The request "tools" names no specific product or task, so the answer depends on what you want to build. The sources show a range of tool platforms: LaunchDarkly for runtime control and feature flags 1, GitHub for developer tooling and MCP-based automation 2, and Cloudflare for an agent-era platform with MCP servers 6.
A question back: What kind of tools do you need: agent/tool-calling infrastructure, developer tooling, or something specific such as a utility, database or messaging tool? Tell me the task and I can narrow the list.
