What is the LiteLLM (LLM Proxy & Spend Tracking) MCP Server?
Connect your LiteLLM Proxy instance to any AI agent and take full control of your LLM infrastructure, load balancing, and spend management through natural conversation.
What you can do
- Key Orchestration — Generate and manage proxy API keys to isolate distinct microservices or teams, including precise budget and rate limit constraints directly from your agent
- Model Routing Intelligence — Get detailed info on fallback paths (e.g., OpenAI -> Anthropic -> Groq) and verify exact routing endpoints assigned to your models
- Real-time Spend Audit — Track total USD consumed by specific end-users or teams and monitor budget ceilings to ensure cost-effective AI deployments
- Dynamic Model Control — Inject fresh routing endpoints (e.g., new AWS Bedrock or Azure OpenAI deployments) into your proxy runtime with zero downtime
- Team & Organizational Isolation — Create and manage team profiles to track exact cost limits and operational boundaries per organizational division
- Infrastructure Security — Instantly vaporize malicious or leaked keys and remove broken LLM deployments to prevent downstream 500 errors dynamically
How it works
- Subscribe to this server
- Enter your LiteLLM API URL and Master Key
- Start managing your LLM gateway from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Platform Engineers — manage global LLM gateway configurations and audit model fallback paths through natural conversation
- AI Ops Teams — monitor real-time AI spending and adjust team budgets across multiple LLM providers
- Backend Developers — generate sub-keys for new microservices and verify model routing availability without leaving your IDE
Built-in capabilities (10)
Inject completely fresh routing endpoints (ex: new Bedrock Llama 4 endpoints)
Generate pristine organizational isolation tracking exact cost limits per division
Insert specific End-User identities bridging Vinkius with Proxy logs
Delete an existing LLM proxy key entirely
Delete explicitly routed LLM deployments preventing 500s dynamically
Generate a new proxy API key isolating distinct microservices or teams
Get configuration and budget bounds for a specific LiteLLM API Key
Get array endpoints tracing exact Fallback paths like OpenAI -> Anthropic
Get internal logic bounds matching multiple routing users via Team UUID
Return precise End-User abstractions tracking total USD consumed natively

Frequently asked questions
Can I check the budget and rate limits for a specific proxy key?
Yes. Use the get_key_info tool with the specific Key ID. Your agent will retrieve the exact rate limits, budget constraints, and current RPM usage associated with that token.
How do I see the model fallback paths configured in my proxy?
The get_model_info tool allows your agent to extract the global model directory. You'll see the exact fallback chains (e.g., if OpenAI fails, use Anthropic) and the physical endpoints assigned to each model name.
Can my agent create a new team to track specific division costs?
Absolutely. Use the create_team tool and provide a JSON payload defining the team name and optional budget limits. Your agent will provision the new team identity in LiteLLM, allowing for precise organizational cost tracking.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
