It includes a WebSocket listener (port 9000), a simple health endpoint and metrics endpoint, and demonstrates synchronous tool calls as well as a streaming/batched query pattern.","use_cases":["Building an MCP tool for demo/education around Go concurrency and low-latency query handling","Prototyping agent workflows that need read-only dataset querying (albums, songs, tours)","Testing agent integration with MCP tool discovery and tool invocation (including streaming results)","Performance benchmarking of concurrent tool execution in a controlled environment"],"not_for":["Production deployment without adding authentication, authorization, and rate limiting","Use as a source of truth for real Taylor Swift catalog/tour data (mock in-memory dataset)","Handling sensitive or regulated data","Guaranteeing API stability over time (repo appears to be a small demo with minimal observable release/versioning info)"],"best_when":"You want a lightweight MCP server example to integrate with an agent framework quickly and test tool calling + streaming behavior.","avoid_when":"You need secure multi-tenant access, strict governance, or production-grade reliability/operational guarantees out of the box.","alternatives":["Use an existing MCP server implementation with documented auth, rate limiting, and stable tool contracts (community Anthropic/others MCP servers)","Build a REST/GraphQL wrapper over your data and use agent tool calling over an OpenAPI-described API","Use a managed vector/data platform with an MCP adapter (if available) for safer production patterns"],"af_score":38.0,"security_score":32.8,"reliability_score":23.8,"package_type":"mcp_server","discovery_source":["github"],"priority":"low","status":"evaluated","version_evaluated":null,"last_evaluated":"2026-04-04T21:22:15.640814+00:00","interface":{"has_rest_api":false,"has_graphql":false,"has_grpc":false,"has_mcp_server":true,"mcp_server_url":"http://localhost:9000 (WebSocket listener mentioned; exact scheme not specified in README)","has_sdk":false,"sdk_languages":[],"openapi_spec_url":null,"webhooks":false},"auth":{"methods":[],"oauth":false,"scopes":false,"notes":"README does not describe any authentication/authorization mechanism.
