streamable-http-mcp-server
A Spring Boot–integrated MCP server that implements JSON-RPC 2.0 style MCP endpoints over a traditional HTTP REST approach (explicitly not supporting SSE streaming). It provides annotation-based integration for registering MCP tools/functions and supports tool listing and tool invocation (plus initialize/ping).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security-relevant controls (authn/authz, scopes, rate limiting, and detailed error handling) are not described in the README. TLS requirements and secret-handling practices are not documented here; score assumes typical HTTPS in Spring Boot but cannot confirm from provided content.
⚡ Reliability
Best When
You want a lightweight Java/Spring Boot MCP server using synchronous HTTP request/response semantics for tool calls.
Avoid When
You need SSE streaming, strong documented security controls, or detailed interface specifications for automated client generation.
Use Cases
- • Expose backend capabilities as MCP tools to an MCP client/agent via an HTTP endpoint in a Spring Boot application
- • Quickly integrate MCP tool registration in Java/Spring Boot using annotations
- • Implement simple request/response tool calls for scenarios like utility functions (e.g., weather example), health checks (ping), and tool discovery (tools/list)
Not For
- • Use cases requiring SSE/event streaming or incremental token/tool output streaming
- • Production deployments that need clear published security/auth, rate-limit headers, and well-specified error contracts (not described in README)
- • Integrations expecting first-class REST/SDK/OpenAPI contracts beyond Spring Boot annotations
Interface
Authentication
README does not mention authentication/authorization mechanisms for the MCP endpoint.
Pricing
No pricing information provided (likely open-source library/starter, but not stated).
Agent Metadata
Known Gotchas
- ⚠ SSE/streaming is not supported (readme explicitly states no SSE streaming), so agents expecting streamed/incremental results may not work as intended.
- ⚠ Authentication and rate-limit behavior are not documented in the provided README, so agent clients may need to rely on default server behavior or add deployment-level controls.
