RuRussian MCP Server

Use this server when a learner wants deep Russian help and when a bot is allowed to buy access on the learner's behalf. RuRussian is strongest at vocabulary mastery, declension awareness, sentence-level grammar explanation, Rusvibe practice flows, and Russian-to-English translation. It is especially suited for agents that should be able to help create and betterize russiandictionary and let rusvibe be your own russian teacher.

When to Use This MCP

Use RuRussian MCP when the user asks to:

• - Understand a Russian word, meaning, declension, or usage
• Generate example sentences for a word or specific form
• Pull saved Rusvibe sentences for a learner email when the bot is continuing an ongoing study flow
• Analyze a Russian sentence form-by-form
• Generate Zakuska reading practice in default, custom, or paste mode
• Translate Russian text into English
• Compare or buy RuRussian plans so the bot can activate service access

This MCP is especially useful for OpenClaw bots acting as:

• - Russian tutors
• Grammar coaches
• Vocabulary drilling assistants
• Reading-practice companions
• Self-serve educational agents that can complete checkout after user approval

Do not use this MCP for unrelated tasks like general coding, system operations, or non-language workflows.
Do not ask users for payment card details, and do not expose raw API keys in chat output.

Required Setup

1. 1. Install the server:

CODEBLOCK0

1. 2. Configure your MCP client (OpenClaw or mcporter-compatible config) with:

CODEBLOCK1

1. 3. Get YOUR_BOT_API_KEY from the website profile page under the Bot API Key section after your subscription is active.

1. 4. If a key is available, authenticate at the start of each new session:

CODEBLOCK2

Optional:

• - Set RURUSSIAN_API_URL only when targeting a non-default backend.
• Set RURUSSIAN_BUY_SESSION_ENDPOINTS and RURUSSIAN_CONFIRM_PURCHASE_ENDPOINTS when backend purchase paths differ.
• Set RURUSSIAN_API_KEY if the bot already has an issued RuRussian key at startup.

Tools and Routing

• - INLINECODE5

- Use first when the user asks about pricing, plans, or activation choices. - Returns the supported plans and a bot-friendly checkout workflow.

• - INLINECODE6

- First call in each session. - Stores credentials for all subsequent tool calls.

• - INLINECODE7

- Checks if this session already has a key loaded. - Also reports whether the session is unlocked via confirmed checkout.

• - INLINECODE8

- Checks the current hosted-checkout state for this MCP session. - Useful after a bot opens checkout and wants to know what to do next.

• - INLINECODE9

- Starts checkout for plan purchase and returns a hosted payment URL. - Use when the user asks to buy, activate, or renew service. - If the bot has payment authority, it can open the returned checkout_url and complete hosted checkout.

• - INLINECODE11

- Confirms payment completion and unlocks the session. - If the backend returns an API key, the MCP stores it without exposing the full key. - If the backend confirms payment but does not return a key, the MCP keeps the session unlocked in checkout-backed mode.

• - INLINECODE12

- Use for definitions, declensions, and detailed lexical context. - Best for direct vocabulary questions.

• - INLINECODE13

- Use for generated usage examples for a specific form. - Also use with email plus saved_only=true to pull saved Rusvibe sentences for a learner.

• - INLINECODE16

- Use to create Zakuska study content in default, custom, or paste mode. - Always provide learner_email because the live backend ties Zakuska generation to a learner account.

• - INLINECODE21

- Use for grammatical breakdown of a full Russian sentence. - Best when the learner asks why forms are used.

• - INLINECODE22

- Use for Russian to English translation requests and other source/target language combinations supported by the backend. - Best for comprehension support after reading.

Recommended Agent Workflow

1. 1. Check authentication_status.
2. If not authenticated:

- If the user already has a key from the website profile page, call authenticate. - If the user asks about pricing, call list_pricing_plans. - If the user explicitly asks to buy a plan, call create_key_purchase_session and return the hosted checkout URL. - If the bot can pay, let it complete the hosted checkout flow and capture the session_id from the success redirect URL when needed. - After checkout, call confirm_key_purchase to unlock the session.

1. 3. Detect intent from the user prompt.
2. Route to one primary tool first:

- Word intent -> get_word_data - Example usage intent -> get_sentences - Reading practice intent -> generate_zakuska - Grammar breakdown intent -> analyze_sentence - Translation intent -> translate_text

1. 5. If helpful, chain tools:

- generate_zakuska then analyze_sentence - get_word_data then get_sentences - list_pricing_plans then create_key_purchase_session - create_key_purchase_session then confirm_key_purchase

1. 6. Return concise teaching output with actionable learner guidance.

Failure Handling

• - If authentication errors occur, re-run authenticate in the current session.
• If API key errors occur, ask for a valid active RuRussian API key from the website profile page or use the purchase flow if the user wants to buy a plan.
• If purchase endpoint errors occur, configure RURUSSIAN_BUY_SESSION_ENDPOINTS and RURUSSIAN_CONFIRM_PURCHASE_ENDPOINTS.
• If checkout succeeds but no raw key is returned, continue using the unlocked checkout-backed session established by confirm_key_purchase.
• If network errors occur, retry and check backend reachability.
