How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security93
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Declares code that runs automatically (build-time code we could not rule out (a Hatch, PDM or setuptools build hook, a dynamic version we could not read statically, shipped VCS metadata or a stray root module)) and that we could not recognise. It may be perfectly ordinary, but we have not established what it does. View diagnostics → Partial
- 5 of 53 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100

Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 3079 tokens (~139/item across 22 items; 19 tools + 3 resources), over budget; trim descriptions and params. See how to fix → Fail

Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "gflow_instructions_rm" implies "rm" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
gflow_auth_status ~87
Non-interactive, credit-free Flow session probe (#497). Call this BEFORE a generation tool to fail fast on expired auth, before a long blocking generation call. Never starts an interactive login flow; may boot a short-lived headless browser only if cookie decryption requires the Playwright fallback. May take up to ~45s on a slow network.

Structured output declared, but exposes no named fields.

gflow_character_list ~103
List the saved Flow CHARACTER entities in a project, with their entity ids. Read-only and spends no credits. Call this to discover what you can attach: an id goes to reference_entities on the generate tools, and a display_name can be used as an @Name mention in a prompt (same wire, they dedupe). Drives a browser session, so it is slower than the catalog tools.

gflow_character_show ~91
Show one saved Flow CHARACTER entity by id or by exact display name. Read-only and spends no credits. Exactly one of entity_id or name is required; an ambiguous name is an error rather than a guess, which is the reason to prefer the id. Drives a browser session.

gflow_character_voices ~49
List the preset voices available for a Flow Character's TTS. Static lookup — no network, no browser, no cost. Call it before creating a character to choose a valid voice name.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
gflow_download_media ~213
Fetch an already-generated VIDEO from Flow by its media ID and write it to disk. For a generation that finished and was billed but whose download failed — the clip is in the Flow project and the local catalog shows no file for it. Spends no credits: the generation was already paid for. The bytes are verified against the size Flow reports before the file is written. out_dir, if given, must resolve inside the configured output directory. Video only: an image media ID is refused immediately (exit 11) because the signed URL this needs comes from a record only a clip's route emits. See issue #877. The transfer already retries a dropped connection internally, so a failure marked retryable means wait a moment and call again — never immediately, and never in a tight loop: each call opens a browser under a per-profile lease, and a second concurrent call fails on that lease instead (exit 11).

gflow_generate_image ~713
Generate an image using Google Flow's image models. Produces 1-4 images from a text prompt. output, if given, must resolve inside the configured output directory. Models: nano2 (Nano Banana 2.1, fast; 'nano2.1' also accepted), nano2-lite (Nano Banana 2 Lite), nano-pro (Nano Banana Pro), image4 (Imagen 4, no longer in Flow's menu). Aspects: 1:1, 9:16, 16:9, 4:3, 3:4. The prompt supports @AssetName mentions to tag saved project characters/assets by name (resolves to referenceEntities/referenceImages). Reference a SAVED named asset via @Name; reference an arbitrary one-off image via reference_images. See docs/REFERENCE_STRATEGIES.md. On accounts served from flow.google.com, use an existing project and local reference files. A character attaches there by name (@Name, or reference_entities paired with reference_entity_names); a UUID media reference the local catalog records in that same project is referenced in place (#995), but any other UUID, an entity id without a name, and image4 are not ported to that composer yet and fail before submit; retrying will not clear it. On an agent-only composer (#799) only text-to-image runs, so reference_images and character references fail there too. Returns local file paths to the generated images.

gflow_generate_video ~649
Generate a video using Google Flow's Veo model. Modes: t2v (text-to-video), i2v (image-to-video), r2v (reference-to-video). Aspects: 9:16, 16:9. Optional model (veo_lite/veo_fast/veo_quality/omni_flash), duration (seconds), and count select the Veo model, clip length, and batch size (CLI parity). The prompt supports @CharacterName mentions to tag saved project characters by name (resolves to referenceEntities). Reference a SAVED character via @Name; pass one-off ingredient images via reference_images. See docs/REFERENCE_STRATEGIES.md. Optional ui_mode ('classic'/'auto') verifies the classic editor pre-submit and aborts before spending credits if unreachable; 'agentic' is not supported for video. output, if given, must resolve inside the configured output directory. Returns the local file path to the generated video.

gflow_get_credits ~185
Read the current Google Flow credit balance for one saved profile or all profiles - the number Flow's account menu shows, read from flow.google.com in that profile's browser (one browser launch per profile, sequential for all_profiles). Spends no credits. Set all_profiles=true when choosing an account for generation; partial profile failures remain visible in the result. Set refresh=true to renew a signed-out session (rewrites that profile's saved cookies) in a headless browser and read again (slower - one more Chrome launch per signed-out profile; a revoked session still needs `gflow auth login`). The tier fields (sku, service_tier, user_paygate_tier, subscription_credits) are always null: flow.google.com does not report them.

What is the gflow-cli MCP server?
gflow-cli is an MCP server listed in the public MCP registry as io.github.ffroliva/gflow-cli. Drive Google Flow from an agent: Veo video and Imagen image generation. This page covers its PyPI package (gflow-cli).
Is the gflow-cli MCP server safe to use?
gflow-cli scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the gflow-cli MCP server expose?
gflow-cli exposes 19 tools: gflow_generate_image, gflow_generate_video, gflow_list_tools, gflow_list_models, gflow_get_credits, and 14 more. Their descriptions and schemas cost roughly 3,002 tokens of context every time the server is loaded.
Is the gflow-cli MCP server still maintained?
gflow-cli is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the gflow-cli MCP server under?
gflow-cli declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
