LocalAbout MindBridge MCP Server ⚡ The AI Router for Big Brain Moves
MindBridge is an MCP server that gives apps one unified API for many LLMs, including OpenAI, Anthropic, DeepSeek and Ollama. It suits developers who need to route, compare or combine model calls across providers.
Key features
- 01Unified access to multiple LLM providers
- 02Routing aware of reasoning-focused models
- 03getSecondOpinion tool for side-by-side model answers
- 04OpenAI-compatible API layer
- 05Automatic provider discovery from configured keys
- 06Configuration through env vars, MCP config or JSON
Use cases
- 01Routing requests to different models by task complexity
- 02Comparing several models' answers to the same question
- 03Managing model calls from Cursor or Windsurf
MCP support
MindBridge runs as an MCP server and exposes tools such as getSecondOpinion, listProviders and listReasoningModels to MCP clients.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

MindBridge MCP Server ⚡ The AI Router for Big Brain Moves
MindBridge is your AI command hub — a Model Context Protocol (MCP) server built to unify, organize, and supercharge your LLM workflows.
Forget vendor lock-in. Forget juggling a dozen APIs.
MindBridge connects your apps to any model, from OpenAI and Anthropic to Ollama and DeepSeek — and lets them talk to each other like a team of expert consultants.
Need raw speed? Grab a cheap model.
Need complex reasoning? Route it to a specialist.
Want a second opinion? MindBridge has that built in.
This isn't just model aggregation. It's model orchestration.
Core Features 🔥
| What it does | Why you should use it |
|---|---|
| Multi-LLM Support | Instantly switch between OpenAI, Anthropic, Google, DeepSeek, OpenRouter, Ollama (local models), and OpenAI-compatible APIs. |
| Reasoning Engine Aware | Smart routing to models built for deep reasoning like Claude, GPT-4o, DeepSeek Reasoner, etc. |
| getSecondOpinion Tool | Ask multiple models the same question to compare responses side-by-side. |
| OpenAI-Compatible API Layer | Drop MindBridge into any tool expecting OpenAI endpoints (Azure, Together.ai, Groq, etc.). |
| Auto-Detects Providers | Just add your keys. MindBridge handles setup & discovery automagically. |
| Flexible as Hell | Configure everything via env vars, MCP config, or JSON — it's your call. |
Why MindBridge?
"Every LLM is good at something. MindBridge makes them work together."
Perfect for:
- Agent builders
- Multi-model workflows
- AI orchestration engines
- Reasoning-heavy tasks
- Building smarter AI dev environments
- LLM-powered backends
- Anyone tired of vendor walled gardens

Configuration ⚙️
Environment Variables
The server supports the following environment variables:
OPENAI_API_KEY: Your OpenAI API keyANTHROPIC_API_KEY: Your Anthropic API keyDEEPSEEK_API_KEY: Your DeepSeek API keyGOOGLE_API_KEY: Your Google AI API keyOPENROUTER_API_KEY: Your OpenRouter API keyOLLAMA_BASE_URL: Ollama instance URL (default: http://localhost:11434)OPENAI_COMPATIBLE_API_KEY: (Optional) API key for OpenAI-compatible servicesOPENAI_COMPATIBLE_API_BASE_URL: Base URL for OpenAI-compatible servicesOPENAI_COMPATIBLE_API_MODELS: Comma-separated list of available models
MCP Configuration
For use with MCP-compatible IDEs like Cursor or Windsurf, you can use the following configuration in your mcp.json file:
{
"mcpServers": {
"mindbridge": {
"command": "npx",
"args": [
"-y",
"@pinkpixel/mindbridge"
],
"env": {
"OPENAI_API_KEY": "OPENAI_API_KEY_HERE",
"ANTHROPIC_API_KEY": "ANTHROPIC_API_KEY_HERE",
"GOOGLE_API_KEY": "GOOGLE_API_KEY_HERE",
"DEEPSEEK_API_KEY": "DEEPSEEK_API_KEY_HERE",
"OPENROUTER_API_KEY": "OPENROUTER_API_KEY_HERE"
},
"provider_config": {
"openai": {
"default_model": "gpt-4o"
},
"anthropic": {
"default_model": "claude-3-5-sonnet-20241022"
},
"google": {
"default_model": "gemini-2.0-flash"
},
"deepseek": {
"default_model": "deepseek-chat"
},
"openrouter": {
"default_model": "openai/gpt-4o"
},
"ollama": {
"base_url": "http://localhost:11434",
"default_model": "llama3"
},
"openai_compatible": {
"api_key": "API_KEY_HERE_OR_REMOVE_IF_NOT_NEEDED",
"base_url": "FULL_API_URL_HERE",
"available_models": ["MODEL1", "MODEL2"],
"default_model": "MODEL1"
}
},
"default_params": {
"temperature": 0.7,
"reasoning_effort": "medium"
},
"alwaysAllow": [
"getSecondOpinion",

"listReasoningModels"
]
}
}
}
Replace the API keys with your actual keys. For the OpenAI-compatible configuration, you can remove the api_key field if the service doesn't require authentication.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
