About MCP

What is the MCP server?

MCP (Model Context Protocol) is an open standard that lets an AI assistant connect to outside tools and data. Our MCP server is one of those connections. Once you add it to your AI tool, you can ask questions in plain English and the assistant pulls live data from Multiples directly into your chat.

In Claude and ChatGPT, Multiples is a published listing: install it from the Claude Connectors Directory or the ChatGPT plugin directory, sign in with your Multiples account, and you're done. No key, config file or developer mode. The Claude connector also carries over to Claude Code, and the ChatGPT plugin to Codex.

A little more technically: it's a remote server your AI client talks to over HTTPS. Other developer tools like Cursor and VS Code connect to the same server with an MCP key. Either way, your assistant can then call our data tools on your behalf and write the answer.

What you can do with it

Ask your AI assistant the kind of questions you'd normally research by hand. For example:

“What were the largest cybersecurity M&A deals in 2026?”
“Compare EV/Revenue multiples for the biggest public semiconductor companies.”
“Who were the most active fintech investors over the last two years?”
“Show me Anthropic valuation history”

Your assistant picks the right tool, fetches data, and writes the answer into the workflow you're already in.

What you'll need

An active Multiples Pro Max subscription
Claude or ChatGPT (including Claude Code and Codex), where you install Multiples from the store, or a developer tool that connects to remote MCP servers (Cursor, VS Code and similar) plus an MCP key

Quick start

Step 1

Install Multiples in Claude or ChatGPT

Open the Multiples listing directly, or search for Multiples in Claude (Customize → Connectors) or ChatGPT (Plugins).

Open in the Claude Connectors Directory

Open in the ChatGPT plugin directory

Using Cursor or VS Code instead? Generate a key in Account → MCP and follow the .

Step 2

Sign in with your Multiples account

Click Connect (in ChatGPT, Install plugin first), sign in to Multiples and approve. No key or config needed.

Step 3

Ask a question

Start a chat in your AI tool and verify it works by asking something like “Using Multiples.vc, what were the ten biggest SaaS acquisitions of 2026?”

Connect your AI tool

In Claude and ChatGPT, install Multiples from the Claude Connectors Directory or the ChatGPT plugin directory and sign in. Other developer tools connect to the server URL below with an MCP key from your account. If your tool isn't listed here, check its docs for how to add a remote MCP server.

Claude

Official listing

Open in the Claude Connectors Directory

Open the Multiples listing in the Claude Connectors Directory (button above), or in Claude go to Customize → Connectors → + → Browse connectors and search for "Multiples".
Click Connect, sign in with your Multiples account, and approve.
Start a chat and ask away. Toggle Multiples per chat from the + → Connectors menu.

No key or config file needed. One connection covers claude.ai, Claude Desktop, the mobile apps, Cowork, and Claude Code when signed in with the same Claude account.

ChatGPT

Official listing

Open in the ChatGPT plugin directory

Open the Multiples.vc listing in the ChatGPT plugin directory (button above), or in ChatGPT go to Plugins in the sidebar (or Settings → Plugins) and search for "Multiples".
Click Install plugin, then Connect, sign in with your Multiples account, and approve.
Start a new chat and @mention Multiples.vc, or pick it from + → More.

No developer mode or key needed. The same plugin also works in Codex. If you still see Apps instead of Plugins, the listing is under Apps.

Claude Code (CLI)

Use your Claude connector (recommended)

Connect Multiples in Claude first (see the Claude setup).
Sign in to Claude Code with the same claude.ai account. Multiples loads automatically; run /mcp to check it is connected.

Or add it with a key

Run the command below (replace the key) — or add the same server to your project’s .mcp.json.

Replace mpl_mcp_YOUR_KEY with a key from your multiples.vc account.

claude mcp add multiples-vc --transport http --header "Authorization: Bearer mpl_mcp_YOUR_KEY" https://multiples.vc/api/mcp-server/mcp

Use this if you sign in to Claude Code with an API key or a third-party provider, since those don’t load claude.ai connectors.

Cursor

Open File → Preferences → Cursor Settings.
Go to MCP (under Customize → MCPs) and choose "Add a Custom MCP Server" — this opens ~/.cursor/mcp.json.
Paste the block below, replace the key, and save.
The "multiples-vc" server appears with its tools enabled.

Replace mpl_mcp_YOUR_KEY with a key from your multiples.vc account.

{
  "mcpServers": {
    "multiples-vc": {
      "type": "http",
      "url": "https://multiples.vc/api/mcp-server/mcp",
      "headers": {
        "Authorization": "Bearer mpl_mcp_YOUR_KEY"
      }
    }
  }
}

VS Code

Open the Command Palette (Ctrl/Cmd+Shift+P) and run "MCP: Open User Configuration" (or "MCP: Add Server").
Add the block below. VS Code uses a "servers" key (not "mcpServers"). Put it in .vscode/mcp.json for one workspace, or your user config to use it everywhere.
Replace the key and save; the "multiples-vc" server starts and its tools show up in agent mode.

Replace mpl_mcp_YOUR_KEY with a key from your multiples.vc account.

{
  "servers": {
    "multiples-vc": {
      "type": "http",
      "url": "https://multiples.vc/api/mcp-server/mcp",
      "headers": {
        "Authorization": "Bearer mpl_mcp_YOUR_KEY"
      }
    }
  }
}

MCP needs a recent VS Code with agent mode (GitHub Copilot) enabled. If you don’t see the "MCP:" commands, update VS Code and turn on agent mode.

How it works

MCP tools

When you ask a question, your AI assistant decides which of MCP tools to call and returns an answer:

Search

multiples_search_ma_deals — Find M&A deals by target, buyer, sector, geography, date, deal size or valuation multiple.
multiples_search_funding_rounds — Find VC funding rounds by company, sector, stage, geography or date.
multiples_search_public_companies — Screen listed companies by sector and valuation multiples — EV/Revenue, P/E, growth, margins and more.
multiples_search_companies_by_name — Look up one or more companies by name. Usually the first step, so later tools can reference them.
multiples_search_top_companies — Rank the largest companies — public or private — by valuation within a sector.

Rankings

multiples_search_buyer_rankings — The most acquisitive buyers in a sector, period, geography etc.
multiples_search_investor_rankings — The most active (or top lead) investors in a sector, period, geography etc.
multiples_search_sector_rankings — The hottest sectors, themes or geographies by deal activity.

Statistics

multiples_compute_deal_stats — Aggregate statistics — median, quartiles, mean, count — over a filtered set of deals, optionally bucketed by year or quarter.

Time series

multiples_get_time_series_stats — A monthly evolution of metrics over time for public companies.
multiples_get_time_series_aggregate — Peer-group median and quartiles for a metric over time across a set of public comps.
multiples_get_time_series_snapshot — Point-in-time values for several metrics across public companies, on a chosen month.

Reference

multiples_list_taxonomy_values — Browse or match the available filter values — sectors, themes, geographies, deal types and so on.

Good to know

Read-only: The server only reads data, it never changes anything in your account.
Curated results: Tools return a focused set of rows so answers stay fast and readable. When there is more to look at, the assistant includes a link into the full grid.
Fair-use limits: Usage is rate-limited per user to keep the service responsive. Normal research won't hit the limit.
Your subscription: MCP access follows your plan. If your Pro Max subscription becomes inactive, MCP access pauses.

Troubleshooting

I can't install Multiples in Claude or ChatGPT

Open the listing directly from the Claude Connectors Directory or the ChatGPT plugin directory. On Claude Team or Enterprise, only an admin can add connectors (Organization settings → Connectors). In ChatGPT, a greyed-out Connect button or “Disabled by admin” means your workspace admin needs to enable the app, or it isn't available on your plan or in your region yet.

Sign-in works but the tools are unavailable

MCP access needs an active Pro Max plan. Check your plan, then disconnect and reconnect Multiples from your AI tool's connector or app settings.

My developer tool says “unauthorized”

Check that the key is copied correctly (including the mpl_mcp_ prefix), hasn't expired or been revoked, and that your plan is Pro Max. Generating a fresh key and reconnecting usually fixes it.

My developer tool doesn't show any tools

Make sure the server URL and the Authorization header are both set, then reconnect or restart your client.
