mcp-gateway
An MCP (Model Context Protocol) gateway/registry that centralizes MCP server discovery and management, virtualizes HTTP services as MCP tools, and exposes MCP-compatible transports (e.g., HTTP JSON-RPC, SSE, WebSocket, streamable HTTP, stdio bridge) behind an enterprise-style API gateway with authentication, RBAC, rate limiting, logging/auditing, and content filtering.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README claims JWT Auth, OAuth2/OIDC, RBAC with fine-grained permissions, API key management, and rate limiting backed by Redis with memory fallback, plus content filtering (PII detection/regex/custom filters) and audit trails. However, provided content does not include concrete security controls details (TLS requirements, token validation specifics, session/storage handling, header policies) or dependency/SBOM/CVE evidence.
⚡ Reliability
Best When
You need an MCP gateway that you can self-host, integrating auth/RBAC/rate limiting and offering multiple transports to LLM agents.
Avoid When
You need a simple unauthenticated MCP endpoint or you cannot provide the required infrastructure (Docker/Postgres/Redis) and configuration management.
Use Cases
- • Expose multiple MCP servers under a unified gateway with namespaces
- • Convert existing REST/HTTP services into MCP tools with schema validation
- • Allow external/internal agents to securely access different sets of MCP tools
- • Provide centralized authentication, RBAC, audit logs, and rate limiting for MCP tool execution
- • Bridge different transport types (HTTP/SSE/WebSocket/streamable HTTP) to MCP-compatible clients
Not For
- • A lightweight, single-binary tool proxy for small experiments
- • Environments that require guaranteed managed uptime without self-hosting ops
- • Teams needing a fully specified public OpenAPI contract or SDKs (not evidenced in provided content)
Interface
Authentication
README indicates JWT Auth, OAuth2, OIDC, and RBAC with fine-grained permissions plus API key management. Exact flows, endpoints, scope model, and how to obtain tokens are not present in the provided content.
Pricing
No pricing information in provided content (appears self-hosted/open-source).
Agent Metadata
Known Gotchas
- ⚠ Gateway behavior depends on correct configuration of auth/RBAC and namespace/server discovery.
- ⚠ Multi-transport support (SSE/WebSocket/streamable HTTP/stdio bridge) may require different client handling patterns and timeouts.
- ⚠ Rate limiting details (limits, headers, retry windows) are not shown in the provided README content.
