Give Claude live LinkedIn data

Add the Flux connector once and Claude can read any public profile’s posts, search a topic semantically, and walk the engagement graph — inside the conversation you’re already having.

Connector URL: https://fluxgraph.app/mcp· auth: bearer API key

Setup · 60 seconds

Three steps, one endpoint.

Flux exposes a single Streamable-HTTP MCP endpoint at https://fluxgraph.app/mcp. Auth is a bearer token — one API key per user.

  1. 1

    Generate an API key

    Log in and open Settings → MCP, then click Generate MCP key. The key is shown exactly once — copy it straight into your client config. Keys start with flux_ and you can revoke and regenerate at any time.

  2. 2

    Add Flux to your client

    Claude Code — one command, replacing YOUR_API_KEY:

    terminal
    claude mcp add --transport http --scope user flux \
  https://fluxgraph.app/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

    Claude Desktop — edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

    claude_desktop_config.json
    {
  "mcpServers": {
    "flux": {
      "type": "http",
      "url": "https://fluxgraph.app/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

    Cursor, Zed, or anything that reads .mcp.json — drop the same block at your project root or in the client’s MCP config directory:

    .mcp.json
    {
  "mcpServers": {
    "flux": {
      "type": "http",
      "url": "https://fluxgraph.app/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
  3. 3

    Restart and try it

    Fully quit and relaunch Claude Desktop — it picks up MCP servers on boot. Claude Code picks it up on the next session. Then ask: “List my tracked LinkedIn profiles.” Claude calls list_profiles. If that answers, all 63 tools are live.

Three things to ask first

Real questions, in customers’ words.

Swap the placeholder for a LinkedIn profile or post URL and these run exactly as written.

“What are the top performing posts of <person> so I can study their content?”

Claude pulls their recent posts live, ranks them by engagement, and reads the text back so you can see the pattern rather than the leaderboard. Paste their LinkedIn profile URL in place of the placeholder.

linkedin_profile_postsget_posts

“What has <person> been paying attention to lately?”

Their reactions and comments — what they read and reply to. Usually a sharper signal than what they publish, and the fastest way into a warm conversation.

linkedin_profile_reactionslinkedin_profile_comments

“Who engaged with this post and which of them work at target accounts?”

Claude fetches the reactors and commenters, groups them by current employer, and surfaces the ones who are employees or alumni of the accounts you name.

Troubleshooting

When it doesn’t connect.

Does this work in claude.ai in the browser?
Not yet. Claude’s browser connector directory expects a remote server that speaks OAuth; Flux authenticates with a bearer API key, which the web form has no field for. Claude Code, Claude Desktop, Cursor, and Zed all let you set the header directly, so use one of those. OAuth support is on the roadmap — tell us if you want it and it moves up.
Claude says it can’t find the Flux tools.
Fully quit and relaunch Claude Desktop — closing the window is not enough; it reads MCP servers on boot. Then check the config file is valid JSON. In Claude Code, run claude mcp list to confirm flux is registered and connected.
I get a 401.
The key is missing, malformed, or revoked. Keys start with flux_ and the header must read Authorization: Bearer flux_…. Generate a fresh one from Settings → MCP.
I get a 402 insufficient_credits.
A tool you asked for reaches LinkedIn live and your credit balance is too low. Ask Claude to run get_credit_balance to see where you stand, or get_cost_estimate before anything expensive.
Does Claude see other people’s Flux data?
No. Your API key scopes every request to your own account. Public LinkedIn lookups are the only data that comes from outside it.

Not on Claude?

The same endpoint works from OpenAI’s Codex CLI, and from anything else that speaks MCP over HTTP with a custom header.

MCP access is on Edge — $15/month or $150/year, including all 63 tools and the dashboard.
