Your AI assistant,plugged into your competitors
Sendsitive is a competitor email and SMS tracking platform with a built-in MCP server. Connect Claude, ChatGPT, Cursor or Codex and your assistant can query your competitors' real emails and texts on demand. No exports. No copy-paste. No made-up numbers.
Works with Claude, ChatGPT, Codex and Cursor · OAuth sign-in or revocable bearer keys · Runs on your Sendsitive AI credits
Ask in plain English
"How much did each competitor send this week?" "When is my category quietest?" Sendsitive turns the question into structured queries against your account.
Grounded in your data
The assistant only sees what your organization tracks. Numbers come from your archive, not from training data, and every tool is read-only.
Stays in the tool you use
No second dashboard. Sendsitive becomes another capability inside Claude Desktop, the ChatGPT connectors panel, or Cursor's chat.
Email AND SMS
Sendsitive tracks both channels, so your assistant can answer channel-mix questions no email-only tool can.
What your assistant can call
Four structured, read-only tools the AI invokes automatically. No prompt engineering required.
Scope note: these tools answer questions about VOLUME, TIMING and detected insights across your competitive set. Reading individual campaigns (subject lines, creative, full message bodies) lives in the dashboard for now, not over MCP. Each tool call draws from the same usage credits as Sendsitive AI.
| Tool | What it returns | Use case |
|---|---|---|

| org_analytics | Aggregate send analytics across all your competitors over a date window: email and SMS totals, per-day volume trend, and cadence. | Aggregate |
| send_timing | Hour-of-day and day-of-week distribution of competitor sends, so your assistant can answer when your category actually hits inboxes. | Timing |
| competitor_insights | AI-generated competitive insights Sendsitive has detected: notable changes, patterns, and recommended actions, newest first. | Strategy |
Things you'll actually ask
"Catch me up"
How much did each competitor send this week compared with last week? Flag anyone who went quiet or spiked.
"Pick a fight"
Rank my competitors by send volume over the last 30 days and show how each one splits between email and SMS.
"Find the window"
When is my category quietest? Use send timing to find the day and hour where my next campaign would stand out most.
"What changed?"
Pull the latest competitor insights and tell me which ones I should act on this week, ordered by impact.
"Channel check"
How much of my competitors' volume is SMS versus email this month, and who leans hardest on text?
"Brief my team"
Write a one-paragraph competitive summary I can paste into Slack, based on this month's analytics and insights.

}Frequently asked questions
Is there an MCP server for tracking competitor emails?
Yes. Sendsitive is a competitor email and SMS tracking platform with a built-in MCP server. It collects the marketing emails and texts your competitors send, and its MCP server lets Claude, ChatGPT, Cursor, Codex or any MCP client query that data in plain language.
How do I track competitor emails from Claude or ChatGPT?
Add your competitors in Sendsitive, then connect the Sendsitive MCP server to Claude or ChatGPT with OAuth sign-in or an API key from Settings. Your assistant can then list your competitors, compare their email and SMS volume, find when they send, and pull the latest competitive insights.
What competitor data can the Sendsitive MCP return?
Four read-only tools: the competitors you track, aggregate email and SMS send analytics over any date window, hour-of-day and day-of-week send timing, and AI-generated competitive insights. Every answer comes from emails and texts Sendsitive actually received.
Can the assistant change my data?
No. Every exposed tool is read-only. Your assistant can list, aggregate, and search; it cannot edit competitors, send replies, or change settings.
Is it scoped to my organization?
Yes. Each key resolves to exactly one organization and every tool runs inside that scope. A key never sees another organization's data.
How is access secured?
OAuth sign-in with standard discovery, or bearer keys you generate, name, and revoke from Settings. Revoking a key cuts access immediately.
Which plans include MCP?
Tool calls draw from the same usage credits as Sendsitive AI, so any plan with a credit allowance can connect: Pro and Business include one, and other plans can purchase credits. It works with any MCP-compatible client: Claude Desktop and web connectors, ChatGPT, OpenAI Codex, Cursor, Zed, or your own agents.
