Arenukvern MCP Flutter Flutter MCP Toolkit Intentcall Migration

intentcall migration — MCPCallEntry → AgentCallEntry

Phase 6b hard cut: MCPCallEntry is removed from mcp_toolkit. App code must use AgentCallEntry (from intentcall_core, re-exported by mcp_toolkit).

Canonical doc: migration_intentcall_phase6.md

When to use this skill

• dart analyze reports undefined MCPCallEntry after pulling intentcall Phase 6
• User asks to migrate custom tools/resources to the new API
• Before shipping a major mcp_toolkit bump to consumers

CLI (preferred)

# Preview (exit 1 if changes pending)
flutter-mcp-toolkit migrate agent-entries --check lib/

# Apply
flutter-mcp-toolkit migrate agent-entries --write lib/
flutter-mcp-toolkit migrate agent-entries --write --namespace my_app lib/main.dart

Alias: migrate mcp-call-entry (same behavior).

After migration — registration

• MCPToolkitBinding.addEntries(entries: Set<AgentCallEntry>)
• bootstrapFlutter(additionalEntries: { ... })
• addMcpTool(AgentCallEntry) — still a shortcut for a single entry

Handlers should return AgentResult (AgentResult.success / AgentResult.failure). For legacy MCPCallResult + MCPToolDefinition handlers, use mcpToolkitTool / mcpToolkitResource (see flutter-mcp-toolkit-custom-tools).

Legacy pattern (before — do not ship new code)

// BEFORE (removed in Phase 6b)
final tool = MCPCallEntry.tool(
  handler: (request) async => MCPCallResult(
    message: 'ok',
    parameters: {'n': request['n']},
  ),
  definition: MCPToolDefinition(
    name: 'my_tool',
    description: 'Example',
    inputSchema: {'type': 'object', 'properties': {}},
  ),
);

Target pattern (after)

import 'package:mcp_toolkit/mcp_toolkit.dart';

final tool = AgentCallEntry.tool(
  namespace: 'app',
  name: 'my_tool',
  description: 'Example',
  inputSchema: const {
    'type': 'object',
    'additionalProperties': false,
    'properties': {'n': {'type': 'string'}},
    'required': ['n'],
  },
  handler: (final args) async {
    final n = args['n']?.toString() ?? '';
    return AgentResult.success(
      message: 'ok',
      data: {'n': n},
    );
  },
);

await MCPToolkitBinding.instance.addEntries(entries: {tool});

Platform sync (optional)

After tool surfaces compile:

flutter-mcp-toolkit codegen sync --platform web
flutter-mcp-toolkit codegen sync --platform android,ios,macos --check

See docs/platform-notes/android-oem.md for Xiaomi/Huawei (same shortcuts XML as AOSP).

MCP migrate tool

fmt_migrate_agent_entries is shipped (report-only by default; apply: true to rewrite). CLI equivalent: flutter-mcp-toolkit migrate agent-entries.

Maintainer checklist (in-repo product gate)

1. flutter-mcp-toolkit migrate agent-entries --check on flutter_test_app/lib
2. make sync-skills after any plugin/skills/ edit
3. cd mcp_server_dart && dart test test/contract/
4. Grep: no MCPCallEntry in skills except this file's BEFORE examples

Phase 7 extract (external monorepo)

When intentcall publishes to pub.dev (see decisions/0009-intentcall-extract.mdx):

1. Replace path: ../agentkit/packages/intentcall_* (or hosted ^0.1.0 after publish) in pubspec.yaml.
2. Run flutter pub get and migrate agent-entries --check again.
3. CI: use make check-intentcall-integration in mcp_flutter; package matrix moves to intentcall repo.

Until then, all intentcall packages remain in-repo with publish_to: none.
