Web app

filecoin-app has three parts:

• Explorer (/mainnet, /calibration): public pages for data sets, pieces, storage providers, Filecoin Pay rails and settlements, session keys, and each address. Search with / or ⌘K from any page.
• Dashboard (/dashboard): connect a wallet to manage your Filecoin Pay account, the Warm Storage approval, data sets, uploads, rails, and session keys.
• Setup page (/dashboard/setup): review and approve a request from filecoin or an agent.

Session keys

A session key lets a tool sign storage requests for your wallet. It can create data sets, add pieces, schedule piece removals, and end service, but it can never move funds. Keys you make in the dashboard stay in this browser. Keys made by filecoin login stay on the agent's machine, and the dashboard only approves them.

The session keys page lists every key your wallet approved, with when each permission expires. Revoke a key there to stop the tool that holds it.

Setup links

filecoin login, filecoin status, and the put funding check send the wallet owner to /dashboard/setup. The page fills in the request from the link, and you review it, change what you need, and approve each step with your wallet. Each step is its own transaction, so nothing is signed until you click.

Parameter	Meaning
network	mainnet or calibration. The page asks to switch the wallet when it is on the other network
signer	Session key address to approve. The private key stays with the tool that made it
name	Session key name, up to 64 characters, recorded on chain. Default: filecoin-app
scopes	Comma-separated permissions: createDataSet, addPieces, schedulePieceRemovals, terminateService. Default: the first three
days	Days until the approval expires, from 1 to 365. Default: 30
deposit	USDFC to deposit, as a decimal amount

Every parameter is optional, and the page drops an invalid value instead of failing. The Warm Storage step appears whenever the wallet has not approved it.

WebMCP tools

filecoin-app registers WebMCP tools, so a browser agent can prepare a setup request and read the account and its storage:

Tool	Where	What it does
prepare_setup_request	Every page	Checks a request with the parameters above and opens the prefilled setup page. It never signs anything
get_setup_status	/dashboard/setup	Reports whether a wallet is connected and on Filecoin, and which requested permissions are approved
get_account_summary	Every page	Reports a wallet's Filecoin Pay funds, monthly spend, runway, and Warm Storage approval
list_data_sets	Every page	Lists a wallet's data sets
list_pieces	Every page	Lists a data set's pieces, each with a retrieval link
lookup_piece	Every page	Finds the data sets that hold a PieceCID v2
list_session_keys	Every page	Lists the session keys a wallet approved

The read tools default to the connected wallet and the network in the page address. WebMCP is an early preview. It works in Chrome 149 and later on poc.filecoin.cloud, and in the ChatGPT desktop app's browser, where the tools are called site tools. Other browsers ignore the tools, and agents use setup links instead.
