developer tools

An open agent-identity protocol with a shipped reference implementation, TypeScript SDK, conformance test vectors, and protocol docs for identity, discovery, payments, and audit flows.

A native macOS app that uses Claude to act as an autonomous coding agent for Apple platform development. It can inspect an Xcode project, make edits, build, launch, and validate changes with xcodebuildmcp and UI automation.

A local tool that estimates GitHub Copilot AI-credit costs from usage data and generates an HTML report. It pulls from VS Code, OpenCode, Pi, Copilot CLI, and Copilot for Xcode, with CLI options for date ranges, model mapping, and JSON output.

Open-source harness for executable security regression testing of agentic applications and MCP-integrated systems, with scenario files, policy assertions, trace-based evaluation, and JSON output for CI or local use.

Open-source procedural memory for coding agents that learns from successful and failed sessions, then reuses that knowledge to reduce repeated work.

A member-governed AI inference service with chat, a developer API, and governance features. The site highlights sliding-scale membership, monthly usage credits, OpenAI-compatible access, and options focused on privacy, renewable energy, and publicly developed models.

Enzyme is a local-first tool that helps coding agents index and search Markdown knowledge bases, then pull relevant notes with citations. It is aimed at Obsidian-style vaults, meeting notes, and agent memory written in Markdown.

A Claude Code mod that prevents runaway subagent fan-out, heavy-context prompts, and retry loops from burning through usage limits too quickly.

A read-only MCP server that lets AI agents search and read a user's WhatsApp messages, with deployment on Cloudflare Workers and support for Claude and other MCP clients.

A web tool for estimating how fast local LLMs will run on different hardware before you buy it. It lets users browse by GPU, Mac, CPU, and model, and shows simulated tokens/sec and time-to-first-token based on benchmark data.

A guardrails and knowledge-layer tool for coding agents. It briefs agents before tasks, verifies rules with checks, and flags drift when governed files change. Works with Claude Code and other MCP agents.

A Claude Code mod that adds debugger-like controls for tool calls, including breakpoints, step/reject, timeline inspection, and failure diagnosis.

Rinkata is a shared project context layer for teams using coding agents, with knowledge capture, goal tracking, decision handling, and evidence packs for completed work.

Botscent is a lightweight library that detects AI agents visiting a site and can identify which agent is behind a request when evidence is available. It includes both a server-side signal check and a small client-side script, with docs, FAQ, and GitHub links shown on the page.

Favz indexes public GitHub repos to show which MCP servers, skills, plugins, and agent configs people actually set up. It tracks rising tools, compares stars with real usage, and includes a CLI/plugin angle for monitoring your own setup.

Open-source semantic layer for warehouses that infers table, column, join, and business-rule metadata, then serves it to AI agents through MCP and CLI checks.

A reverse proxy for OpenAI-compatible agent traffic that detects runaway tool loops and enforces hourly and daily spend caps with zero payload retention.

Project-local MCP server that lets existing agents discover each other, share status, and exchange durable direct messages with explicit acknowledgement.

A tiny programming language for AI agents that bakes in permissions, bounded retries, verification, and a tamper-evident audit log.

An MCP server that converts public URLs into clean Markdown for AI agents and MCP-compatible clients. The repo includes setup instructions, a usage example, a direct API option, and notes on supported clients like Claude Desktop and Cursor.

A repo for keeping coding agents from overengineering by injecting a ruleset during coding and running a slop-check after edits. It supports multiple agent setups, including Claude Code, Codex, OpenCode, Cursor, Copilot, and generic AGENTS.md-based workflows.

Kodama is a portable, provider-neutral multi-agent pack for the Kiro CLI. It ships one orchestrator plus eight specialist agents, with install options for Kiro Crew or standalone use, and includes CLI commands for memory, health checks, updates, and uninstall.

Open-source terminal app for multi-agent coding that lets one lead agent coordinate a team, manage worktrees, and keep the user in one thread.

Hotpath records an AI agent run once, compiles the trace into an editable workflow, and replays it with only the judgment-heavy steps still using an LLM.
