openui_mcp 0.0.1-dev.2

MCP `ToolProvider` for OpenUI Flutter. Wraps `mcp_dart`'s `McpClient` with the JS-reference-compatible `extractToolResult` envelope unwrap.

openui_mcp

MCP ToolProvider for OpenUI Flutter.

Wraps mcp_dart's McpClient and exposes a ToolProvider to the OpenUI Lang runtime. The extractToolResult envelope unwrap from openui_core mirrors the JS reference:

1. result.isError → throw McpToolError(messageJoinedFromTextContent)
2. result.structuredContent != null → return it
3. otherwise join TextContent.text, attempt jsonDecode, fall back to the raw string

Status

v0.1, Phase 4 complete.

Install

dependencies:
  openui_mcp: ^0.1.0

Quick start

import 'package:mcp_dart/mcp_dart.dart';
import 'package:openui/openui.dart';
import 'package:openui_components/openui_components.dart';
import 'package:openui_mcp/openui_mcp.dart';

final client = McpClient(...);                  // connect your transport
await client.connect();
final provider = McpToolProvider.from(client);

Renderer(
  response: response,
  library: openuiLibrary(),
  toolProvider: provider,                       // → Query / Mutation calls
);

The renderer routes Query(name: "...", args: {...}) statements through provider.callTool, which forwards to mcp.McpClient.callTool and runs the result through extractToolResult before caching the value under the statement id.
