SkillFM Claude Code Token Usage MCP

Claude Code token usage and cost 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/claude-code-token-usage-mcp@latest

Equivalent explicit SkillFM entrypoint:

npx -y @skillfm/mcp@latest

For MCP clients that accept JSON config:

{
  "mcpServers": {
    "claude-code-token-usage": {
      "command": "npx",
      "args": ["-y", "@skillfm/claude-code-token-usage-mcp@latest"]
    }
  }
}

What This Gateway Helps With

• Inspect Claude Code token usage and estimated cost signals.

• Connect usage visibility to SkillFM Beacon AI health checks.

• Find repeated context, stale sessions, and cost-saving opportunities.

• Route users toward local-first SkillFM activation without asking for provider keys first.

This gateway is for users who ask:

• "How many Claude Code tokens did I use today?"

• "Why did my Claude Code usage spike?"

• "Which sessions or projects are wasting context?"

• "Can my agent show me token usage before I connect provider keys?"

How It Works

The public package is intentionally thin. It sets SKILLFM_GATEWAY_SOURCE=claude-code-token-usage 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/claude-code-token-usage-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.
