Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

generate_avatar_from_image

PAID (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).]

Argument	Type	Description
prompt	string	Optional style/subject hint alongside the image
platform	string	Target engine (adds rigging + engine export)
image_b64*	string	Base64-encoded reference image (PNG/JPEG)
asset_kind	string	Asset taxonomy
polygon_tier	string	Quality tier (defaults to the platform's configured tier)
texture_size	number	Texture bake size in px (defaults per platform, else 2048)
idempotency_key	string	Optional caller-chosen dedup key (<=200 chars, [A-Za-z0-9_.:-]). Replaying the same key (per payer) returns the original job_id — no new GPU job, no new charge. Use on any retry after a timeout/5xx.

generate_avatar_from_text

PAID (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).]

Argument	Type	Description
prompt*	string	What to generate (subject description)
platform	string	Target engine (adds rigging + engine export)
asset_kind	string	Asset taxonomy
polygon_tier	string	Quality tier (defaults to the platform's configured tier)
texture_size	number	Texture bake size in px (defaults per platform, else 2048)
idempotency_key	string	Optional caller-chosen dedup key (<=200 chars, [A-Za-z0-9_.:-]). Replaying the same key (per payer) returns the original job_id — no new GPU job, no new charge. Use on any retry after a timeout/5xx.

get_generation_status

FREE: 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.]

read-only

Argument	Type	Description
payer	string	x402 payer address the original generate call used — required when looking up by idempotency_key (scopes the key to its owner).
job_id	string	Job id returned by a generate tool
idempotency_key	string	Alternate lookup key: the idempotency_key passed to the original generate call. Requires payer.

  }
}

post_process_mesh

Post-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.]

read-only

Argument	Type	Description
mesh_url	string	HTTPS URL to fetch the raw GLB from instead of inline base64 (e.g. a presigned storage URL) — the host must be on this server's configured allowlist (off by default). Provide exactly one of glb_base64 or mesh_url.
platform	string	Target engine platform (adds export validation)
asset_kind	string	Asset kind (skinning auto-on for avatar only)
glb_base64	string	Base64-encoded raw binary GLB to post-process. Provide exactly one of glb_base64 or mesh_url.
polygon_tier	string	Decimation tier for the output mesh

repair_mesh

Repair 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.]
