--- title: Quicknode MCP description: Manage Quicknode infrastructure through natural language using the official MCP server with any compatible AI assistant. tags: [] --- ## Overview > For the complete documentation index, see [llms.txt](/docs/llms.txt) The **Quicknode MCP server** connects your Quicknode account to MCP-compatible AI assistants like ChatGPT, Codex, Claude Code, Claude Desktop, Cursor, VS Code, and more. Once connected, you can create and manage endpoints, monitor usage, configure security settings, and review billing data through natural language instead of navigating the dashboard or writing API scripts. The server is hosted remotely at `https://mcp.quicknode.com/mcp` and authenticates via OAuth. It operates on top of Quicknode's [Admin API](/docs/admin-api), translating natural language instructions into API operations. The assistant interprets your request, selects the appropriate tool, and executes it after confirmation. TL;DR - Quicknode is an [official connector](https://claude.com/connectors/quicknode) in the **Anthropic MCP directory** — add it [directly](https://claude.ai/directory/connectors/356a8580-5936-40a0-9a06-5ab54bdaa344) or find it under **Customize** > **Connectors** in Claude - Quicknode is also available natively in **ChatGPT** and **Codex** — install directly from the [ChatGPT Apps catalog](https://chatgpt.com/apps/quicknode/asdk_app_69ca79775c848191a5f1e538e77aedbb) or via `/plugin` in Codex - All other clients (Cursor, VS Code, Windsurf, Zed) connect by pointing to `https://mcp.quicknode.com/mcp` and authorizing via OAuth - For CI/CD and non-interactive environments, skip OAuth and pass an API key directly — see [Using an API Key](#using-an-api-key) - Manage endpoints, monitor usage, configure security rules, and review billing through natural language, no dashboard or API scripts required ## Requirements - A [Quicknode account](https://www.quicknode.com/signup) - An MCP-compatible AI assistant (ChatGPT, Codex, Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Zed, or similar) ## Configuration Add the Quicknode MCP server to your assistant using the instructions for your client below. **Claude** #### Claude Web Quicknode is an [official connector](https://claude.com/connectors/quicknode) in the Anthropic MCP directory.

Add the following to your `settings.json`: ```json { "context_servers": { "quicknode": { "transport": "http", "url": "https://mcp.quicknode.com/mcp" } } } ``` 3. Restart Zed to activate the server **Other Clients** For any other MCP-compatible client, use the following connection details: - **URL:** `https://mcp.quicknode.com/mcp` - **Transport:** Streamable HTTP - **Authentication:** OAuth 2.1 (handled automatically on first connect) If your client doesn't support OAuth or HTTP transport natively, you can use `mcp-remote` as a bridge: ```json { "mcpServers": { "quicknode": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.quicknode.com/mcp"] } } } ``` ## Authentication and Roles When you connect for the first time, a browser window opens where you log in with your Quicknode account. If you belong to multiple Quicknode accounts, you'll choose which one to connect. You will then select an **API key role** that determines what the MCP server can do on your behalf: - **Admin** — Full read and write access. This allows your AI assistant to create and delete endpoints, modify security rules, update rate limits, and manage all account resources. - **Viewer** — Read-only access. Your assistant can list endpoints, view metrics, logs, usage, and billing data, but cannot create, modify, or delete any resources. This process creates an API key under the hood, scoped to the role you selected. You do not need to create or manage the key yourself. Choosing the Right Role Choose the **Viewer** role if you only need to inspect your infrastructure. Use **Admin** only when you need the assistant to make changes. If you need to switch roles later, remove the server from your client, re-add it, and go through the authorization flow again to re-authenticate with a different role. ## Using an API Key If you're running in a non-interactive environment where a browser-based login isn't possible (e.g., CI/CD pipelines, remote VMs, or automation agents), you can skip the OAuth flow by passing your API key as a bearer token. The MCP server recognizes the `Authorization` header and treats the request as already authenticated. Generate an API key from the [Quicknode Dashboard](https://dashboard.quicknode.com/api-keys) under **Account (_avatar icon_) > API Keys**. The role you assign to the key (Admin or Viewer) determines the MCP server's permissions, the same as choosing a role during the OAuth flow. **Claude** #### Claude Code Pass your API key as a bearer token using the `--header` flag: ```bash claude mcp add quicknode --transport http https://mcp.quicknode.com/mcp --header "Authorization: Bearer YOUR_API_KEY" ``` #### Claude Desktop Add the `--header` flag to the `mcp-remote` arguments in your `claude_desktop_config.json`: ```json { "mcpServers": { "quicknode": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.quicknode.com/mcp", "--header", "Authorization: Bearer YOUR_API_KEY"] } } } ``` **OpenAI** #### Codex Pass your API key as a bearer token using the `--bearer-token-env-var` flag, which tells Codex to read the key from an environment variable at runtime: ```bash codex mcp add quicknode \ --url https://mcp.quicknode.com/mcp \ --bearer-token-env-var YOUR_API_KEY ``` Run `codex mcp list` to confirm the server is registered. **Cursor** Add the following to your `.cursor/mcp.json`: ```json { "mcpServers": { "quicknode": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.quicknode.com/mcp", "--header", "Authorization: Bearer YOUR_API_KEY"] } } } ``` **VS Code** Add the `headers` field to your `.vscode/mcp.json`: ```json { "mcp": { "servers": { "quicknode": { "type": "http", "url": "https://mcp.quicknode.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } } } ``` **Windsurf** Add the `headers` field to your `~/.codeium/windsurf/mcp_config.json`: ```json { "mcpServers": { "quicknode": { "serverUrl": "https://mcp.quicknode.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } } ``` **Zed** Add the `headers` field to your `settings.json`: ```json { "context_servers": { "quicknode": { "transport": "http", "url": "https://mcp.quicknode.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } } ``` **Other Clients** For any client that supports custom headers, set: ```text Authorization: Bearer YOUR_API_KEY ``` If your client uses `mcp-remote`, add the `--header` flag: ```json { "mcpServers": { "quicknode": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.quicknode.com/mcp", "--header", "Authorization: Bearer YOUR_API_KEY"] } } } ``` ## Available Tools The MCP server exposes the following tools through the Admin API. Tools marked as **read-only** are available to both **Admin** and **Viewer** roles. All other tools require the **Admin** role. ### Endpoint Management Create, read, update, and delete Quicknode endpoints across any supported chain and network. | Tool | Description | Access | | --- | --- | --- | | list-endpoints | List all endpoints on your account | read-only | | get-endpoint | Get details for a specific endpoint | read-only | | create-endpoint | Create a new endpoint on a specified chain and network | admin | | delete-endpoint | Delete an endpoint | admin | | get-endpoint-metrics | Retrieve performance metrics for an endpoint | read-only | | list-endpoint-logs | Fetch recent logs for an endpoint | read-only | | get-endpoint-log-details | Get detailed information for a specific log entry | read-only | ### Rate Limits Configure method-level and endpoint-level rate limits. | Tool | Description | Access | | --- | --- | --- | | update-endpoint-rate-limits | Set overall rate limits (RPS, RPM, RPD) for an endpoint | admin | | list-endpoint-method-rate-limits | List method-specific rate limits | read-only | | create-endpoint-method-rate-limit | Add a rate limit for a specific RPC method | admin | | update-endpoint-method-rate-limit | Update an existing method rate limit | admin | | delete-endpoint-method-rate-limit | Remove a method rate limit | admin | ### Security Manage authentication and access control settings for endpoints. The `create-security-rule` and `delete-security-rule` tools support multiple rule types: IP allowlists, JWT validation, referrer restrictions, domain masks, and authentication tokens. | Tool | Description | Access | | --- | --- | --- | | list-endpoint-security | View current security settings and rules | read-only | | update-endpoint-security-options | Enable or disable security features (CORS, HSTS, IP filtering, etc.) | admin | | create-security-rule | Add a security rule (IP, JWT, referrer, domain mask, or token) | admin | | delete-security-rule | Remove a security rule | admin | ### Usage and Billing Monitor RPC usage and review billing information. | Tool | Description | Access | | --- | --- | --- | | get-rpc-usage | Get RPC usage with optional breakdown by endpoint, method, or chain | read-only | | get-billing | View billing invoices or payment history | read-only | ### Chains Query available chains and networks. | Tool | Description | Access | | --- | --- | --- | | list-chains | List all supported chains and their available networks | read-only | ## MCP Resources In addition to tools, the Quicknode MCP server exposes your endpoints as **MCP resources**. Resources let your AI assistant reference endpoint details directly in context without needing to call a tool first. In clients that support MCP resources, you can type `@quicknode` to browse and attach your endpoints to the conversation (e.g., `quicknode://endpoints/`). This is useful when you want the assistant to have your endpoint configuration readily available while working on a task, such as writing code that targets a specific chain or debugging a request. ## Example Prompts You do not need to reference tool names directly. The AI assistant maps natural language to the appropriate tool. Some examples: **Endpoint management:** - "Create a new Base mainnet endpoint" - "Show me all my endpoints and their current status" **Monitoring and debugging:** - "Check the logs for my Arbitrum endpoint from the last hour" - "Show me the performance metrics for my Ethereum endpoint over the past week" **Security:** - "Add JWT authentication to my Ethereum mainnet endpoint" - "Review security settings across all endpoints" **Usage and billing:** - "Show me my RPC usage broken down by chain for this month" - "Which endpoint is using the most credits this month?" **Rate limiting:** - "Set a rate limit of 100 requests per second on my Polygon endpoint" - "Add a method-specific rate limit for eth_call" tip - **Start simple** — Try asking "What endpoints do I have?" or "Show me my usage for this month" to get familiar with the available tools. - **Be specific** — When you have multiple endpoints, mention the chain or name to help the assistant find the right one quickly. ## How It Works The MCP server is hosted remotely at `https://mcp.quicknode.com/mcp` and uses OAuth 2.1 for authentication. When your AI assistant receives a request that involves Quicknode infrastructure, it calls the appropriate MCP tool, which makes authenticated requests to the Quicknode Admin API. The assistant handles the response formatting and presents the results in natural language. Write operations (creating endpoints, modifying security settings, deleting resources) require the **Admin** role and your explicit confirmation before the assistant executes them. If you connected with the **Viewer** role, the assistant can only perform read-only operations. tip Quicknode MCP manages your account-level infrastructure.
