/mcp servers

Official Brave Search MCP: web, local, image, video, news, places, summarizer, LLM context. STDIO default in 2.x. Needs a Brave Search API key.

Anthropic never published a generic `@anthropic/mcp-server-browser`; their archived Puppeteer server was retired in May 2025. Today the canonical browser MCP is Microsoft's `@playwright/mcp@latest` (accessibility-tree driven). For live Chrome: `browsermcp/mcp` or any of the ~30 community servers in the registry.

Official MCP reference server that fetches a URL and returns markdown. Python via uvx. Can reach local IPs — treat as a security risk. SDK 1.x only until the v2 port lands.

GitHub’s official MCP: remote hosted URL or local Docker image. Repos, issues, PRs, Actions, security toolsets. OAuth or PAT. Not the archived servers-archived GitHub reference.

Official MCP reference server for Git: status, diff, commit, branch, log. Python via uvx. Early development; tools can change. Requires MCP Python SDK 1.x.

Official MCP reference knowledge-graph memory. TypeScript via npx. Educational example from the steering-group repo, not a hosted memory product.

Notion's official MCP — `makenotion/notion-mcp-server` (4.6k stars). Local package `@notionhq/notion-mcp-server@2.5.1` (109,953 weekly downloads, MIT). 22 tools. Notion is also pushing a separate remote Notion MCP with OAuth (preferred for new agents); the local server still works.

Microsoft’s Playwright MCP: browser automation via accessibility snapshots, not screenshots. npx @playwright/mcp@latest. Node 18+.

Anthropic's read-only PostgreSQL MCP is archived. Active alternatives: `crystaldba/postgres-mcp` (3.3k stars; PG + plans + index tuning; stdio or SSE), `supabase/mcp` (managed Postgres), and AWS Labs' Aurora DSQL / RDS / postgres-mcp servers. Use a read-only DB user for production.

Official MCP reference tool sequential_thinking: step, revise, branch. npm package. For hosts that call the tool in a loop, not a production planner product.

Official Supabase MCP. Remote at `https://mcp.supabase.com/mcp` (OAuth), local via `@supabase/mcp-server-supabase@0.12.0` (npm, 109,666 weekly downloads). Apache-2.0. `supabase/mcp` repo (2.9k stars) holds the TypeScript source.

Anthropic's reference SQLite MCP server — schema inspection, read/write queries, and an `append_insight` memo tool. **Archived.** Source lives in modelcontextprotocol/servers-archived. npm still resolves but the archive ships no security guarantees. Point at the MCP Registry for maintained alternatives.

AWS Labs' open-source suite (`awslabs/mcp`, 9.7k stars) plus a managed remote AWS MCP. Pick a specialized server: docs, IaC, EKS, ECS, Lambda, Cost Explorer, CloudWatch, Bedrock KB, Aurora DSQL. AWS recommends the managed `https://aws-mcp.us-east-1.api.aws/mcp` for production agents.

Anthropic never shipped a Docker MCP. The dominant community option is `ckreiling/mcp-server-docker` (743 stars, GPL-3.0). Mounts `/var/run/docker.sock`, covers containers / images / networks / volumes. For agent-managed Compose stacks: `friendlygeorge/docker-mcp-server`.

Official MCP test/reference server. Exercises tools, prompts, resources, sampling, elicitation, tasks. Not a useful production server — for client authors.

Anthropic's Google Drive MCP was archived May 2025. No official replacement. The most common community picks: `rgarcia/hermes-google-drive-mcp` (small, MIT), Composio's hosted gdrive, or any `gdrive` entry in the official MCP Registry. OAuth setup is the same as the archived version.

Atlassian Jira via the community `mcp-atlassian` server. 98 tools for JQL search, issue CRUD, sprints, comments, transitions. Supports Jira Cloud and Server/Data Center.

Anthropic's Slack MCP was archived May 2025. The active maintainer is Zencoder: `@zencoderai/slack-mcp-server` (Apache-2.0, 8 tools, stdio or streamable HTTP). Slack Bot Token + Team ID required.

Stripe's official remote MCP at `https://mcp.stripe.com` (OAuth, HTTP). 100+ read/write tools over the Stripe API plus a Sigma/analytics toolset. Setup via `npm i -g @stripe/cli@latest && stripe agent setup`. MIT-licensed `stripe/ai` repo on GitHub (1.8k stars) hosts the agent plugin and skills.

Official MCP reference server for current time and IANA timezone conversion. Auto-detects local zone. Python via uvx. SDK 1.x until the v2 port lands.
