@robot-resources/router-mcp

MCP server for managing Robot Resources Router — stats, config, and model comparison.

What is Robot Resources?

Human Resources, but for your AI agents.

Robot Resources cuts your LLM API costs by 60-90%. It runs a local proxy that classifies each prompt by task type (coding, reasoning, analysis, simple Q&A, creative, general) and routes it to the cheapest model that can handle it — across 14 models from OpenAI, Anthropic, and Google.

Your API keys never leave your machine. Free, unlimited, no tiers.

Install the full suite

npx robot-resources

One command sets up the Router proxy, configures your agents, and gets you saving immediately.

About this MCP server

This package gives AI agents management tools for the Router proxy via the Model Context Protocol. Use it to check cost savings, compare models, and adjust routing config — all from within Claude Desktop, Claude Code, or any MCP-compatible agent.

Quick Start

npx @robot-resources/router-mcp

Requires the Router proxy running at localhost:3838 (default). Override with ROUTER_URL env var.

Configuration

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "router": {
      "command": "npx",
      "args": ["-y", "@robot-resources/router-mcp"]
    }
  }
}

Claude Code

Add to your .mcp.json:

{
  "mcpServers": {
    "router": {
      "command": "npx",
      "args": ["-y", "@robot-resources/router-mcp"]
    }
  }
}

Custom Router URL

If the proxy runs on a non-default port:

{
  "mcpServers": {
    "router": {
      "command": "npx",
      "args": ["-y", "@robot-resources/router-mcp"],
      "env": {
        "ROUTER_URL": "http://localhost:4000"
      }
    }
  }
}

Tools

router_get_stats

Cost savings statistics for the Router proxy.

Parameter	Type	Default	Description
period	"daily" | "weekly" | "monthly"	"weekly"	Time period
task_type	string	—	Filter by task type
provider	string	—	Filter by provider

router_compare_models

Compare models by capability and cost for a given task type.

Parameter	Type	Default	Description
task_type	string	required	Task type to compare
threshold	number	0.7	Minimum capability score
provider	string	—	Filter by provider

router_get_config

Read current routing configuration (provider scope, thresholds, overrides).

No parameters required.

router_set_config

Update routing configuration at runtime. Changes are in-memory only (reset on restart).

Parameter	Type	Description
provider_scope	string	Limit to specific provider(s)
capability_threshold	number	Minimum capability score
baseline_model	string	Model for cost comparisons
log_level	string	Logging level

Pass null for any field to reset it to the env-var default.

Requirements
