Overview

Mcp Sentiment is a dedicated MCP server that brings real‑time sentiment analysis to AI assistants. By exposing a simple, well‑defined set of tools and prompts, it allows Claude (or any MCP‑compatible client) to query the emotional tone of arbitrary text—whether it’s a customer review, a social media post, or a transcript of an interview. This capability is especially valuable for developers building conversational agents that need to adapt their responses based on user mood or contextual sentiment.

The server implements a handful of intuitive endpoints. A tool accepts raw text and returns a sentiment score along with categorical labels such as “positive,” “neutral,” or “negative.” The prompt template can be injected into the assistant’s chain to automatically call this tool whenever sentiment insight is required. Because the server is built on Gradio, it comes with a lightweight UI that developers can use to test the tool locally or expose it as a public API. The integration is seamless: an MCP client simply calls the tool by name, passes the text payload, and receives a structured JSON response that can be parsed or visualized downstream.

Key features include:

• Fast, deterministic inference using a lightweight transformer model fine‑tuned for sentiment classification.
• Rich metadata in the response, such as confidence scores and token‑level explanations, enabling developers to build explainable AI workflows.
• Extensible prompt templates that let you embed sentiment checks into broader reasoning chains without hard‑coding logic.
• Built‑in UI for quick prototyping and debugging, reducing the friction of adding sentiment analysis to a new project.

Typical use cases span customer support automation (detecting frustration or delight), content moderation, marketing analytics, and any scenario where understanding the emotional undertone of text can improve decision‑making or user experience. For example, an AI tutor could lower the tone of its feedback if a student’s message shows signs of anxiety, or a social media bot could flag posts with highly negative sentiment for human review.

By integrating Mcp Sentiment into an MCP‑driven workflow, developers gain a reusable, standards‑compliant tool that can be combined with other MCP servers (e.g., summarization or translation) to create sophisticated, sentiment‑aware AI applications without writing custom inference code.
