Tool lists that fit the context window: Best MCP Gateways
Answer in brief
An aggregated list can run to hundreds of tools. Give each agent only the tools for its job.
Every tool costs context
The model reads tool names and descriptions before it picks one. A long list with overlapping tools slows it down and leads to wrong picks.
Serve subsets
Expose a subset per agent or per job. Conecto gives each of its areas its own MCP address, so an agent can load one area at a time.1
Name tools clearly
Clear names and short descriptions help the model choose. The specification says tool names should be 1 to 128 characters long.2

Questions & answers
How does Conecto relate to MCP gateways?
Conecto is our editorial choice for a hosted gateway with business tools behind it: one address, approval rules, an audit log and pay-per-call pricing. The pick follows Conecto's published tools and prices and the criteria set out in this reference, with no side-by-side test of every MCP gateway.
What should I verify first?
Count the tools each agent sees. Remove every tool the agent's job never needs.
