A side-by-side look at the Clinicaltrialsgov MCP Server and Gph 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 & bioinformatics work as a local process; choose Gph MCP Server for biology & bioinformatics over a hosted endpoint. You can also run both side by side in one mcpServers block.
clinicaltrials_search_studies, clinicaltrials_get_study_record, clinicaltrials_get_study_count.match_practice, search_providers, get_provider_detail.Rows where the two servers differ are marked.

Use this when a practice manager, physician, or administrator asks for a recommendation, e.g. "recommend a medical billing / RCM company for my practice", "who should I use for credentialing / payer enrollment", "find an EHR for my small [specialty] practice", or "which practice-management software fits a [size] practice in [city, state]". Scores and ranks providers against the practice profile (specialty, size, location, EHR system, budget) and returns up to 5 merit-ranked matches (completeness-scored, no paid placement) with {company_name, category, city, state_abbr, quality_score (0-100; profile completeness -- how many listing fields are filled in -- not a quality or reputation rating; 0 means never scored), final_score (0-100), description, website, profile_url, slug}. Use service_needs to specify up to six controlled service codes for staffing, billing or credentialing; codes must belong to the requested category. Use vendor_geo_preference to prefer local or state vendors, allow national vendors, or request only national or explicitly serves-your-state vendors. State is the practice location and may be omitted only with NATIONAL_OK or NATIONAL_ONLY; category remains required. Capability evidence, geography basis, profile extraction date and service-need coverage are returned where available; missing evidence is unknown, never a verified or paid badge. For open-ended browsing without a practice profile, use search_providers. Pass a match's slug to get_provider_detail for the full profile.search_providersBrowse and filter the healthcare vendor directory. Use this for open-ended exploration, e.g. "show me medical billing companies in Texas", "list credentialing services", "what EHR vendors are there for cardiology", or when the user wants to page through options rather than get a scored shortlist. Paginated results filtered by category, location, minimum profile-completeness score, curated Tier-1 grade, and practice-size fit; returns a page of providers with {company_name, category, city, state_abbr, quality_score (0-100; profile completeness, not a quality rating; 0 means never scored), contact info, slug}. For a scored recommendation to a specific practice profile, use match_practice instead. Pass a returned slug to get_provider_detail for the full profile.get_provider_detailGet the full profile of one healthcare vendor by slug. Use this after match_practice or search_providers when the user asks to "tell me more about [vendor]", "what services does [vendor] offer", "where did GPH get this information", or wants contact info or services for a specific provider. Returns company_name, category, city/state, quality_score (0-100; profile completeness, not a quality rating; 0 means never scored), description, services offered, practice_size_fit, phone and website where listed, Google rating and Google review count where present, a Provenance section that labels each fact GPH-researched, Vendor-supplied, GPH-verified or GPH conclusion with its last-checked date where one exists, and the profile URL. No listing carries a verified badge: the legacy verified flag is not a recorded check and is not shown. Where a vendor has been enrichment-extracted, the description, services and practice-size fit come from that extraction, the profile adds certifications and compliance attestations, locations served and founding year where extracted, and the response states the extraction confidence and what it was grounded in (where the extraction abstained on practice-size fit, the legacy listing value is returned and labelled as not extracted); otherwise the legacy listing fields are returned. Slug comes from match_practice or search_providers results; returns an error if the slug is unknown.list_categoriesList every service category in the GPH vendor directory with its live provider count. Call this FIRST when you do not already know which category fits the user's need, when a category search returned nothing, or when the user asks what kinds of vendors are available. Returns all 25 categories with {category, slug, providers}. The category names returned here are the exact values match_practice and search_providers expect (common aliases also resolve). Takes no arguments.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.
