Description

Many teams connecting LLMs to external tools eventually encounter the same architectural issue: as more tools and agents are added, the integration pattern becomes an N×M mesh of direct connections. Each agent implements its own auth, retries, rate limiting, and logging; each tool needs credentials distributed to multiple places and observability becomes fragmented.We built LLM gateway with this goal to provide a single place to manage authentication, authorization, routing, and observability for MCP servers, with a path toward a more general agent-gateway architecture in the future.The system includes a central MCP registry, support for OAuth2/DCR integration, Virtual MCP Servers for curated toolsets, and a playground for experimenting with tool calls.Resources -Architecture Blog – Covers the N×M problem, gateway motivation, design choices, auth layers, Virtual MCP Servers, and the overall model.https://www.truefoundry.com/blog/introducing-truefoundry-mcp...Tutorial – Step-by-step guide to writing an MCP server, adding Okta-based OAuth, and integrating it with the Gateway.https://docs.truefoundry.com/docs/ai-gateway/mcp-server-oaut...Feedback on gaps and edge cases is welcome.https://www.truefoundry.com/mcp-gateway

Could you build this?

Partial A basic reverse proxy relaying Model Context Protocol (MCP) JSON-RPC calls is easy to assemble, but enterprise-grade gateway features like unified authentication, dynamic tool discovery, distributed rate-limiting, and connection pooling require sophisticated systems engineering.

What it would actually take: A production-grade MCP Gateway is typically built in Go or Rust using an async event-driven proxy layer, Redis for distributed rate limits and caching, and an OIDC/OAuth2 authorization service. The hard part is managing persistent bi-directional transports (SSE, WebSockets, stdio wrappers) at scale while maintaining robust fault tolerance, credential isolation, and sub-millisecond routing latency.

Discussion

3 comments analyzed.

Competitors mentioned: LLM Gateway, MCP Gateway

Concerns raised: Auth propagation complexity when agent backend invokes MCP server instead of client, Original user's auth context lost during tool invocation, Tools requiring user session_id only see generic token

Feature requests: Granular budget and rate controls, Extended tool composition inside Virtual MCP Servers, Richer audit traces, Standardized auth pattern for M2M-issued short-lived tokens and per-request user metadata injection
