## Verdicts

**Agent Development Kit (ADK).** Python, TypeScript, Go, Java and Kotlin. Two critical CVEs in 2026, one of them in tool confirmation itself.

**LangGraph.** Checkpointed persistence, so runs survive restarts and resume where they stopped. No MCP client of its own. LangChain's langchain.mcp is in beta.

## Before you call either

### Agent Development Kit (ADK)

1. Upgrade to 2.5.0 or later before relying on tool confirmation
2. Always pass tool_filter to McpToolset
3. Pin a 2.x minor and read the changelog's breaking section before each bump
4. Install the bigquery-analytics extra if you use pyarrow, since 2.7.0
5. Keep ADK Web off public interfaces, or run 1.28.1 or later at the least

### LangGraph

1. Use a persistent checkpointer in production, not the in-memory one
2. Move from langchain-mcp-adapters to langchain.mcp, and expect a LangChainBetaWarning
3. Set LANGGRAPH_CLI_NO_ANALYTICS=1 on build machines
4. Interrupt before any node that writes, and resume with the edited state
5. Keep the checkpoint and SQLite packages current. Each had a high-severity advisory in late 2025
