Create a conda env

conda create -n WAP python=3.11

Activate the conda env

conda activate WAP

Install the dependencies

pip install -r requirements.txt

Setup your repo source path:

set PYTHONPATH=C:/path/to/webagentprotocol # for Windows
export PYTHONPATH=/path/to/webagentprotocol # for Linux

Create .env file under the repo root directory with your own API keys:

OPENAI_API_KEY=sk-proj-...
DEEPSEEK_API_KEY=sk-...

Record

WAP record extension

Please refer to OTA‑WAP Chrome Extension to setup action capturer in your Chrome browser.

Start data‑collection server

Run the following command to start the server to collect data from the extension:

python action_collect_server.py

Once the server is up, you can start to record from the page using WAP Chrome extension.

The server listens on http://localhost:4934/action-data by default, please make sure the Host and Port in the extension settings match this server config. Each session will be saved to:

data/YYYYMMDD/taskid/summary_event_<timestamp>.json

An example of the formatted data which you will received in the WAP backend server is like:

{
  "taskId": "MkCAhQsHgXn7YgaK",
  "type": "click",
  "actionTimestamp": 1746325231479,
  "eventTarget": {
    "type": "click",
    "target": "<a ota-use-interactive-target=\"1\" data-ordinal=\"3\" href=\"https://www.allrecipes.com/recipe/68925/cheesy-baked-salmon/\" data-tax-levels=\"\" data-doc-id=\"6592066\" class=\"comp mntl-card-list-card--extendable mntl-universal-card mntl-document-card mntl-card card card--no-image\" id=\"mntl-card-list-card--extendable_3-0\">\n<div class=\"loc card__top\"><div class=\"card__media mntl-image card__media universal-image__container\">...",
    "targetId": "mntl-card-list-card--extendable_3-0",
    "targetClass": "comp mntl-card-list-card--extendable mntl-universal-card mntl-document-card mntl-card card card--no-image"
  },
  "allEvents": {},
  "pageHTMLContent": "<header data-tracking-container=\"true\" data-collapsible=\"true\" class=\"comp header mntl-header mntl-header--magazine mntl-header--open-search-bar mntl-header--myr\" id=\"header_1-0\"><a data-tracking-container=\"true\" id=\"mntl-skip-to-content_1-0\" class=\"mntl-skip-to-content mntl-text-link\" rel=\"nocaes\" href=\"#main\"></a><div class=\"mntl-header__menu-top\">..."
}

Generate replay lists

| Mode | Command | | -------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Exact replay – exactly reproduce every action | python wap_replay/generate_exact_replay_list.py --data_dir_path data/<date>/<task_id> --output_dir_path data_processed/exact_replay | | Smart replay – condensed goal‑oriented steps | python wap_replay/generate_smart_replay_list.py --data_dir_path data/<date>/<task_id> --output_dir_path data_processed/smart_replay |

Replace <task_id> with the folder produced by the extension (e.g. em3h6UBDZykz0gnH).

Output structure:

data_processed/smart_replay/
 ├─ subgoals_<task_id>/                     # intermediate prompts & replies
 └─ wap_smart_replay_list_<task_id>.json   # final smart replay list for the agent

data_processed/exact_replay/
 └─ wap_smart_replay_list_<task_id>.json   # final exact replay list for the agent

Replay

python run_replay.py --model-provider openai --wap_replay_list data_processed/exact_replay/wap_exact_replay_list_<task_id>.json --max-concurrent 1

For smart-replay, replace the path with a smart‑replay JSON to test this mode.

Convert to MCP Server

python wap_replay\generate_mcp_server.py --task_id <task_id>

converted MCP servers will be located under mcp_servers folder

Replay with MCP

You would need 2 terminals to replay with MCP. In the first termnial

python wap_service.py

In the second termnial

python mcp_client.py

Then enter your prompt in the second terminal

example: find a top rated keyboard on amazon.ca using smart replay

Replay with our Desktop App

We provide out-of-box desktop app for running replay lists. It is easy to install and you don't need any extra steps for setup and deployments. Visit WAP Replay Tool releases for more details.

Troubleshooting

ModuleNotFoundError – run commands from the project root or export PYTHONPATH=. (set PYTHONPATH=. for Windows).

“no task‑start file” – ensure the extension recorded a full session; the generators require exactly one task-start and one task-finish record.
