MCPilled

MCPilled is a lightweight MCP server designed to serve as a living archive of the Model Context Protocol’s evolution. Rather than exposing traditional data‑access tools, it focuses on tracking and cataloguing the milestones, feature releases, and pivotal events that shape MCP itself. This approach gives developers a single, authoritative source of truth about the protocol’s history and status, enabling them to stay current without hunting through scattered release notes or community forums.

The server provides a structured API that returns concise records for each event: the date, description, affected MCP components (e.g., resources, prompts, sampling rules), and links to related documentation or issue trackers. By exposing these entries through the standard MCP interface, an AI assistant can query “What new sampling feature was added in version 1.2?” or “When did the first public tool integration occur?” and receive an instant, machine‑readable answer. This eliminates the need for custom web scrapers or manual lookups, streamlining knowledge‑gathering workflows.

Key capabilities include:

• Event cataloguing: Each milestone is stored as a structured entry, making it easy to filter by date, component, or type of change.
• Version tracking: The server automatically associates events with MCP version numbers, allowing developers to map protocol changes to their own deployments.
• Linkage to external resources: URLs to GitHub issues, pull requests, or community discussions are embedded in each entry, providing quick access to deeper context.
• Searchable API: Clients can query by keyword, tag, or date range, enabling fine‑grained retrieval of protocol history.

Typical use cases span from continuous integration pipelines that validate compatibility with the latest MCP release, to developer onboarding tools that present newcomers with a timeline of significant protocol developments. For AI assistants, MCPilled serves as an on‑demand knowledge base that can be queried alongside other data sources—helping to answer questions about MCP’s evolution, recommend best‑practice tool usage, or flag deprecated features.

What sets MCPilled apart is its dedicated focus on the protocol’s own lifecycle. While other MCP servers expose generic resources or computational tools, this server offers a curated, searchable history that is invaluable for maintaining alignment with MCP’s evolving standards. By integrating seamlessly into existing AI workflows, it empowers developers to keep their applications up‑to‑date with minimal effort.
