Build sentiment-driven LangChain trading pipelines

`get_social_metrics` pulls raw engagement data directly into your LangChain runnables via this MCP integration. Your agent analyzes spikes in social volume before executing subsequent chain steps. By chaining this tool with your existing execution blocks, you build autonomous workflows that react to sudden market shifts. LangSmith traces every step, showing you the exact social metrics that triggered the agent's decision.

Rank assets using custom MCP Server decision nodes

`get_altrank` measures coin performance against the broader market by comparing social activity and price action. Your agent uses this single metric as a filtering node in a ReAct loop to isolate high-momentum tokens. You can combine this with `list_assets` to scan hundreds of tokens, feeding the filtered output directly into downstream database storage tools. The entire process runs inside a single, observable execution chain.

Validate market conditions with multi-step chains

`get_galaxy_score` evaluates health indicators by combining social sentiment, market momentum, and volume. LangChain agents run this tool to confirm whether a social spike is backed by real market structure. If the score meets your threshold, the chain triggers `get_market_metrics` to check 24-hour transaction volume and liquidity. This prevents your agent from executing trades on low-liquidity assets during social media pumps.
