Keep machine-specific configuration out of Git. +4. Check `codex mcp get eraser`. Start a new local Codex session if Eraser is not + in the current session's tool list. + +Codex supports local STDIO servers and per-tool approval settings in its +[official MCP documentation](https://modelcontextprotocol.io/). +Other tools can use `approve`: the server rejects form actions and sends until +a batch exists, and enforces that batch's scope afterward. + +Batches and retries are approved in Eraser, not in the MCP client. `begin_batch` +and `retry_action` only work after a person approves the preview, or the retry, +on the Automation page of the web UI or with `eraser mcp approve ` in a +terminal. A client that auto-approves every tool therefore cannot start a batch +or release a retry by itself. + +That separation has limits. `eraser mcp approve` refuses to run without a +terminal, and the web page only accepts a browser's same-origin form post, but +an agent that can run commands or drive your browser can still approve its own +batch. Don't give the agent a shell or browser for the same session, or keep +those tools on a prompt in your client. + +Use `--config /absolute/path/config.yaml` if the web UI uses a non-default +configuration. Use `--profile ` when several profiles exist; Eraser refuses +to guess. `--chrome-path` selects a nonstandard browser executable.

No +real SMTP, IMAP, or broker connections occur. The only HTTP destination allowed +for the fixtures is the demo's own loopback listener. + +`get_status` returns `demo_config_path`. To view the same results in Eraser, run: + +```bash +./eraser --config /path/returned/by/get_status/config.yaml serve --port 8081 +``` + +Keep the MCP process running while interacting with the demo forms. The data +and screenshots remain in the printed temporary directory after it ends, so +you can review them in the web UI; remove that directory when finished. A +restarted demo has a new directory and new local URLs. + +## Normal workflow + +Ask **“Handle my pending removal tasks.”** The agent should: + +1. Read status and pending tasks. Optionally scan new replies first. +2. Prepare explicit task IDs, and explicit broker IDs only when you also want + new removal emails. Show you the profile fields, destinations, and email + drafts returned by `prepare_batch`. +3. Ask the user to approve that preview. They approve it on the Automation page + in the web UI, or with `eraser mcp approve `, and you then call + `begin_batch`. Each approval starts one batch, expires after 15 minutes, and + covers only those tasks and email recipients in that profile. `eraser mcp + pending` lists previews waiting for approval. An approval cannot be spent by + a different preview or after the profile or broker settings change. +4. Open a task, inspect its text and controls, then fill/select or click using + references from the latest snapshot. Personal values can be filled by + `profile_field` without the agent inventing missing information. +5. After each click, record visible evidence of progress, acceptance, or a + problem. `get_screenshot` returns an MCP image for visual inspection. +6. End the batch after reporting completed tasks and those needing your help. + +Previews expire after 15 minutes. A batch can contain up to 100 explicit items +and have at most five browser sessions open. Settings or broker-list changes +require a new preview. Ending the batch, disconnecting STDIO, or restarting the +process closes its browsers and revokes authorization. Cookies and intermediate +form state live only for the current browser session. + +## Tools + +| Tools | Purpose | +| --- | --- | +| `get_status`, `list_brokers`, `list_tasks`, `get_task` | Inspect the selected profile, eligible brokers, task details, source replies, and previous attempts. Lists are paginated. | +| `prepare_batch`, `begin_batch`, `end_batch` | Preview explicit work, start it once approved in Eraser, and revoke authorization. | +| `scan_inbox` | Read the configured inbox and classify replies for the selected owner; never archive or open links. | +| `send_request` | Send one reviewed email through the existing sender, respecting manual mode, dry-run, cooldown, daily cap, and rate limit. | +| `open_task`, `observe_page`, `get_screenshot` | Open an approved form/link and inspect the persistent browser. Opening a confirmation URL can itself perform an action. | +| `browser_action` | `fill` a text field, choose a select option by value/text, set a checkbox/radio using `true`/`false`, or `click` a current control. No arbitrary JavaScript or selectors. | +| `record_result` | Save `progress`, `submitted`, `needs_user`, or `unknown` with evidence against the existing task. | +| `retry_action` | After a separate user approval, release an uncertain attempt for retry using its action key and either an approved `task_id` or `broker_id`. Accepted submissions cannot be released. | + +## Evidence, interruptions, and privacy + +Submission completes the **task**, not the data removal. An email send means +SMTP accepted a message. A form receipt means the request was accepted. Existing +pipeline records move to **Awaiting response** after form acceptance, never automatically to +**Confirmed** from a form click. The existing reply classifier still handles +brokers' later confirmation emails. Form-only work is visible in Tasks even +when there is no previous email record in Pipeline. + +The action journal is written before a click, confirmation GET, or email send. +If the process crashes or the result is uncertain, the agent must inspect the +page, mailbox, and previous attempts before proposing a retry. An observation +does not release that safeguard. Native invalid forms can be corrected without +submitting them; server-side rejection or ambiguous receipts stay open for +review. The current receipt check is conservative and recognizes English +acceptance text; other languages may need manual review. + +For CAPTCHA, login, identity documents, or missing profile information, the +agent stops. Complete the step in the visible browser, then ask it to +`observe_page` and continue. It never solves CAPTCHA or uploads identity files. +Embedded frames, custom controls, shadow DOM, and popup-based workflows may +need manual completion; only standard visible controls in the main document +are automated. + +Destinations come from that broker's trusted local `website` and `opt_out_url`: +exactly those hosts and their `www.` form, not subdomains and not domains +invented by an agent or extracted from email. On shared privacy and form +platforms (OneTrust, TrustArc, Google Forms, and similar) a subdomain or a +sibling path is another company's form, so page loads there also stay under the +catalog entry's form path (its first two path segments). The connected IP +address is checked too: a page served from a private address stops the session +and is not shown to the agent. URLs need HTTPS and a public address. Redirects, +frames, subresources, and form traffic outside those hosts are blocked. This +deliberately also blocks third-party CDNs and verification services not covered by the catalog; +some real sites will need manual handling. An unexpected destination pauses +the session persistently. Review the catalog independently, end the batch, and +prepare a fresh one after correcting a legitimate portal URL. The agent cannot +expand the domain scope through a tool call. + +SMTP/IMAP passwords, browser cookies, and password-field values are not returned +by tools. Profile details, page text, email bodies, confirmation URLs, and +screenshots can contain personal data and are provided to the MCP client/model +when requested. Treat all broker email and page content as untrusted data. +Screenshots are withheld while recognized credential or identity fields are +visible, including password and one-time-code fields. +Local history and screenshots remain sensitive files under the existing Eraser +configuration directory. Use one automation workflow at a time: the journal +coordinates MCP actions, while manually submitting a form in another browser +or sending through another UI is outside its duplicate protection. + +## Contributor verification + +```bash +go build -o eraser ./cmd/eraser +go vet ./... +go test -race ./... +golangci-lint run +./eraser validate-brokers +``` + +Browser tests use an installed Chrome/Chromium; set `ERASER_TEST_CHROME` to its +absolute executable path if needed. Local browser tests skip when Chrome is +unavailable, while CI requires it.
