Top picks

01

Managed integrations and MCP gateway that gives AI agents authenticated tool access.

Composio is one of the more mature managed-integration layers for agents, and its OAuth/multi-tenant auth handling genuinely removes painful glue code. The breadth of connectors and framework support is a real strength. The big caveat is pricing: the 2026 shift to usage-based billing produced steep cost jumps at production scale, so model your tool-call volume before adopting. As with everything in MCP, connectors and pricing move fast, so verify current terms with the vendor.

02

The Docker Hub of MCP: discover, install, and host thousands of MCP servers.

Smithery is arguably the closest thing to a Docker Hub for MCP, and its combination of a big registry plus one-click hosted endpoints is genuinely useful for skipping local setup. The CLI and OAuth handling for hosted servers are nice touches. Caveats: server quality varies widely across the long tail, hosted execution costs apply beyond browsing, and the registry landscape (Smithery, Glama, PulseMCP, the official registry) is still shaking out. Verify hosting limits and pricing with the vendor.

03

MCP server registry, in-browser inspector, and gateway with an LLM API bundled in.

Glama is a strong all-in-one: a big registry, a genuinely handy in-browser MCP Inspector, a gateway for access control and logging, plus a bundled multi-provider LLM API. The free open-source hosting is a nice draw for server authors. Caveats: self-reported scale numbers are large and hard to independently verify, the per-server-instance hosting model differs from per-call pricing so cost predictability depends on your setup, and, like all MCP registries, the space is crowded and fast-moving. Verify current plans with the vendor.
