LeanConnect

Put your agents to work in every app.

LeanConnect lets agents act in the tools your team already uses, from CRM, support and messaging to files, databases and developer tools, plus the open web and your own MCP servers, all through one governed gateway. Credentials are encrypted and never reach the model, and sensitive actions wait for a person to approve them.

01

Credentials never touch the model

Keys are encrypted at rest and applied at call time. Agents get results, never secrets.

02

People approve what matters

Let reads flow, hold writes for approval and switch off anything destructive, per connector and per function.

03

Bring any MCP server

Register a remote MCP server and govern and meter it like a built-in connector.

Capabilities

What your agents can do with LeanConnect.

Web search

Ranked results from the open web, delivered as clean, agent-ready data.

Email

Send transactional email from your agents, with HTML and attachments.

A catalogue of apps

CRM, support, messaging, projects, files, data and commerce, each with typed actions your agents call as MCP tools.

Any MCP server

Add your own MCP servers under the same keys, limits and approvals.

Approvals for writes

Hold sensitive actions until a teammate approves them in the console.

Encrypted credentials

Store keys and tokens once; they are encrypted at rest and never exposed to the model.

How your agent uses it

Native MCP tools, governed.

Every connector action appears in your agent's tool list the moment you switch it on, with the same approvals, limits and activity log as the rest of LeanTools.

Questions

Everything you need to know.

Something else on your mind? Talk to us.

How many connectors are available?

112 connectors with 540+ actions between them, from CRM and support to files, data and developer tools, alongside web search and email. Any remote MCP server can join them.

What if the app we need is not listed?

Register its MCP server and govern it like a built-in connector today, or tell us which app you need.

Do agents ever see our credentials?

No. Credentials are encrypted at rest and applied at call time. Agents receive results, never secrets.

Can a person approve actions first?

Yes. Require approval for writes and the call waits for a teammate's decision in the console. Requests that nobody decides expire after 30 minutes.

What does an action cost?

Each completed action draws a small per-connector price. Refused, failed and timed-out actions are free.
