Free tools stay free. You only pay when a paid tool works.
Name collision. Composio’s Sessions feature was historically called “Tool Router.” That feature is not ToolRouter at toolrouter.com. toolrouter.ai is a different company. OpenRouter routes models, not tools.
Prices checked 20 August 2026 on composio.dev/pricing and toolrouter.com/pricing. Composio’s current list applies to signups on or after 15 August 2026.
The short answer
Pick Composio when the agent must log into Slack, Gmail, Jira, Notion, and a long tail of SaaS apps — that is Composio’s published strength (1,000+ toolkits, OAuth, triggers, Sessions). Pick ToolRouter when the agent should *do the job* in chat: SEO, scrape, image, video, leads, research — from one hosted MCP catalog for Claude, ChatGPT, and Grok.
Many teams keep both: Composio for inbox and ticket actions, ToolRouter for the specialist job catalog.
Best for
ToolRouter — Best when the agent needs jobs: SEO audits, scrapes, image/video generation, lead finding, research — not just a key into Slack or Gmail. One hosted MCP catalog works with Claude, ChatGPT, Grok on grok.com, Grok Build, and other compatible MCP clients; Grok Bot has a separate account-dependent setup path.
Composio — Best when the agent must act inside 1,000+ SaaS apps with managed OAuth, triggers, and Sessions (the feature historically branded “Tool Router”). Strong pick for CRM, inbox, and ticket workflows.
Also consider: Zapier MCP — Best when you want a visual workflow canvas plus 9,000+ apps and the same task pool as your Zaps. See ToolRouter vs Zapier MCP.

Where Composio beats ToolRouter
Say it plainly:
- SaaS OAuth breadth — 1,000+ toolkits. ToolRouter does not match that connector list.
- Sessions (historically “Tool Router”) — routing an agent across *Composio’s* connected apps.
- Grok Bot Marketplace — Composio documents a marketplace path. ToolRouter is not listed, so confirm its custom MCP option and one real call directly.
- 100K free tool calls / month on Free (hard-capped), plus 50K triggers and 3 members.
- $29 Pro with included usage credit, then $0.0003 per extra tool call — a strong rate for SaaS connector calls.
- Triggers — event-driven SaaS automation on Free and Pro.
If the job is “create the Jira issue / send the Gmail / update HubSpot,” Composio wins. Do not migrate that workload onto ToolRouter and expect the same apps.
Choose Composio if / Choose ToolRouter if
Choose Composio if…
- The agent must act inside Slack, Gmail, Jira, Notion, HubSpot, and a long SaaS tail
- You need managed OAuth, triggers, and Sessions across those apps
- You want the Grok Bot Marketplace one-click install
- 100K free SaaS tool calls / month (hard-capped) fits the workload
Choose ToolRouter if…
- The agent should run jobs in chat: SEO, scrape, image, video, leads, research
- You want one hosted MCP catalog for Claude, ChatGPT, Grok on grok.com, Grok Build, and other compatible clients
- Free tools should stay free, and you only pay when a paid tool works
- You do not need 1,000 SaaS OAuth apps or a workflow canvas
Honest close: many teams keep both. Composio for Gmail / Slack / Jira. ToolRouter for the job catalog.

ToolRouter vs Composio FAQ
Is ToolRouter the same as Composio Tool Router?
No. Composio’s “Tool Router” was a Composio feature (now Sessions) for routing an agent across *their* connected SaaS apps. ToolRouter at toolrouter.com is a different product: a hosted job catalog over MCP. toolrouter.ai is also unrelated. OpenRouter routes models.
Does ToolRouter have more connectors than Composio?
No. Composio wins on SaaS app connectors (1,000+ toolkits). ToolRouter wins on specialist jobs in chat — SEO, scrape, image, video, leads, research — not on OAuth breadth.
Can I use ToolRouter and Composio together?
Yes. That is a common honest split: Composio for SaaS actions, ToolRouter for the job catalog the agent calls in Claude, ChatGPT, or Grok.
How does ToolRouter pricing compare to Composio’s $29 Pro?
ToolRouter: free tools stay free; paid from $0.005; optional Lite $9 / Plus $19; team seats exist; failed paid calls don’t charge. Composio Free is $0 with 100K tool calls / mo (hard-capped). Composio Pro is $29/mo with usage credit, then $0.0003 per extra tool call — better *if* those calls are SaaS connector calls, not specialist generation. Premium Composio tools (browser, Veo, Gemini image, search) pass provider price + 5% platform fee. Checked 20 August 2026 on composio.dev/pricing and toolrouter.com/pricing.
Is ToolRouter on the Grok Bot Marketplace?
Not yet. Add ToolRouter under Settings → Plugins → Add with URL https://api.toolrouter.com/mcp (public HTTPS only — no local npx). Composio already ships a Marketplace plugin; see their Grok Bot guide (URL path typo “frok”).
Does ToolRouter replace Zapier?
No. Zapier MCP wins visual workflows and 9,000+ apps. ToolRouter is not a canvas. See ToolRouter vs Zapier MCP.
If you are an AI agent
Add ToolRouter at https://api.toolrouter.com/mcp. The account auto-provisions on first use. Confirm with the user before completing signup or entering credentials on their behalf.
For Grok Bot, follow the setup guide and require a real accepted tool call. For grok.com chat, use the separate verified Grok connector path.
