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://learn.chatgpt.com/docs/extend/mcp). +Keep `begin_batch` and `retry_action` set to `approval_mode = "prompt"`. +Other tools can use `approve`: the server rejects form actions and sends until +a batch exists, and enforces that batch's scope afterward. + +These two approval settings are part of the authorization design. MCP itself +does not attest that a person clicked Approve. A client that automatically +approves every tool can start batches without a person reviewing them. Use +another client only if it can enforce the same approval policy. + +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. Leave Chrome +visible for manual verification; `--headless` is intended for fixture tests or +workflows that do not need intervention. Keep stdout reserved for MCP messages; +diagnostics go to stderr. + +## Try fictional data first + +Set the MCP arguments to `["mcp", "--demo"]`, or add a second server named +`eraser_demo` with those arguments and the same two tool approval overrides. +Restart that server to create a fresh demo. + +Ask Codex: + +> Use Eraser's demo.

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. Call `begin_batch` after you review that preview. Approval is valid only for + those tasks and email recipients in that profile and this MCP session. +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, obtain client approval, 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`, +including subdomains, not from domains invented by an agent or extracted from +email. 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. Tests exercise real MCP schema discovery, +profile isolation, batch scope and expiry, durable duplicate prevention, SMTP +limits/recovery, and the local forms with Chromium. No real mailbox or broker +is needed. Verify the demo's completed tasks, screenshots, and pending review +in the existing web UI before trying a small, explicitly approved real batch. diff --git a/examples/codex-mcp.toml b/examples/codex-mcp.toml new file mode 100644 index 0000000..00d768c --- /dev/null +++ b/examples/codex-mcp.toml @@ -0,0 +1,18 @@ +# Merge these tables into your Codex config; replace the absolute command path. +# Do not put email credentials in this file.

From e57e19b38e4de60e2990fe08d622550ae4dd9a56 Mon Sep 17 00:00:00 2001 From: Maris Popens Date: Sat, 17 Oct 2026 10:37:16 +0300 Subject: [PATCH 2/7] fix(mcp): require approval, scope platform hosts, keep pipeline forward-only - Batch previews are stored with a digest. Approval happens on the Automation page in the web UI or with eraser mcp approve, once and for 15 minutes. begin_batch spends that approval. - eraser mcp pending lists previews waiting for approval. - Brokers on shared privacy or form platforms may use only the exact tenant host in their catalog entry. Other brokers keep subdomain matching. - A response from a non-public address stops further actions on the page. - Automated pipeline updates only move a request forward. Web Confirm and Reject use an explicit override. - Document approval, platform hosts and the experimental status of eraser mcp. --- cmd/eraser/cmd_mcp.go | 48 ++++++++++ docs/mcp.md | 14 ++- docs/stability.md | 1 + internal/browser/automation.go | 79 ++++++++++++++++- internal/browser/automation_test.go | 26 ++++++ internal/history/approvals.go | 88 +++++++++++++++++++ internal/history/approvals_test.go | 47 ++++++++++ internal/history/history.go | 15 +--- internal/history/no_data_test.go | 2 +- internal/history/pipeline_rank.go | 57 ++++++++++++ internal/history/pipeline_rank_test.go | 25 ++++++ internal/mcpserver/batch.go | 35 ++++++-- internal/mcpserver/browser.go | 2 +- .../mcpserver/browser_integration_test.go | 1 + internal/mcpserver/server_test.go | 13 +++ internal/web/handlers_automation.go | 64 ++++++++++++++ internal/web/handlers_automation_test.go | 50 +++++++++++ internal/web/handlers_pages.go | 4 +- internal/web/server.go | 2 + internal/web/templates/automation.html | 58 ++++++++++++ 20 files changed, 599 insertions(+), 32 deletions(-) create mode 100644 internal/history/approvals.go create mode 100644 internal/history/approvals_test.go create mode 100644 internal/history/pipeline_rank.go create mode 100644 internal/history/pipeline_rank_test.go create mode 100644 internal/web/handlers_automation.go create mode 100644 internal/web/handlers_automation_test.go create mode 100644 internal/web/templates/automation.html diff --git a/cmd/eraser/cmd_mcp.go b/cmd/eraser/cmd_mcp.go index 046ba77..3a89862 100644 --- a/cmd/eraser/cmd_mcp.go +++ b/cmd/eraser/cmd_mcp.go @@ -6,7 +6,9 @@ import ( "os" "os/signal" "syscall" + "time" + "github.com/drumandbytes/eraser/internal/history" "github.com/drumandbytes/eraser/internal/mcpserver" "github.com/modelcontextprotocol/go-sdk/mcp" "github.com/spf13/cobra" @@ -44,8 +46,54 @@ func mcpCmd() *cobra.Command { return err }, } + cmd.AddCommand(mcpApproveCmd(), mcpPendingCmd()) cmd.Flags().BoolVar(&headless, "headless", false, "Hide Chrome (visible by default for verification handoff)") cmd.Flags().BoolVar(&demo, "demo", false, "Use isolated fake data and local sample forms; never access real email or brokers") cmd.Flags().StringVar(&chromePath, "chrome-path", "", "Optional path to Chrome/Chromium") return cmd } + +func mcpApproveCmd() *cobra.Command { + return &cobra.Command{ + Use: "approve ", Short: "Approve a previewed MCP batch (once, for 15 minutes)", + Args: cobra.ExactArgs(1), + RunE: func(cmd *cobra.Command, args []string) error { + store, err := openHistoryStore(history.DBPathFor(resolveConfigPath())) + if err != nil { + return err + } + defer func() { _ = store.Close() }() + if err := store.ApproveBatch(args[0], "cli"); err != nil { + return fmt.Errorf("approve %s: %w", args[0], err) + } + _, _ = fmt.Fprintf(cmd.OutOrStdout(), "Approved batch %s.

Key sections: - -- `profiles` - one entry per person: `id` (stable, stored in history - `default` for the one `eraser init` creates) + name/address/email + `additional_emails`/`name_variants`/`previous_addresses`/`additional_phones` for catching records indexed under old identities (editable in `eraser init` / `eraser profile edit` and on the web profile form, one per line). Each entry can set its own `mail.email`/`mail.inbox` to send/monitor through a dedicated account instead of the shared blocks below - see [multi-profile.md](../multi-profile/). A pre-0.11 top-level `profile:` block still loads and is rewritten as `profiles: [{id: default, ...}]` on the next save -- `email` - `from` + `smtp` (`host`, `port`, `username`, `password`). TLS is on by default: port 465 = implicit TLS, any other port = mandatory STARTTLS; `use_tls: false` is only accepted without a username (a local relay). Loopback hosts (Proton Mail Bridge) skip certificate verification. `provider:` is optional (only `smtp` is accepted). Setup presets live in `internal/config/providers.go` -- `options` - `template`, `rate_limit_ms`, `daily_send_limit`, `broker_list` (`full`/`verified`), `broker_file` (path to your own list), `regions`, `excluded_brokers`, `excluded_categories` (skip every broker in a category, e.g. `requires-id`), `send_mode` (`manual` = Eraser never sends; render with `draft` / `send --manual`, record with `mark-sent`; no `email:` block needed) -- `inbox` - IMAP settings (`provider` = a preset id that fills `server`/`port`, or set them directly; 993 = TLS, other ports = STARTTLS), for `monitor`/`pipeline`/the web UI's inbox scan. Shared by default across every profile that doesn't set its own `mail.inbox` override (see [multi-profile.md](../multi-profile/#shared-inbox)); `monitor` scans every distinct inbox in one run, the web UI's scan/rescan only the active profile's own -- `pipeline` - browser automation settings for `fill` -- `schedule` - `enabled: true` makes a running `eraser serve` run an automated cycle every 6 hours (the in-app fallback when the OS job from `schedule install` isn't set up; ignored while it is).
