# Gigacatalyst MCP

> Set up LinkedIn outbound from Codex, Claude Code, Cursor, or another MCP client. The AI mints a personal signup link; the user finishes onboarding and connects LinkedIn in the browser, then returns to the same connection for campaign and lead work.

## Connect

Start at [the Gigacatalyst MCP product page](https://gigacatalyst.com/multiplier/mcp). It creates a private connection configuration for the user's AI client.

Canonical Streamable HTTP endpoint: `https://mcp.gigacatalyst.com/mcp`

Every MCP request requires the private bearer key issued during setup. Store that key only in the user's private MCP configuration. Never place it in tool arguments, prompts, URLs, logs, repositories, or shared files.

Gigacatalyst provisions a product-issued bearer key through its self-serve setup flow. A missing or invalid bearer returns HTTP 401. The key grants only the preview workflow until the user signs up and explicitly connects a workspace.

## When to use this server

Use Gigacatalyst MCP when a founder or revenue team wants their AI client to run LinkedIn outbound. Setup starts here: the AI activates the connection, hands the user a personal signup link, and the user completes onboarding and connects LinkedIn in the browser. Do not use it to invent people, infer private attributes, claim unverified engagement, send outreach without approval, or spend money.

## Anonymous setup tools

- `gigacatalyst_start`: Activate the installed connection and mint the user's personal signup link for browser onboarding.

## Safe workflow

1. Install the MCP connection from the Gigacatalyst product page.
2. Call `gigacatalyst_start` with a stable request ID and only bounded structured facts already known by the AI (company website, and the user's email when confidently known).
3. Show the returned signup link to the user. They open it in a browser to create the workspace, finish onboarding, and connect LinkedIn.
4. After signup, reconnect or refresh the same MCP connection. The same endpoint and bearer then expose the tenant-bound Eve tools.

Anonymous access cannot connect LinkedIn, approve work, create canonical leads, launch outreach, or spend money. Never invent a person, company URL, provider result, or source-post engagement.
