SkillFM LLM Cost Optimizer MCP

LLM cost optimization and provider usage visibility for MCP-capable agents.

This repository is a transparent SkillFM gateway package. It exists to match a specific marketplace/search intent, then delegates execution to the canonical SkillFM Beacon MCP and local runtime.

Powered by SkillFM Beacon.

Quick Start

Use this gateway as an MCP stdio server:

npx -y @skillfm/llm-cost-optimizer-mcp@latest

Equivalent explicit SkillFM entrypoint:

npx -y @skillfm/mcp@latest

For MCP clients that accept JSON config:

{
  "mcpServers": {
    "llm-cost-optimizer": {
      "command": "npx",
      "args": ["-y", "@skillfm/llm-cost-optimizer-mcp@latest"]
    }
  }
}

What This Gateway Helps With

• Turn LLM spend questions into SkillFM Beacon usage and health checks.

• Guide users from rough token visibility to provider-level BYOK monitoring when they are ready.

• Surface cost-saving opportunities in context, model choice, cache use, batching, and repeated work.

• Keep the public package thin while delegating execution to the SkillFM local runtime.

This gateway is for users who ask:

• "How do I reduce OpenAI or Anthropic spend?"

• "Which agent workflow is burning tokens?"

• "Can I optimize LLM cost without sending keys to a SaaS dashboard?"

• "How do I connect provider usage after I trust the local checkup?"

How It Works

The public package is intentionally thin. It sets SKILLFM_GATEWAY_SOURCE=llm-cost-optimizer and forwards execution to @skillfm/mcp@latest, which then delegates to the canonical @skillfm/local runtime.

No private SkillFM platform logic, customer data, provider credentials, or backend modules live in this repository.

Activation Path

Start the local sidecar when the user wants to connect SkillFM:

npx -y @skillfm/llm-cost-optimizer-mcp@latest start

Agent-driven activation flow:

1. Read the sidecar URL from stdout or ~/.skillfm/local.json.

2. Call POST <sidecar_url>/activate/start.

3. Show the returned verification URL and real device code to the user.

4. Poll POST <sidecar_url>/activate/poll until it returns activated: true.

5. Use SkillFM Beacon MCP tools for checkups, usage visibility, BYOK guidance, and cleanup audits.

Do not fabricate a placeholder code. The device code must come from POST /activate/start.

Security Model

• Transparent gateway: This package is a public search/distribution gateway, not a separate hidden product.

• Local-first runtime: Runtime execution goes through SkillFM's local package.

• BYOK boundary: Provider keys are introduced only after user value is established, and key values are not read back by agents.

• No private core: This repository contains distribution metadata, docs, and a thin launcher only.

• Read-only first: Cleanup and usage inspection begin with read-only audits.
