Provides a send_email tool that sends emails through Gmail SMTP using configured Gmail account credentials.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
A Model Context Protocol (MCP) server that exposes a small toolbox (math, web search, email, and time tools) to an AI agent, plus a client that connects a Groq-hosted LLM (via LangChain + LangGraph) to that server so it can decide, on its own, which tool to call to answer a question.
Built as a course project, extending the MCP server/agent pattern taught in class into a fuller, better-documented project.

SerpAPI Gmail SMTPThe client never hard-codes what a tool's inputs look like: it asks the
server for its tool list (name, description, JSON Schema) and builds a
matching Pydantic model automatically. Add a new tool to server.py and the
client picks it up on the next run with no changes needed on its side.

Every tool degrades gracefully with a clear error message if its key is missing, so you can run the project with only some keys set.
Terminal 1 -- start the tool server:
