listing.about

Connects an assistant to the Chainstack platform. You can list projects and nodes, create and delete them, look up valid blockchain and cloud deployment options, search the protocol and RPC documentation, check platform status, read live pricing, request testnet faucet funds, and send a message to the Chainstack team.

It runs as a hosted streamable HTTP endpoint at https://mcp.chainstack.com/mcp. Docs search, page fetch, platform status, pricing and contact tools work without a key. Node, project and faucet tools need a Chainstack API key sent as an Authorization Bearer header.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http chainstack https://mcp.chainstack.com/mcp --header "Authorization: Bearer <YOUR_API_KEY>"
  1. Replace the placeholder with your key before you run it, then check it with /mcp inside Claude Code.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Custom connectors can't send this server's key header, so use the mcp-remote bridge. Open Settings → Developer → Edit Config and add:
claude_desktop_config.json
{
  "mcpServers": {
    "chainstack": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.chainstack.com/mcp",
        "--header",
        "Authorization: Bearer <YOUR_API_KEY>"
      ]
    }
  }
}
  1. Replace the placeholder with your key and restart Claude Desktop.

The bridge needs Node.js on your computer.

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "chainstack": {
      "url": "https://mcp.chainstack.com/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}

VS Code

Add it to .vscode/mcp.json. VS Code asks for the key the first time and stores it securely:

.vscode/mcp.json
{
  "servers": {
    "chainstack": {
      "type": "http",
      "url": "https://mcp.chainstack.com/mcp",
      "headers": {
        "Authorization": "Bearer ${input:api-key}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "api-key",
      "description": "API key",
      "password": true
    }
  ]
}

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "chainstack": {
      "serverUrl": "https://mcp.chainstack.com/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}
  1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add chainstack --url https://mcp.chainstack.com/mcp --bearer-token-env-var CHAINSTACK_API_KEY

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.chainstack]
url = "https://mcp.chainstack.com/mcp"
bearer_token_env_var = "CHAINSTACK_API_KEY"

Set CHAINSTACK_API_KEY to your key in the shell that runs Codex.

Gemini CLI

gemini mcp add --transport http --header "Authorization: Bearer <YOUR_API_KEY>" chainstack https://mcp.chainstack.com/mcp

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI's settings file.

{
  "mcpServers": {
    "chainstack": {
      "type": "http",
      "url": "https://mcp.chainstack.com/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_API_KEY>"
      }
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.chainstack.com/mcp.

listing.faq

Can I paste mcp.tc/i/chainstack into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.chainstack.com/mcp, so your client talks to Chainstack directly. Your key goes there too, never to mcp.tc. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Chainstack need an API key or a sign-in?

Yes. Chainstack needs an API key, sent as the Authorization header. Get one from Chainstack and keep it in your client's config, never in a shared file.

Is Chainstack a remote or a local server?

Remote. Chainstack hosts it at https://mcp.chainstack.com/mcp, and it speaks Streamable HTTP. There's nothing to install.

What can Chainstack do?

It has 18 tools, including get_organization, get_deployment_options and list_projects. You can deploy, rename and delete blockchain nodes, create, update and delete projects that hold nodes and list valid blockchain, cloud and region options before deploying.

Which clients can use it?

Any client that supports remote MCP servers and can send your key: Claude Code, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others, and Claude Desktop through the mcp-remote bridge. claude.ai and ChatGPT can't send a key, so they can't use it.

Who wrote this page?

mcp.tc's robot read Chainstack's own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
