Microsoft Translator's translation quality tool: GPT scores each sentence using MQM error categories or a direct score; --list_mqm_errors shows error types and severity. Needs line-aligned source and target files, Python and an OpenAI or Azure OpenAI key (paid); a translator should still review.

Slack's official plugin: connects the Slack-hosted MCP to search messages and files, send or schedule messages, and read and write canvases. Includes commands for channel summaries and standup reports, plus skills for building Slack apps. Requires workspace admin approval.

Connects any FHIR-compliant EHR server (e.g. the Epic sandbox or HAPI) to agents to search, read, create and update patient clinical data in plain language, with SMART on FHIR auth. By WSO2. Needs a FHIR server URL, access token and uv; clinicians must review results.

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.

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.

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.

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.

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.

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).

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.

Official MCP for Paddle, the merchant of record: manage products and prices, customers, subscriptions, transactions and refunds from chat, download invoice PDFs and generate financial reports. Needs a Paddle Billing account and API key; start in sandbox with read-only or non-destructive tools.

Official CLI for Weblate, the open-source translation platform: check translation progress for projects and components, upload and download translation files, lock components, and commit or push repository changes. Hosted or self-hosted; needs the server URL, an API key and Python.

Netlify's official plugin with skills for Functions, Edge Functions, Blobs, databases, forms, caching, netlify.toml configuration and deploys, plus the hosted Netlify MCP (OAuth sign-in on first use).

GitGuardian's official MCP: scans code for leaked secrets with 500+ detectors, and lets agents triage and remediate incidents, generate honeytokens and open fix PRs. Needs a GitGuardian account; the hosted endpoint with OAuth sign-in is recommended.

Postman's official plugin: sets up the Postman MCP server so Claude Code can sync collections, run API tests and diagnose failures, generate client code, create mocks and docs, and run OWASP API security checks. Needs a Postman account.

Snowflake's official plugin: detects Snowflake-related requests and hands them to the Cortex Code CLI, whose 55+ built-in skills handle SQL, dynamic tables, data governance and more. Needs the cortex CLI installed and a Snowflake connection configured.

Lets agents upload, download and list files in Tencent Cloud Object Storage (COS), and use Cloud Infinite for image processing, QR code recognition, document-to-PDF conversion, video frame capture and natural-language search. Maintained by Tencent Cloud; needs a SecretId and SecretKey.

Supabase's official plugin: Supabase and Postgres best-practice skills plus the Supabase remote MCP to manage projects, run SQL, design schemas and RLS policies, and handle auth and storage. Needs a Supabase account.

Langfuse's official plugin: uses hooks to send prompts, model calls, token usage and cost, tool calls and subagents from Claude Code sessions to Langfuse as traces for monitoring and review. Needs Langfuse keys (self-hosting supported) and uv or Python 3.10+.

ModelScope's official MCP: search models, datasets, Studio apps, papers and MCP servers and view details, plus text-to-image and image-to-image generation. Needs a ModelScope API token.
