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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 5 of 54 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency35
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: the license (MIT License) isn't a recognized OSI-approved license. See how to fix → Fail
- Actively maintained (last published 1 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability81
- 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
- Tool/resource definitions use about 1711 tokens (~90/item across 19 items; 16 tools + 3 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
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

Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the gflow-cli MCP server?
gflow-cli runs locally as a PyPI package, launched with uvx gflow-cli. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

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 ~97
Non-interactive, credit-free Flow session probe (#497). Call this BEFORE a generation tool to fail fast on expired auth — the queue is async, so an auth failure otherwise surfaces only later from the daemon. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| profile | string | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| profile | string | – | – |
| project | string | yes | – |
Structured output declared, but exposes no named fields.
No examples provided.
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.
| Name | Type | Req | Description |
|---|---|---|---|
| entity_id | – | – | – |

| profile | string | – | – |

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 ~140
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. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| media_id | string | yes | – |
| out_dir | – | – | – |
| profile | – | – | – |
Structured output declared, but exposes no named fields.
No examples provided.
gflow_generate_image ~281
Generate an image using Google Flow's Imagen model. Produces 1-4 images from a text prompt. Models: nano2 (fast), nano-pro (balanced), image4 (highest quality). 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; UUID/entity references and image4 are not ported to that composer yet and fail before submit; retrying will not clear it. Returns local file paths to the generated images.

gflow_generate_video ~304
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. Returns the local file path to the generated video.

gflow_get_credits ~70

gflow_instructions_add ~97

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 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. 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 16 tools: gflow_generate_image, gflow_generate_video, gflow_list_tools, gflow_get_credits, gflow_character_list, and 11 more. Their descriptions and schemas cost roughly 1,634 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 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
