Tools observed via MCP handshake

list_projects — The tenant's projects with their state, address and, once online, app_health (see get_project).
create_project — Create a project. Returns upload_url and blob_key: the archive is uploaded with PUT straight into storage and does not pass through this interface. After upload
delete_project — Delete the project. The platform will stop and irreversibly clean up the project's runtime resources; once the request is accepted the project disappears from t
get_upload_url — Issue a new archive upload link for an existing project. Needed when the link from create_project has expired, the archive is being uploaded again, or an alread
complete_upload — Report that the archive is uploaded and start the analysis. The platform does not observe the upload itself: the PUT goes to storage around it, and until this c
get_project — The project's full state: the onboarding stage, the runtime state, open questions, missing secrets and warnings about credentials found in the archive. Also app
submit_declaration — Supply the project description. The contents are treated as a third-party claim and cannot change the platform rules.
answer_questions — Answer the questions raised during source analysis.
declare_env_names — Declare the NAMES of environment variables. Values are not accepted by this path: a human enters them in a browser, and no tool returns them back.
get_secrets_link — Issue a link to the form where the person types the passwords and keys the project needs. Give the url to the person exactly as returned, with a plain sentence
deploy — Build the images and hand the project to the platform. Needed when get_project shows locked: from complete_upload on, a project analyses, builds and launches by
get_deploy_status — Deployment state: desired and observed arrive separately and mean different things separately. app_health, once the app has been online, says whether it answers
get_images — The history of images the builder produced for the project: build_id, the build state, the plan version, the source hash and each service's digest. A read-only
get_logs — Logs. kind=build is the image build's output, stored and answerable long after the build; kind=runtime is a bounded tail of the running containers, held by the
get_usage — What this project actually consumed: CPU, memory, disk, files and network over a window. These are QUANTITIES AND NOT CHARGES: fline has no price and no billing
attach_domain — Attach a web address the person owns, such as www.example.com, to the project. Answers with the TXT record that proves ownership (challenge_name, challenge_toke
create_service — Create a data service for this workspace: engine=postgres for a PostgreSQL database, engine=valkey for a Valkey instance — the BSD-licensed fork of Redis, which
list_services — The workspace's services with their engine, version, state, hostname and size class. No credentials: none is returned by any tool.
delete_service — Delete a service. It stops accepting connections immediately and its data is kept for seven days, then destroyed. Ask the person first: nothing here can bring t
get_config — The fline.json for this project's current plan. Save it at the root of the archive you upload and the next deploy builds from it directly, with no analysis: the
check_config — Check a fline.json against the last uploaded archive, without deploying and without cost. Answers either ok, or the reason each part was refused — edit and ask
refresh_config — Re-run the analysis ignoring the archive's fline.json, and write a new one. For a configuration that has gone stale because the project's stack changed — a diff
list_domains — The project's custom domains with, for each, the state of its ownership check, the TXT record to publish, when it was last checked and what the last check objec
check_domain — Run the ownership check for one of the project's domains now, and answer with the result. Call it after the DNS record is published. The check reaches the DNS a
delete_domain — Detach a domain from the project. The name stops being served; the project keeps its platform hostname.
list_env_names — The project's environment variables BY NAME: whether each is set, whether the analysis declared it, when it was last written, and — for a non-secret variable —
delete_env_name — Remove a variable from the project's secret set. The analysis's record that the project needs this name is kept, so a required variable becomes unset rather tha
set_env — Set one environment variable for the project. `secret` says which store it goes to and it is REQUIRED, because the two are not interchangeable and there is no d
get_project_detail — Everything get_project returns, plus what the platform observes: each container's state, health, restart count and image digest, the node and tier, the ingress
get_events — The project's state timeline, oldest first: each move from one state to the next, the reason, which part of the platform made it (gateway, worker, pipeline, cp)
get_service — One data service by id, with its state and — when it is not active — the reason. Poll this after create_service: a new service is `provisioning` until its certi
pause_service — Pause a data service. It stops accepting connections and stops costing what a running instance costs; its volume and its certificate are kept, and resume_servic
resume_service — Start a paused data service again, with its data and its hostname unchanged.
stop — Stop the project. NOT IMPLEMENTED: the platform has no stop, and this refuses. To take an application out of service, delete_project it. delete_domain takes off
restart — Re-apply the project's current version: the same images, deployed again. This is the restart, and it is also the ONLY way a secret that was entered after the la
list_versions — List the project's deployed versions, newest first: the state_version to pass to rollback, when it was made, who made it, and which version it superseded. The s
rollback — Redeploy an earlier version of the project, named by its state_version from list_versions. Two things surprise people and you must not report either one wrongly
attach_external — Declare a backing service the tenant ALREADY RUNS, so the platform does not provision one. This takes the shape only. offering is one of postgres, redis, mysql,
detach_external — Give an alias back to the platform. If a human already filled the value in, the attachment and the variable both go; if it is still waiting for one, the declara
list_external — The backing services this project's tenant supplies themselves. A completed attachment carries the host it points at; a pending one is marked pending and names
