Open source. Open possibilities.

nexus-vscode is an MCP proxy extension for VSCode and Cursor that forwards AI tool calls to Unreal Engine (UE) instances.

An unofficial MCP server that gives AI assistants seven read-only tools to search, list and read any Fumadocs documentation site, working against a deployed URL or a local docs repo via a single npx command.

Python and MCP example for an Apify actor that returns US House and Senate congressional stock trades and financial disclosures as structured JSON, with filters for member, ticker, and date range.

HarnessDesk is an MIT-licensed macOS developer preview that acts as a vendor-neutral control plane for coding agents such as Codex, Claude Code, Cursor, Gemini CLI and other ACP agents, adding shared history, permissions, handoffs, audit logs, worktrees and usage views.

Open Kioku is a local repository intelligence tool for AI coding agents. It indexes codebases locally to provide context, generate bounded edit plans, and verify actual diffs against those plans.

Toki is a local-first macOS menu bar app that tracks token usage, costs, and active work time across AI coding agents like Claude Code, Codex, Cursor, Gemini CLI, and more. It provides six focused views for daily totals, projects, models, sources, work time, and hourly usage, with optional encrypted remote sync.

Open-source playbook pack for AI coding tools (Cursor, Claude Code, Codex CLI, Gemini CLI) with 145+ agent skills, 57 slash commands and MCP templates, automating full development workflows from onboarding to shipping, tuned for React/Next.js/Supabase.

Context Engineering Protocol provides AI coding-agent skills that assemble human-approved, source-attributed context packages — code graphs, requirements, org conventions, and constraints — before generation runs. It detects gaps, conflicts, and staleness across sources, gates output behind explicit human approval, and supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex.

coding-agents-mcp is an MCP gateway and orchestrator for autonomous AI coding agents like Claude Code, Antigravity, Codex, and Cursor. It enables IDEs and desktop assistants to delegate tasks with session memory, Git worktree sandboxing, and inter-agent handoffs.

AI Limits is a Chrome side-panel extension that tracks subscription usage and reset timing across twenty AI providers, normalizing each provider's quota into a single Used or Left view with local history graphs.

An MCP server for Godot 4 that provides AI clients with bidirectional control over the Godot editor, featuring live-tree editing, a step-debugger, and 231 specialized tools.

An AI-first engineering toolkit that provides specialized knowledge, workflows, and standards to turn AI coding agents into senior mobile engineers.

CodeAgent Mobile clients provide CLI, VS Code/Cursor/Windsurf, and JetBrains plugins to control AI coding agents (Claude Code, Copilot, etc.) from a phone or dashboard, enabling remote approval and workflow continuity.
