ECC × Itô Compute Integration

Status: Implemented local CLI bridge; managed inference remains unavailable

Owner: Affaan Mustafa

Updated: 2026-07-23

Thesis

The distribution chain remains provider-neutral:

GPU compute (Itô or another selected provider)
  -> any open-source model
  -> model harness
  -> ECC meta-harness

Itô is ECC's preferred compute sponsor, never an exclusive provider. Owned hardware, existing clusters, and other providers remain valid.

Implemented boundary

ECC delegates to the canonical Itô package in Ito-Markets/ito-cloud-runtime/cli/ito-compute-cli. ECC does not maintain a second API client or response schema.

The wrapper exposes only the canonical CLI's login, auth, find, status, and evals operations:

ecc ito login [--no-browser]
ecc ito auth
ecc ito find <all required RFQ constraints>
ecc ito status
ecc ito evals --cluster <id> --live-sixtytwo --nodes <list> --config-dir <dir>

The canonical MCP server exposes only ito_auth, ito_find, and ito_status. ECC includes an opt-in configuration template pointing to the local built MCP entry. It does not enable the server by default.

The former browser/manual-copy command is retired. ecc ito login delegates to the canonical CLI's device authorization, which opens the Itô verification page by default and persists a device token in macOS Keychain. --no-browser suppresses that page handoff. ECC itself performs no browser automation and stores no economic state. ecc ito auth is validation-only, never starts device login, and rejects --no-browser.

Local install

ito-compute-cli is unpublished. Install it from the canonical repository:

git clone https://github.com/Ito-Markets/ito-cloud-runtime.git
cd ito-cloud-runtime/cli/ito-compute-cli
npm ci
npm run check

Set ECC_ITO_CLI_EXECUTABLE to the explicit absolute built entry:

/absolute/path/to/ito-cloud-runtime/cli/ito-compute-cli/dist/bin/ito.js

ECC does not resolve the credential-bearing client through PATH; this avoids forwarding authentication material to an unrelated executable with the same name.

For MCP, configure node with:

/absolute/path/to/ito-cloud-runtime/cli/ito-compute-cli/dist/bin/ito-mcp.js

Device login forwards only required authorization settings, optional Itô endpoint overrides, and the minimum process environment; it never inherits ITO_API_KEY. The auth, find, and status commands forward ITO_API_KEY directly when configured; ITO_AUTH_MODE=legacy is not required. Device tokens use macOS Keychain by default. Explicit file fallback retains owner-only 0700 directory and 0600 token-file permissions. ECC does not inspect or log secrets.

Authority and economics

• login starts canonical device authorization, with --no-browser available when the operator does not want the CLI to open the verification page.
• auth validates existing credentials only.
• find reads live inventory and submits a live authenticated RFQ. An operator or agent must gather every hard topology/economic constraint and obtain explicit buyer authority before invoking it.
• status reads current RFQ and procurement status.
• evals requires both ITO_ENABLE_SIXTYTWO_LIVE=1 and --live-sixtytwo, then runs only the canonical CLI's pinned sixtytwo-cli==0.3.33 qualification adapter against an explicit node list and existing absolute configuration directory. It receives no ITO_API_KEY or unrelated cloud/model credentials and cannot rent, launch, recover, repair, reset, purchase, or order resources.
• ECC returns the canonical process's stdout, stderr, and exit code unchanged.
• An inventory row or RFQ is not a capacity reservation.
• Only a non-null canonical firm quote is firm.
• After an ambiguous transport error, check status before repeating find.
• Global ECC dry-run does not create a local success result; the wrapper fails closed without invoking the canonical CLI.

All durable RFQ, quote, procurement, and reservation state remains owned by the Itô platform. ECC adds no shadow store.

Unsupported in this slice

ECC exposes no quote lock, purchase, workload execution, or inference command. Node qualification is live-only through the separately gated canonical adapter; the ECC bridge does not expose its paper fixture mode.

Managed inference remains unavailable. ECC does not claim that Itô created a model endpoint, deployed a workload, reserved capacity, or moved funds.

Skill and install shape

skills/ito-compute/SKILL.md is an opt-in workflow installed through:

• module: ito-compute
• component: capability:ito-compute
• profile: full

The skill documents the exact CLI and MCP names and the approval boundary. It does not bundle the unpublished CLI.

Publication blocker

The integration works from a local build. Distribution remains blocked until ito-compute-cli has an approved package-publication policy and is published or replaced by another verified distribution channel. ECC must not claim npm availability before a registry read confirms it.

The ECC package version remains unchanged in this worktree. Its version bump, release commit, and publication are intentionally deferred to the release owner after review.

Verification

The local contract suite proves:

• only the four supported operations spawn;
• RFQ arguments are forwarded without economic reinterpretation;
• only approved Itô runtime or isolated node-qualification variables cross the process boundary;
• unsupported and dry-run paths fail before spawn;
• a missing or relative executable fails closed with local-install guidance;
• canonical output and exit status pass through unchanged;
• the skill, install manifests, npm surface, and opt-in MCP template stay aligned.

No test in this integration invokes a live Itô API, submits an RFQ, opens a browser, or contacts a GPU node.
