Free MCP Server for AI Agents

Open-source · zero-dependency · pay-per-use AI API marketplace

Most MCP servers pile on third-party dependencies that break on install. AIMALL's MCP server uses only the Python standard library — clone it, set a key, run python3 server.py. It wraps an entire AI API marketplace into 5 standard tools any MCP client (Claude, Cursor, LangChain, Dify, Coze) can load in one click.

What your agent gets

• One endpoint, one key, one bill. Models, image, TTS, web search, medical data — all via /api/v1/ai/request with X-API-Key.
• Pay-per-use. No subscriptions. Estimate cost first with ai_estimate, then execute with ai_request.
• Self-serve onboarding. bootstrap_account registers + creates an agent key in one call. $1 free trial, +$4 after email verify.
• Verifiable trust layer. Live telemetry per asset (success rate, p95 latency), signed outcome records, ERC-8004 agent cards.
• Download accelerator. A lightweight GET endpoint accelerates GitHub / Gitee / GitLab pulls (free 5 GB/mo).
