Tools

`search_templates`

Find Poly-Glot prompt templates by keyword, goal, or plan. Results include whether each template is currently locked for the account.

Parameters: query (string), goal (string), plan ("free" | "pro"), limit (1–24, default 12), uiLanguage (string, default "EN")

`get_template`

Get a template's fields and prompt body. The source prompt body is returned only when the account is entitled to use the template.

Parameters: name (string, required), uiLanguage (string, default "EN")

`build_prompt`

Fill an entitled Poly-Glot template with user values. First use of a free template starts the 3-day trial. Pro templates require an active Pro subscription.

Parameters: name (string, required), values (object), uiLanguage, inputLanguage, outputLanguage (strings, default "EN")

`prepare_compare`

Prepare one canonical prompt for 2+ AI providers so the user can compare answers side-by-side. Does not call third-party models on the user's behalf.

`get_language_options`

Return the 38 supported Poly-Glot UI, input, and AI output languages. Language selection never changes entitlement.

Parameters: uiLanguage (string, default "EN")

`get_subscription_status`

Return the current Poly-Glot trial or Pro entitlement state and current pricing.

Parameters: none

`open_workspace`

Open the interactive Poly-Glot template browser and prompt editor with subscription-aware locked states. In UI-capable MCP hosts (ChatGPT), renders the full embedded GUI inside the conversation.

Parameters: query (string), uiLanguage (string, default "EN")

`transcribe_audio`

Transcribe audio content and return text. Supports language detection and forced source language. Requires entitlement.

Parameters: audioUrl (string, required), sourceLanguage (string), uiLanguage (string, default "EN")

`detect_language`

Detect the language of a text snippet. Returns ISO code and confidence score.

Parameters: text (string, required), uiLanguage (string, default "EN")

`translate_text`

Translate text between any of the 38 supported Poly-Glot languages.

Parameters: text (string, required), from (string), to (string, required), uiLanguage (string, default "EN")

`localize_text`

Localize text for a target locale — adapts tone, units, date formats, and cultural references beyond simple translation.

Parameters: text (string, required), targetLocale (string, required), context (string), uiLanguage (string, default "EN")

`get_custom_model_capabilities`

Return supported BYOM adapter modes, credential policy, network restrictions, and notes about localhost access.

Parameters: none

`validate_custom_model`

Validate a developer-supplied model endpoint. Checks HTTPS, SSRF, and optionally probes the model. API keys are transient and never persisted or echoed.

Parameters: adapterMode ("openai-compatible" | "custom-rest"), baseUrl (string), endpoint (string), model (string), apiKey (string, transient), probe (boolean)

`run_custom_model`

Run a Poly-Glot prompt against a developer-supplied model endpoint. Applies language instructions and respects entitlement checks.

Parameters: adapterMode ("openai-compatible" | "custom-rest"), baseUrl/endpoint (string), model (string), apiKey (string, transient), prompt (string, required), system (string), temperature, maxTokens, uiLanguage, inputLanguage, outputLanguage

`prepare_custom_compare`

Build a Compare Mode plan containing built-in providers and developer-supplied custom model descriptors. Credentials are supplied at execution time only.

Parameters: prompt (string, required), builtinProviders (array), customModels (array of { label, adapterMode, baseUrl/endpoint, model }), uiLanguage, inputLanguage, outputLanguage
