Comparison
Smithery vs Composio
Smithery and Composio both land on Depends.
Composio
Depends
Confidence: Medium
Buy if your dev team is wiring AI agents into many low-risk SaaS apps and can tolerate usage-based pricing.
| Compare | Smithery | Composio |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Developers wiring AI agents to tools | Dev teams building AI agents |
| Who it's not for | Non-technical teams . useless without a developer | Anything touching sensitive customer data |
| Privacy | One critical path-traversal flaw, fixed October 2025, exposed ~3,000 hosted MCP servers; third-party server quality is largely unvetted.⁴ | Poor track record: four 2024 SDK CVEs and a May 2026 breach where one OAuth token exposed ~10,000 accounts. |
| Support quality | No evidence either way | Invested in end-to-end support stack per Decimal case study |
| Public sentiment | Reddit chatter is mixed: developers like the breadth but repeatedly question trust, reliability, and how the hosting is funded.⁹ | Developers like the one-stop breadth of integrations for agents, but a vocal group questions whether direct APIs or self-hosted options fit better. |
| Biggest gotcha | Third-party servers carry supply-chain risk; vet before connecting production credentials⁵ | One OAuth token exposed ~10,000 accounts in May 2026 . audit token scoping before production |
