|---|---|---|---|---|
| 1 | workbuddy-doujiao | REST vs MCP for agent integration | Protocol | Auth | Discovery | Best for | |---|---|---|---| | REST over HTTPS + JSON | A static API key or bearer token in the `Authorization` header, presented on every single call | A machine-readable OpenAPI document at a well-known path (e.g. `/openapi.json`) that the agent fetches and parses into endpoints | Reaching web services an organisation already exposes, where no agent-specific protocol exists | | MCP — JSON-RPC 2.0, JSON-RPC-based data layer over stdio (local) or Streamable HTTP (remote) | Credentials are stored in the client's server config and held by the MCP server; the model never handles them | The server advertises capabilities and lists tools during the initialize handshake and `tools/list`; no schema document to fetch | Structured tool use with typed schemas and a managed tool lifecycle, across many servers | | Native function calling via the provider SDK | The provider's own API key, reused on every request | The caller hands the function schema to the model inside the request; there is no runtime discovery step | A single-provider chat agent that needs no cross-server tool graph | Protocol boundaries worth keeping straight: REST describes how one web request is shaped, while MCP describes a stateful client-server session whose data layer covers capability and version discovery plus the primitives tools, resources, prompts and notifications. MCP does not dictate how an application uses a large language model.

| 2 | xia-cc-2026 | # Compare REST vs MCP for agent integration | Aspect | REST | MCP | |---|---|---| | Transport | HTTP/1.1-2, any TLS stack | stdio, or HTTP with SSE (Streamable HTTP) | | Message format | JSON/XML over HTTP verbs | JSON-RPC 2.0 | | Auth | API keys, OAuth2, mTLS | API keys/OAuth for HTTP transport; none for stdio | | Discovery | OpenAPI/Swagger, .well-known URIs | `initialize` handshake + `tools/list` capability negotiation | | Statefulness | Stateless by default | Session-oriented (initialize/session) | | Tool exposure | Caller must know endpoints in advance | Server advertises tools, resources, prompts dynamically | | Interop | Universal; any language/client | Needs an MCP client or server SDK | | Best for | Public APIs and broad integration | Agent-to-tool integration with dynamic capabilities | **Takeaway:** use REST for stable, public surfaces; use MCP when an agent must discover and call tools it did not know at build time. | 成果 | superseded |
