LangGraph Workflow

LangGraph coordinates multi-step workflows with explicit state transitions:

  1. Ingest source content.

  2. Chunk and embed documents.

  3. Index into vector and graph stores.

  4. Retrieve evidence for a query.

  5. Generate structured reasoning traces.

  6. Evaluate and score the output.

MCP Tooling

All external tools are exposed through Model Context Protocol (MCP) servers. This enforces strict tool boundaries and improves auditability.

Recommended MCP services:

  • mcp-llm: model gateway and routing.

  • mcp-retrieval: hybrid search and re-ranking.

  • mcp-docs: ingestion and document validation.

  • mcp-tools: bioinformatics, code execution, math.

Agent Protocol

Agents follow a shared protocol:

  • Explicit tool calls with typed inputs/outputs.

  • Observable state transitions.

  • Safety and policy checks at each step.
