Add MCP base app samples for Node.js, Python, Go, and .NET by Copilot · Pull Request #1 · trustinbtc/copilot-sdk

Copilot · 2026-07-15T12:53:29Z

Adds minimal runnable sample apps demonstrating MCP server integration across all four primary SDK languages, using @modelcontextprotocol/server-filesystem as the reference server.

Pattern (TypeScript example)

const session = await client.createSession({
    onPermissionRequest: approveAll,
    mcpServers: {
        filesystem: {
            type: "local",
            command: "npx",
            args: ["-y", "@modelcontextprotocol/server-filesystem", "/tmp"],
            tools: ["*"],
        },
    },
});

const result = await session.sendAndWait({ prompt: "List the files in the allowed directory" });
console.log(result?.data.content);

Each sample follows the same shape: create client → open session with MCP config → send prompt → print response. Go uses copilot.NewClient(nil) (respects COPILOT_CLI_PATH); Node.js/Python/.NET bundle the CLI automatically.

Pull request overview

Adds minimal, runnable MCP integration samples across the Node.js, Python, Go, and .NET Copilot SDKs, using the @modelcontextprotocol/server-filesystem MCP server to demonstrate configuring MCP servers on a session and sending a prompt.

Changes:

Added new MCP sample apps for Node.js, Python, Go, and .NET that configure a local stdio MCP server and print the assistant response.
Added Go sample module updates (go.mod / go.sum) to reflect indirect dependencies needed by the samples module.
