Developer Tools / AI Protocols & Infrastructure
HDTP is a protocol specification for agent-to-agent communication on behalf of people, centered on certificates, contact approval, per-caller permissions, and sealed end-to-end calls.
The page clearly presents a real AI-adjacent product/specification with substantial public-facing evidence: purpose, connection flow, permission tiers, comparison with other protocols, security model, conformance testing, and a released PDF whitepaper. It is useful for builders working on agent communication and infrastructure, and the page provides enough detail to support a directory listing.
The page does not show a runnable SDK, public code repository, or implementation docs beyond the spec and whitepaper. It also leaves it unclear how a builder would integrate HDTP today, beyond reading the specification and waitlisting for related products.

CodeGraph is a local code knowledge graph for AI coding agents like Claude Code, Cursor, Codex, OpenCode, and Hermes Agent. It aims to cut token use, tool calls, and runtime by letting agents query pre-indexed code structure instead of scanning files repeatedly.
Mercemur is a store automation platform with three interfaces: a REST API, an MCP server for AI agents, and a CLI for editing storefronts as files. The docs show authentication, scopes, rate limits, error handling, pagination, idempotency, and a large API surface for catalogue, orders, customers, pricing, and money.
Lumae is a free native macOS screen recorder and screenshot tool for polished demos, with automatic zooms, cursor smoothing, motion blur, captions, voiceover, and annotated screenshots. It also exposes editing commands over MCP so agents like Claude Code or Claude Desktop can edit projects directly.
A zero-dependency C++23 CLI and MCP server that gives coding agents a ranked map of a repository, including call context, blast radius, and tests to run.
