Agent Toolbelt Overview

The marras0914/agent-toolbelt MCP server exposes 27 stock research and general-purpose utility tools to AI agents. It connects through the Agent Toolbelt API using an API key, with tools for financial analysis, text processing, schemas, prompts, documents, URLs, and developer workflows. Reach for it when an agent needs structured market research or reusable infrastructure utilities without implementing each capability locally. A TypeScript SDK and LangChain wrappers are also available for non-MCP applications.
