Context4D

An MCP server that tells coding assistants which Delphi library to use for a task, how to install it, which units go in the uses clause, the pitfalls, and gives working examples that are compiled against the library. Free to use, no account needed.

Claude Code

claude mcp add --transport http --scope user context4d https://context4d.gdksoftware.com/mcp

Other clients

Any client that speaks MCP over Streamable HTTP can use the same address:

{
  "mcpServers": {
    "context4d": {
      "type": "http",
      "url": "https://context4d.gdksoftware.com/mcp"
    }
  }
}

Tools

find_library, get_library, get_example, search_examples and get_idiom. Ask your assistant something like "which Delphi library reads an xlsx file" and it will call them.

Questions that find nothing are logged, without any identity, so the catalog can grow where it is needed. Source and catalog: github.com/cmgeuze/Context4D.
