developer tools

Open-source, local MCP-based context layer for AI coding assistants. It scans a codebase, builds a behavioral graph, and aims to improve architectural understanding while reducing input-token use on large repos.

Paid public API for finance built on the Neurobro agent. The docs show API key authentication, a single ask endpoint, tier-based modes, billing, rate limits, errors, examples, and a quickstart.

A CLI guard for MCP stdio servers that checks for stdout pollution, handshake failures, invalid JSON-RPC frames, and startup/runtime issues before clients hit them.

A Copilot skill suite that enforces structured coding workflows for AI-assisted development, with design, planning, TDD, debugging, verification, and cleanup steps plus a live task-graph visualization server.

A repository of Claude plugins, managed-agent cookbooks, and connectors for legal workflows like commercial review, privacy, litigation, IP, and regulatory work.

An agent-first web browser for automating web tasks, with Playwright integration and a CLI for browser control, page inspection, screenshots, navigation, and file actions.

A minimal Rust crate for building agentic workflows in applications, with ticket-based orchestration, tools, knowledge storage, schema validation, retries, budget policies, and multi-provider support.

A Codex browser plugin and MCP tool that captures live UI edits as structured implementation intent, with a local collector, installer scripts, and move-mode snapping for precise visual changes.

A CLI for structural code search and refactoring using AST patterns instead of regex. It supports find, replace, delete, and insert workflows, with examples for method renames, logging removal, and code inserts across files.

A pure-Java UI toolkit for building admin panels and internal tools, with AI-agent-friendly structures and examples for human-in-the-loop workflows.

A self-hosted Git LFS server for BYOF setups, with support for GitHub, GitHub Enterprise, GitLab, and S3-compatible storage backends like Cloudflare R2, DigitalOcean Spaces, and Backblaze B2.

Flue is an open-source Python tool that lets coding agents control desktop software from the command line without MCP servers. The README says it works with apps like Photoshop, Blender, Unity, Houdini, and Microsoft Office, and supports harnesses such as Claude Code, Codex, Gemini CLI, Cursor, and OpenCode.

A Claude Code plugin that learns from user corrections and successful runs, then turns them into reusable rules and playbooks stored locally.

A ~1000-line C workflow runtime where an LLM can modify a DAG during execution using a restricted four-verb grammar, with every change written to an append-only audit log for replay and inspection.

A self-hosted TypeScript harness for building provider-neutral LLM agent systems inside an application or platform, with typed agent and workflow runtime, tool support, state, tracing, and example workspaces.

A local-first, file-based context and memory system for AI coding assistants. It’s designed to persist decisions, tasks, and learnings across sessions so tools can rehydrate project context instead of starting from scratch.

Ragnerock is a research intelligence platform that turns raw sources into queryable, structured data. It supports extraction, analysis, and research workflows across SQL, Excel, PDF, HTML, images, and other sources, with audit trails and deployment into existing infrastructure.

Lightport is a lightweight AI gateway that makes LLM providers OpenAI-compatible. The repo shows supported endpoints, a long provider list, quickstart commands, request examples, and active maintenance signals.

A persistent memory layer for AI agents, built as a standard MCP server with local setup, dashboard, and benchmark claims against other memory tools.

A tiny macOS menu bar utility that keeps your Mac awake for long-running agent work, builds, downloads, and other tasks, even with the lid closed.

AgentRQ is a human-in-the-loop task management platform for AI agents, with MCP-based integrations, real-time notifications, and a Vue/Go stack for collaborative workspace workflows.

MCP server for Unreal Editor that exposes a small MCP surface for a large set of editor automation tools. It supports blueprint editing, asset management, animation authoring, trace analysis, PIE actions, and Python execution, with setup notes for Unreal Engine 5.x and MCP-compatible clients.

Conan is a native macOS app that adds a live HUD around Claude Code, showing prompts, tool calls, skills, context usage, and session activity in real time. It’s a paid one-time purchase for Apple silicon Macs.

Offline duplicate-code detector for codebases where AI agents write most of the code. It scans for structurally duplicated functions, tracks duplication over git history, and can fail CI when new code repeats existing logic.
