# Nexus — AI Connector Nexus publishes 5 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/healthcare/nexus/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Healthcare & Life Sciences](https://node8.ai/ai-connectors/healthcare/) # Nexus Workout, meal and body weight logging inside the chat Listed in Claude · 5 published tools · Community-listed [Claude connector docs](https://nexus.kushalsm.com/usage-guide/) [nexus.kushalsm.com](https://nexus.kushalsm.com/) Overview ## What Nexus does Nexus keeps a training and nutrition log where the entry point is a sentence rather than a form. A lift or a meal described in passing gets recorded, with calorie and macro estimates filled in by the model and stored by Nexus, and corrections applied by saying what was wrong. Queries run against that accumulated history: what was eaten on a given day, how a lift has progressed, whether a protein target was met over a week. Each day condenses to one card showing calories against goal, macros and workouts with personal records flagged. A small social layer lets friends added by code see each other's daily cards. Five tools are declared. ### Who it is for People tracking lifting and nutrition who would rather type a sentence than fill a form. ### Tool surface The five declared tools sit behind a sign-in requirement, which follows from a log that belongs to one person, and their split between writing entries and reading history is not visible here. Availability ## Where Nexus is listed Nexus is listed in the Claude connectors directory only. Kushal has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Nexus publishes 5 tools to Claude, a deliberately narrow surface; only 22.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Healthcare & Life Sciences publishes 6, so this one sits one tool below its bucket's median, 30th of 51. It falls in the 4-6 tools band, which holds 16.2% of the Claude directory. Nexus publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Kushal Verification Community-listed (61.5% of the Claude directory) Filed under Health & Life Sciences Endpoint `https://claude-mcp.nexus.kushalsm.com/mcp` Documentation [Publisher setup docs](https://nexus.kushalsm.com/usage-guide/) Published tools 5 · 4-6 tools band Depth rank in Healthcare & Life Sciences 30 of 51 Snapshot August 2026 Nexus is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Kushal describes it > Nexus is a workout, meal, and body-weight log that lives inside the chat. Say 'bench 4x8 at 80kg' or 'two eggs and toast' and it's logged — Claude estimates the calories and macros, Nexus keeps the record. Ask what you ate yesterday, how your bench is progressing, or whether you hit protein this week, and the answer comes from your actual history. Every day gets one card: calories against your goal, macros, and workouts with PRs flagged. Correct anything by saying so ('that was 90kg, not 80'). Set daily calorie and protein targets once and every day is measured against them. There's also a small social layer: add friends with a code and see each other's daily cards for accountability.
