ToolRouter is the OpenRouter for tools. Where OpenRouter gives you every model behind one API, ToolRouter gives every AI agent one MCP connection to a hosted catalog of 250+ specialist tools and 1,300+ skills, maintained and billed centrally.
Several products aim at that same shape. This page puts the honest ones side by side. Every rival figure below is quoted from that company's own live public page, checked on 4 September 2026. Where a company does not publish a number, the cell says so rather than guessing.
Name collision. toolrouter.ai and toolroute.ai are different companies from ToolRouter at toolrouter.com. Composio's Sessions feature was historically branded "Tool Router" and is not ToolRouter. OpenRouter routes models, not tools.

Checked on 4 September 2026 at monid.ai and docs.monid.ai, toolroute.ai, composio.dev and composio.dev/pricing, and arcade.dev and arcade.dev/pricing. ToolRouter figures from toolrouter.com/pricing.
Do not read the price row as like-for-like. A ToolRouter paid call, a Monid call, a ToolRoute request, a Composio tool call and an Arcade auth event are five different units of work. Compare what one finished job costs on each, not the headline per-unit number.
What we left out
Facts we could not verify on a live public page today are absent rather than estimated:
- Monid's tool count on its own documentation site — the docs say only "The catalog grows every single day."
- Whether Monid describes itself as "OpenRouter for agent tools" on its own site — that phrasing appears in third-party coverage, not on monid.ai.
- Arcade's tool or integration count — not stated on the pricing page.
- Any claim about uptime, latency, model quality, or funding for any company on this list.
How to choose
Pick ToolRouter when the agent should do specialist jobs in chat — SEO audits, scraping, image and video generation, research, live web data — from one hosted MCP catalog that works with Claude, ChatGPT, Cursor, VS Code, Gemini CLI, Grok and Windsurf, with free tools that run before you claim an account.
Pick Monid when you want the largest stated count of tools and APIs behind one per-call balance.
Pick ToolRoute.ai when a fixed monthly request quota suits your usage better than per-call billing.
Pick Composio when the agent must log into a long tail of SaaS apps with managed OAuth and triggers. See ToolRouter vs Composio.
Pick Arcade when each end user must authorize their own accounts and you need a per-user auth runtime, or when you need VPC or air-gapped deployment. See ToolRouter vs Arcade.
