Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum fourteen caller-assigned Miller 1992 CIRS-G organ-system integers (each 0-4) and return the published total (max 56), the count of categories endorsed (rating ≥1), and the count of categories rated ≥3.

When to use

When an agent already has Miller 1992 0-4 integers for the fourteen CIRS-G organ systems and needs the published total and ≥3 category count. magent does not examine the patient, diagnose comorbidity, score Charlson, or apply G8.

When not to use

  • Not a medical device and not a diagnosis or treatment order.
  • Each of the fourteen organ-system ratings is a caller-assigned integer 0-4 (0 no problem, 1 current mild or past significant, 2 moderate disability or first-line therapy, 3 severe or uncontrollable chronic, 4 extremely severe, immediate treatment, or end-organ failure). magent does not examine the patient.
  • This is Miller 1992 CIRS-G only (fourteen organ systems including psychiatric illness; max 56). It is not Charlson, not Linn 1968 CIRS, and not G8.
  • Miller 1992 / the CIRS-G scoring sheet published total score, number of categories endorsed, and counts of categories at severity 3 and 4. This tool returns score, categories_endorsed, and categories_ge_3 (ratings 3 or 4). It does not invent a total-score class or a severity-index cutoff.

Formula

CIRS-G = heart + vascular + hematopoietic + respiratory + eent + upper_gi + lower_gi + liver + renal + genitourinary + musculoskeletal + neurologic + endocrine_metabolic + psychiatric; each caller-assigned 0-4; max 56; Miller 1992; categories_endorsed is count of ratings ≥1; categories_ge_3 is count of ratings ≥3; no total-score class

Worked example

All organ systems 0

Given: eent=0endocrine_metabolic=0genitourinary=0heart=0hematopoietic=0liver=0lower_gi=0musculoskeletal=0neurologic=0psychiatric=0renal=0respiratory=0upper_gi=0vascular=0

  1. heart, vascular, hematopoietic, respiratory, eent, upper_gi, lower_gi, liver, renal, genitourinary, musculoskeletal, neurologic, endocrine_metabolic, and psychiatric are 0 as assigned by the caller
  2. Score = 0 (max 56); categories_endorsed = 0; categories_ge_3 = 0. Miller 1992 published no total-score class.

Heart 3 and vascular 4

Given: eent=0endocrine_metabolic=0genitourinary=0heart=3hematopoietic=0liver=0lower_gi=0musculoskeletal=0neurologic=0psychiatric=0renal=0respiratory=0upper_gi=0vascular=4

  1. heart 3 + vascular 4; remaining twelve systems 0
  2. Score = 7; categories_endorsed = 2; categories_ge_3 = 2 (both ratings ≥3). No total-score class.

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.

POST /api/calc/cirs_g Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 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.
