SageLib MCP Server

中文

SageLib AI 网关的远程 MCP 服务：一个网关调用 68 个国内外大模型（OpenAI、Anthropic、Gemini、Kimi、GLM、DeepSeek、Qwen、MiniMax、豆包…），人民币按量计费，支持 OpenAI / Anthropic / Gemini 三种原生协议。

端点：https://www.sagelib.com/mcp（Streamable HTTP，JSON-RPC 2.0）
官网：https://www.sagelib.com
文档：OpenAPI · llms.txt
鉴权：只读工具无需任何凭据；call_model 由调用方传入自己的 API Key（服务端不保存）

工具

工具	参数	返回
`list_models`	`app_type`（`text`/`image`/`audio`/`video`）、`keyword`、`limit`	在架模型的标识、名称、类型、上下文长度、输入/输出单价
`compare_models`	`codes`（2–6 个模型标识）	上下文长度与价格的横向对比
`call_model`	`model`、`prompt`、`api_key`、`max_tokens?`、`system?`	经网关调用模型的回答（服务端不存密钥）

价格为厂商公布的官网价（网关折后价登录后可见）；返回里带币种与计价单位（/百万 token、/张、/秒）。

在客户端里添加

PI：

{ "mcpServers": { "sagelib": { "url": "https://www.sagelib.com/mcp" } } }

Claude Desktop / 其他支持远程 MCP 的客户端：添加「远程 MCP」，URL 填 https://www.sagelib.com/mcp。

{ "mcpServers": { "sagelib": { "url": "https://www.sagelib.com/mcp" } } }

curl 复现

curl -s -X POST https://www.sagelib.com/mcp -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"compare_models","arguments":{"codes":["claude-sonnet-5-5","kimi-k3.1-pro"]}}}'

说明

托管式服务，无需安装；
list_models / compare_models 只返回公开目录数据；
call_model 会把请求转发到 https://www.sagelib.com/openai/chat/completions，密钥只用于本次请求。

Remote Model Context Protocol server for SageLib AI Gateway — one API gateway for 68 LLMs (OpenAI, Anthropic, Gemini, Kimi, GLM, DeepSeek, Qwen, MiniMax, Doubao…) with real-time CNY/USD pricing and OpenAI / Anthropic / Gemini native protocols.

Endpoint: https://www.sagelib.com/mcp (Streamable HTTP, JSON-RPC 2.0)
Website: https://www.sagelib.com
Docs: OpenAPI · llms.txt
Auth: read-only tools need no credentials; call_model takes the caller's own API key

Tools

Tool	Arguments	Returns
`list_models`	`app_type` (`text`/`image`/`audio`/`video`), `keyword`, `limit`	In-stock models with context length and input/output price
`compare_models`	`codes` (2–6 model ids)	Side-by-side context length and pricing
`call_model`	`model`, `prompt`, `api_key`, `max_tokens?`, `system?`	Model reply via the gateway (no keys stored)

Prices are the vendors' published official prices (discounted gateway price is shown after login); the response includes currency and billing unit (per MTok / per image / per second).

Add it to your client

PI:

{ "mcpServers": { "sagelib": { "url": "https://www.sagelib.com/mcp" } } }

Claude Desktop / any client supporting remote MCP: add a remote server with URL https://www.sagelib.com/mcp.

{ "mcpServers": { "sagelib": { "url": "https://www.sagelib.com/mcp" } } }

Try it

curl -s -X POST https://www.sagelib.com/mcp -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"compare_models","arguments":{"codes":["claude-sonnet-5-5","kimi-k3.1-pro"]}}}'

Notes

Hosted server; nothing to install.
list_models / compare_models return public catalogue data only.
call_model forwards to https://www.sagelib.com/openai/chat/completions with the key passed in the call.
