Llama-Agent is a developer-focused toolkit for creating intelligent AI agents powered by large language models. It offers tool integration to call external APIs or functions, memory management to store and retrieve context, and chain-of-thought planning to break down complex tasks. Agents can execute actions, interact with custom environments, and adapt through a plugin system. As an open-source project, it supports easy extension of core components, enabling rapid experimentation and deployment of automated workflows across various domains.

MCP Agent Tool Adapter acts as a middleware layer between language model-based agents and external tool implementations. By registering function signatures or tool descriptors, the framework automatically parses agent outputs that specify tool calls, dispatches the appropriate adapter, handles input serialization, and returns the result back to the reasoning context. Features include dynamic tool discovery, concurrency control, logging, and error handling pipelines. It supports defining custom tool interfaces and integrating cloud or on-premise services. This enables building complex, multi-tool workflows such as API orchestration, data retrieval, and automated operations without modifying underlying agent code.

Melissa provides a lightweight, extensible architecture for building AI-driven agents without requiring extensive boilerplate code. At its core, the framework leverages a plugin-based system where developers can register custom actions, data connectors, and memory modules. The memory subsystem enables context preservation across interactions, enhancing conversational continuity. Integration adapters allow agents to fetch and process information from APIs, databases, or local files. By combining a straightforward API, CLI tools, and standardized interfaces, Melissa streamlines tasks such as automating customer inquiries, generating dynamic reports, or orchestrating multi-step workflows. The framework is language-agnostic for integration, making it suitable for Python-centric projects and can be deployed on Linux, macOS, or Docker environments.
