Why Gemini

What Gemini does with your Apollo.io data

Ground Gemini in your real data

Gemini with Sequel fetches live data from your databases before answering. Every number in the response is pulled from your actual data — not estimated or hallucinated.

Multi-modal analysis

Combine Gemini's multi-modal reasoning with Sequel's data access. Ask Gemini to analyze trends in your database data and produce a written summary, chart description, or presentation outline.

Build grounded AI apps faster

Developers building on the Gemini API can use Sequel as a data-access tool, giving their apps real-time database access without building custom integrations for every data source.

Configuration

Add Sequel to Gemini

Place this in Google AI Studio or Gemini API and replace sql_your_api_key with a key from Settings → API Keys.

Google AI Studio or Gemini API

}

Install

Install Apollo.io MCP in Gemini

Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.

Already have an MCP client?

https://api.sequel.sh/mcp

Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client

Frequently asked questions

How do I connect Apollo.io to Gemini?

You need two things: (1) connect Apollo.io to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Gemini using the setup shown above. Once both are done, Gemini can query your Apollo.io data directly.

What Apollo.io data can Gemini access?

Gemini can access any data available through your Apollo.io connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.

Is my Apollo.io data sent to Gemini's servers?

Query results are returned to Gemini as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.

Do I need a Sequel account?

Yes. You need a Sequel account to connect Apollo.io and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Apollo.io and generate an API key from Settings → API Keys.

Can I connect multiple Apollo.io accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Apollo.io accounts or properties, add each as a separate connection in Sequel. Gemini will be able to query all of them.

How do I connect Gemini to Sequel?

Gemini's MCP support is available through Google AI Studio and the Gemini API. In AI Studio, go to Settings → Extensions and add the Sequel MCP server URL. For the API, include the MCP server in your tool_config as shown above.

Which Gemini models support MCP?

MCP tool use is supported on Gemini 1.5 Pro, Gemini 2.0 Flash, and newer models. Check Google's latest documentation for the current list of models with MCP/tool use support.

Can I use Sequel with Gemini in Google Workspace?

Gemini for Google Workspace (Docs, Sheets, Gmail) has a different extension model. Sequel MCP currently targets the Gemini API and AI Studio. Enterprise Workspace integrations may be available in future.

Is this suitable for building production apps with Gemini?

Yes. You can use Sequel MCP in Gemini API applications by passing it as a tool. This is ideal for building internal tools, dashboards, or customer-facing AI features that need real database access.

How do I connect Apollo.io to Sequel?

Create a master API key in Apollo under Settings → Integrations → API → Create New Key, enable master access, then paste the key into Sequel's Apollo connector and click Test. The People and Organization search endpoints require a master key.

Does Sequel consume my Apollo credits?

Only when you search Apollo's global database. The 'Search People' and 'Search Organizations' tools query Apollo's full prospect/company database and consume credits per Apollo's pricing. The 'Search Contacts' and 'Search Accounts' tools read your own saved CRM data and consume no credits.

Can Sequel change anything in Apollo?

No. The connector ships read-only search tools only — it cannot create, update, or delete contacts, accounts, sequences, or any other Apollo record.

Does Apollo's People Search return email addresses?

No. Apollo's people-search endpoint intentionally omits email addresses and phone numbers; obtaining those requires Apollo's separate enrichment endpoints, which this connector does not expose.
