# AI Connectors Directory — 3,150 ChatGPT Apps and Claude Connectors An independent catalogue of 3,150 AI connectors across the ChatGPT and Claude marketplace directories as of August 2026: where each is listed, what it exposes, and what its live endpoint actually returns. Source: https://node8.ai/ai-connectors/ --- AI Connectors Directory # Every AI connector, across marketplaces, by what it exposes We catalogued the ChatGPT apps directory and the Claude connectors directory in August 2026, 2,305 listings on one side and 1,253 on the other, and merged them into one catalogue of 3,150 products. Each profile shows where the product is listed and what each marketplace listing declares, with live-endpoint measurements where the server answered.

Since one MCP server can serve both surfaces, the other 2,758 are a distribution decision away from doubling their reach. ### [Suger](https://node8.ai/ai-connectors/sales-marketing/suger/) Cloud marketplace and go-to-market data in chat ChatGPT · Claude · 137 tools ### [Teamwork.com](https://node8.ai/ai-connectors/productivity/teamwork-com/) Sync Teamwork projects and tasks into Codex ChatGPT · Claude · 100 tools ### [Deel](https://node8.ai/ai-connectors/finance/deel/) Global hiring cost comparisons and take-home pay estimates ChatGPT · Claude · 95 tools ### [Ninjo](https://node8.ai/ai-connectors/sales-marketing/ninjo/) Configure AI engagement agents and WhatsApp templates ChatGPT · Claude · 95 tools ### [Civic Marketplace](https://node8.ai/ai-connectors/productivity/civic-marketplace/) Cooperative contract and supplier search for public agencies ChatGPT · Claude · 89 tools ### [DataCamp](https://node8.ai/ai-connectors/education/datacamp/) Course recommendations for data and AI skills ChatGPT · Claude · 87 tools ### [Soundcharts](https://node8.ai/ai-connectors/entertainment/soundcharts/) Music industry data and reporting ChatGPT · Claude · 86 tools ### [Resend](https://node8.ai/ai-connectors/communication/resend/) Send and inspect transactional email from ChatGPT ChatGPT · Claude · 85 tools ### [Zentrik](https://node8.ai/ai-connectors/productivity/zentrik/) Customer evidence search for product decisions ChatGPT · Claude · 80 tools ### [Endlss](https://node8.ai/ai-connectors/sales-marketing/endlss/) Ambassador and creator program management in chat ChatGPT · Claude · 78 tools ### [Conversion](https://node8.ai/ai-connectors/sales-marketing/conversion/) Marketing platform data and campaign creation from chat ChatGPT · Claude · 77 tools ### [ChartMogul](https://node8.ai/ai-connectors/data-analytics/chartmogul/) Subscription revenue analytics queried in plain language ChatGPT · Claude · 76 tools [The ChatGPT side, in full](https://node8.ai/ai-connectors/chatgpt/) [The Claude side, in full](https://node8.ai/ai-connectors/claude/) Browse ## Categories Each hub lists every connector filed under it across both marketplaces, with the bucket's marketplace split and median tool depth. 760 connectors · 468 on ChatGPT · 462 on Claude ### [AI connectors for Productivity](https://node8.ai/ai-connectors/productivity/) The default bucket on both marketplaces.

[Browse Nonprofit](https://node8.ai/ai-connectors/nonprofit/) Categories come from the marketplace listings themselves, mapped onto one shared set, and at row level they are noisy: connectors are filed by their publisher, and plenty sit under a heading that does not describe the product well. Treat the grouping as a way to navigate the directory, not as a market segmentation. Notable ## The 9 connectors Anthropic built itself Everything else in the Claude directory is published by a third party, either as a verified partner or community-listed. The ChatGPT directory's equivalent: 34 of its apps are OpenAI-built. ### [Anthropic Economic Index](https://node8.ai/ai-connectors/data-analytics/anthropic-economic-index/) Public data on how Claude usage varies by country and occupation 9 tools · Data & Analytics ### [ICD-10 Codes](https://node8.ai/ai-connectors/healthcare/icd-10-codes/) ICD-10-CM and ICD-10-PCS lookup, search and validation 9 tools · Healthcare & Life Sciences ### [bioRxiv](https://node8.ai/ai-connectors/healthcare/biorxiv/) Preprint search across bioRxiv and medRxiv 8 tools · Healthcare & Life Sciences ### [CMS Coverage](https://node8.ai/ai-connectors/healthcare/cms-coverage/) Medicare Part B coverage determinations from the CMS database 8 tools · Healthcare & Life Sciences ### [Microsoft 365](https://node8.ai/ai-connectors/productivity/microsoft-365/) Work SharePoint, OneDrive, Outlook, and Teams data inside Claude 7 tools · Productivity ### [PubMed](https://node8.ai/ai-connectors/healthcare/pubmed/) Search PubMed citations and retrieve PubMed Central full text 7 tools · Healthcare & Life Sciences ### [ChEMBL](https://node8.ai/ai-connectors/healthcare/chembl/) Bioactivity, targets and mechanism data from the ChEMBL database 6 tools · Healthcare & Life Sciences ### [Clinical Trials](https://node8.ai/ai-connectors/healthcare/clinical-trials/) Search ClinicalTrials.gov by condition, sponsor, investigator or eligibility 6 tools · Healthcare & Life Sciences ### [NPI Registry](https://node8.ai/ai-connectors/healthcare/npi-registry/) Look up and validate US healthcare provider NPI numbers 3 tools · Healthcare & Life Sciences Who publishes ## Almost nobody has built a second one ### 97.7% of Claude publishers list exactly one And 95.6% of ChatGPT developers do too. Both catalogues are nearly all tail: a company with a well-built second or third connector is still an unusual thing. ### 392 products are on both marketplaces Out of 3,150. The overlap is where the strongest publishers cluster: the companies that treated distribution as part of the build, not an afterthought. ### 98.7% of ChatGPT listings publish both policies Privacy policy and terms of service are effectively table stakes in the ChatGPT review process, and 99.7% of listings authenticate at install. ### 96.2% of Claude listings publish an endpoint The rest publish documentation but no endpoint URL in the directory record. They are real listings; the URL has to come from the publisher's own setup docs. Method ## How this catalogue was built Both marketplace directories were walked in August 2026: 2,305 ChatGPT listings and 1,253 Claude listings, nothing dropped. Products listed in both were merged into one profile when the publisher domain and product name match; where the domains disagree but the product is plainly the same, the profile says the match is by name. Where a Claude listing publishes an endpoint URL, Node8 called it directly, an MCP initialize followed by tools/list and nothing more, and recorded what came back: a tool list, a credential gate, or a CDN block. Everything comparative on these pages (percentiles, category ranks, tier rarity, marketplace overlap) is computed by Node8 from the snapshot. Publisher descriptions are quoted and attributed, never presented as ours. The full inventory of tools the live servers returned is at [verified MCP tools](https://node8.ai/ai-connectors/tools/), and the analysis of what the measurements show is in [The State of Claude Connectors](https://node8.ai/state-of-claude-connectors). Counts are accurate as of August 2026 and will drift as the directories change. Listing a company here is not an endorsement, and Node8 has no commercial relationship with these companies unless separately stated. FAQ ## Directory questions, answered What is an AI connector? An AI connector is an MCP server a company publishes so an assistant (ChatGPT, Claude, Microsoft Copilot) can reach that company’s data or take actions against it in conversation. The server declares a set of tools; the assistant calls them. ChatGPT apps and Claude connectors are the same idea distributed through two different marketplaces, and one server can back both. Where does this directory’s data come from? Both marketplace directories were captured in August 2026: 2,305 listings in the ChatGPT apps directory and 1,253 in the Claude connectors directory. Products listed in both are merged into one page, matched by publisher domain and product name; 392 of the 3,150 products here are on both marketplaces. The comparisons on these pages are computed by Node8. What does the tool count actually mean? It is the number of MCP tools a connector declares in its Claude listing (the ChatGPT directory does not publish counts). The Claude-directory median is 11; the mean is 19.7, pulled up by a long tail that reaches 255. Node8 also called every published endpoint directly: 222 answered, and 31% of those publish a count that does not match their server. How much overlap is there between the two marketplaces? 392 of the 3,150 products in this directory are listed in both the ChatGPT and Claude directories, matched by publisher domain and product name. The other 2,758 are on exactly one marketplace, which is a distribution decision rather than a technical one: the same MCP server can serve both. What do the Claude verification tiers mean? Community-listed means self-published; partner verification is a review step; and 9 connectors were built by Anthropic itself. The tier says who published and whether it was reviewed, not whether the connector is good. The ChatGPT directory has no equivalent tier, but 99.7% of its listings authenticate at install. Are the categories reliable? Categories come from the marketplace listings themselves, mapped onto one shared set, and at row level they are noisy: connectors are filed by their publisher, and plenty sit under a heading that does not describe the product well. Treat the grouping as a way to navigate the directory, not as a market segmentation. Is Node8 affiliated with these connectors? No. This is an independent catalogue of publicly listed connectors and apps, published as reference. Node8 builds MCP servers for its own clients and has no commercial relationship with the companies listed here unless separately stated. ## One server. ChatGPT, Claude, and Copilot. Node8 designs the tool surface, builds and secures the MCP server, and takes it through review on every marketplace that matters. Most first connectors ship in eight to twelve weeks.
