Per-Project Config

ainpc login --local --key YOUR_KEY --game my-rpg   # saves to .ainpc/config.json
ainpc login --key YOUR_KEY --game my-rpg           # saves to ~/.ainpc/config.json
ainpc config                                       # show active config

Local config overrides global. Add .ainpc/ to your .gitignore.

Agent Integration

Add to your CLAUDE.md, .cursorrules, .clinerules, or .windsurfrules:

Use the ainpc CLI for NPC management.
Config auto-loaded from .ainpc/config.json or AINPC_API_KEY env.
Run ainpc --help for full reference.

MCP Server

49 tools for AI agents: NPC CRUD, dialogue, game events, persona generation, studio account, usage and billing.

Local (stdio):

{ "mcpServers": { "ainpcengine": { "type": "stdio", "command": "ainpc", "args": ["mcp-serve"] } } }

Requires npm install -g ainpc-cli + ainpc login --key npk_YOUR_KEY --game my-rpg (or AINPC_API_KEY env).

Remote (SSE, zero install) — for Claude Web and other web-based agents:

{ "mcpServers": { "ainpcengine": { "type": "sse", "url": "https://mcp.ainpcengine.com/sse",
  "headers": { "Authorization": "Bearer npk_YOUR_API_KEY" } } } }

No key yet? Connect keyless — the remote server starts in onboarding mode and an agent can self-signup via the ainpc_signup tool.
