MCP Overview
What the Icebreaker MCP server exposes, which use cases it's built for, and when to use MCP vs the REST API.
The Icebreaker MCP server makes your professional network available as a set of tools inside any AI assistant that supports the Model Context Protocol. It works with Claude, ChatGPT, Cursor, and others.
Instead of switching between tabs, building exports, or annotating spreadsheets, you can search and act on your network using natural language, right inside the tools you're already working in.
"Find senior iOS engineers in my network in Austin"
"Who can intro me to the Head of Engineering at Vercel?"
"Search our team's network for web3 founders who've raised a seed round"What you can do
Search your network
Search across your synced LinkedIn, GitHub, and X/Twitter connections by role, skill, location, or company. Searches are scoped to your extended network (1st and 2nd degree) by default, so results are people you can actually reach.
Find warm intros
For any person in Icebreaker, the server can surface who in your network knows them and rank those connectors by signal score, giving you the strongest path to a warm introduction.
See mutual connections
Quickly surface shared connections between you and a target profile. Useful for validating a candidate, preparing for a meeting, or understanding your relationship surface before an outreach.
Search your team's combined network (Teams)
On every plan, including Free with its 2 seats, you can search your whole team's combined LinkedIn, GitHub, and X/Twitter connections in a single query. One search covers everyone's connections, not just your own.
Manage contact lists
Create, update, and query saved contact lists. Useful for tracking candidates across a search, building target account lists, or maintaining a pipeline of warm prospects.
Sync and enrich
Queue a LinkedIn, GitHub, or X/Twitter graph sync, inspect queue status and aggregate counts, or cancel a pending sync you requested or queued. Queueing is not completion. Enrich individual people and companies by LinkedIn URL to pull contact information, job titles, and firmographic data.
Individuals and teams
The MCP server is available on every plan, including Free. By default it searches your own network: your 1st and 2nd degree connections on LinkedIn, X, and GitHub.
Some tools need a Starter plan or higher: the ranked intro path lookup, lists, and enrichment. If you are on a paid team, your AI tool runs these against your team. If a tool needs a paid plan, the server says so and lists any teams you can use instead. See icebreaker.xyz/plans for current plans.
If your results look thin, connect more accounts at app.icebreaker.xyz/settings/linked-accounts.
MCP vs REST API
Icebreaker exposes two integration surfaces. Here's when to use each:
| MCP | REST API | |
|---|---|---|
| Best for | Conversational and agentic workflows | Programmatic integrations and custom apps |
| How you call it | Natural language via an AI assistant | HTTP requests from your code |
| Auth | OAuth (per user) | Bearer token (contact [email protected]) |
| Typical use | "Find engineers at Coinbase in my network" from Claude | Pulling profile data into your own product |
| Requires AI client | Yes | No |
Use the MCP server if you're working inside Claude, ChatGPT, or Cursor and want to interact with your network conversationally or as part of an agent workflow. Use the REST API if you're building a product or pipeline that calls Icebreaker programmatically.

For full parameter documentation and examples, see Available Tools.
Data and permissions
The MCP server only accesses data you've synced to your Icebreaker account. It cannot read connections you haven't synced, and it operates entirely within your account's visibility settings.
When you connect via OAuth, you authorize the server to act on your behalf. No data is shared with third parties. For details on what the OAuth flow requests, see OAuth.
