Not a medical device. Not a diagnosis, dose, or listing recommendation.
What it computes
Apply the Rao 2016 Rome IV fecal incontinence (F1) diagnostic criteria and return whether the published fecal incontinence box holds (rome_iv_fecal_incontinence).
When to use
When an agent already has the four caller-assigned Rao 2016 Rome IV fecal incontinence flags and needs whether the published fecal incontinence box holds. magent does not examine the patient or read manometry.
When not to use
- Not a medical device.
- Not a diagnosis. magent does not diagnose fecal incontinence.
- The caller assigns the four flags. magent does not examine the patient or read manometry.
- This tool is Rao 2016 Rome IV fecal incontinence (F1) only. The research 2–4 episodes in 4 weeks frequency remark is copy-only and is not parsed. Not pediatric nonretentive fecal incontinence (H3b). Not Wexner constipation score.
Formula
rome_iv_fecal_incontinence iff recurrent_uncontrolled_passage_of_fecal_material and developmental_age_at_least_4 and fulfilled_last_3_months and onset_at_least_6_months (Rao 2016 Rome IV fecal incontinence)

- Developmental age at least 4 years is true
- Criteria fulfilled for the last 3 months and onset at least 6 months prior are true
- rome_iv_fecal_incontinence is true
Three required flags without 6-month onset
Given:
developmental_age_at_least_4=truefulfilled_last_3_months=trueonset_at_least_6_months=falserecurrent_uncontrolled_passage_of_fecal_material=true
- Three required flags hold

Parameters
| Name | Type | Required | Description |
|---|---|---|---|
recurrent_uncontrolled_passage_of_fecal_material |
boolean | required | Recurrent uncontrolled passage of fecal material for at least 3 months in a person with developmental age at least 4 years (Rao 2016 Rome IV fecal incontinence F1 clinical definition). true or false as assigned by the caller. magent does not examine the patient. |
developmental_age_at_least_4 |
boolean | required | Developmental age at least 4 years, as assigned (Rao 2016). true or false as assigned by the caller. magent does not examine the patient. |
fulfilled_last_3_months |
boolean | required | Criteria fulfilled for the last 3 months, as assigned (Rao 2016). true or false as assigned by the caller. magent does not take a history. |
onset_at_least_6_months |
boolean | required | Symptom onset at least 6 months prior to diagnosis, as assigned (Rao 2016 research timing, same as other magent Rome tools). true or false as assigned by the caller. magent does not take a history. |
Bulk (POST)
POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.
- 1 to 25 items. Each item uses the same keys as the GET query parameters.
- POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
- The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
- HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
- Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
- x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Payment
Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64
PAYMENT-REQUIRED
header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake
and shared payment errors: Payments.
Stdio MCP: /docs/mcp.
Guarantees
- HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
- exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
- HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
- Execution is timeout-bounded and concurrency-capped.
- Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
