    How to connect

    How to connect AXIS Avatar Foundry to Claude

    The server address to paste into Claude settings:

    https://api.avatar.jonathanarvay.com/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect AXIS Avatar Foundry to ChatGPT

    The server address to paste into ChatGPT settings:

    https://api.avatar.jonathanarvay.com/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    How to connect AXIS Avatar Foundry to Cursor

    The server address to paste into Cursor settings:

    https://api.avatar.jonathanarvay.com/mcp

    Fastest: click Open in Cursor below and confirm the prompt.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    If the service needs sign-in, an authorize button appears next to the server in the MCP list.

    Raw names from tools/list. Only developers need these.

    axis_list_capabilitiesList all AXIS Foundry capabilities (input formats, export platforms, validation rules). [Free — no payment required.]
    axis_validateValidate an avatar mesh file. Returns pass/warn/fail counts and detailed rule results. [Paid: $0.25 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    axis_inspectInspect an avatar's contract state and provenance chain (stage, bone/vertex counts, provenance step count, chain_valid + any broken links). Does not return a quality grade — use axis_validate for pass/warn/fail rule results. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    axis_compareCompare two avatar contracts. Returns similarity score and section-level diffs. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    axis_processRun the full AXIS avatar pipeline (classify → normalize → rig → skin → validate). Returns contract summary. [Paid: $1.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    post_process_meshPost-process a RAW generated mesh (normalize → mesh-repair → rig/skin → validate → export) and return the finished, validated GLB as base64. The inline counterpart of axis_process (which needs a server file path) — the generation post-process step, callable by an LLM/agent that holds the mesh bytes (e.g. fresh TRELLIS output) or a URL to them. Provide the mesh EXACTLY one of two ways: inline as base64 (glb_base64) or as an HTTPS URL (mesh_url) — the URL's host must be on this server's operator-configured allowlist (off by default; an unconfigured allowlist refuses every mesh_url call, it is never open to an arbitrary host). Providing both or neither is a real input error. [Paid: $1.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    axis_exportExport an avatar to a target engine platform with validation and HMAC-signed manifest. [Paid: $0.50 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    axis_manifest_verifyVerify an export manifest's integrity and optionally check content hash. [Paid: $0.10 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    repair_meshRepair a mesh into AXIS canonical frame (scale/axis/degenerates/normals) and return repair metrics. [Paid: $0.75 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    retarget_animationRetarget a built-in animation clip to a platform mapping and report coverage + deterministic hashes. [Paid: $0.75 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    roblox_compliance_checkRun Roblox R15 compliance checks against a mesh using canonical pipeline outputs. [Paid: $0.25 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; settled only on a successful (non-error) result.]
    generate_avatar_from_textPAID (x402, 5 USDC): generate a production 3D avatar from a text prompt — xAI concept image → TRELLIS.2 GPU mesh → full canonical post-process (repair/validate/export). Payment settles ONLY when generation completes; a failed generation is never charged. Returns a job_id — poll with the free get_generation_status tool (typical runtime 5-15 minutes). Pass idempotency_key when a retry is possible (timeout/5xx) — replaying the same key returns the original job_id instead of a second GPU job/charge. [Paid: $5.00 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; DEFERRED settlement — charged only when the generation job completes, a failed job is never charged. Poll get_generation_status (free).]
    generate_avatar_from_imagePAID (x402, 6 USDC): generate a production 3D avatar from a reference photo (base64) — xAI A-pose normalize → TRELLIS.2 GPU mesh → full canonical post-process. Payment settles ONLY when generation completes; a failed generation is never charged. Returns a job_id — poll with the free get_generation_status tool (typical runtime 5-15 minutes). Pass idempotency_key when a retry is possible (timeout/5xx) — replaying the same key returns the original job_id instead of a second GPU job/charge. [Paid: $6.00 USDC via x402 for unauthenticated calls on the hosted /mcp endpoint; DEFERRED settlement — charged only when the generation job completes, a failed job is never charged. Poll get_generation_status (free).]
    get_generation_statusFREE: poll a generation job submitted by the paid generate tools. Returns status/progress; once complete AND the deferred payment has settled, returns the download URLs. A failed generation reports charged=false. Look up by job_id, or by idempotency_key + payer if the job_id was lost. [Free — no payment required.]
