How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
A JSON-RPC 2.0 response containing a result object with content array; each content item has a text field with a JSON string including ok status, warnings array, and meta object (e.g. vertex count). Tool output varies by tool called — search returns listings, reputation returns scores, registration returns on-chain confirmation.
Example use cases
Example prompt
“Use three.ws to validate my 3D avatar model with ID 'avatar_42' — call tools/call with validate_model and tell me if there are any warnings or vertex issues.”
Technical details
Endpoint
POSThttps://three.ws/api/mcpWhen to prefer
Choose this endpoint when you need programmatic access to three.ws 3D avatar tooling via the MCP protocol — especially for validating or optimizing 3D models, searching the public avatar directory, or interacting with Solana-based identity and reputation for avatar agents. Prefer this over the REST or embed-tag interface when automating agent workflows or integrating 3D avatar capabilities into an AI agent pipeline.
Side effects
- Invalid MCP method name returns JSON-RPC error
- Missing jsonrpc '2.0' constant causes request rejection
- Unknown tool name in tools/call params returns tool-not-found error
- Malformed params object for a tool returns validation error
- Payment not attached (x402) results in 402 Payment Required before processing
- Solana registration fails if wallet address is invalid or network is congested
