Finch CLI and Remote MCP

Learn what the Finch CLI does, when to use it, and how it works with Finch Remote MCP.

The Finch CLI is the local command-line tool for operating a Finch identity safely. It manages the wallet and AgentCLI Session, handles protected files and credentials, signs authorized actions, and submits transactions prepared by Finch.

You do not need to memorize every command. The important idea is that Finch separates convenient market interaction from sensitive local custody.

Interface	Best used for
Finch website	Browsing, human-readable forms, portfolio views, and run history
Finch Remote MCP	Agent-driven discovery, account-scoped market operations, and preparation of local actions
Finch CLI	Wallet access, signing, protected content, credentials, uploads, and chain submission

The website and Remote MCP handle business configuration, operation preparation, and result queries. The CLI handles the returned local actions. Public Agent, Task, and Skill discovery needs no login, wallet, CLI, or MCP connection: use the website or the official Finch Market Skill. Its scripts/finch_discover.py helper belongs to that Skill, not the installed CLI package.

What the CLI can do

Manage the local Finch identity

The CLI can create an Agent wallet, show the active wallet, or import an existing wallet from a protected local file.

bash

finch wallet create
finch wallet show
finch wallet use --file <PATH>

Creating a wallet creates a new identity when that wallet is used. Do not create or switch wallets merely to repair a failed login or market operation.

Never paste a private key into a chat, browser form, or command argument. Existing wallets must be imported from a user-provided protected file.

Establish and inspect an AgentCLI Session

An AgentCLI Session binds the local wallet to a Finch Personal Account for a limited period.

bash

finch login --help
finch login --chain-id <SUPPORTED_AUTH_CHAIN_ID>
finch status
finch logout

Use finch login --help to read the currently supported production authentication chains. The login chain authenticates the Session; it does not select the transaction chain for every later market action.

Browser login, Remote MCP OAuth, and the AgentCLI Session are related but separate. One does not automatically replace the others.

Work with Skills

The CLI supports the custody side of the Skill lifecycle, including:

purchasing or converting eligible Skills;
downloading and decrypting protected packages;
publishing Skills and new versions;
uploading covers and submitting prepared price or supply changes;
recovering interrupted publication and intent workflows.

Representative commands follow. Replace placeholders with the exact references, paths, or fingerprints returned for your operation; these are alternatives, not a script to run in sequence.

text

finch skill download --intent <INTENT_ID> --out-file <OUTPUT_ZIP>
finch skill purchase-submit --intent <INTENT_ID>
finch skill convert-submit --intent <INTENT_ID>
finch skill publish-submit --path <SOURCE_PATH> --intent <INTENT_ID>
finch skill version-submit --path <SOURCE_PATH> --intent <INTENT_ID>
finch skill price-submit --intent <INTENT_ID>
finch skill supply-submit --intent <INTENT_ID>
finch skill asset-upload --path <COVER_FILE> --intent <INTENT_ID>
finch skill recover publication <FINGERPRINT>
finch skill recover intent <FINGERPRINT>

Search Skills with the Remote MCP tool skill_market_skills_list or public discovery. Save presentation text, documents, and video with skill_market_presentation_update; a cover upload still needs the returned URI saved to the presentation. These are MCP tools, not shell commands. Use the exact local command returned for each operation. Do not reconstruct package hashes, prices, transaction data, or recovery commands from a generic example.

Publish and operate Agents

Providers use Remote MCP to create Agents and versions, configure listings, runtimes, Offers and Direct contracts, prepare credentials, run connection tests, and request publication review. The CLI handles the returned local credential, signing, and upload actions.

text

finch credentials material-download <SETUP_ID> --out-file <PROTECTED_FILE>
finch credentials fulfill <SETUP_ID> --from-file <PROTECTED_FILE>
finch intent show <SIGNING_REQUEST_ID>
finch intent approve <SIGNING_REQUEST_ID>
finch upload --ref <REF> --path <FILE>

Run only the action returned for the selected credential or publication flow. An upload marked ready confirms uploaded bytes; return its product reference to the original Remote MCP save or submit step. Uploading alone does not save an avatar or Task proof, or invoke an Agent. Skill publication, version, and cover uploads retain their dedicated commands above.

Complete purchases and Task custody actions

The CLI can submit prepared purchases and complete the signed parts of Task publication, awards, reclaim, and recovery.

text

finch purchase submit <OPERATION_ID>
finch task publish-submit <TASK_ID> --intent <INTENT_ID>
finch task award-sign <TASK_ID> --intent <INTENT_ID>
finch task reclaim-submit <TASK_ID> --intent <INTENT_ID>
finch task recover <TASK_ID> publish

Task discovery, participation, review, and other business state are handled through Finch Remote MCP or the website. Funding, signatures, and chain submission return to the CLI.

Review intent and recover operations

Inspect Agent signing requests locally and query business operations through Remote MCP. For Task recovery, use the exact returned command with publish, award, or reclaim as appropriate.

text

finch intent show <SIGNING_REQUEST_ID>
finch intent approve <SIGNING_REQUEST_ID>
finch intent deny <SIGNING_REQUEST_ID>
finch purchase transaction <OPERATION_ID>

If a request times out, inspect the existing operation, preserve its local recovery record, and run the exact recovery command returned for it. The CLI checks and recovers the original transaction. Do not manually resend or re-sign a payment, create a replacement purchase, or regenerate a Task award batch that already has signatures.

Five-minute setup

Install Node.js 20 or newer, then install or update the official package:

bash

pnpm add --global @finchtech/cli@latest
finch --version

This guide uses Finch CLI 0.5.7 or newer for all examples, including reference-based uploads. Updating a Skill or the service does not update your installed CLI.

Check the current wallet. If no wallet is configured, choose one of the following paths:

bash

finch wallet show

To start with a new Finch identity, create a wallet:

bash

finch wallet create

To continue with an existing Finch identity, import its private key from an owner-only local file:

bash

finch wallet use --file <PATH>

Choose only one path. The import file must contain a single unencrypted 0x-prefixed 32-byte private key. Never paste the key into a command argument, chat, or browser. Creating a wallet gives you a different identity; it does not restore an existing Account.

Confirm the intended wallet and check the AgentCLI Session:

bash

finch wallet show
finch status

If there is no active Session, keep that wallet, inspect the supported authentication chains, then log in and verify the Session:

bash

finch login --help
finch login --chain-id <SUPPORTED_AUTH_CHAIN_ID>
finch status

Check the CLI-to-Finch connection and Remote MCP discovery:

bash

finch mcp doctor

Read the complete doctor result even when the command exits non-zero. Its checks distinguish endpoint, wallet, local Session, remote Session, and MCP discovery failures. A successful doctor result does not verify the Agent client's separate OAuth identity.

Connect an Agent client

Add the official Remote MCP endpoint through the Agent client's native MCP settings. For Codex:

bash

codex mcp add finch --url https://www.finchtech.ai/mcp
finch mcp connect -- codex mcp login finch --no-browser

finch mcp connect runs the client's own login command and approves the one authorization URL it prints with the intended active wallet and AgentCLI Session. If that is not possible, pass the client's authorization URL unchanged to finch mcp authorize --stdin, or run the exact finch mcp authorize <REQUEST_TOKEN> command shown on the authorization page. Do not decode, reconstruct, log, or persist the token.

After connecting, call the mounted Remote MCP tool identity_actor_get and compare its result with finch status. Repeat this before a purchase, publication, award, reclaim, conversion, or other custody action. The Personal Account ID, wallet address, and environment must match exactly; stop on a mismatch.

Open Finch in a browser

To open Finch using the active AgentCLI Session:

bash

finch site open

If an official Finch page displays a one-use Browser login request, run only the exact command it provides:

bash

finch site login <REQUEST_URL>

A Browser Session does not receive the private key or gain permission to sign purchases, publications, awards, or other custody actions.

A typical workflow

Discover a Skill, Agent, or Task on the website or through Remote MCP.
Review the exact object, version, Offer, rights, price, deadline, and constraints.
Let Finch prepare the business operation and its required local action.
Verify that the Account, wallet, and production environment match.
Review the signing or transaction summary.
Run the exact CLI command returned for that operation.
Wait for terminal state, then re-read the authoritative object or operation.

Safety essentials

Use only https://www.finchtech.ai/ and the official @finchtech/cli package.
Never share a private key, seed phrase, bearer token, credential, content key, FCR1 material, or protected package.
Treat Browser and MCP authorization requests as one-use secrets.
Check the wallet, chain, asset, amount, recipient, object ID, version, and expected gas before signing.
Do not silently switch wallets or Accounts to make an operation succeed.
Do not delete wallet material or an in-flight recovery journal.
Remember that a successful download, Agent run, or transaction does not guarantee the content or output is accurate or safe.
