C++26 paper reference MCP server

This is a small helper that connects your AI assistant to a reference library of C++26 standard papers. It is handy if you write C++ and want your assistant to suggest modern, standards-based code instead of older patterns. You do not need to be a compiler expert to use it.

What this MCP server does

You ask your AI something about C++26, like how to write a modern enum-to-string function. The AI uses this helper to search the paper library and find the relevant proposals. The helper returns the paper title, the problem it solves, the key syntax, an example, and the older way of doing it. The AI then uses that to write an answer that follows the C++26 standard. It can also tell you whether clang, gcc, msvc, or a special clang build have shipped each feature yet.

What you can do with it

• Look up a specific C++26 paper by its number, like P2996
• Search the paper library by topic or keyword
• Check which compilers support a given C++26 feature
• Get the canonical example and gotchas for a paper
• See the pre-C++26 equivalent of a modern feature
• Find related papers on the same topic
• Ground your AI's answers in the actual proposal text

Try asking your AI

• “Look up paper P2996 and explain what it does”
• “Search the C++26 papers for contracts and show me the top results”
• “What is the compiler support status for P2996?”
• “Show me the pre-C++26 way to do what P1306 describes”

What it gives back to you

You get back plain text answers in the chat. For a paper lookup, you see the title, problem statement, key syntax, a code example, the older equivalent, and any gotchas. For a search, you get a ranked list of matching papers. For compiler status, you get a small table showing none, partial, or shipped for each compiler.

Who it's for

C++ developers and students who want their AI assistant to suggest modern C++26 code and cite the actual standard papers.
