A side-by-side look at the Clinicaltrialsgov MCP Server and Mymedi AI MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Clinicaltrialsgov MCP Server for biology, medicine and bioinformatics work as a local process; choose Mymedi AI MCP Server for biology, medicine and bioinformatics as a local process. You can also run both side by side in one block.

Returns paRequired flag, category, nationwide-since date, and list version. Original Medicare FFS scope. Free, no API key required.denial_code_infoExplain a DME claim denial code (CARC). Returns title, meaning, common DME causes, fixes, appealability, and related codes. Free, no API key required.code_lookup_basicLook up basic metadata for a medical code: code, codeType, description, category, isActive. Basic metadata only — the paid code_lookup adds full metadata. Free, no API key required.reimbursement_basicLook up Medicare payment for a code. Returns the national PFS facility and non-facility payment (CMS RVU × conversion factor) for professional services, plus DMEPOS fee-schedule ranges (rental/purchase, min–max across state fees) for DME items like E/K/L codes. Free, no API key required.order_readiness_checklistBlank pre-delivery checklist for a HCPCS DMEPOS code: the universal standard written order (SWO) elements (42 CFR 410.38(d)), whether the code requires a face-to-face encounter and written order prior to delivery (F2F/WOPD), and whether it is on the Medicare Required Prior Authorization List. Requirement definitions only — PHI-free, never send patient data. Free, no API key required.modifier_advisorEditorial guidance on DMEPOS billing modifiers: the KX/GA/GY/GZ medical-necessity and liability family, RR/NU/UE rental-vs-purchase, capped-rental month markers (KH/KI/KJ), and RT/LT laterality. Pass a HCPCS code to scope guidance to that item's DMEPOS category, or a category directly; add a scenario phrase (e.g., "ABN on file", "bilateral") to surface the relevant modifiers. Original editorial content, not payer policy. PHI-free. Free, no API key required.code_lookupLook up a medical code (ICD-10, CPT, HCPCS). Returns description, category, active status, and related codes. For DMEPOS (HCPCS) codes it also returns a labeled fee schedule: per-modifier (RR/NU/UE) national min–max ranges, or — when a state is given — that state's exact non-rural and rural rates. Source: CMS DMEPOS Fee Schedule (DME26-B).code_lookup_batchLook up a list of medical codes (ICD-10, CPT, HCPCS) in one call. Per-item results mirror code_lookup (description, category, active status, related codes, DMEPOS fee schedule with optional state filter). Priced per code — $0.001 × number of codes, max 25 per call; the full charge is refunded automatically when every code misses.code_suggestSuggest ICD-10/CPT/HCPCS codes from a clinical description. Term-based search over the 90K-code CMS database, ranked by matched-term coverage and relevance. Works with natural sentences ("patient with obstructive sleep apnea prescribed CPAP"). Automatically refunds the call when nothing matches.code_validateValidate a medical code for correctness, active status, and context. Returns warnings and errors.code_validate_batchValidate a list of medical codes for correctness, active status, and optional date-of-service context in one call. Per-item results mirror code_validate (valid, active, warnings, errors, codeDetails). Priced per code — $0.005 × number of codes, max 25 per call. An invalid code is a billable answer (valid:false), same as the single validate.pa_predictPrior-authorization outlook for a procedure code. When a historical cohort of decided PAs exists (≥10), returns a data-driven approval rate with cohort size and confidence. When no cohort exists, returns the verifiable facts instead — CMS Required Prior Authorization List status, category, and published review timeframes — and explicitly reports that no probability was computed (the call is refunded on this path). Never fabricates a probability. Original Medicare FFS scope.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
