🧠 MCP Server/Client builder

MCP (Model Context Protocol) is an open-source standard for connecting AI applications to external systems.

Using MCP, AI applications like Claude or ChatGPT can connect to data sources (e.g. local files, databases), tools (e.g. search engines, calculators) and workflows (e.g. specialized prompts)—enabling them to access key information and perform tasks.

Think of MCP like a USB-C port for AI applications.

Just as USB-C provides a standardized way to connect electronic devices, MCP provides a standardized way to connect AI applications to external systems.

💡 Working in progress

[ ] 🐛 Update MCP json schema to 2025-11-25: parser error
[ ] 🔧 Client MCP comming soon…
[ ] 🩺 Update deps gbr_... - [ ] Finish deps gbr and publish hex version. - [ ] Update here gleam.toml to deps gbr_... published.

🚀 Installing

gleam add gbr_mcp@1

🛠️ Usage

🧩 MCP JSON Schema Loading

import gbr/mcp/loader

pub fn main() -> Nil {
  let path = "./priv/2025-06-18-schema.json"
  let field = "definitions"
  let output = "./src/gbr/mcp/defs.gleam"

  case loader.load_file_write(path, field, output) {
    Ok(Nil) -> io.println("> Definitions write to " <> output)
    Error(err) -> io.println_error(err)
  }
}
