genai-calling

This skill is named genai-calling in this repository.

The runtime package is genai-calling, the Python import path is

gravtice.genai, and the environment variable prefix is

GENAI_CALLING_*.

Quick Start

IMPORTANT: If you rely on project-local .env.* files, run commands in the

directory that contains those files (typically this skill base directory). If

no project-local env file is present, the runtime also falls back to

~/.genai-calling/.env. If you pass runtime env vars (inline/export), working

directory is not restricted.

# 1) Create `.env.local` in this skill directory
(cd "<SKILL_BASE_DIR>" && { test -f .env.local || touch .env.local; })

# 2) Edit `<SKILL_BASE_DIR>/.env.local` and set at least one provider key (see "Configuration Templates" and "Supported Environment Variables").
# Example (OpenAI):
#   OPENAI_API_KEY=...

# 3) Text
(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai --model openai:gpt-4o-mini --prompt "Hello")

# 4) See what you can use (requires at least one provider key configured)
(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai model available --all)

For user-wide defaults shared across projects, create ~/.genai-calling/.env

and put provider credentials there. Project-local .env.* files still win.

If uvx is unavailable, install once and use genai directly:

python -m pip install --upgrade genai-calling
(cd "<SKILL_BASE_DIR>" && genai --model openai:gpt-4o-mini --prompt "Hello")

Configuration (Env Vars, Zero-parameter)

Configuration is managed via environment variables.

You can set env vars in two ways:

Runtime env vars (inline before command, or export in shell)
Env files (.env.local, .env.production, .env.development, .env.test, ~/.genai-calling/.env)

Recommended for this skill:

Put reusable provider credentials in ~/.genai-calling/.env
Put project-level overrides in /.env.local
Use runtime env vars for one-off overrides

Runtime example (inline):

(cd "<SKILL_BASE_DIR>" && OPENAI_API_KEY=... uvx --from genai-calling genai --model openai:gpt-4o-mini --prompt "Hello")

When env files are used, SDK/CLI/MCP loads them automatically with priority (high -> low):

.env.local > .env.production > .env.development > .env.test > ~/.genai-calling/.env

Process env vars override file-based config.

Minimal .env.local (OpenAI text only):

OPENAI_API_KEY=...
GENAI_CALLING_TIMEOUT_MS=120000

Minimal ~/.genai-calling/.env:

OPENAI_API_KEY=...
GOOGLE_API_KEY=
ANTHROPIC_API_KEY=

Notes:

Do not commit .env.local (add it to .gitignore if needed).
~/.genai-calling/.env is user-level config and should hold only values you want shared across projects.
Provider credentials should use the shorter provider-specific variable names such as OPENAI_API_KEY.

Recommended usage:

Put shared provider credentials in ~/.genai-calling/.env
Put project-specific overrides and MCP settings in /.env.local
Keep only the providers and options you actually use

Supported Environment Variables

Common runtime

GENAI_CALLING_TIMEOUT_MS (default: 120000)
GENAI_CALLING_URL_DOWNLOAD_MAX_BYTES (default: 134217728)
GENAI_CALLING_ALLOW_PRIVATE_URLS (1/true/yes to allow private/loopback URL download)
GENAI_CALLING_TRANSPORT (internal transport marker; MCP server uses mcp, legacy sse is accepted)

Provider credentials

OpenAI: OPENAI_API_KEY
Google (Gemini): GOOGLE_API_KEY
Anthropic (Claude): ANTHROPIC_API_KEY
Aliyun (DashScope/百炼): ALIYUN_API_KEY
Volcengine (Ark/豆包): VOLCENGINE_API_KEY

Provider base URL overrides

ALIYUN_OAI_BASE_URL (default: https://dashscope.aliyuncs.com/compatible-mode/v1)
VOLCENGINE_OAI_BASE_URL (default: https://ark.cn-beijing.volces.com/api/v3)

Quick guidance:

Most users only need one provider key plus GENAI_CALLING_TIMEOUT_MS
Only set GENAI_CALLING_ALLOW_PRIVATE_URLS if you explicitly want to bypass private URL protection
Only set MCP variables when you run genai-mcp-server

Model Format

Model string is {provider}:{model_id} (example: openai:gpt-4o-mini).

Use this to pick a model by output modality:

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai model available --all)
# Look for: out=text / out=image / out=audio / out=video / out=embedding

If you have not configured any keys yet, you can still view the SDK curated list:

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai model sdk)

Common Scenarios

Image understanding

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai --model openai:gpt-4o-mini --prompt "Describe this image" --image-path "/path/to/image.png")

Image generation (save to file)

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai --model openai:gpt-image-1 --prompt "A red square, minimal" --output-path "/tmp/out.png")

Speech-to-text (transcription)

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai --model openai:whisper-1 --audio-path "/path/to/audio.wav")

Text-to-speech (save to file)

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai --model openai:tts-1 --prompt "你好" --output-path "/tmp/tts.mp3")

Python SDK

Install:

python -m pip install --upgrade genai-calling

Minimal example:

from gravtice.genai import Client, GenerateRequest, Message, OutputSpec, Part

client = Client()
resp = client.generate(
    GenerateRequest(
        model="openai:gpt-4o-mini",
        input=[Message(role="user", content=[Part.from_text("Hello")])],
        output=OutputSpec(modalities=["text"]),
    )
)
print(resp.output[0].content[0].text)

Note: Client() loads project-local .env.* from the current working

directory and then falls back to ~/.genai-calling/.env; run your script in

the directory that contains your project env files, or export env vars in the

process environment.

MCP Server

Start server (Streamable HTTP: /mcp, SSE: /sse):

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai-mcp-server)

Recommended: set auth via runtime env vars, .env.local, or

~/.genai-calling/.env before exposing the server:

# GENAI_CALLING_MCP_BEARER_TOKEN=sk-...

Debug with MCP CLI:

(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai-mcp-cli env)
(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai-mcp-cli tools)
(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai-mcp-cli call list_providers)
(cd "<SKILL_BASE_DIR>" && uvx --from genai-calling genai-mcp-cli call generate --args '{"request":{"model":"openai:gpt-4o-mini","input":"Hello","output":{"modalities":["text"]}}}')

Troubleshooting

Missing/invalid API key (401/403)

Set provider credentials via runtime env vars, /.env.local,

or ~/.genai-calling/.env (see "Supported Environment Variables"), then retry.

File input errors (mime type)

If you see cannot detect ... mime type, verify the path exists and is a valid image/audio/video file.

Timeout / long-running jobs

Increase GENAI_CALLING_TIMEOUT_MS (runtime env var, .env.local, or

~/.genai-calling/.env) and retry.

URL download blocked / SSRF protection

Binary outputs may be returned as URLs. Private/loopback URLs are rejected by default. Only if you understand the risk, set GENAI_CALLING_ALLOW_PRIVATE_URLS=1.

MCP auth (401 Unauthorized)

Set GENAI_CALLING_MCP_BEARER_TOKEN (or GENAI_CALLING_MCP_TOKEN_RULES) via

runtime env var, .env.local, or ~/.genai-calling/.env, and ensure

genai-mcp-cli uses the same token.
