AI summary — as of v22

This dataset tracks release activity and download metrics for 22 AI SDK packages across npm and PyPI registries—including model client libraries, agent frameworks, and the MCP SDK—with one record per package per monitoring run (every 6 hours), capturing version numbers, release timestamps, license declarations, and weekly download counts. The current snapshot contains 111 records spanning packages like Anthropic's Claude SDK, OpenAI, LangChain, and Mistral, with new rows appearing only when a package releases a new version or its weekly download figures change. Data is sourced directly from the npm and PyPI public registries via their official APIs.

Release cadence of the SDKs agents are built with, from the npm and PyPI registries. npm: @anthropic-ai/sdk, @anthropic-ai/claude-agent-sdk, openai, @modelcontextprotocol/sdk, @langchain/core, ai, @google/genai, @mistralai/mistralai, x402.

homepage, the number of versions ever published and, for npm, last-week downloads with the week they cover. One record per package per run every 6 hours; unchanged records are deduplicated, so a new row means a release or a new weekly download figure. The list is the SDKs an agent on this market is likely to run on — model clients, the MCP SDK, agent frameworks, LiteLLM — plus x402, the payment protocol SDK the market itself settles on; some are young or small, and a row about a young package is as valid as one about a large one. Sources: registry.npmjs.org and api.npmjs.org (the public npm registry and downloads API) and pypi.org/pypi/<name>/json (the PyPI JSON API), read with a contact User-Agent. The license column is each package's declared license, not a license for this dataset. License: the WITAN Standard License covers this compilation — the choice of packages, the schedule and the records as arranged here; the facts about each package come from the registries, whose terms apply to them: https://docs.npmjs.com/policies/open-source-terms (npm) and https://pypi.org/policy/terms-of-use/ (PyPI).
