Best AI tools for developers
Most developers already have a coding assistant. What separates a useful one from a frustrating one is what it can reach: current documentation instead of a stale memory of it, the whole codebase instead of one open file, the issue tracker, the browser where the bug shows up. This page lists the MCP servers and agent skills that give an assistant that reach.
Extend the agent you have before you switch
Switching from one coding agent to another costs a week of new habits. Adding a documentation server or a code search server to the agent you already use costs one command, and it fixes the most common failure: the model writing code against an API that changed last year.
For the agents themselves, see the AI coding tools page. This page is about what you plug into them.
How to judge a developer MCP server
Check who publishes it. An official server from the company behind the service, such as GitHub's own, tends to keep up with the API. A community server can be better, but look at the last commit date and the open issues.
Check what it can touch. A server that can run shell commands or write files can do real damage on a bad prompt, so prefer servers with read-only modes, and scope tokens to the repos they need.
Count your servers. Every server adds tool descriptions to the model's context, and a dozen idle ones make every answer slower and vaguer. Keep the three or four you use each day.

Questions
What is the difference between an MCP server and a skill for developers?
An MCP server gives the assistant a new ability, such as reading GitHub issues or driving a browser. A skill gives it a way of working, such as how your team writes commit messages or reviews code. Most setups use both.
Do these work outside Claude Code?
MCP is an open protocol, so most servers also work in Cursor, VS Code, Windsurf and other clients that support it. Skills written as SKILL.md folders are read by Claude Code and a growing number of other agents.
