The record

Purpose: Agentgateway is an open-source HTTP and gRPC gateway for routing, securing, observing, and governing service, LLM, MCP, and agent-to-agent traffic.
LLM routing: Its LLM gateway provides an OpenAI-compatible API for providers including OpenAI, Anthropic, Bedrock, Gemini, Vertex, and OSS Llama runs.
Inference: Self-hosted inference routing supports vLLM, TGI, and Triton, with latency-aware, cost-aware, and model-aware routing.
MCP and A2A: The gateway supports MCP server discovery, scoped tool calls and audit trails, and A2A routing between LangChain, CrewAI, ADK, and other runtimes.
Security: Listed security features include JWT and OIDC, API keys, authorization policies, TLS and mTLS with certificate rotation, and rate limiting.
Guardrails: MCP guardrails inspect calls and responses for prompt injection and unsafe payloads, while prompt guards support checks and redaction.
Observability: The site describes OpenTelemetry by default, Prometheus token-usage histograms, Jaeger traces, and request logs with latency, token counts, and realized USD cost.
Cost controls: Features include scoped virtual keys, per-key or per-team token and dollar spend caps, and a dashboard grouped by model, provider, and user.
Integrations: The site lists model integrations including OpenAI, Anthropic, Gemini, Bedrock, Azure OpenAI, Mistral, DeepSeek, Ollama, Vertex AI, xAI, and Snowflake.
Deployment: The maker describes deployment options as a standalone binary, Docker, or Kubernetes.
Intended users: The site invites tool-builders, platform engineers, and AI enthusiasts to join the community and describes the controls as suited to platform teams.
Support: The enterprise page lists partner-provided commercial support, including a Solo.io offer with 24×7 coverage, upstream collaboration, and best-practice guidance.
Project stewardship: The enterprise page says agentgateway was originally created by Solo.io and is an AAIF project.
