Flux LinkedIn MCP server

Flux (fluxgraph.app) is a hosted MCP server for LinkedIn intelligence. Connect it to Claude, Cursor, or another MCP client, then ask about the posts and engagement of any public LinkedIn profile or company page.

https://www.fluxgraph.app/mcp

This repository holds documentation and an agent skill. The server itself is hosted and closed source, so there is nothing to install or run.

If your client needs a local command instead of a remote URL, the flux-linkedin-mcp npm package wraps the hosted endpoint over stdio:

{
  "mcpServers": {
    "flux-linkedin": {
      "command": "npx",
      "args": ["-y", "flux-linkedin-mcp"]
    }
  }
}

The package source is in npm/.

What it does

• Audit posting patterns. Find which days, hours, formats, and lengths beat an account's own baseline, with the sample size behind each finding.

• Research any public account. Use it on your own profile, a client's, a prospect's, or a competitor's.

• Search and track over time (paid). Paid plans add full post history, weekly refresh, trends over time, search, and the engagement graph.

Flux is read-only on LinkedIn. It cannot publish, like, comment, connect, or message.

Where the data comes from

Flux reads public LinkedIn data through a third-party data provider. It does not use an official LinkedIn API, and it is not affiliated with or endorsed by LinkedIn. You do not give Flux a LinkedIn password or cookie, and nothing runs under your LinkedIn account.

Flux has no impressions, profile viewers, or other private data. LinkedIn's User Agreement restricts automated data collection, so please decide whether this approach fits your own use.

The free preview

Two tools offer a free preview of a public profile or company page:

Things to know:

• Previews cover at most 50 posts and are pulled once per profile, so check last_pull_at to see how old the data is.

• Hours and days are in UTC.

• Usage limits apply. A signed-in account can pull one new profile per day; profiles Flux already holds are free to look at.

Connect it

Claude (web, desktop, mobile). Open Settings → Connectors → Add custom connector, name it Flux, and paste the URL above. Choose Sign in when needed and Register automatically.

Claude Code

claude mcp add --transport http --scope user flux https://www.fluxgraph.app/mcp

Cursor and other clients that read mcpServers

{
  "mcpServers": {
    "flux": {
      "type": "http",
      "url": "https://www.fluxgraph.app/mcp"
    }
  }
}

For account tools in developer clients, generate a key under Settings → MCP → Developer setups in Flux, then send it as an Authorization: Bearer YOUR_KEY header. Tools outside the preview need a sign-in or a key, and most need a paid plan. See the setup guide and tool reference.

Then try a prompt like this:

Use Flux to preview linkedin.com/in/janedoe. Which days, hours, formats, and lengths beat this account's own baseline, and how many posts back each finding?

The skill

skills/linkedin-mcp-posting-audit teaches an agent to run that audit carefully. It labels thin samples as anecdotes, reports how old the data is, avoids claims about reach, and ends with one specific test to run. It also works on pasted posts if you would rather not make a network call.

To use it, copy the folder into your agent's skills directory (for Claude Code, ~/.claude/skills/).
