## Connect Crunchbase in Elaichi

This happens once for the organization, before any client is involved.

1. Open Connections, choose Add connection, and pick Crunchbase.
2. Optionally set Share with, then press Connect.
3. Paste a Crunchbase API key. One person generates a token in Crunchbase and pastes it once. Everyone else works through Share with, and never sees it.

Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which Crunchbase tools are exposed, rename them, or freeze arguments before anyone points a client at it.

## Connect Crunchbase to Claude

Endpoint: https://api.elaichi.ai/mcp

1. Open Customize, then Connectors.
2. Press Add.
3. Name it, paste the MCP server URL, then Continue.
4. Sign in and approve.

On Team and Enterprise, an Owner adds it once. Everyone else turns it on for themselves.

## Connect Crunchbase to ChatGPT

Endpoint: https://api.elaichi.ai/mcp

1. Open Plugins, then press the + button.
2. Name it and paste the endpoint into Server URL.
3. Leave Authentication on OAuth, then tick the risk acknowledgement.
4. Press Create, then sign in and approve.

Works on the web today. The plugin directory lives at chatgpt.com/plugins.

## Connect Crunchbase to Cursor

Endpoint: https://api.elaichi.ai/mcp

1. Open `~/.cursor/mcp.json`.
2. Add the endpoint under `mcpServers`.
3. Reload Cursor, then sign in and approve.

Set up per machine, so repeat it on each computer you work from.

## Connect Crunchbase to any MCP client

Endpoint: https://api.elaichi.ai/mcp

1. Add the endpoint as a remote MCP server.
2. Sign in and approve.

The Elaichi Agent already has these tools, with nothing to set up.

## What the consent screen decides

Only Read is granted by default, which is not enough to call a Crunchbase tool. Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone.

## What teams do with Crunchbase through Elaichi

### Qualify a prospect before the first call

Sales. Ask for a company's Crunchbase profile, its latest funding round, headcount range and who invested, and walk into the call knowing whether they have budget and momentum.

### Build a target list from recent raises

Business development. Pull every company in a sector that closed a Series A or B in the last quarter, with investors and locations, and hand the list to the team the same morning.

### Spot companies to feature or partner with

Marketing. Search Crunchbase for organizations that just announced funding or an IPO and draft outreach while the news is still fresh.

### Map who owns what before a deal

Corporate development. Look up ownership records, funding history and investors for an acquisition target and get a one-page summary without opening a dozen Crunchbase tabs.

### Compare competitors on funding and growth

Research. Line up several companies side by side on total raised, last round, founding year and key people, and turn it into a short brief for leadership.

### Find who is speaking at an event

Partnerships. Check which companies and people appear at an upcoming conference in Crunchbase and prepare a shortlist of who to meet there.

## Frequently asked questions

### How do I connect Crunchbase to Claude?

Connect Crunchbase in Elaichi first, then in Claude go to Customize, then Connectors, then Add, and paste the endpoint https://api.elaichi.ai/mcp. Crunchbase's own sign-in step is pasting the API key from your Crunchbase account into Elaichi, which takes a minute. There is no OAuth application to register and no client ID or secret to generate.

### Does Crunchbase work with ChatGPT and Cursor as well as Claude?

Yes. Once Crunchbase is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. You connect Crunchbase once and every client you use picks it up.

### What can an AI agent actually do with my Crunchbase data?

With Crunchbase connected, an agent can look up a company or person, pull funding rounds, investors, ownership, IPOs and event appearances, and search for companies that match a description such as a sector, location or recent raise. It then summarizes or compares what it finds in plain language. Because Crunchbase has many lookups, short concrete asks like "latest funding round for Acme" work better than long paragraphs.

### Does connecting Crunchbase give the AI everything in Crunchbase?

No. Every request runs under the Crunchbase API key of the person who signed in, so the agent sees exactly what that person's Crunchbase plan allows, no more. Elaichi can narrow that access further, for example to company lookups only, but it can never widen it beyond what Crunchbase itself grants.

### Can my team share one Crunchbase connection?

Yes. One person connects Crunchbase in Elaichi and shares it with a team, and nobody else ever handles the API key. Each teammate still signs in to Elaichi as themselves, so the audit log records who searched Crunchbase and when, even though they work through a shared connection.

### Can I stop an agent from deleting or changing things in Crunchbase?

The Crunchbase connector only reads records, so an agent cannot create, edit or delete anything in Crunchbase through it. You can still restrict individual actions, such as people searches, per team in Elaichi. A restricted action is never advertised to Claude, ChatGPT or Cursor, so no prompt can reach it.

### What happens to a Crunchbase connection when someone leaves?

Offboarding a person in Elaichi ends their access to Crunchbase through every client at once, whether they connected it themselves or used a shared connection. A shared Crunchbase connection keeps working for everyone else on the team. If you disconnect Crunchbase once in Elaichi, it disappears from Claude, ChatGPT, Cursor and every other client at the same time.
