Tools

Salesforce's official hosted MCP servers: after an admin enables them in Setup with an OAuth external client app, agents can query and update CRM records and run Flows under the user's permissions. Needs Enterprise Edition or higher, or a free Developer Edition org. Repo holds docs and Q&A.

Lets agents view, create and update Zendesk tickets and comments, read Help Center articles as a knowledge base, and use built-in prompts for ticket analysis and reply drafting. Each support rep signs in with OAuth after an admin registers an OAuth client. Install from source.

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.

Official MCP (beta) from payments and POS platform Square: lets agents query and manage transactions, orders, refunds, invoices, inventory and customers for reconciliation and reporting. Hosted, with Square OAuth sign-in, nothing to install; confirm refunds and other writes manually.

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.

PostHog's official plugin with a built-in MCP and 30+ skills: query product analytics, feature flags, A/B experiments, dashboards and error tracking from chat, and optionally send Claude Code sessions to LLM Analytics. Needs OAuth sign-in with a PostHog account.

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.

MLflow's official skills plugin: lets coding agents add MLflow Tracing to LLM apps, analyze failed traces, build evaluation datasets and scorers, and query token and latency metrics, closing the instrument, evaluate, iterate loop. Needs MLflow 3.8+.

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.

Discourse's official MCP: lets agents search and read forum topics and posts and view categories and users. Read-only by default and no account needed for public forums; posting and replying require a site API key and the --allow_writes flag. Needs Node.js 24+.

Trello's official hosted MCP, maintained by Atlassian: after OAuth authorization of one workspace, agents can search boards, create and move cards, maintain checklists and tidy the inbox, without permanently deleting data. Works on any Trello plan.

Lets agents create, search, update and reply to Freshdesk tickets, add internal notes, and look up contacts, companies and agents, so support teams can process and summarize tickets in bulk. Needs a Freshdesk API key and account domain; runs locally with uvx.

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.

Typefully's official skill: lets agents draft posts and long threads and schedule or publish them to X, LinkedIn, Threads, Bluesky, Mastodon and Substack Notes, and view scheduled content. Needs a Typefully account and API key, plus Node.js 18+.

Drafts US-law contracts: the agent gathers terms for standard templates (NDA, SAFE, offer letter, cloud services agreement) and outputs a DOCX to review in Word, plus guides and checklists citing source law. Use the hosted URL, or run locally for sensitive matters. Drafts only; a lawyer must review.

Contentful's official MCP: content and marketing teams can create, edit and publish entries and assets in bulk using plain language, and manage localized content and scheduled publishing. Needs a Space ID, a management API token and Node.js; protected environments guard live content.

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).

Airtable's official plugin for Claude Code, Codex and Cursor: connects the official Airtable MCP and adds filtering, CLI, and product, marketing and sales ops skills, so agents can create tables, define fields, read and write records, and build shared views. Needs Airtable account authorization.
