Released on August 12, 2025, v0.2.0 brings a significant modernization to how mcp-acronym-lookup connects to the world. This release focuses on simplifying network transport and enhancing the metadata provided to AI agents, ensuring a smoother and more reliable experience.

What’s new

Streamable HTTP Transport

The most impactful change in this release is the transition from Server-Sent Events (SSE) to Streamable HTTP transport. This modernization simplifies the server’s network footprint by consolidating connectivity into a single endpoint: /mcp.

To accommodate this change, the command-line interface has been updated. Users should now use the --http flag instead of the previous --sse flag when starting the server in network mode.

Smarter Agent Integration

We’ve enhanced the lookupAcronym tool with additional annotations to provide better context for AI agents. The tool now includes a descriptive title (“Lookup Acronym”) and a read-only hint. These additions explicitly signal to the agent that the tool is designed for information retrieval and does not modify any underlying state.

Why it matters

Simplified Setup

By moving to a single /mcp endpoint and a streamlined HTTP transport, the complexity of configuring remote access is significantly reduced. This makes it easier to deploy the server in containerized or cloud environments where simplified routing is a priority.

Better AI Reliability

Clearer metadata is the key to better agent performance. By providing explicit titles and read-only hints, AI agents can more accurately identify the correct tool for the task and call it with higher confidence, reducing hallucinations and improving the overall precision of acronym lookups.

Getting Started with v0.2.0

Upgrading to v0.2.0 is straightforward. You can download the latest pre-compiled binaries from the GitHub Releases page or install directly using Go:

go install github.com/UnitVectorY-Labs/mcp-acronym-lookup@latest

Important Note for Existing Users: If your current workflow relies on the --sse flag, please update your startup commands to use --http and point your clients to the new /mcp endpoint to maintain connectivity.
