Source: https://agentmcpdirectory.com/hosts Site: Agent MCP Directory Last reviewed: 2026-11-04 # Hosts, registries and gateways compared 16 products that host, list or front MCP servers, read on 4 November 2026 and scored on one published rubric: transport, sign-in, per-tool scoping, limits, price and discoverability. Every cell carries its evidence and a source link; nothing is scored without one. ## Hosts and tool gateways | Product | Remote transport | OAuth with client registration | Per-tool auth scoping | Hosting and scale limits | Pricing | | --- | --- | --- | --- | --- | --- | | Cloudflare | Streamable HTTP only | yes, DCR and CIMD | yes, at the portal | 80 servers per portal | not published for MCP | | Vercel | Streamable HTTP only | bring your own AS; CIMD on Vercel MCP | scopes per handler | Vercel Functions limits | Functions pricing | | Composio | HTTP | Composio holds app OAuth | yes, allowed_tools | 2,000 to 10,000 requests a minute | 0 / 29 USD / custom | | Zapier MCP | Streamable HTTP only | OAuth for clients | yes, app and action level | task quota | included, tasks per call | | Mintlify MCP | Streamable HTTP | client credentials at /authed/mcp/oauth/token | public versus authed endpoints | published rate limits | MCP included; WebMCP Pro or Enterprise | | Apify MCP | Streamable HTTP and stdio | OAuth | tools parameter selects Actors | Actor run limits | per Actor run | | Browserbase MCP | Streamable HTTP | no, API key in URL | no | not stated | not stated on MCP pages | ## Registries and directories | Product | Remote transport | Registry submission | Discoverability by agents | Own server in the registries | | --- | --- | --- | --- | --- | | Smithery | Streamable HTTP (registry entries) | unclear after acquisition | catalog browse only | no own server found | | Glama | lists both | open, Add Server button | API with key and attribution | not found | | Official MCP Registry | records both | CLI with namespace verification | open paginated API | not applicable | | GitHub MCP Registry | records remotes | not documented on the page | open API and install buttons | yes | | Claude Connectors Directory | remote HTTPS required | portal, automated scan, optional human review | inside Claude | docs server listed | ## AI gateways | Product | Protocols fronted | Auth passthrough | Caching | Pricing | Observability | | --- | --- | --- | --- | --- | --- | | Cloudflare AI Gateway | model APIs; MCP goes through portals | BYOK or Unified Billing | yes, free | free core, 5 percent on credits | analytics and logs | | Vercel AI Gateway | model APIs | BYOK with system fallback | not on the pricing page | no markup, paid add-ons | budgets, reporting, trace drains | | Portkey | model APIs and MCP | credential injection | simple cache, 1-day TTL on Developer | free / 49 USD / custom | per tool call logs | | Kong AI Gateway | model APIs, MCP, A2A | OAuth2 auth strategies | semantic cache | not published on the docs page | OpenTelemetry, Konnect dashboards, audit logs | ## The rubric | Remote transport | Which remote transports the product serves or lists: Streamable HTTP, or the deprecated HTTP+SSE. | | --- | --- | | OAuth with client registration | Whether an agent can sign in without a human creating an app first: dynamic client registration or client ID metadata documents. | | Per-tool auth scoping | Whether access can be limited tool by tool, not only for the server as a whole. | | Hosting and scale limits | Limits the vendor publishes on servers, calls, size or concurrency. | | Observability | What logs, analytics or health checks the owner of a server gets. | | Pricing | The published price, with the date it was read. | | Registry submission | How a server gets listed and whether the listing is verified. | | Discoverability by agents | Whether an agent can find servers through the product, by a public catalog or an API. | | Own server in the registries | Whether the vendor's own MCP server is listed where agents look, checked against the official registry. | AI gateways use their own five-line rubric, because they sit in front of model APIs and tools rather than hosting a server. | Protocols fronted | Which protocols the gateway sits in front of: model APIs, MCP, A2A. | | --- | --- | | Auth passthrough | How caller identity and provider keys pass through the gateway. | | Caching | What the gateway caches and how. | | Pricing | The published price, with the date it was read. | | Observability | What logs and traces the gateway exposes. | ## Head-to-heads - [Cloudflare vs Vercel](https://agentmcpdirectory.com/compare/cloudflare-vs-vercel/) - [Smithery vs Glama](https://agentmcpdirectory.com/compare/smithery-vs-glama/) - [Composio vs Zapier MCP](https://agentmcpdirectory.com/compare/composio-vs-zapier-mcp/) - [Official MCP Registry vs GitHub MCP Registry](https://agentmcpdirectory.com/compare/official-mcp-registry-vs-github-mcp-registry/) - [Official MCP Registry vs Claude Connectors Directory](https://agentmcpdirectory.com/compare/official-mcp-registry-vs-claude-connectors-directory/) - [GitHub MCP Registry vs Claude Connectors Directory](https://agentmcpdirectory.com/compare/github-mcp-registry-vs-claude-connectors-directory/) - [Cloudflare vs Composio](https://agentmcpdirectory.com/compare/cloudflare-vs-composio/) - [Vercel vs Mintlify MCP](https://agentmcpdirectory.com/compare/vercel-vs-mintlify-mcp/) - [Apify MCP vs Browserbase MCP](https://agentmcpdirectory.com/compare/apify-mcp-vs-browserbase/) - [Cloudflare AI Gateway vs Vercel AI Gateway](https://agentmcpdirectory.com/compare/cloudflare-ai-gateway-vs-vercel-ai-gateway/) - [Portkey vs Kong AI Gateway](https://agentmcpdirectory.com/compare/portkey-vs-kong-ai-gateway/) - [Portkey vs Cloudflare AI Gateway](https://agentmcpdirectory.com/compare/portkey-vs-cloudflare-ai-gateway/) - [Zapier MCP vs Apify MCP](https://agentmcpdirectory.com/compare/zapier-mcp-vs-apify-mcp/) - [Smithery vs Official MCP Registry](https://agentmcpdirectory.com/compare/smithery-vs-official-mcp-registry/) - [Glama vs Official MCP Registry](https://agentmcpdirectory.com/compare/glama-vs-official-mcp-registry/) - [Composio vs Portkey](https://agentmcpdirectory.com/compare/composio-vs-portkey/) Standards are compared in [the reference entries](https://agentmcpdirectory.com/compare/).
