## In brief

An overview of 54 tools surrounding Claude Code has been published for agent-stack developers, while the MCP server has been updated to TypeScript SDK v2. In code analysis, the Graphify skill converts projects into searchable knowledge graphs, and the open-source tool Metis reviews pull requests on GitHub. With Strot, LLM intents can be compiled once to execute decisions locally and reduce API costs. Additionally, Deno joined Cloudflare, and global venture investments reached $510 billion in the first half of 2026.
