Which one, for what
LangGraph BB
Best for Long-running, stateful agents that pause for people and must survive restarts.
Ahead on
- Reliability, 75 against 67
- Schema & documentation, 89 against 61
- Agent ergonomics, 70 against 61
- Maintenance & community, 90 against 82
- Transparency & trust, 79 against 68
Also in its favour
- Agent-ready, a grade of BB or better
- No key needed to call it
Watch for
No MCP client of its own. LangChain's langchain.mcp is in beta
Best for Researchers who want a fixed multi-agent analysis of one listed instrument or crypto pair on a date, with point-in-time data for backtests, and who will run Python.
Also in its favour
- No incidents deducted, where LangGraph loses 3 points for them
Watch for
No MCP client or MCP server, so an agent drives it only through Python or the CLI

Verdicts
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.
TradingAgents
An Apache 2.0 LangGraph framework at 0.7.0 with six releases in 90 days, a dated changelog with upgrade notes, a public test matrix and point-in-time rules for historical runs. It has no MCP client or server, no PyPI package and no documentation beyond the README, and its output is a model-written rating that places no orders.
Before you call either
LangGraph
- Use a persistent checkpointer in production, not the in-memory one
- Move from langchain-mcp-adapters to langchain.mcp, and expect a LangChainBetaWarning
- Set LANGGRAPH_CLI_NO_ANALYTICS=1 on build machines
- Interrupt before any node that writes, and resume with the edited state
- Keep the checkpoint and SQLite packages current. Each had a high-severity advisory in late 2025
TradingAgents
- Run headless with
tradingagents --ticker <T> --date <YYYY-MM-DD> --analysts market,news,fundamentals --save --no-show; a missing answer stops the run and names the flag - Guard on the REVIEW signal before mapping
propagate()'s decision to a rating; it means no rating could be parsed - Set SEC_EDGAR_USER_AGENT to the operator's own name and address before fetching US fundamentals
- Keep provider keys out of the working directory tree unless intended, since the package loads the nearest .env on import
- Treat the rating as model output for research; the framework places no orders and its results vary between runs
