Definition
An MCP routing decision is the branch an agent makes when it has multiple MCP servers connected and must choose one (or several) to fulfill a step. The decision is shaped by query type, cost per call, freshness requirements, and which server has the right surface.
In Depth
Once an agent has more than one MCP server attached — say, a Postgres MCP, a GitHub MCP, and a multi-platform search MCP — every tool-using turn becomes a routing problem. Naive setups send every query to the first server and waste calls. Better setups expose tool descriptions that the model uses to route: SERP queries to Scavio's MCP, schema lookups to Postgres MCP, code search to GitHub MCP. The discipline of writing precise MCP tool descriptions becomes the single biggest lever on agent quality once a stack has three or more MCP servers.
Example Usage
The agent's MCP routing decision sent product questions to the Amazon search MCP, code questions to the GitHub MCP, and SEO questions to the Scavio MCP.
