Q&A: Planner Agent Architecture and Multi-MCP Orchestration

[AGI-Corporation]

Overview

Route.X serves as the orchestration backbone for our agentic workflows. At the heart of this system is the Planner Agent, which leverages a high-density reasoning model to decompose complex user intents into executable sequences across 300+ MCP servers.

Q1: How does the Planner Agent handle conflict resolution between multiple MCP servers?

A1: The Planner Agent uses a hierarchical priority queue. When two MCP servers offer overlapping capabilities, the Planner evaluates their "cost-to-complete" metrics and historical reliability scores stored in the local vector DB.

Q2: Is the orchestration stateless or does it maintain a global world-state?

A2: Route.X maintains a dynamic state graph. Every action taken by a sub-agent or MCP server updates this graph, allowing the Planner to re-route in real-time if an unexpected state change occurs.

Q3: How do we ensure low-latency planning with such a high number of servers?

A3: We implement Capability Indexing. Instead of polling 300+ servers, the Planner queries a metadata index that classifies servers by intent, reducing the search space to a relevant subset (usually < 5) before finalizing the execution plan.
