reasoning.services uses the Model Context Protocol (MCP). If your AI client supports MCP, you can add cognitive tools without leaving your workflow.

Model Context Protocol (MCP)

MCP is an open protocol for connecting AI models to external tools and data sources. Our reasoning tools are MCP servers you can add to any compatible client.

🔌

What is MCP?

The Model Context Protocol allows AI assistants to access external tools through a standardized interface. Instead of being limited to their training data, AI models can invoke structured tools with specific capabilities.

Our cognitive tools (Structured Reflection, Sequential Thinking, Context Switcher, Decision Matrix) are exposed as MCP servers. Your AI client connects to them just like any other MCP service.

⚙️

How It Works

  1. Subscribe and get your API credentials

  2. Add our MCP server endpoints to your client configuration

  3. The tools appear in your AI assistant's available capabilities

  4. Invoke them naturally: "Start a Decision Matrix session for this database choice"

Compatible Clients

Any MCP-compatible client can use reasoning.services. Here are some popular options:

🖥️

Claude Desktop

Anthropic's desktop application with native MCP support. Add reasoning tools directly to your Claude conversations.

Quick Setup

Add reasoning.services to your MCP client configuration:

{
  "mcpServers": {
    "reasoning-services": {
      "url": "https://reasoning.services/mcp",
      "transport": "sse",
      "auth": {
        "type": "bearer",
        "token": "YOUR_API_TOKEN"
      }
    }
  }
}

After configuration, you'll have access to all four cognitive tools: Structured Reflection, Sequential Thinking, Context Switcher, and Decision Matrix.

Direct API Access

Not using an MCP client? You can also access the tools directly via HTTP API.

REST Endpoints

Each cognitive tool has a REST endpoint for direct access. Create sessions, invoke tools, and retrieve results programmatically.

See the documentation for endpoint details.

Authentication

All API access uses Bearer token authentication. Get your API token from your account dashboard after subscribing.

OAuth 2.0 with PKCE for secure token exchange.

Add Cognitive Tools to Your Workflow

$20/month for all four reasoning tools, accessible via MCP or direct API.
