Chainstack MCP

Overview

Chainstack runs a remote, Streamable HTTP MCP server requiring no local install. Public tools (no auth) cover documentation search for RPC methods and deployment guides, platform status/incident tracking, and live pricing lookups. Authenticated tools (API key) add project management and blockchain node deployment/configuration across multiple chains, plus testnet faucet requests. Works with Claude Code, Cursor, Codex, and other MCP clients.

• get_organization — Get organization name and ID.
• get_deployment_options — List blockchain/cloud/network combinations for node deployment. Call before create_node to get valid blockchain and cloud IDs.
• list_projects — List all projects. Projects are containers for nodes.
• create_project — Create a new project.
• list_nodes — List nodes with status and connection endpoints.
• get_node — Get a node's full details including endpoints and cloud info.
• create_node — Deploy a new blockchain node. Call get_deployment_options first for valid IDs. Trader nodes are region-bound (e.g., London, Ashburn, Singapore). Always confirm the region with the user before deployi
• get_project — Get project details.
• update_project — Update a project's name or description.
• delete_project — Delete a project (irreversible).
• update_node — Rename a node.
• delete_node — Delete a node (irreversible).
• list_node_access_rules — List 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 configured rules still return 403, that'
• create_node_access_rule — Add 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 the node; active origin rules limit whic
• update_node_access_rule — Change 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 user that the IP rules cover every IP that
• delete_node_access_rule — Delete 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 active rules left, the node accepts reque
• set_node_access_rules_status — Activate 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 the node, active origin rules limit which
• search_docs — Search Chainstack docs — blockchain RPC methods, node infrastructure, Web3 APIs, deployment guides, and code examples.
• get_doc_page — Get 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_status — Check platform status, active incidents, and maintenances.
• contact_chainstack — Submit a message to Chainstack's sales and support team. Use when the user wants to ask about pricing, get a custom quote, request a plan upgrade, request node customizations (Enterprise), report a p
• request_testnet_funds — Top up a testnet address from Chainstack's faucet. The faucet does not send a fixed amount — it tops the address up to the per-network maximum (e.g. 0.5 ETH for sepolia). If the address already sits
• get_chainstack_pricing — Fetch Chainstack's public pricing and return a normalized snapshot. Use this to answer pricing questions before quoting the user: plan fit, overage math, per-chain dedicated-node costs, and add-on pr

Answers a call

the server answered get_organization with an error (Error calling tool 'get_organization': No API key provided. Fetch https://mcp.chainstack.com/ (GET) for connection config with API key setup. The user needs a C)

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
