Flux Cloud MCP server

• flux_build_specFree

  Turns images, ports, resources and a term into a complete, correctly formatted v8 specification, with public ports auto-picked and data replication enabled. Returns the spec plus local validation errors and warnings.

• flux_cancel_appwrite actionFree

  Ends an app early by updating its term so it expires within about an hour. The network then uninstalls it everywhere. With confirm=true this signs and pays the (usually minimal) update; without it, returns the plan.

• flux_control_appFree

  restart: restarts containers. redeploy: pulls the image again and recreates containers (hard=true also wipes data). remove: uninstalls from nodes; the registration stays and the network re-spawns it elsewhere, so use flux_cancel_app to stop paying. Scope is one node (nodeIp) or every node running the app (global). Requires the owner key.

• flux_deploy_appwrite actionFree

  Validates the specification on a node, quotes it, and with confirm=true signs it with the Flux ID, broadcasts it and pays the quoted FLUX from the payment address. Without confirm it only returns the plan (price, balance, warnings) and spends nothing. Registers a new name or updates an existing app of the same owner. Then call flux_wait_for_app with the returned txid.

• flux_generate_keysFree

  Creates two fresh private keys (WIF): one for the Flux ID that will own apps, one for the address that pays. The response contains the secrets; store them in the MCP server environment as FLUX_ID_PRIVATE_KEY and FLUX_PAYMENT_PRIVATE_KEY, then restart the server. Nothing is stored or sent anywhere by this tool.

• flux_get_appFree

  Looks up any app on the network by name and returns its published specification, expiry, running instances and URLs.

• flux_get_app_logsFree

  Fetches the last N log lines of an app (or one component of it) from one of the nodes running it. Requires the owner key.

• flux_get_app_statsFree

  CPU, memory and network stats of the containers of an app on one node. Requires the owner key.

• flux_get_identityFree

  Returns the Flux ID (app owner address), the payment address and its spendable FLUX balance with its USD value. Explains what to configure if keys are missing. Never returns private keys.

• flux_get_network_infoFree

  Node counts by tier, current block height, FLUX/USD rate and the deployment payment address.

• flux_get_pricingwrite actionFree

  Returns the current USD rate card, the live FLUX/USD rate, the pay-in-FLUX discount and instant USD estimates for a few reference sizes. Use flux_quote_app for the exact price of a specific app.

• flux_list_my_appsFree

  Lists every app registered by the owner (or a given Flux ID) with expiry and instance counts.

• flux_quote_appFree

  Returns the Flux Cloud price for registering the given specification, or for updating it if an app of that name already exists (the unused part of the current term is credited). Price is in USD with the FLUX amount at market rate.

• flux_validate_specFree

  Runs the local rule checks, then asks a FluxOS node to verify the specification exactly as it would at registration (image reachable, architecture, ports, name availability). Returns the node-formatted spec on success.

• flux_wait_for_appFree

  Polls the network for up to timeoutSeconds (default 45 to fit hosts with a 60 s tool timeout, max 600). Returns payment confirmations, whether the spec was accepted, and the running instances with URLs. Safe to call repeatedly until done=true.
