Provides secure file system access with configurable allowed directories. Supports reading, writing, listing, searching, and moving files. The official reference server for local file operations in Claude Desktop.

Exposes Git repository operations — reading commits, diffs, branches, and file contents — directly to your AI agent. Lets Claude understand and navigate codebases without spawning shell processes.

Fetches web pages and converts them to clean Markdown, making web content accessible to Claude without browser overhead. Handles redirects, respects robots.txt, and optionally returns raw HTML.

Gives AI agents persistent memory via a knowledge graph stored locally. Supports creating, reading, updating, and deleting entities and relations so Claude can remember facts across conversations.

Provides a structured tool for multi-step reasoning and problem decomposition. Claude uses it to break complex tasks into sequential thoughts, backtrack when needed, and produce well-reasoned final answers.

Provides current date and time in any timezone and converts between timezones. A simple, indispensable reference server that gives Claude accurate temporal context without hallucination.

A comprehensive test and demo server that implements every MCP feature: prompts, resources, tools, sampling, and logging. The definitive reference for MCP server authors learning the full protocol.

Full GitHub API integration — manages repos, issues, pull requests, code search, file reads, and branch operations. The official server for AI-driven GitHub workflows in Claude Desktop.

Integrates Claude with GitLab projects, merge requests, issues, pipelines, and repositories. Supports self-hosted GitLab instances as well as GitLab.com via personal access tokens.

Queries Sentry issues, events, and stack traces so Claude can help diagnose production errors. Fetch recent exceptions, drill into specific error groups, and get AI-powered root cause analysis.

Triggers workflows, reads run logs, and queries job statuses on GitHub Actions via the GitHub REST API. Let Claude investigate flaky CI runs and trigger deploys without leaving your chat.

Queries Datadog metrics, monitors, logs, and dashboards via the Datadog API. Claude can diagnose performance anomalies, review alert history, and correlate traces with logs in one conversation.
