What it does

Flutter MCP Toolkit Intentcall Migration is an agent skill from Arenukvern/mcp_flutter. Migrate Flutter app code from removed MCPCallEntry to AgentCallEntry after the hard cut. Use when upgrading mcptoolkit, fixing compile errors after a major bump, or running flutter-mcp-toolkit migrate agent-entries.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps and MCP servers. It works with Flutter and Model Context Protocol. The repository describes itself as: MCP Toolkit for Flutter AI Agent Driven Development (MCP/CLI + custom client side tools) - via closed feedback loop (visual & semantic snapshot) and high client side… The licence is MIT.

When your agent uses it

  • Upgrading mcptoolkit
  • Fixing compile errors after a major bump
  • Running flutter-mcp-toolkit migrate agent-entries

Example prompts

  • “/flutter-mcp-toolkit-intentcall-migration”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. flutter-mcp-toolkit migrate agent-entries --check on showcase/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

What it can do on your machine

Read from SKILL.md and the folder at commit 62f3ee1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make
    • dart
    • flutter

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter MCP Toolkit Intentcall Migration loads about 1.1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 277 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

<!-- @FMT_MODE_PRELUDE -->

IntentCall migration — MCPCallEntry → AgentCallEntry

MCPCallEntry is removed from mcp_toolkit. App code must use AgentCallEntry (from intentcall_core, re-exported by mcp_toolkit).

Canonical migration doc: migration_mcp_call_entry_to_agent_call_entry.md

When to use this skill

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

CLI (preferred)

bash
# 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>)
  • addEntries(entries: { ... }) before bootstrapFlutter(runApp: ...)
  • 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)

dart
// 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)

dart
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:

bash
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 showcase/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

Hosted IntentCall packages

IntentCall now lives outside this repository. Normal consumer state uses hosted intentcall_* packages.

  1. Use hosted intentcall_*: ^0.6.0 dependencies for committed consumer state.
  2. Use local path overrides only for deliberate cross-repo development against a local IntentCall checkout.
  3. Run flutter pub get and migrate agent-entries --check again after dependency changes.
  4. CI: use make check-intentcall-hosted-consumer for hosted mcp_flutter proof; use make check-intentcall-sibling-matrix only for deliberate local IntentCall checkout matrix proof. The historical make check-intentcall-integration target is a compatibility alias for the sibling-matrix lane, not a fresh-adopter hosted gate.
