Values you fill in

SOLANA_RPC_URL env
Solana mainnet RPC endpoint. Defaults to https://api.mainnet-beta.solana.com — bring your own (Helius / Quicknode / Triton) for production traffic.
ETH_RPC_URL env
Ethereum mainnet RPC for ENS resolution. Optional — falls back to ethers' default public providers.
HELIUS_API_KEY secret env
Optional Helius API key — enables exact supply + DAS data in pump_snapshot.
NVIDIA_API_KEY secret env
NVIDIA NIM key (nvapi-…) — leads the speak tool's TTS provider chain with the free Magpie TTS lane.
OPENAI_API_KEY secret env
OpenAI TTS — the speak tool's paid backstop when the free NVIDIA lane is unavailable.
REPLICATE_API_TOKEN secret env
Required for the generate_avatar tool (Replicate text/image-to-3D).
REPLICATE_TEXT_TO_AVATAR_MODEL env
Replicate version hash pinned for text-to-3D — recommended: latest tencent/hunyuan-3d-3.1.
SOLANA_SECRET_KEY secret env
Optional default base58 Solana secret for wallet_send / pump_buy. Per-call secret args override this. Treat like cash.
THREE_MINT env
Optional pump.fun mint address for $three so tools accept target="three" as shorthand.
MAX_SOL_PER_TX env
Per-transaction spend cap in SOL for the execution tools (wallet_send, pump_buy, pump_launch, pump_collect_fees).
REQUIRE_CONFIRM env
When on (default), execution tools refuse until re-issued with confirm:true. Set 0/false to disable the gate.

@three-ws/avatar-agent

An MCP server that turns any GLB into a 3D AI agent — inspect/validate/optimize models, then give one a Solana wallet, a voice, and pump.fun powers.

Install · Setup · Quick start · Tools · Requirements · three.ws

A single Model Context Protocol server that is two things at once. It is a general-purpose 3D toolkit — inspect_glb, validate_glb, optimize_glb, thumbnail_glb, and viewer_url work on any GLB/glTF model, no avatar required, powered by @gltf-transform/core and Khronos's official gltf-validator. It is also a 3D AI agent in a box — spawn a textured GLB avatar, give it a voice (OpenAI TTS), hand it a Solana wallet, and run pump.fun operations (Jupiter swaps, atomic Jito-bundled launches, creator-fee collection). Built and maintained by three.ws. Registry name: io.github.nirholas/3D-AI-Agent-Avatar.

For a lightweight, read-only avatar viewer (no wallet, no signing), see the sibling package @three-ws/avatar-mcp, which renders a live, rotatable on-chain avatar inline in the chat.

Install

npm install @three-ws/avatar-agent

Run it directly with npx (no install needed) or install globally for the CLI:

npx -y @three-ws/avatar-agent          # MCP stdio server

npm install -g @three-ws/avatar-agent # exposes three-avatar-agent

Setup

Add the server to your MCP client. Claude Code, one line:

claude mcp add avatar-agent -- npx -y @three-ws/avatar-agent

Claude Desktop / Cursor (JSON config):

"mcpServers": { "avatar-agent": { "command": "npx", "args": ["-y", "@three-ws/avatar-agent"], "env": { "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com", "OPENAI_API_KEY": "sk-...", "REPLICATE_API_TOKEN": "r8_..." } } } }

The 3D tools (inspect_glb, validate_glb, optimize_glb, thumbnail_glb, viewer_url) and pump_snapshot work with no environment variables. Voice, generation, and signing tools need the keys in Requirements. Restart your client after editing the config.

Inspect the full tool surface in a GUI:

npx -y @modelcontextprotocol/inspector npx -y @three-ws/avatar-agent

Quick start

Once connected, ask your client in plain language:

Inspect https://three.ws/avatars/cz.glb — how many triangles? Then validate it against the Khronos spec and optimize it with Draco.

Runs inspect_glb → validate_glb → optimize_glb({ draco: true }), returning the rewritten GLB inline with honest before/after sizes. Note that cz.glb already ships EXT_meshopt_compression + WebP textures, so re-encoding it with Draco reports a negative savedBytes: the pipeline never hides that, and an uncompressed source is where the wins actually are.

Spawn the cz avatar, give him shades, mint him a three-prefixed Solana wallet, pull a snapshot of $THREE, and have him say "we're so back."

Runs spawn_avatar → dress_avatar → wallet_create({ vanityPrefix: "three" }) → pump_snapshot → speak.

Tools

All 24 tools are free MCP tools: there is no per-call x402 charge. Tools marked execution sign and broadcast real Solana transactions that move real funds; configure your client's tool-approval flow for them.

Every tool ships MCP tool annotations: reads advertise readOnlyHint: true, and the four execution tools (wallet_send, pump_buy, pump_launch, pump_collect_fees) are flagged destructiveHint: true, so annotation-aware MCP clients prompt for confirmation before running them. The hints are advisory — the server-side REQUIRE_CONFIRM gate and spend caps (see Safety) apply regardless of client.

3D toolkit — works on any GLB, no avatar required

Tool	What it does
`inspect_glb`	Mesh / material / texture / animation / skin breakdown, bounding box, vertex and triangle counts. `@gltf-transform/core`.
`validate_glb`	Runs Khronos's official `gltf-validator`; returns errors, warnings, infos, hints with JSON pointers.
`optimize_glb`	Dedup → prune → weld → optional Draco. Returns the rewritten bytes inline with before/after sizes and a signed `savedBytes` (negative when re-encoding an already-compressed model costs more than it saves). Draco- and meshopt-compressed inputs are decoded on read, so a compressed avatar works like any other.
`thumbnail_glb`	Renders any GLB to a PNG via three.ws's hosted three-light rig + auto-framing camera. Returns base64 PNG inline.
`viewer_url`	Builds a `three.ws/viewer?...` URL + paste-ready iframe for any GLB or avatar session (background, auto-rotate, camera preset or explicit orbit, AR mode, dimensions).

Avatar

Tool	What it does
`list_avatars`	Catalog of default GLB avatars (`default`, `cz`), accessories, and pose presets.
`list_animations`	Live fetch of three.ws's pose presets (T-pose, wave, thinker, jump, dance, warrior2, …) grouped by category.
`spawn_avatar`	Creates an avatar session from a preset or custom GLB URL. Returns a `sessionId`.
`dress_avatar`	Applies accessories + a pose to a session.
`render_avatar`	Renders a posed avatar to a PNG — pose preset + camera orbit (theta/phi/radius) + ARKit-52 facial expression.
`generate_avatar`	Text/image-to-3D via Replicate (Hunyuan-3D). New session preloaded with the generated GLB.

Voice

Tool	What it does
`speak`	Synthesizes speech in the avatar's voice — free NVIDIA Magpie TTS lane first (`NVIDIA_API_KEY`), OpenAI TTS backstop (`OPENAI_API_KEY`). Returns base64 audio the client plays.

Wallet

Tool	What it does
`wallet_create`	Generates a Solana keypair. Optional vanity grinder (`vanityPrefix: "three"`). Secret is returned once.
`wallet_balance`	Reads SOL + all SPL token balances (incl. Token-2022).
`wallet_send_preview`	Previews a `wallet_send`: sender, recipient, amount, network fee, balance before and after, and any rule that would refuse it. Signs nothing.
`wallet_send`	Sends SOL on mainnet. Execution.

pump.fun

Tool	What it does
`pump_snapshot`	Live market snapshot: USD price (Jupiter), 24h volume + DEX (Dexscreener), pump.fun metadata, top-holder distribution. Pass `target: "three"` for $THREE when `THREE_MINT` is set. Read-only, no signer.
`pump_buy_quote`	Quotes a `pump_buy` for the exact amount and slippage: SOL spent, expected and minimum tokens, price impact, route and fees. Signs nothing; pass its `quote_id` to `pump_buy`.
`pump_buy`	Jupiter swap, direct or Jito-bundled (funder→buyer transfer + swap atomic). Accepts any runtime mint. Execution.
`pump_launch_preview`	Previews a `pump_launch`: funder and creator addresses, rent, dev buy, bundle tip, the funder's total and any rule that would refuse it. Signs, uploads and mints nothing.
`pump_launch`	Atomic launch via Jito bundle: separate funder + creator wallets, both txs in the same block. Uploads metadata to pump.fun IPFS if no URI is supplied. Execution.
`pump_collect_preview`	Previews `pump_collect_fees`: the live fee vault balance, rent kept behind, the exact SOL that would reach the destination, and any rule that would refuse it. Signs nothing.
`pump_collect_fees`	Atomic collect: `collectCoinCreatorFee` + drain to a safe wallet in one tx inside a Jito bundle — resistant to a leaked creator key. Execution.

Identity

Tool	What it does
`ens_sns_resolve`	Resolves `.eth` (ENS) and `.sol` (SNS) names to addresses, with reverse + favorite-domain lookups. SNS is read straight from the SPL Name Service accounts on your `SOLANA_RPC_URL`, so it depends on no third-party name service.

How atomic pump.fun works

The pump_launch and pump_collect_fees tools wrap two patterns:

Launch — the create tx's payerKey is the creator wallet, so the on-chain creator field (which receiv
