MCP clients
Connect Ken to Cline with MCP
Cline connects to Ken's remote MCP server over Streamable HTTP. Add Ken as a remote server with type streamableHttp, Ken's server URL and your Ken API key as a Bearer header. The Cline CLI can sign in with OAuth instead.
How Do You Connect Ken to Cline?
In short Add https://mcp.ken.so/mcp as a remote MCP server in Cline with your Ken API key as a Bearer header.
Create a Ken API Key
In the Ken app, go to Settings > Integrations > API Keys and create a key for Cline.
Open Cline's MCP Settings
Select the MCP Servers icon in the top toolbar of the Cline panel, open the Configure tab, then select Configure MCP Servers to open cline_mcp_settings.json.
Add Ken as a Streamable HTTP Server
Paste this entry under mcpServers with your key and save. Set type to streamableHttp: without it, Cline falls back to the legacy SSE transport.
{ "mcpServers": { "ken": { "type": "streamableHttp", "url": "https://mcp.ken.so/mcp", "headers": { "Authorization": "Bearer <KEN_API_KEY>" }, "disabled": false, "autoApprove": [] } } }Check That Ken's Tools Load
Ken appears in the MCP Servers list with its tools. Ask Cline something Ken can answer to test it.
What Can You Ask Ken From Cline?
In short Ask in plain language. The client picks the Ken tool, and Ken runs it with your workspace role.
| Ask | Ken tool used | What the tool does |
|---|---|---|
| Find VPs of Sales at US software companies with 50 to 200 employees. | search_read | Searches Ken's people and company database and returns filter facets. |
| Load Ken's campaign-planning skill and plan a 3-step cold email campaign for that list. | load_skill | Loads one Ken workflow skill, such as campaign-planning, into the chat. |
| Before I launch, preview who lands in the Series B segment. | segments_read | Previews which contacts land in a campaign segment. |
| Which of my campaigns are running right now? | campaigns_read | Lists campaigns and reads one campaign's settings and status. |
| How did my campaigns do this week? Show sends, replies and bounces for each one. | analytics_read | Reads campaign performance, engagement, deliverability and reply classifications. |
Admins and members get read and write tools. View-only members get read tools plus inbox replies.
What If Ken Does Not Connect in Cline?
In short Most failures come from a skipped sign-in step or a client setting.
| Problem | Fix |
|---|---|
| Ken connects over SSE and fails | Add "type": "streamableHttp" to the ken entry. Cline treats an entry without a type as legacy SSE. |
| Ken's tools time out | Raise the MCP timeout in Cline's MCP settings and try again. You can restart an unresponsive server from the same screen. |
| Ken answers 401 with an API key | The key was revoked or mistyped. Create a new one in the Ken app under Settings > Integrations > API Keys. |
Frequently Asked Questions
Can Cline sign in to Ken with OAuth instead of an API key?
The Cline CLI can. Run cline mcp add ken https://mcp.ken.so/mcp --transport http --yes, then run cline mcp and choose Authorize OAuth. Cline's docs do not describe OAuth for the IDE extension, so use an API key there.
How do I add Ken from the Cline CLI with a key?
Run cline mcp add ken https://mcp.ken.so/mcp --transport http --header "Authorization: Bearer <KEN_API_KEY>" --yes.
Should I auto-approve Ken's tools in Cline?
Only read tools such as search_read and campaigns_read. Leave write tools like campaigns_write out of autoApprove so Cline asks before it changes a campaign.
What can Cline change in my Ken workspace?
Only what your Ken role allows. Admins and members get read and write tools, including campaign launches. View-only members get read tools plus inbox replies. Ken checks your role on every call, so a role change applies right away.
The new Ken opens to the waiting list in batches.
