An MCP server that gives agents IDE powers: symbol and reference lookup, symbol-level edits and renames via LSP or JetBrains
MCP servers
An MCP server connects an agent to external data and tools over a single protocol: files, databases, APIs and services. This section lists servers with their transport, auth method and environment variables, an install command and an honest read on the risks.

Frequently asked questions
What is an MCP server?
An MCP server connects an agent to external data and tools over a single protocol: files, databases, APIs and services. The agent calls its tools while it works.
How do I connect an MCP server to an agent?
The entry lists how to run it (npx, uvx, docker or a remote URL) and the environment variables. A config snippet goes into the agent settings.
Do I need a key or a paid account?
It depends on the server. Each entry states the auth method and requirements, including paid accounts, in the limitations block.
