/**
 * MCP server configuration.
 *
 * Servers are read from `mcp.json` in the agent directory and, for trusted projects, from
 * `<project>/.pi/mcp.json`. Both use the `mcpServers` shape shared by other MCP clients, so
 * existing configurations can be copied over. Project entries replace global entries with the
 * same name.
 *
 * ```json
 * {
 *   "mcpServers": {
 *     "filesystem": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "."] },
 *     "docs": { "url": "https://example.com/mcp", "headers": { "Authorization": "Bearer ${DOCS_TOKEN}" } },
 *     "sentry": { "url": "https://mcp.sentry.dev/mcp" }
 *   }
 * }
 * ```
 *
 * HTTP servers without an `Authorization` header use OAuth when they answer 401 (sign in with `/mcp`).
 * `"auth": { "provider": "<provider>" }` sends the token of a `/login` provider instead. Project files
 * cannot use it, so a repository cannot pick where the credential goes.
 *
 * The top-level `autoEnableCodemode` (default true) activates the codemode tool when a server
 * with `codemode` exposure connects. A project value overrides the global one.
