API and MCP access come with every BLIX account · sign in with Google · checked October 10, 2026

Setup in four steps

1. Create your BLIX account (sign in with Google) and open Developers: your session is shown there.
2. Download the connector and add it to your client, with your session in BLIX_SESSION:

   Download the connector

   # 1. download the connector (one file, no dependencies; needs Node 20+)
   curl -O https://blixvip.com/_pub/blix-mcp.mjs
   # 2. sign in to BLIX, open https://blixvip.com/developers and copy your session

   Claude Code

   claude mcp add blix -e BLIX_SESSION=<from your Developers page> -- node /path/to/blix-mcp.mjs

   Claude Desktop, Cursor, Windsurf, Cline (JSON)

   {
     "mcpServers": {
       "blix": {
         "command": "node",
         "args": [
           "/path/to/blix-mcp.mjs"
         ],
         "env": {
           "BLIX_SESSION": "<from your Developers page>"
         }
       }
     }
   }

   Codex

   [mcp_servers.blix]
   command = "node"
   args = ["/path/to/blix-mcp.mjs"]
   
   [mcp_servers.blix.env]
   BLIX_SESSION = "<from your Developers page>"

   Gemini CLI (~/.gemini/settings.json)

   {
     "mcpServers": {
       "blix": {
         "command": "node",
         "args": [
           "/path/to/blix-mcp.mjs"
         ],
         "env": {
           "BLIX_SESSION": "<from your Developers page>"
         },
         "timeout": 15000
       }
     }
   }

   VS Code (.vscode/mcp.json)

   {
     "servers": {
       "blix": {
         "type": "stdio",
         "command": "node",
         "args": [
           "/path/to/blix-mcp.mjs"
         ],
         "env": {
           "BLIX_SESSION": "<from your Developers page>"
         }
       }
     }
   }

3. Check the tools are listed. Claude Code: /mcp. Gemini CLI: /mcp. Cursor: Settings → MCP shows blix with 20 tools.
4. Ask. "What is in the final stretch on pump.fun right now? For the top three, show holders and whether the dev sold, and quote a 0.3 SOL buy."

ChatGPT: the remote-only case

ChatGPT's web app connects to remote (HTTPS) MCP servers through Developer Mode, not to local stdio servers, and plan eligibility has changed through 2026. OpenAI's Codex CLI does start local servers, so the quickest route to GPT is Codex with the config above. To reach the ChatGPT web app, put the connector behind a stdio-to-HTTP bridge on a machine you control, with HTTPS and authentication, and add the URL as a custom connector. The ChatGPT page has the details.

Keep keys away from the model

The connector has no wallet and no key; the only writes are the paper desk. That is deliberate: an agent that can read everything and spend nothing is the right shape for memecoins. Real trades are made by you, in the terminal, in one click.

What to ask, by job

Troubleshooting

• "Your BLIX session is missing or expired": sign in again, open Developers and copy the fresh session into BLIX_SESSION.
• The client does not list the server: check the path to blix-mcp.mjs (on Windows, escape backslashes in JSON) and that node (20+) is on the PATH the client uses.
• Tool results look truncated: by design: lists are capped (limit, default 10, max 50) and picture fields dropped so a model is not flooded.
• Anything else: the Discord.

The BLIX community

Every account comes with the BLIX Discord: the people trading on the terminal, the narratives as they form, feature drops before they are announced, and the team answering questions. Join the Discord once you have signed up.
