DenialPath is a remote MCP server that gives an AI agent 6 tools, among them check_claim, draft_appeal, explain_denial. It answers at https://denialpath.vercel.app/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Deterministic CMS NCCI/MUE claim scrubbing and CARC/RARC denial explanations, cited to source.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_claim | Scrub a claim against the NCCI procedure-to-procedure (PTP) edits and medically unlikely edits (MUE) in force on its date of service. Deterministic: no model, so identical input always returns an identical verdict. Every finding.status is o Inputs: dateOfService, payerSlug, lines |
draft_appeal | Generate an appeal letter for a denial, assembled deterministically from cited facts. REQUIRES A PRO OR SCALE PLAN. Called by an anonymous caller or a key on the free plan, this returns an upgrade_required error naming the pricing page - it Inputs: carc, rarc, payerSlug, providerName, claimNumber, dateOfService |
explain_denial | Explain a CARC (Claim Adjustment Reason Code) and any RARCs (Remittance Advice Remark Codes) from a remittance: plain meaning, ranked corrective actions, and whether an appeal is worth filing. found:false means we do not hold that CARC in o Inputs: carc, rarc, payer |
get_mue | Look up the medically unlikely edit (MUE) unit limit for a single CPT/HCPCS code. status is found or no_data; no_data means we hold no MUE value for this code in our dataset, not that CMS publishes none. When found, the returned limit.mai ( Inputs: code |
get_ncci_edits | Look up NCCI procedure-to-procedure (PTP) edits, in two modes. Pair mode: pass column1, column2 (either order) and dateOfService to check whether that specific pair bundles on that date; status is no_data (we hold no edit for this pair in o Inputs: column1, column2, dateOfService, code |
get_timely_filing | Days remaining to file an initial claim (or, if already past, how far over) for a payer given a date of service. daysRemaining and expired are null when we hold no published timely filing limit for that payer, which is common since many lim Inputs: payer, dateOfService |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://denialpath.vercel.app/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
