Steel exposes a browser API that manages Chrome sessions, pages, processes, cookies, local storage, proxies, extensions, and cleanup for AI agents or automation applications. Developers can connect with Puppeteer, Playwright, or Selenium, or call quick endpoints for scraping pages, taking screenshots, and producing PDFs. It can be used through Steel Cloud or deployed locally with Docker and other supported setups. The project is still described as a public beta.

MCP Registry exposes a searchable list of MCP servers to clients and provides an API, publisher tooling, and a locally runnable service for maintainers. Publishing verifies namespace ownership through GitHub OAuth, GitHub OIDC, DNS, or HTTP challenges. The documented service remains in preview, with the v0.1 API temporarily frozen for integration validation rather than declared generally available.

Letta offers a CLI and TypeScript Agent SDK for running agents with advanced memory, either fully locally, in its cloud, or against a self-hosted App Server. This repository mainly retains the legacy Letta Server behind the V1 API and SDKs; active development has moved to the Letta Agent repository, and new projects are encouraged to use the newer Agent SDK.

Anthropic Skills collects Claude skill examples, the Agent Skills specification, and a starter template for document, development, enterprise, communication, and creative tasks. The repository can be registered as a Claude Code plugin marketplace, and its example skills can also be used through Claude.ai or the API. A custom skill is a directory containing a SKILL.md file with YAML frontmatter and instructions. Most examples use Apache 2.0, while the document-creation skills are source-available rather than open source.
