OpenRouter ChatGPT Plugin

Analytics, Cost Optimization & MCP Tools for ChatGPT and Codex.

An open-source OpenRouter plugin that combines OpenRouter's official MCP server with a private analytics bridge for account spend, usage analysis, model comparison, cost anomaly detection, and cost optimization.

Version status (2026-10-11): RouterLens personal operations 0.5.0, with a sanitized public Worker candidate and a separate legacy root application 0.3.0 Alpha.

Reviewed source snapshot

The standalone RouterLens Worker candidate adds request details, spend investigations, persistent reports, experiment comparisons, and versioned model presets with routing validation/export. The historical directory name remains; use its own install/build/test workflow.

Private source 00ade82f2876cf3d1f396046527c56bd110cb919 deployed successfully on 2026-10-11. Hosting success is distinct from live acceptance and scheduled notification delivery. Public identity and deployment placeholders remain unconfigured. No team version, paid inference or production model switch is included.

The official MCP handles capabilities OpenRouter already exposes well. RouterLens adds the private account-analysis layer.

Why two MCP servers?

Duplicating OpenRouter's official model and generation tools would create unnecessary maintenance. RouterLens focuses on the missing workflow layer:

• account analytics

• cost attribution

• cost anomalies

• cost optimization

• API-key usage visibility

• normalized model/provider comparisons

Self-hosting

Requirements:

• Node.js 20+

• Vercel or another Next.js-compatible host

• OpenRouter Management API Key

Environment variables:

OPENROUTER_MANAGEMENT_KEY=
MCP_AUTH_TOKEN=

Install and build:

npm install
npm run check

Run locally:

npm run dev

Endpoints:

• MCP: /api/mcp

• Health: /api/health

Security

• Management Keys are read from server environment variables.

• Secrets are never returned by MCP tools.

• API-key listing only exposes metadata and hashes returned by OpenRouter.

• V0.3 contains no key create/update/delete tools.

• The self-hosted MCP endpoint is protected by MCP_AUTH_TOKEN.

• Account data is queried from OpenRouter on demand and is not persisted by RouterLens.
