Runs locally with no API key: looks up drug labels and adverse events from FDA, EMA and DailyMed, plus WHO health statistics, PubMed papers, clinical trials and clinical guidelines, with auto-generated evidence-level tags on papers. Needs Node.js. Have a doctor or pharmacist verify results.

Diffs a live page's accessibility violations against a baseline, stashing uncommitted changes by default or comparing with a branch, and reports new, fixed and pre-existing WCAG issues with selectors and fixes. Locates only, no edits. Runs AccessLint's Chrome and CLI tools via npx.

Runs the AccessLint rule engine against a live page and returns a worklist of WCAG 2.2 violations, each with its DOM selector, source file and line when mapped, evidence and a suggested fix. Locates without editing; sets up a debuggable Chrome and runs the CLI via npx.

Jenkins plugin that turns Jenkins itself into an MCP server: agents can list jobs, trigger and rerun builds, page through and search build logs, and view test results and SCM info. Hosted in the official jenkinsci organization; authenticates with a Jenkins API token over Basic auth.

Sonar's official plugin bringing SonarQube checks into the agent coding loop: secrets-scanning hook, issue fixing, quality gates, coverage and dependency risk; with Vortex analysis on, every edit is checked. Needs SonarQube (free Community Build works), the sonar CLI and Docker.

From Twilio Labs: exposes Twilio's public APIs (SMS, voice, phone numbers, Serverless and more) as MCP tools generated from its OpenAPI specs, with filtering by service or tag. Needs a Twilio API key; marked as a proof of concept.

Shapes the agent's own replies rather than your documents: separates what changed from what was verified, cuts invented confidence, leads with the action and keeps load-bearing caveats. Manually invoked and stays on until you say stop; a script can enable it in CLAUDE.md or AGENTS.md.

Neon's official plugin combining the Neon MCP and skills to manage serverless Postgres: projects and branches, object storage, Functions and the AI Gateway. Signs in to Neon via OAuth the first time you use the MCP.

Connects to PACS and other DICOM servers: query images by patient, study and series, read text from PDF reports embedded in DICOM, and forward series to AI nodes such as segmentation. Needs uv and a YAML config. Not for clinical use or real patient data (per the author).

Analyzes your codebase and generates a render.yaml Blueprint, or creates services directly through the Render MCP, to deploy apps to Render. Maintained by Render and included in OpenAI's curated skills. Needs a Render account and code pushed to GitHub, GitLab or Bitbucket.

Searches 600,000+ studies registered on ClinicalTrials.gov, shows protocols and posted results (efficacy, adverse events), and matches patients to recruiting trials by age, sex, condition and location. Public data, no API key; needs Node.js 24+. Unofficial; results must be reviewed by a doctor.

Applies tiered prefers-reduced-motion handling instead of disabling everything: removes vestibular triggers like parallax and scroll hijacking, softens large movement into short fades, and keeps essential motion. Covers CSS and JS gating for GSAP, Framer Motion and Lenis, per WCAG 2.3.3.

Prisma's official skills: the Prisma ORM CLI, Client query API, connection setup for various databases, a v6 to v7 upgrade guide, and deployment workflows for Prisma Postgres and Compute.

42 official AWS skills for healthcare and life sciences: medical coding and terminology mapping, FHIR/HL7 parsing, claims and prior authorization rules, medical imaging, pharmacoepidemiology and genomics, per US standards. Some need local software. Not for clinical decisions; expert review required.

Pinecone's official plugin: bundles the Pinecone MCP server and /pinecone skill commands to create vector indexes, upsert data, search in plain language, or build a document Q&A assistant with citations from Claude Code. Needs a Pinecone API key (free sign-up); Assistant features also need uv.

Alibaba Cloud's official MCP server: through the DataWorks Open API, agents manage data development nodes and workflows, operate scheduled instances, query Data Map metadata and lineage, and configure data quality rules. Needs an Alibaba Cloud AccessKey.

Helps agents add Auth0 authentication to apps: detects 35+ frameworks and covers login, MFA, SSO, RBAC, JWT validation, migration from other auth providers, and tenant security audits. Maintained by Auth0; needs an Auth0 account (free sign-up).
