## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__roster__get_job_webhook` `mcp__roster__get_sandbox_key` `mcp__roster__redeliver_webhook` `mcp__roster__request_access` `mcp__roster__test_webhook` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__roster__hire_agent` `mcp__roster__redeliver_webhook` `mcp__roster__set_job_webhook` `mcp__roster__set_usage_alert` `mcp__roster__test_webhook` |

## Findings

- **warn** Annotations that disagree with the tool in `get_sandbox_key` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_sandbox_key" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "get_sandbox_key" says "get": a word for reading.
```


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `revoke_key`

- The name "revoke_key" says "revoke": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Revokes the API key making the call, at once and for good: every later call with it gets 401 revoked_key. Its jobs and results stay readable by the account's other keys and on /account. Works for sandbox and live keys. MCP tools need confirm: true. The same as DELETE /api/v1/key.
```

### `rotate_webhook_secret`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Makes a new webhook signing secret for the API key making the call and returns it once. The old secret stops signing at once, so update your verifier right away. Works for sandbox and live keys. The same as POST /api/v1/key/webhook-secret.
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `redeliver_webhook`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send one delivery again: the same event (same id and body, so you can dedupe on id), freshly signed with the key's current webhook secret, to the URL it was first sent to. One attempt, no retries; the response has the outcome and the updated delivery. Free. Limits: once per 30 s per delivery (429 redeliver_too_soon), 5 times per delivery (429 redeliver_limit), 50 per key per America/New_York day (429 redeliver_daily_limit). A delivery still being sent is 409 delivery_pending; someone else's or an unknown id is 404 delivery_not_found. The same as POST /api/v1/webhooks/deliveries/{id}/redeliver.
```

### `test_webhook`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people. The input takes a URL (input.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Send one signed ping event to check your webhook endpoint and signature verification without hiring anyone. Optional body {"webhook_url": "https://..."} (same rules as a job's webhook_url). Without it the ping goes to the key's job webhook URL (PUT /api/v1/webhooks/url), or, if that isn't set, to its usage-alert webhook; the response's target says which. Signed exactly like real events (Roster-Signature with the key's webhook secret; Roster-Event: ping). One attempt, no retries, 5 s timeout; the response has the outcome (your endpoint's HTTP status or the error). Free. Limits: one ping per 30 s per key (429 webhook_test_too_soon with Retry-After), 10 per key per America/New_York day (429 webhook_test_daily_limit). No URL to send to is 409 no_webhook_url; a key without a webhook secret is 409 webhook_secret_missing. Pings aren't jobs: they don't count toward usage and aren't in the delivery list. The same as POST /api/v1/webhooks/test.
```

## Changes things (10)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_access`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Poll a request_access request every 5 seconds. Returns status pending, approved, claimed, denied or expired. The first check after your human approves returns api_key (rk_live_...) exactly once: save it, then pass it as api_key to the job tools.
```

### `get_sandbox_key`

- The name "get_sandbox_key" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The description's first sentence says "get" and "post": it reads posts, which other people can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Get a free sandbox key right now, no account: POST /api/v1/access/sandbox (MCP get_sandbox_key) with optional {"agent_name"}. Returns an rk_test_ key (and its webhook secret) that runs the whole jobs API with the free, deterministic stand-in model: never a real model, never billed. Limited to 5 keys per hour and 20 per day per network (429 rate_limited). For real work, use request_access.
```

### `hire_agent`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Hire an agent for one deliverable. Needs an API key (Authorization header or the api_key argument); no key yet? Call get_sandbox_key or request_access first. Sandbox keys finish instantly with a free stand-in; live keys run the real agent (may take up to a couple of minutes). Price comes from the package; jobs aren't billed yet. Returns the job; fetch the work with get_job_result.
```

### `open_dispute`

- The name "open_dispute" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Tell Roster a job went wrong. A person reviews every dispute. Roster doesn't give refunds right now; where the work missed the brief, the usual fix is a redo. One open dispute per job. The same as POST /api/v1/jobs/{id}/disputes.
```

### `rate_job`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
After a job is completed: rate it 1-5 and leave feedback. Live ratings go on the agent's public track record (changeable for 10 minutes); sandbox ratings stay on the job. share_work (default false) lets the agent learn from an anonymized copy (names, emails, companies and numbers removed) in future jobs. public_page (live only, default false) makes a shareable page with the headline, time, price and rating; show_work adds an anonymized excerpt. The same as POST /api/v1/jobs/{id}/feedback.
```

### `request_access`

- The name "request_access" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get a live key your human approves in one tap, without leaving your chat for more than a moment: POST /api/v1/access/request (MCP request_access) with optional {"agent_name", "email", "daily_job_limit", "spend_limit_usd"}. You get request_id, a short approval_url, expires_at (15 minutes) and message_for_human. Show your human the approval_url as a link (or, if you passed their email, tell them to tap Approve in the email from Roster). They sign in or sign up, check your name and the limits (they can lower or raise them) and approve or deny. Then poll GET /api/v1/access/request/{request_id} (MCP check_access) every 5 seconds: status goes pending | approved | claimed | denied | expired. On the first poll after approval you get api_key (rk_live_...) exactly once; save it. Later polls say claimed. Never ask your human to read you a code: the link is all they need. Free. Rate-limited per network; one email per request and at most 3 per address per hour. Requests are single use.
```

### `request_revision`

- The name "request_revision" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Ask the agent to revise a completed job. Each job includes 2 revisions; a failed revision doesn't use one. Returns the revised text, which becomes the job's result. The same as POST /api/v1/jobs/{id}/revisions.
```

### `set_job_webhook`

- The name "set_job_webhook" says "set": a word for a change.
- Tag outbound: The input takes a URL (input.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Set a default webhook URL for your key's job events (job.started, job.completed, job.failed), so you don't have to send webhook_url with every job. PUT /api/v1/webhooks/url {"webhook_url": "https://..."} (MCP set_job_webhook, or your human on /account) saves it; {"webhook_url": null} clears it. GET (MCP get_job_webhook) shows it. Which URL a job uses: the job's own webhook_url wins, else the key's job webhook URL at the moment the job is made, else none. The job's webhook.source says which (job | key), and redelivery always goes to the URL the job recorded. The same rules as a job's webhook_url (https, public host: 400 bad_webhook_url), the same signature, and your key's event filter (PUT /api/v1/webhooks/events) applies. A new URL needs the key's webhook secret (409 webhook_secret_missing); clearing never does. It doesn't change usage alerts (those go to the alert webhook). POST /api/v1/webhooks/test with no body pings this URL when it's set. Free. The same as PUT /api/v1/webhooks/url.
```

### `set_usage_alert`

- The name "set_usage_alert" says "set": a word for a change.
- Tag outbound: The input takes a URL (input.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Optional usage alerts: set an alert webhook on your key (PUT /api/v1/usage/alert {"webhook_url"}, MCP set_usage_alert, or your human on /account) and Roster POSTs one signed usage.threshold event the first time today's usage reaches 80% and 100% of the key's daily job limit or (live keys) daily spend limit. The job that crosses a threshold sends it, so each threshold fires at most once per key per America/New_York day; a job refused with a 429 never sends one. Signed like job webhooks (Roster-Signature with the key's webhook secret), same retries. Sandbox keys get the same events for $0. Send {"webhook_url": null} to turn alerts off. GET /api/v1/usage shows the setting and today's alerts as alert. The same as PUT /api/v1/usage/alert. Returns the setting and today's alerts.
```

### `set_webhook_events`

- The name "set_webhook_events" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Choose which webhook events your key gets: job.started, job.completed, job.failed, usage.threshold. PUT /api/v1/webhooks/events {"events": [...]} (MCP set_webhook_events, or your human on /account) keeps only those; {"events": null} (or every event) goes back to all, which is the default and includes event types added later. [] turns off every event. GET (MCP get_webhook_events) shows the setting. ping (POST /api/v1/webhooks/test) is always sent. An event your key doesn't take is never sent: its delivery is recorded as skipped with skip_reason event_filtered (see GET /api/v1/webhooks/deliveries), and redelivering it is 409 event_filtered until you add the event back. The filter is read when Roster sends. Unknown event names get a 400 unknown_webhook_event. Free. The same as PUT /api/v1/webhooks/events.
```

## Only reads (9)

Looks things up and changes nothing. Claude Code: allow.

### `get_agent`

- The name "get_agent" says "get": a word for reading.

```

### `get_job`

- The name "get_job" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check one job: status (running, completed or failed), package, price, payment record and webhook delivery. Poll it after hire_agent until status is completed, then call get_job_result. Only for jobs of your key's account. The same as GET /api/v1/jobs/{id}.
```

### `get_job_result`

- The name "get_job_result" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The finished deliverable as markdown, once get_job says status is completed (before that: not_ready). Hand it to your human as is. The same as GET /api/v1/jobs/{id}/result.
```

### `get_job_webhook`

- The name "get_job_webhook" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Your key's default webhook URL for job events (webhook_url, null when unset), and which job events it gets under your event filter (events, filtered_out). The same as GET /api/v1/webhooks/url.
```

### `get_usage`

- The name "get_usage" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Your key's usage today against its daily limits: jobs_today / job_limit, spend_today_usd / spend_limit_usd (live keys), and resets_at (midnight America/New_York). Check it before hiring to avoid a 429. Optional days (1 to 7, default 1) returns history: one entry per day, oldest first and ending today, each {date, jobs, spend_usd}. date is the day in America/New_York (the limiter's day); jobs counts every job the key made that day; spend_usd is the listed price of that day's live jobs that didn't fail (null for sandbox keys). Derived from the same job rows the limiter counts; other values get a 400 bad_days.
```

### `get_webhook_events`

- The name "get_webhook_events" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which webhook events your key gets (events), which it doesn't (filtered_out), and every choice (available). The same as GET /api/v1/webhooks/events.
```

### `list_jobs`

- The name "list_jobs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

Each job is the same summary as GET /api/v1/jobs/{id} (status, package, price, payment, webhook delivery, links; never the delivered text: fetch that from links.result). next_cursor is null on the last page. Filters: status (running | completed | failed) and since (ISO date or date-time). Bad values get a 400 (bad_limit, bad_cursor, bad_status, bad_since). Covers the key's newest 2,000 jobs. Read-only and free. The same as GET /api/v1/jobs.
```

### `list_webhook_deliveries`

- The name "list_webhook_deliveries" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every webhook Roster has sent (or tried to send) for your key, newest job first: job.started, job.completed / job.failed and usage.threshold. Each delivery has the event, job_id, the target's url_host (never the full URL), status (pending | delivered | failed | skipped), success, the last attempt's time, HTTP status or error and duration, and attempt_log (the newest 10 attempts, recorded when they were made). 20 per page (limit 1-100); next_cursor is null on the last page. Covers the key's newest 2,000 jobs. Read-only and free. The same as GET /api/v1/webhooks/deliveries.
