Artifact: MCP Server Config -- Before and After

Adding an MCP server entry to a project's config -- exercises co-08.

Before (project MCP config -- no servers configured yet):

{
  "mcpServers": {}
}

Agent's tool list before this change (built-in tools only):

read_file, write_file, edit_file, run_shell, grep, glob

After (a project-docs server entry added, naming the command and args that launch it -- the Host-configuration shape the MCP spec's client-configuration examples use):

{
  "mcpServers": {
    "project-docs": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "./docs"]
    }
  }
}

Agent's tool list after restart (the built-in tools, plus three new ones the project-docs server exposed during MCP's initialization handshake):

read_file, write_file, edit_file, run_shell, grep, glob,
project-docs__list_directory, project-docs__read_file, project-docs__search_files
