Model Context Protocol Wrapped*
The AI interop protocol that just took off
*Only applies to 2025 — the first year MCP has ever existed. Give it a break!
MCP was all about engaging with the community on GitHub this year
Not Just An Experiment
modelcontextprotocol/modelcontextprotocol
More and more developers paid attention to MCP this year, and all the improvements to its spec, proving it's not just a small project anymore

Discuss, Discuss Some More
Here are the most chatty proposals that had a direct impact on the direction of the specification
Hotly Debated Topic
Some of the most chatty topics for discussion were around, not surprisingly, security - developers and organizational leaders want to make sure their data is secure when consumed by LLMs
MCP Just Kept Shipping
This year, the MCP community released three major spec updates (2025-03-26, 2025-06-18, and 2025-11-25), launched the MCP Registry to make server discovery a breeze, adopted OAuth-based authorization for secure remote servers, started using Elicitations for interactive prompts and Tasks for async operations, and saw adoption grow with companies across the industry.
But it's not just the spec repo that kept growing...

The MCP Ecosystem
Stars across all modelcontextprotocol repositories
The MCP Registry Public Preview started gaining steam this year too!
MCP Registry
The community came together to index MCP servers in one centralized registry
Server Distribution
Remote servers are hosted endpoints, local servers are packages you run yourself
Remote Server Transports
There's two ways in which remote servers can communicate (although SSE is deprecated now)
Local Server Packages
Package registries used by local MCP servers
Distribution Method Of Choice
We also grew our own home where contributors hang out!

What a Year!
To everyone who adopted MCP, built clients and servers, contributed code, reported issues, and helped shape the future of AI interoperability—this year wouldn't have been possible without you. The community's passion and dedication have transformed MCP from a protocol into a movement.
