What the LinkDeal MCP server does

The LinkDeal MCP server gives an MCP-compatible AI agent access to lead discovery based on LinkedIn engagement. Searches can target reactions to posts at a company domain, reactions to posts about a keyword during the current week, or an ideal-customer description expressed in natural language.

After finding leads, the agent can unlock business email addresses and phone numbers, inspect a lead's own recent posts ordered by engagement, or unlock top commenters on a post that the lead reacted to. These capabilities provide contact and outreach context without requiring a separate workflow for each lookup.

Slack delivery is built in. Specific leads or every lead returned by a search can be sent to a configured Slack channel. The server also exposes tools for saving and retrieving searches, checking credits, reviewing plan details, topping up credits, and changing subscription status.

How it works

The service is exposed at https://app.linkdeal.ai/api/mcp over stateless HTTP with Server-Sent Events. Authentication can use OAuth 2.0, including dynamic client registration, or a bearer token in the Authorization header. OAuth is the recommended route and uses a LinkDeal account; API keys are generated in LinkDeal Settings and begin with ld_.

An agent can turn a request such as finding leads at a company domain or locating a particular role in a market into one of the search calls. Credit usage depends on the operation: pipeline searches charge five credits per post scanned, semantic ICP searches charge five credits, contact enrichment charges 15 credits per lead, recent-post unlocks charge five credits per lead, and comment unlocks charge 10 credits per lead.

Setup and configuration

For the LinkDeal MCP server, OAuth setup uses the remote MCP URL in a supported client's connector or MCP settings, followed by LinkDeal sign-in. The documented OAuth clients are Claude.ai or Claude Desktop, Cursor, and ChatGPT.

API-key setup requires creating a key in LinkDeal Settings and supplying it as a bearer token. Claude Desktop can connect through mcp-remote with the remote URL and an Authorization header. Cursor and Codex can use the URL and header directly in their MCP configuration. No server-side environment variables are documented.

Slack delivery requires a webhook URL saved through setup_slack_webhook. The saved webhook can later be removed with disconnect_slack_webhook.
