Portkey AI Gateway MCP Server
MCP server for Portkey — the AI gateway providing unified access to 250+ LLMs with built-in observability, caching, fallbacks, and load balancing. Enables AI agents to route requests through Portkey's intelligent gateway — getting automatic retry, provider failover, prompt caching, and full observability across any LLM provider.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
LLM prompts and responses pass through Portkey. SOC2. Virtual keys protect provider credentials. Review prompt data retention.
⚡ Reliability
Best When
An agent developer wants a unified gateway for multiple LLM providers — getting automatic failover, caching, cost tracking, and observability across OpenAI, Anthropic, Gemini, and others from a single endpoint.
Avoid When
Data sovereignty requires no intermediary. FINANCIAL RISK: LLM costs via gateway can accumulate quickly — implement usage limits and monitoring.
Use Cases
- • Routing LLM requests through Portkey gateway for automatic failover from agent orchestration layers
- • Accessing observability logs and LLM usage analytics from monitoring agents
- • Managing virtual keys and LLM provider routing from API governance agents
- • Implementing semantic caching for agent workflows to reduce LLM costs
Not For
- • Direct LLM provider access without routing/observability needs (use provider APIs directly)
- • High-security environments where data must not pass through third-party gateways
- • Non-LLM workloads
Interface
Authentication
Portkey API key authentication. Virtual keys for underlying LLM providers — never expose raw provider keys to agents. Portkey manages provider credentials.
Pricing
Portkey charges on top of LLM provider costs. Overhead is small vs. value of observability and routing.
Agent Metadata
Known Gotchas
- ⚠ FINANCIAL RISK: All LLM costs route through Portkey — monitor usage across all provider calls
- ⚠ Data passes through Portkey servers — not suitable for air-gapped or high-security data
- ⚠ Virtual keys abstract provider credentials — agents never see raw API keys
- ⚠ Prompt logs stored in Portkey — review data retention policies for sensitive prompts
- ⚠ Community MCP — verify against latest Portkey API version
