Report #75439

[frontier] Static tool lists fail when agents need to discover capabilities dynamically in production multi-agent systems

Treat MCP servers as capability registries: query /resources and /tools endpoints at runtime to dynamically assemble agent prompts with available capabilities, rather than hardcoding tool definitions

Journey Context:
Traditional agents define tools statically in code, requiring redeployment when capabilities change. Leading teams now use MCP's Resources and Sampling primitives to treat tool servers as dynamic capability sources. The agent queries the MCP server at initialization \(and periodically\) to discover available tools AND their schemas, injecting these into the system prompt. This enables 'zero-downtime' capability updates and allows multi-agent systems where agents advertise services via MCP. The tradeoff is increased latency at startup and the need for robust schema validation, but the flexibility wins in microservice-like agent architectures.
