examples/customer_support_demo/manifest.yaml
ecp conformance --target "python examples/customer_support_demo/agent.py"
ecp doctor

Manifest target values may be either a command for the default stdio transport or an ECP Streamable HTTP endpoint:

target: "http://127.0.0.1:8765/ecp"

If your manifest includes llm_judge, set an API key and optional judge model:

$env:OPENAI_API_KEY="your_key_here"
$env:ECP_LLM_JUDGE_MODEL="gpt-4o-mini"
