Image Gen

com.nuverlabs/image-genv0.2.1AI & LLMs

Generate and edit images from your coding agent with Gemini and OpenAI, using your own API keys.

In-path gate · all MCP tools

Using Image Gen in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

uv tool install mcpindex-gate && mcpindex-config-wire

Trust verdict · v1 advisory · method

NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-08-13).

Contracts can change after screening, with no version bump. The gate pins Image Gen’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables

GEMINI_API_KEY

secret

Google Gemini API key. Enables the Gemini provider. At least one provider key is required.

OPENAI_API_KEY

secret

OpenAI API key. Enables the OpenAI provider. At least one provider key is required.

IMAGE_GEN_MCP_DEFAULT_PROVIDER

Provider used when a tool call does not name one: gemini or openai. Defaults to whichever key is set, preferring gemini.

IMAGE_GEN_MCP_GEMINI_MODEL

Default Gemini model. Defaults to gemini-3.1-flash-image.

IMAGE_GEN_MCP_OPENAI_MODEL

Default OpenAI model. Defaults to gpt-image-2.

IMAGE_GEN_MCP_OUTPUT_DIR

Directory used when a tool call passes no output_path.

IMAGE_GEN_MCP_ALLOWED_DIRS

Comma separated directories that file reads and writes are confined to. Unset means unrestricted.

IMAGE_GEN_MCP_TIMEOUT_MS

Per-request timeout to the provider API in milliseconds. Defaults to 180000.

IMAGE_GEN_MCP_LOG_FILE

Path of the JSONL image ledger. Defaults to ~/.image-gen-mcp/images.jsonl. Set to none to disable the file.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 962,237). Verify it yourself.
