Perplexity

Run precise legal fee splits in your LangChain pipelines

The `apportion_legal_fees` tool executes exact, auditable proportional math to distribute judicial awards directly within your reasoning chains. Your agent runs the numbers, deducts contingency percentages, and forwards the clean ledger output to the next node without manual math checks. By connecting this MCP Server to your multi-step pipelines, you eliminate rounding errors across co-defendant groups. Every calculation step passes through LangSmith, giving you a transparent trace of how your agent divided a $1.5M award among five parties.

Chain award calculations with live case documents

The `apportion_legal_fees` tool handles the raw math while your LangChain agent pulls the liability percentages directly from parsed court documents. You do not need to hardcode fee structures or write custom math libraries. This MCP integration lets your agent decide when to run the numbers based on intermediate chain outputs. If a document reveals a new co-defendant, the agent automatically recalculates the proportional split down to the penny.

Trace every legal fee deduction with LangSmith

The `apportion_legal_fees` tool outputs a deterministic ledger that your LangChain agent can pass to any database or reporting tool. Every input parameter and math step is recorded in your agent's execution history for instant auditing. Because the math happens in an isolated sandbox, you avoid execution errors in production. You see exactly what went into the formula and what came out, directly inside your LangSmith dashboard.
