Tiny-OAI-MCP-Agent provides a small, extensible agent architecture built on the OpenAI API. It implements a multi-cognitive process (MCP) loop for reasoning, memory, and tool usage. You define tools (APIs, file operations, code execution), and the agent plans tasks, recalls context, invokes tools, and iterates on results. This minimal codebase allows developers to experiment with autonomous workflows, custom heuristics, and advanced prompt patterns while handling API calls, state management, and error recovery automatically.

pyafai is an open-source Python library designed to help developers architect, configure, and execute autonomous AI agents. It offers pluggable modules for memory management to retain context, tool integration for external API calls, observers for environment monitoring, planners for decision making, and an orchestrator to run agent loops. Logging and monitoring features provide visibility into agent performance and behavior. pyafai supports major LLM providers out of the box, enables custom module creation, and reduces boilerplate so teams can rapidly prototype virtual assistants, research bots, and automation workflows with full control over each component.

AgentServe provides a unified interface for creating and deploying AI agents. Users define agent behaviors in configuration files or code, integrate external tools or knowledge sources, and expose agents over REST endpoints. The framework handles model routing, parallel requests, health checks, logging, and metrics out of the box. AgentServe’s modular design allows plugging in new models, custom tools, or scheduling policies, making it ideal for building chatbots, automated workflows, and multi-agent systems in a scalable, maintainable way.

crewAI Playground is a developer toolkit and sandbox for building and experimenting with AI-driven agents. You define agents via configuration files or code, specifying prompts, tools, and memory modules. The playground runs multiple agents concurrently, handles message routing, and logs conversation history. It supports plugin integrations for external data sources, customizable memory backends (in-memory or persistent), and a web interface for testing. Use it to prototype chatbots, virtual assistants, and automated workflows before production deployment.

Nefi.ai is a cloud-based platform for designing, training, and orchestrating AI-powered agents without writing code. It offers a visual canvas to assemble blocks like LLM modules, vector database retrieval, external API calls, conditional logic, and memory stores. Agents can be trained on custom documents or linked to enterprise data. Once built, they deploy as chatbots, email assistants, or scheduled tasks. Advanced features include monitoring dashboards, version control, role-based access, and integrations with Slack, Teams, and Zapier.
