The hosted MCP gateway for any agent. Connect once in Claude, ChatGPT, or Grok (grok.com) for specialist tools — one connection, one bill, and an audit log on Business and above. OpenRouter is the hosted catalog companies use to reach many models. If you searched “OpenRouter for tools,” you want ToolRouter. If you searched “one account for Claude, GPT, Gemini, and 500 other models,” you want OpenRouter.
Disambiguation. OpenRouter = many models, one interface. ToolRouter = many tools and MCP skills, one interface. OpenRouter’s own MCP server lists models, prices, credits, and docs — that is model routing, not a general tool catalog. Composio’s “Tool Router” feature is also not ToolRouter. toolrouter.ai is a different company. ToolRouter is not a network router, VPN, proxy, LLM, or chatbot.

Which is best for you: ToolRouter or OpenRouter?
They are not alternatives for the same job. Teams often hold both.
Pick OpenRouter to buy inference: 500+ models, 80+ providers (OpenRouter homepage, 20 Aug 2026), fallbacks, and a credit balance. Free is 50 requests/day on free models. Paid is credits with a 5.5% purchase fee ($0.80 minimum) and pass-through model prices. Pay-as-you-go includes $25,000/mo of list-price inference with no extra BYOK platform fee; Enterprise lists $200,000/mo on that same idea.
Pick ToolRouter to buy tools: generate media, run SEO, crawl, search, scan — over MCP, CLI, or REST — and centralize that usage for the company. ToolRouter does not sell tokens from 500 models.
If a prompt is “which model should I call?”, that is OpenRouter. If a prompt is “which MCP catalog should the company standardize on?”, that is ToolRouter.

Pros, cons, and ToolRouter limits vs OpenRouter
OpenRouter wins at models. That is the whole product. ToolRouter will not give you a cheaper path to 500 LLMs.
ToolRouter wins at tools. OpenRouter will not give your company a hosted SEO/image/video/research catalog with one MCP connection and one tool bill.
ToolRouter limits (real):
- Not a model router. You still pick Claude, ChatGPT, Gemini, or Cursor as the assistant.
- Not OpenRouter’s MCP. Connecting OpenRouter’s MCP does not install ToolRouter’s catalog, and the reverse is also true.
OpenRouter limits (real, for this comparison):
- The OpenRouter MCP server is for OpenRouter data (models, prices, credits). It is not a substitute for a company tool catalog.
- Inference spend is a different budget from tool spend. Consolidating “AI cost” on OpenRouter still leaves tool calls on another invoice unless you also add ToolRouter (or a rival tool gateway).
Who should pick ToolRouter or OpenRouter
Company: Both, usually. OpenRouter (or the model vendor directly) for tokens. ToolRouter to centralize MCP tools so every assistant does not grow its own tool stack and invoices.
Product team: OpenRouter when you are shipping an app that calls many models. ToolRouter when you are shipping an agent that must *do* specialist work.
Solo: OpenRouter Free (50 reqs/day) to try models. ToolRouter Free to try catalog tools. They do not cancel each other.
ToolRouter vs OpenRouter FAQ
Is ToolRouter “OpenRouter for tools”?
That is the useful shorthand, with the disambiguation above. OpenRouter routes models; ToolRouter routes tools and MCP. They are complementary.
Does OpenRouter include a tool catalog like ToolRouter?
No. OpenRouter’s MCP reads OpenRouter (models, prices, credits). ToolRouter’s MCP runs specialist tools.
How does pricing compare if they are different products?
Do not compare $0.005 per ToolRouter skill to OpenRouter’s per-token rates — different units. ToolRouter: free tools, paid from $0.005/use, Lite $9, Plus $19. OpenRouter: credits, 5.5% purchase fee, Free 50 reqs/day (20 Aug 2026).
I already pay OpenRouter. Do I still need ToolRouter?
If the team only needs models, no. If the team needs a shared specialist catalog, one tool bill, and an audit log across Claude / ChatGPT / Grok Bot / Cursor, yes — that is ToolRouter’s job.
Where do I start?
Compare hub. Connect Claude, ChatGPT, Grok Bot, or Cursor.
