LLM Gateway MCP server
Lets your AI assistant chat with any model, generate images, browse models and check usage and costs on LLM Gateway.
This is the hosted MCP server of LLM Gateway, an API gateway for many AI models. You connect your client to its address with an API key from your dashboard.
Your assistant can read usage and cost reports, list models, send messages to other models and generate images. The chat and image tools are billed to the workspace that issued the key.
Good for
- LLM Gateway users who track spend by model, provider and coding app
- Claude Code users who want a second model to review code
- Developers who generate images from their assistant

Tools
Shows who you are connected as
Shows the connected user, organization, project, role and any API key spending limits. Owners and admins also see the organization's credit balance, and credentials are never returned.
Try: “Which LLM Gateway project and role am I connected as?”
Read ·
get-accountShows your usage and costs
Returns request and token totals, errors, cache hits, costs and a time series for a date range, plus your most-used provider, model and coding app.
Try: “Show my usage and costs for the last 30 days.”
Read ·
get-usageRanks providers, models, apps or keys
Ranks providers, models, coding apps or API keys by requests, cost or tokens, with paging.
Try: “Which coding app accounts for the most cost this month?”

chatGenerates an image from a prompt
Generates one to four images from a text prompt with an image model, defaulting to qwen-image-3.0. Image generation is billed to your workspace.
Try: “Generate a minimalist blue logo for my startup.”
Write ·
generate-imageGenerates an image with Gemini 3 Pro
Generates an image with Gemini 3 Pro Image and returns an inline preview. The hosted server returns it inline without writing files, since saving needs a server upload directory.
Try: “Create a 16:9 hero image for my landing page.”

Medium risk
It can run paid model calls and image generation on the workspace behind your API key. Use a key for the project you want to expose, and watch its spending limits.
What it can do
- Read your data
- Create and change things
- Delete things
- Read-only mode
Watch out for
Chat and image tools spend your credits
chat, generate-image and generate-nano-banana are billed to the workspace that issued the key. Spending limits on the key or member still apply to them. docs.llmgateway.io
The API key sits in your client config
The key is sent as a Bearer header, so it is stored in the config file. Use a key limited to one project and rotate it if the file is shared. docs.llmgateway.io
Usage tools only read your own scope
Owners and admins see the project's usage across keys, and developers see only keys they created. The tools cannot override scope. docs.llmgateway.io

Questions
Is the LLM Gateway MCP server official?
Yes. It is the hosted server of LLM Gateway itself, with its code in the LLM Gateway repository.
What is the LLM Gateway MCP server URL?
The address is https://api.llmgateway.io/mcp, and https://llmgateway.io/mcp also works. Send your API key in an Authorization Bearer header.
Do I need an API key?
Yes. Create one on the API Keys page of your LLM Gateway dashboard. A DevPass plan key also works, with model IDs written without a provider prefix.
Which clients are documented?
The docs cover Claude Code, Codex and Cursor, and describe the plain HTTP endpoint for other clients.
Does it cost money?
Reading usage and listing models do not run models, and the docs say analytics tools incur no model charges. Chat and image generation are billed to the workspace that issued the key.
Can it run read-only?
No read-only switch is documented. The analytics tools are read-only, and the chat and image tools spend credits.
Can it see other people's usage?
Owners and admins see the project's usage across keys. Developers see only the keys they created. A project key never reaches another project or organization.
Does it save images to my disk?
Not on the hosted server. The docs say saving needs an upload directory configured on the server, and otherwise images come back inline.
