The Model Context Protocol (MCP) is an open standard, introduced by Anthropic in November 2024, that defines a uniform way for AI applications to connect to external tools, data sources, and services. It uses JSON-RPC 2.0 messaging so that any compliant AI client can discover and use any compliant server without bespoke integration code.
Why it matters
MCP solves the "M×N integration problem": instead of building a custom connector for every model-to-tool pairing, developers expose data once through a standard interface that any AI client can consume. For knowledge workers and consultants, this means the tools holding their research, documents, and notes can be made available to AI assistants in a consistent, portable way. By late 2025 it had been adopted across ChatGPT, Gemini, Cursor, Microsoft Copilot, and VS Code, and governance was donated to a Linux Foundation fund, making it a de facto industry standard rather than a single-vendor feature.
How Pith relates
Pith ships an MCP server, so the cited wiki and bookmarks it builds from your reading can be queried directly by MCP-compatible AI clients such as Claude or ChatGPT. This lets an assistant pull from your source-grounded knowledge base without you copying and pasting context. Pith implements the standard rather than inventing a proprietary protocol, so your data stays portable across the tools you already use.
