Smithery

MCP registry, connection runtime, and credential layer for agents

Smithery helps developers discover, publish, and connect MCP servers. Its managed connection API and CLI handle OAuth, encrypted credentials, token refresh, namespaces, short-lived service tokens, direct MCP calls, and usage observability so the same tool connections can be reused across chat agents, background workers, and client applications.

When to use Smithery

Smithery is listed for Deployment, Data, Auth workflows. Smithery helps developers discover, publish, and connect MCP servers. Its managed connection API and CLI handle OAuth, encrypted credentials, token refresh, namespaces, short-lived service tokens, direct MCP calls, and usage observability so the same tool connections can be reused across chat agents, background workers, and client applications. Consider it when an agent needs this capability through a documented service boundary instead of custom infrastructure maintained inside the application.

In 4agent's task model, the product maps to web extraction, deployment, workflow automation, authentication and secrets. That makes it a candidate for workflows that research the web, manage memory and knowledge, build and deploy software, operate production agents.

Integration checklist

Access: confirm the api key authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
Client support: official or documented clients are listed for typescript.
Automation: OpenAPI is not currently recorded, MCP is listed as available, and CLI support is listed as available. Confirm each requirement in the provider's current documentation.
Operations: test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.

Sources and verification

Use these primary sources to verify current behavior before making an implementation or purchasing decision. Product capabilities, limits, and prices can change after a 4agent listing is reviewed.
