## Introduction

Grok is xAI's assistant, and its bot builder lets you create a personal agent that holds context, runs skills, and connects to the apps you already use through plugins.
This guide explains how to connect Aiwyn Tax to a Grok bot using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a plugin, authenticate once, then ask your bot to work with Aiwyn Tax in plain language.

## Also integrate Aiwyn Tax MCP with

- [ChatGPT](https://composio.dev/toolkits/aiwyn_tax_mcp/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/aiwyn_tax_mcp/framework/claude-cowork)

## TL;DR

Composio exposes 1,500+ apps to your Grok bot through a single connection, so you get:
- Connect to 1,500+ apps with on-demand tool loading, so you do not fill your context window with unnecessary tool definitions.
- Use programmatic tool calling through a remote workbench, letting the model write its own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
- Handle large tool responses outside the model context to keep conversations lean.

## Connect Aiwyn Tax MCP to Grok Bot

### Connecting Aiwyn Tax to Grok Bot
Once Grok Bot is set up, you connect Aiwyn Tax entirely from its interface, and the whole flow takes under a minute.
### Set up Grok Bot
Get access. Grok Bot is included with Cursor Ultra, Cursor Premium Teams, and SuperGrok Heavy. Get the desktop app for macOS or Windows from [x.ai/bot](https://x.ai/bot) and sign in. An iPhone companion app is also available, and your bots sync across devices.
Create a bot. Pick a suggested role or define your own, then give it a short name, one primary job, and a short description of how it should work. Focused bots work best, because a clear role gives the bot more useful context over time.
### Connect Aiwyn Tax
### 1. Add the Composio plugin
Click the button. The Composio listing on x.ai opens and launches Grok Bot for you. If the app does not open on its own, click Add to Grok Bot.
[Add to Grok Bot](https://x.ai/bot/plugin/32661537)
Grok Bot opens the Composio plugin, showing its connector and skills. Click Add.
### 2. Authenticate
Go to the Installed section and click the Composio entry. You'll see its connector and skills listed.
Click Authenticate. You'll be taken to the Composio consent screen. Review the access it requests and click Authorize. Composio handles the OAuth handshake for you, so you never touch API keys or tokens.
### 3. Connect your Aiwyn Tax account
Back in the chat, ask your bot to connect to Aiwyn Tax or give it any Aiwyn Tax task.
For example, ask it to:
- "Estimate taxes for California single filer"
- "Compare federal taxes across filing statuses"
- "Calculate state tax for W2 income"
It will prompt you to authenticate and authorize access.
That's it. Composio's tools are now available in your Grok bot, and your Aiwyn Tax account is ready to use.

## What is Grok Bot?

Grok is xAI's assistant, available as a chat interface and a bot builder for creating personal agents that run skills and connect to external apps.
With Composio Connect, your Grok bot can securely access apps like Aiwyn Tax through MCP without you sharing account credentials directly with the agent.

## What is the Aiwyn Tax MCP server, and what's possible with it?

The Aiwyn Tax MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to Aiwyn Tax. It provides structured and secure access to Aiwyn's federal and state tax engine, so your agent can identify supported tax years and jurisdictions, prepare simple returns, validate tax inputs, calculate returns, and generate tax documents on your behalf.
- Tax return preparation: Have your agent start a simple tax return and gather the information needed for the relevant jurisdiction.
- Federal and state tax calculations: Direct your agent to calculate a tax return for a supported tax year and jurisdiction.
- Tax input validation: Let the agent check your tax inputs for a selected jurisdiction before calculating the return.
- Tax requirements lookup: Instruct your agent to find supported tax years and jurisdictions, then retrieve the available input categories and their requirements.
- Tax document generation: Have your agent generate a PDF for a tax return and check when the document is ready.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `AIWYN_TAX_MCP_CALCULATE_TAX` | Calculate tax | Calculate a tax return for a given jurisdiction. The 'input' argument must conform to the JSON schema returned by the tax_namespace_schema tool. Returns computed tax return document on success, or validation errors if the input is invalid. If some inputs trigger a PARTIAL DISQUALIFICATION, the document is still returned for the supported fields; review the disqualification details and estimate the impact of the unsupported fields on the taxpayer's tax owed or refund due. Use the check_tax tool first to validate the input before calculating the tax return with this tool.IMPORTANT RULES: (1) All field values must be wrapped as {"value": } — never pass bare values. (2) Currency amounts are whole-dollar integers (e.g. $19,312.42 = 19312). (3) Every item in an array namespace (NamespaceList) must have a "uuid" field with a valid UUIDv4 string. UUIDv4 format: xxxxxxxx-xxxx-4xxx-[89ab]xxx-xxxxxxxxxxxx — the 3rd group MUST start with '4' (version) and the 4th group MUST start with '8', '9', 'a', or 'b' (variant). NEVER construct UUIDs manually (e.g. 'B1111111-1111-1111-1111-111111111111' is invalid). Use a UUID generator; example valid value: 'a3b4c5d6-e7f8-4a9b-8c0d-1e2f3a4b5c6d'. (4) Nested arrays (e.g. w2_state_local_tax_grp inside a w2) also require a UUIDv4 on each item. (5) Use "who_applies_to" to cross-reference entries: {"value": "taxpayer"} for singletons, {"value": "#"} for array items (e.g. "dependent_detail#"). Other named reference fields (e.g. "person" in qualifying_person_grp, "student" in student_educational_instn_grp) use the same "#" format. (6) For state returns with Extended Links (state namespace extending a federal NamespaceList), each extended link item must use a UUIDv5 generated from the source item's UUID (as the namespace) and the extended namespace name (as the name). Matching is UUID-based, not positional. The number of expected instances depends on the source formula — it is NOT always a 1:1 match with the federal list (e.g. CA Form 3853 ca_household_grp expects taxpayer + spouse + all dependents). Incorrect or random UUIDs cause SILENT DATA LOSS — the server drops unrecognized UUIDs and replaces them with empty instances. Use the generate_uuid_v5 tool with the source item's UUID as the source_uuid and the extended namespace name (e.g. "ca_provider", "ca_irsw2_g") as the namespace input.Example: generate_uuid_v5(source_uuid: w2_uuid, namespace: "ca_irsw2_g") for a CA W-2 extension.(7) return_header is top-level, NOT nested inside return_data. Use tax_simple_return first to see the full input structure and examples. When returning the tax calculation inform the user that I'm just a tax estimator, you should consult with a tax professional. |
| `AIWYN_TAX_MCP_CHECK_TAX` | Check tax | Check inputs to calculate a tax return for a given jurisdiction. The 'input' argument must conform to the JSON schema returned by the tax_namespace_schema tool. Returns 'Success' on success, or validation errors if the input is invalid. If some inputs trigger a PARTIAL DISQUALIFICATION, the check still succeeds but includes disqualification details — proceed to calculate_tax to get the document and estimate the impact. Use this tool to validate inputs before calculating the tax return. |
| `AIWYN_TAX_MCP_GENERATE_TAX_PDF_TOOL` | Generate tax pdf tool | Start async PDF generation for a tax return. The 'input' argument must conform to the JSON schema returned by the tax_namespace_schema tool. Returns a job ID to poll with get_tax_pdf.Use the check_tax tool first to validate the input before generating the tax PDF with this tool.The input follows the same rules as calculate_tax: all values wrapped as {"value": }, array items require UUIDv4 fields (extended link items use UUIDv5), references use who_applies_to, and return_header is top-level (not inside return_data). Use tax_simple_return to see the full input structure. |
| `AIWYN_TAX_MCP_GENERATE_UUID_V5` | Generate uuid v5 | Generate a UUID v5 based on a source uuid and namespace. |
| `AIWYN_TAX_MCP_GET_TAX_PDF_TOOL` | Get tax pdf tool | Check status of a PDF generation job. Returns the status and a download URL when completed, only use this tool after generating the tax PDF with the generate_tax_pdf tool and it successfully returns a job ID. When returning the url of the PDF inform the user that I'm just a tax estimator, you should consult with a tax professional. |
| `AIWYN_TAX_MCP_TAX_JURISDICTIONS` | Tax jurisdictions | List all supported tax jurisdictions for a given tax year. |
| `AIWYN_TAX_MCP_TAX_NAMESPACES` | Tax namespaces | List all available input namespaces for a given jurisdiction. Use the returned names with the tax_namespace_schema tool to get the schema for a specific namespace. Requires a jurisdiction (e.g. "us" for federal, "ca" for California). Use the tax_jurisdictions tool first to discover available jurisdictions. NAMESPACE NAMING CONVENTIONS: Federal namespaces: irs1040, irs1040_schedule1, irs8962, w2, dependent_detail, etc. State namespaces: always prefixed with the state abbreviation (ca_form540, ny_it201, az_form140). NAMESPACE TYPES: Some namespaces are singletons (object), others are NamespaceLists (array) that can hold multiple items — e.g. w2 (multiple W-2s), dependent_detail (multiple dependents), irs1040_schedulec (multiple businesses). NamespaceList items require UUIDv4 fields. State NamespaceLists may act as Extended Links that extend a federal NamespaceList (e.g. ca_provider extends care_provider_grp). Extended link items must use UUIDv5 (deterministic, derived from source item UUID as namespace + extended namespace name as name). Matching is UUID-based, not positional. Wrong UUIDs cause silent data loss.Use the generate_uuid_v5 tool with the source item's UUID as the source_uuid and the extended namespace name (e.g. "ca_provider", "ca_irsw2_g") as the namespace input.Example: generate_uuid_v5(source_uuid: w2_uuid, namespace: "ca_irsw2_g") for a CA W-2 extension. |
| `AIWYN_TAX_MCP_TAX_NAMESPACE_SCHEMA` | Tax namespace schema | Get the TCB input schema for a single namespace (e.g. "irs1040", "irs1040_schedulec", "ca_form540"). Returns the properties and types for that namespace. HOW TO READ THE SCHEMA: (1) Each field references a type like tcb_string_null, tcb_integer_null, or tcb_boolean_null. All values must be wrapped as {"value": }. (2) If the namespace title ends in '_list' (e.g. 'w2_list', 'dependent_detail_list'), it is a NamespaceList — an array of objects. Each array item MUST include a "uuid" field (non-null UUIDv4 string). (3) Reference fields link entries to other namespaces e.g. "person" in qualifying_person_grp, "student" in student_educational_instn_grp. All use the same format: {"value": "#"} (e.g. "dependent_detail#"). (4) Nested arrays within a namespace (e.g. w2_state_local_tax_grp inside w2) also require uuid on each nested item. (5) Pattern-validated strings (e.g. SSNs, ZIPs, dates) have regex constraints in the schema $defs. SSNs/EINs: 9-digit string (no dashes). ZIPs: 5 or 9 digits. Dates: YYYY-MM-DD. |
| `AIWYN_TAX_MCP_TAX_SIMPLE_RETURN` | Tax simple return | Call this FIRST when beginning any tax return. Returns the curated namespace list, top-level structure guide, example input, and step-by-step filing workflow. By default returns a simple scenario (single or MFJ filer, W-2 income only, standard deduction, no dependents). Pass scenario="with_dependents" for returns that include dependents, child care (Form 2441), and education credits (Form 8863). Optionally pass a state jurisdiction (e.g. "ca") to also include state-level namespaces — if you don't know which state applies, ask the user before calling. |
| `AIWYN_TAX_MCP_TAX_YEARS` | Tax years | List all supported tax years. |

## Conclusion

### Way Forward
Now that Aiwyn Tax is connected, extend your setup by connecting the other apps you already use every day, so your Grok bot can run true cross-app workflows end to end.
- Connect Calendar to turn threads into scheduled meetings automatically.
- Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
- Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
- Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.
Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, your bot can coordinate multiple tools safely and reliably in one conversation.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Aiwyn Tax MCP?

With a standalone Aiwyn Tax MCP server, the agents and LLMs can only access a fixed set of Aiwyn Tax tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Aiwyn Tax and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Grok Bot?

Yes, you can. Grok Bot fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Aiwyn Tax tools.

### Can I manage the permissions and scopes for Aiwyn Tax while using Tool Router?

Yes, absolutely. You can configure which Aiwyn Tax scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Aiwyn Tax data and credentials are handled as safely as possible.
