Coldtea runs the full SDLC. Agents test every pull request on a real device, watch production, and file what breaks before your users find it.
Mainframe — Watch your agents work.
Mainframe turns agent work into videos your team can keep up with.

New capabilities for building agents on the Anthropic API | Claude
Claude now offers code execution, MCP server connections, file storage, and extended prompt caching through the API—giving developers powerful tools to build agents that analyze data, connect to external systems, and maintain context for longer periods of time.


Tool use with Claude
Connect Claude to external tools and APIs. Learn where tools execute and how the agentic loop works.

openai/openai-realtime-agents
This is a simple demonstration of more advanced, agentic patterns built on top of the Realtime API.
truefoundry/trueforge
The open-source agent harness - the runtime layer that turns an LLM into a working agent.
zonko-ai/harbor-sdk
Connect your agents with anything. Make your tools composable. Secrets stay out of agent context.
Composio toolkits | MCP and API Integrations for AI Agents
Connect your agent to leading SaaS apps in minutes. Secure access to 20,000+ tools via MCP or direct APIs to automate real work.

rivet-dev/agentos
agentOS is a portable open-source operating system for agents. ~6 ms coldstarts, 32x cheaper than sandboxes. Powered by WebAssembly and V8 isolates.
shepherd-agents/shepherd
A runtime substrate that turns an agent's execution into a reversible, Git-like trace, so meta-agents can observe, fork, replay, and revert any run. Couples agent and environments in a copy-on-write fork ~5x faster than docker commit, with ~95% KV-cache reuse on replay. Framework built for meta-agents to supervise, optimize, and train other agents
Temporary Cloudflare Accounts for AI agents
The moment an agent needs to deploy something, it slams face-first into a wall built for humans. Today we're rolling out Temporary Accounts on Cloudflare Workers. Any agent can now run wrangler deploy — temporary and get a live Worker in seconds.

Introducing advanced tool use on the Claude Developer Platform
Claude can now discover, learn, and execute tools dynamically to enable agents that take action in the real world. Here’s how.

Push events into a running session with channels - Claude Code Docs
Use channels to push messages, alerts, and webhooks into your Claude Code session from an MCP server. Forward CI results, chat messages, and monitoring events so Claude can react while you're away.
