Connecting TexAu to AI Clients via MCP

This article explains how to set up the TexAu Model Context Protocol (MCP) server, authorize AI clients to call TexAu tools on your behalf, and run automated lead enrichment workflows directly from your chat interface.

🎥 Video Walkthrough

Watch this step-by-step video to see how to set up the TexAu MCP server and connect it to your AI clients:

What the TexAu MCP Server is used for

The Model Context Protocol (MCP) is an open standard that allows AI models to connect directly to external tools. Authorizing Claude, Cursor, Windsurf, Claude Code, or any other MCP client allows the AI to trigger TexAu's 249+ API endpoints directly inside your chat interface.

With no secrets or keys to manually copy into configuration files, you can use the remote MCP server to:

• Enrich local spreadsheets and files using simple conversational prompts
• Run search, web scraping, and lead verification waterfalls on autopilot
• Automatically push enriched contacts to CRMs like HubSpot or Salesforce from your chat window
• Build multi-step data pipelines entirely through conversation

💳 Pricing & 🔒 Data Privacy Policies

To keep operations lean and secure for developers, TexAu enforces the following policies for all API and MCP traffic:

• Pay-as-you-go Billing (No Monthly Subscription): The API and MCP servers have no monthly subscription fees. You only pay for the credits you consume. You can configure Auto-Reload to keep your pipelines running.
• Direct Request Pipeline (No Data Storage): To ensure maximum data privacy and GDPR/CCPA compliance, TexAu does not store any of your request data on its servers. Input parameters and output results are processed in real-time and returned directly to your AI client.

Before you begin

To connect the MCP server, you need:

• An active TexAu API account and team workspace
• An active TexAu API Key (see Getting Started with the TexAu V3 API)
• An MCP-compatible AI client installed (such as Claude Desktop, Cursor, Windsurf, Zed, or Claude Code)

Step 1: Copy your MCP Server URL

Before copying the MCP Server URL, make sure you have generated an API key.

Warning: MCP connections bill against an API key on your TexAu API account. If you do not have an active API key first, the MCP Setup page will prompt you: "You need an active API key first. MCP connections bill against an API key on your account. Create one now and we'll bring you back here."

1. Log in to your TexAu API dashboard.
2. If you haven't created an API key yet, go to API Keys in the left sidebar and click Create New Key.
3. Once an API key exists, navigate to the MCP Setup tab in the left sidebar.
4. Under MCP server URL, copy the unique remote URL (typically https://mcp.texau.com/mcp).

Step 2: Configure the connection in your AI client

The remote HTTP MCP server URL works across all major MCP-compatible tools (such as Claude Desktop, Cursor, Windsurf, Zed, and Claude Code).

While configuring Cursor or Windsurf involves editing their respective JSON configurations, this guide uses Claude Desktop as the primary setup example:

1. Open the Claude Desktop application.
2. Click the three-line menu (or gear icon) in the top corner and select Settings (or Customize).
3. Navigate to the Connectors tab.
4. Click Add custom connector.
5. In the configuration fields:
   • Name: Enter TexAu Enrich (or your preferred display name).
   • MCP Server URL: Paste the URL you copied in Step 1 (https://mcp.texau.com/mcp).
6. Click Connect.

Step 3: Authorize the AI client (OAuth Flow)

TexAu uses a secure OAuth flow to connect SaaS tools, meaning there are no secrets or credentials to copy or store inside your AI client.

1. Once you click Connect in your client, Claude will open TexAu in your default browser.
2. Sign in to your TexAu API account (or stay signed in if you already are).
3. You will see a consent screen showing which client is connecting and which TexAu API account/workspace it will bill.
4. Click Allow on the consent screen.
5. You will be redirected back to your AI client, and the TexAu tools will be immediately available.

Note: You can revoke access at any time from the Connected Apps tab in your TexAu dashboard.

Step 4: Verify the connection in chat

1. Open a new chat in Claude (or your preferred AI client).
2. Type the following prompt to test the integration:

   “Enrich the LinkedIn profile for linkedin.com/in/satyanadella”

3. Claude will query the TexAu MCP server, execute the profile enrichment tool, and display the verified lead details (such as email, job title, and company) directly in the chat.

Step 5: Run bulk lead enrichment on local files

Once connected, you can upload lead lists and have your AI client process them using TexAu tools:

1. In your chat bar, type the enrichment prompt, for example:

   "Use the TexAu Profile Enrichment tool to enrich my Excel file using the LinkedIn URLs inside."

2. Click the + (plus) icon in the chat bar and select Upload from computer.
3. Choose your local Excel or CSV spreadsheet and click Open.
4. Press Enter to submit the file.
5. When prompted by the AI client for tool execution permission, click Always Allow.
6. The AI client will read the file, extract the LinkedIn URLs, run them through TexAu's backend, and display the enriched profiles in a tabular format on the right side of the screen. You can download the completed file directly.

Troubleshooting

Claude shows a "Not Connected" error.
Ensure that your TexAu API key is still active, open Claude's connector settings, and try clicking the Connect button again to re-authorize the link in your browser.

Enrichment runs are failing or returning empty data.
Go to the Usage and Credits tab in your TexAu API dashboard to check your remaining balance. If your balance is empty, your requests will be rejected. You can enable Auto-Reload in the Buy Credits tab to automatically top up your TexAu API account whenever credits fall below a set limit.

Tool execution permissions are prompting too frequently.
When you authorize a tool run, check the Always Allow option so that Claude can execute multiple enrichment calls in sequence without prompting you for each row.
