Let Your Agent Call Any AI Tool in One Click

Let Your Agent Call Any AI Tool in One Click
A zero-dependency MCP server that lets any MCP-capable agent (Claude, Cursor, Dify, Coze, LangChain) plug into the Souyi AIMALL AI tool marketplace — models, search, image, voice, video — pay-as-you-go, with $5 free credit on signup.
The Problem: Agents Want AI Tools, but Integration Cost Kills Them
Every agent builder hits the same wall today:
Want to add "web search" or "image generation" to your agent? You have to sign up at each vendor, read docs, wire up SDKs, and manage separate API keys.
Every vendor bills differently; balances are scattered everywhere, so you can never tell how much a single agent task actually cost.
Switching models means code changes; switching vendors means rewriting the adapter layer.
Result: 80% of agent projects die before their first successful external AI call.
The Fix: Make AI Tools a "Plug-and-Play Standard Part"
Souyi AIMALL is an AI API marketplace built for agents. Models and tools are unified behind a single endpoint — /api/v1/ai/request — authenticated with one X-API-Key, metered per call, returning a unified order and balance.
To let agents discover and connect themselves, we shipped three machine-readable artifacts:
llms.txt — an LLM/crawler overview plus a 3-step self-serve onboarding guide;
openapi.json — the full OpenAPI 3.0.3 contract;
.well-known/agent.json — an A2A-style Agent Card.
On top of that, we open-sourced the official MCP Server: it wraps the marketplace into 5 standard MCP tools any MCP client can load in one click.
Zero Dependencies: Runs on Python 3.8+ Without pip install
Most MCP servers depend on a pile of third-party packages. Ours uses only the Python standard library (stdio + JSON-RPC). Clone it and run python3 server.py.
export AIMALL_API_KEY="ak_your_key" # from the "My Agents" page on souyi.net.cn
python3 server.py
Five Tools Covering the Whole Flow
Tool
Purpose
list_assets
List every AI asset (ID, type, unit price)
ai_estimate
Estimate a call's cost (no charge) — budget gate
ai_request
Run the call; returns result + order ID + balance
bootstrap_account
Self-serve signup + agent creation; fetches the key
get_onboarding
Returns onboarding steps and doc links
Typical workflow: list_assets → ai_estimate → approve → ai_request.

Restart Claude and it can "write code with MiniMax-M3", "generate an image", or "run a web search" — billed from the $5 free credit, no human approval needed. Snippets for Cursor, LangChain, Dify, Coze are in config-examples/.
Why This Matters
Discovery: llms.txt / openapi.json / agent.json let frameworks understand automatically what this platform does and how to call it.
Unification: one endpoint, one key, one bill — goodbye multi-vendor sprawl.
Zero friction: $5 on signup, self-serve top-up (planned) — truly unattended.
