Chainstack MCP: deploy and manage blockchain nodes from an AI app

Connect Chainstack to Claude, ChatGPT or Cursor

1. 1Click Connect Chainstack free. There's no sign-in, so its tools are ready at once.
2. 2`delete_node`, `delete_project` and `delete_node_access_rule` can't be undone, and `set_node_access_rules_status` changes who can reach a node within seconds. Switch those off unless you want your AI app making that call.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Ask your AI app to list your Chainstack nodes and their status, then open Activity to see the `list_nodes` call.

Node work you can do from Claude or Cursor

• Check valid blockchain, cloud and network combinations with `get_deployment_options`, then deploy a node with `create_node`.
• List nodes with their status and connection endpoints using `list_nodes`.
• Add IP or origin allowlist rules to a Global node with `create_node_access_rule`.
• Search Chainstack docs for RPC methods and code examples with `search_docs`, or check incidents with `get_platform_status`.
• Request testnet funds from Chainstack's faucet.

Keep irreversible Chainstack calls in check

• Switch off the three delete tools; they're hidden from your AI app and refused if called.
• Use a policy to warn or block before an access-rule change limits which clients can reach a node.
• Activity records each call, so a new node or a changed allowlist can be traced to the request behind it.

What you get with Chainstack and ContextGate

• Your AI apps can use ChainstackClaude, Cursor, ChatGPT and other AI apps reach Chainstack through the one ContextGate connection you add to them.
• You choose which tools they can useSwitch off any Chainstack tool you don't want used. It's hidden from your AI apps and refused if called.
• Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.

Chainstack tools

Examples of what your AI apps can do in Chainstack. You'll see the exact list of tools after you connect it.

• get_organizationGet organization name and ID.
• get_deployment_optionsList blockchain/cloud/network combinations for node deployment. Call before create_node to get valid blockchain and cloud IDs.
• list_projectsList all projects. Projects are containers for nodes.
• create_projectCreate a new project.
• list_nodesList nodes with status and connection endpoints.
• get_nodeGet a node's full details including endpoints and cloud info.
• create_nodeDeploy a new blockchain node. Call get_deployment_options first for valid IDs. Use a Global option (node_tier "Global") from get_deployment_options.
• get_projectGet project details.
• update_projectUpdate a project's name or description.
• delete_projectDelete a project (irreversible).
• update_nodeRename a node.
• delete_nodeDelete a node (irreversible).
• list_node_access_rulesList a node's access rules (IP and Origin allowlists, Global nodes only). With no active rules, the node accepts requests from any IP and origin. If correctly
• create_node_access_ruleAdd an IP or Origin allowlist rule to a Global node. New rules are deactivated and do nothing until activated. Active IP rules limit which client IPs can call
• update_node_access_ruleChange an access rule's value, or activate or deactivate it. A rule's type can't change; delete it and create a new one. Before activating, confirm with the us
• delete_node_access_ruleDelete an access rule from a node (irreversible). Deleting an active rule changes who can reach the node; the result says what's enforced afterwards. With no a
• set_node_access_rules_statusActivate or deactivate every access rule on a node at once. Activating enforces every rule within about 10 seconds: active IP rules limit which IPs can call th
• search_docsSearch Chainstack docs — blockchain RPC methods, node infrastructure, Web3 APIs, deployment guides, and code examples.
• get_doc_pageGet the full content of a Chainstack documentation page. Use after search_docs to fetch the complete page when a snippet isn't enough.
• get_platform_statusCheck platform status, active incidents, and maintenances.
