Context7
MCP server and platform that feeds coding agents up-to-date, version-specific library documentation.
IDA Pro MCP
MCP server connecting IDA Pro to language models for AI-assisted reverse engineering.
Figma MCP Server
Figma's MCP server that brings design context from Figma files into coding agents.
IDA MCP (Hex-Rays)
IDA MCP is Hex-Rays' official MCP server for the IDA disassembler and decompiler. It lets AI coding agents and people work on the same IDA databases at the same time, so an agent can inspect functions, types and decompiled code, rename and annotate, and coordinate analysis across several related binaries in one session. It works with the IDA GUI through a plugin or headless through idalib, installs with Hex-Rays' hcli tool, and needs IDA 9.4 or later.
Sentry MCP
Sentry's MCP server and CLI that give coding agents access to Sentry issues, errors and traces for debugging.
Grounded Docs MCP
Self-hosted MCP server that indexes up-to-date documentation from websites, GitHub, npm and PyPI so coding agents query the right version.
