Amey-Thakur MCP multi-server orchestration
Each server is designed in isolation and they meet in one agent's tool list. Two servers with a search tool, forty tools where twelve are relevant, and no indication which system an action affects: these are integration problems no individual server can solve.
Method
- Namespace tools by server. Prefixed names make ownership obvious to both the agent and the person reading the transcript, and prevent silent collisions.
- Expose only the tools the task needs. Tool selection degrades as the list grows, so filtering per task or per agent beats connecting everything (see agent-specialist-router).
- Give each agent its own server set. In a multi-agent system, scoping servers per role limits both confusion and blast radius (see agent-context-isolation).
- Resolve overlapping capability explicitly. When two servers can do the same thing, the instructions must say which is authoritative for what, or the choice is arbitrary per call.
- Isolate credentials per server. One server's compromise must not reach another's access, which means separate scoped tokens rather than a shared identity (see mcp-authentication).
- Handle partial availability. One server being down should degrade capability rather than failing the agent, which requires the agent to know what it lost.
- Log which server served each call. Debugging a multi-server agent without attribution is guesswork (see audit-logging).
Boundaries
Orchestration manages the surface; it cannot fix a badly designed tool on an upstream server. More servers means more failure modes and more latency variance. Tool count has a practical ceiling beyond which selection accuracy falls regardless of naming.
