Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http chainstack https://mcp.chainstack.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

    "chainstack": {
      "url": "https://mcp.chainstack.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Chainstack safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.12.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Chainstack MCP server

The Chainstack MCP server gives AI agents direct access to the Chainstack platform — deploy blockchain nodes, search documentation, and check platform status from any coding environment.

Live at [`mcp.chainstack.com`](https://mcp.chainstack.com)

Quick start

Type this into any AI agent:

get mcp.chainstack.com

The agent will fetch the onboarding page and walk you through setup. Works with Claude Code, Cursor, Codex, Windsurf, Gemini CLI, GitHub Copilot, Antigravity, Claude.ai, and ChatGPT.

Tools

No API key needed:

search_docs — search Chainstack documentation
get_doc_page — fetch full doc page content
get_platform_status — check platform status and incidents
contact_chainstack — send a message to Chainstack (sales, support, or general questions)
get_chainstack_pricing — live pricing snapshot: plan tiers, feature matrix, add-ons, and the per-chain dedicated-node catalog

API key required (get one here):

get_organization, list_projects, create_project, get_project, update_project, delete_project
list_nodes, get_node, create_node, update_node, delete_node, get_deployment_options
list_node_access_rules, create_node_access_rule, update_node_access_rule, delete_node_access_rule, set_node_access_rules_status — restrict a Global Node to allowed IP addresses or origins
request_testnet_funds — top up a testnet address from the Chainstack faucet (12 networks across EVM, Solana, and TON)

Two ways to use

Option 1: Install as a skill (lean context)

Cross-agent, via the skills CLI — it auto-detects your installed agent (50+ supported, including Claude Code, Cursor, Codex, Windsurf, Antigravity, GitHub Copilot, Pi, and OpenCode):

npx skills add chainstacklabs/mcp-server

This installs the bundled skills/chainstack skill.

Option 2: Register as an MCP server

VS Code — Chainstack is in the GitHub MCP Registry, so VS Code installs it for you. Two ways:

From inside VS Code — open the Extensions view (⇧⌘X / Ctrl+Shift+X), search @mcp chainstack, and click Install. Right-click and choose Install in Workspace to write .vscode/mcp.json instead of your user profile.
From the registry — open the Chainstack entry and click Install > Install in VS Code.

Neither needs an API key, which covers every tool that works unauthenticated.

Anywhere else:

claude mcp add --transport http chainstack https://mcp.chainstack.com/mcp -s user

See full setup guide for all agents.

MCP registries

Listed in both public registries as com.chainstack/chainstack:

GitHub MCP Registry — the catalog VS Code surfaces in its Extensions view, with one-click install
MCP Registry — the official registry that MCP clients read from

curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=com.chainstack/chainstack&version=latest"

server.json is the manifest. Its version field is a placeholder — the publish workflow derives the real value from the live server card at mcp.chainstack.com, which renders it from the deployed chart, so the registry entry cannot drift from what is actually running. Query the registry, not this file, to see what is published.
