Secret Handling

MCP client library for Python agents. Security depends on connected MCP servers. Validate server responses — prompt injection via tool results is a known attack vector.

Best When

You are building a new MCP server or agent application and want a batteries-included framework with inspector tooling, React widget support, and optional managed hosting.

Avoid When

You need a lightweight adapter for a single existing API; the framework overhead is unnecessary for simple integrations.

Use Cases

• Scaffolding and developing new MCP servers in TypeScript or Python with type-safe tool definitions
• Building interactive React UI widgets that render inside Claude, ChatGPT, and other MCP clients
• Deploying production MCP servers to Manufact cloud with observability and metrics

Not For

• Users who only want to consume existing MCP servers (this is for building them)
• Minimalist deployments that do not need UI widgets or cloud hosting
• Projects already using FastMCP or the official MCP SDK directly without needing the extra framework layer

Known Gotchas

⚠ This is a framework for building servers, not a pre-built integration; agents benefit indirectly.
⚠ Manufact cloud deployment vendor lock-in for production hosting.
⚠ MCP Apps (React widgets) require MCP clients that support UI rendering, which is not universally available.
⚠ Python and TypeScript SDKs may have feature parity gaps; verify capabilities in your target language.
