Alternatives to Self-Hosting MCP Servers
Every MCP server starts the same way. You find a GitHub repo, clone it, install dependencies, configure environment variables, and run it. Maybe you wrap it in a Docker container. Maybe you set up a systemd service. Either way, it works.
Then you need a second server. And a third. Now you have three repos to keep updated, three sets of API keys to manage, three processes to monitor. Version updates mean pulling changes and hoping nothing breaks. If an upstream API changes its auth flow, you fix it yourself.
Self-hosting one MCP server is fine. Self-hosting five is a part-time job.
Here are the managed alternatives.
AgentPatch
AgentPatch is a hosted tool marketplace. You get one API key, one connection, and access to 50+ tools. Google search, Bing search, web scraping, image generation, email, Google Maps, YouTube transcripts, stock data, and more.
Every tool is available through three protocols: MCP, REST API, and CLI. Your agent connects once and discovers all available tools. No containers to run, no repos to clone.
Pricing uses credits. One credit is $0.0001 USD. Each tool lists its price per call. You pay for what you use with no monthly minimum. Failed calls get refunded.
The API responses are optimized for LLM context windows. Tool outputs are structured and compressed so your agent burns fewer tokens processing results. This adds up when an agent chains five or six tool calls in a single conversation.
Toolhouse
Toolhouse provides managed MCP hosting with an SDK-centric approach. You install their Python or TypeScript SDK, connect it to your agent framework, and call tools through a clean programmatic interface.
The focus is on making the MCP transport layer invisible. You do not think about connections, handshakes, or message formatting. The SDK handles it.
Toolhouse offers a free tier with paid plans for higher usage. The tool catalog covers common agent needs: web browsing, code execution, and data retrieval.
Composio
Composio hosts 500+ integrations as pre-built agent tools. The scale of the catalog is the main draw. If your agent needs to interact with Salesforce, Jira, Slack, Google Workspace, GitHub, or dozens of other SaaS products, Composio probably has a pre-built action for it.
Auth is handled per integration. Composio manages OAuth flows, token refresh, and credential storage for each connected service. This matters for enterprise use cases where agents act on behalf of users with their own accounts.
Composio provides SDKs for major agent frameworks: LangChain, CrewAI, OpenAI function calling. The integrations plug into your existing agent architecture.
Pricing is enterprise-oriented with a free tier for smaller projects.
Smithery
Smithery is an MCP server registry with some hosted options. It catalogs community-built MCP servers and provides a directory for discovering them.
The registry model is different from the other options here. Smithery does not rebuild tools from scratch. It indexes existing MCP servers and, for some, offers a hosted version so you do not have to run them yourself.
This is useful for discovery. If you want to find an MCP server for a specific API, Smithery’s catalog is a good starting point. The hosted option removes some self-hosting friction, though the depth of managed infrastructure is lighter than purpose-built platforms.
Comparison
| Feature | AgentPatch | Toolhouse | Composio | Smithery |
|---|---|---|---|---|
| Protocol | MCP + REST + CLI | MCP (SDK) | SDK-based | MCP |
| Tool count | 50+ | Growing | 500+ | Registry (varies) |
| Auth handling | Built-in | Built-in | Per-user OAuth | Depends on server |
| Pricing | Per-call credits | Tiered plans | Free + enterprise | Free registry |
| Response optimization | LLM-optimized | Standard | Standard | Standard |
| Self-host option | No | No | Yes (open source) | Yes (registry) |
The hybrid approach
You do not have to pick one strategy. The practical path for most teams is a mix.
Use managed services for commodity tools. Web search, image generation, email sending, maps lookups. These are well-defined, stable APIs that someone else can host better than you can. Let a managed platform handle the uptime, the API key rotation, and the version updates.
Self-host for custom and internal tools. Your company’s internal database, your proprietary scoring model, your custom CRM integration. These tools contain business logic that no marketplace will offer. Run them yourself.
This split keeps your maintenance burden focused on the tools that actually contain your competitive advantage. Everything else is a managed dependency.
A typical setup might look like this: AgentPatch or Toolhouse for external data tools (search, scraping, public APIs), plus one or two self-hosted MCP servers for internal systems. Your agent connects to both. MCP supports multiple server connections natively, so this is not a hack. It is the intended architecture.
Wrapping up
Self-hosting MCP servers made sense when the ecosystem was young and managed options did not exist. That has changed. Multiple platforms now host tools with proper uptime, auth management, and usage tracking.
The question is not whether to use managed MCP tools. It is which ones to manage yourself and which ones to hand off. Keep the custom stuff close. Let someone else run the commodity tools.
Your agent does not care where the tools live. It cares that they work.
