contact_chainstackContact Chainstackcan change or delete data
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 problem, or reach Chainstack for any reason. Posts to the same contact form as chainstack.com/contact/. ## Before calling this tool CRITICAL — follow these steps EVERY time: 1. Draft the message based on your conversation context. 2. Show the user the EXACT message, email, and name you will send. 3. If the user has a Chainstack API key configured, tell them their org name and ID will be inclu…
create_nodeCreate 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 deploying — region cannot be changed after deployment.
create_node_access_ruleCreate node access rulecan change or delete data
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 which Origin headers it accepts. With both kinds active, a request must pass both. Everything else gets HTTP 403 within about 10 seconds. Rules don't affect the Chainstack API, so they can always be changed or deactivated with these tools. Before activating, confirm with the user that the IP rules cover every IP that calls the node (servers, CI, their own machine); you can't check this. Origin rules …
create_projectCreate project
Create a new project.
delete_nodeDelete nodecan change or delete data
Delete a node (irreversible).
delete_node_access_ruleDelete node access rulecan change or delete data
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 requests from any IP and origin.
delete_projectDelete projectcan change or delete data
Delete a project (irreversible).
get_chainstack_pricingGet Chainstack pricingread-only
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 pricing (Unlimited Node flat-fee tiers, Yellowstone gRPC streams, Warp transactions, dedicated-node base rates). This tool returns the menu, not the bill — the calling agent does the arithmetic. All prices are list prices in USD; disclaimers are surfaced in the `disclaimers` field. Per-method RU billing rules are NOT in these sources. Plan-level rates (Full Node = 1 RU, Archive Node = 2 RU) are in…
get_deployment_optionsGet deployment optionsread-only
List blockchain/cloud/network combinations for node deployment. Call before create_node to get valid blockchain and cloud IDs.
get_doc_pageGet docs pageread-only
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_nodeGet noderead-only
Get a node's full details including endpoints and cloud info.
get_organizationGet organizationread-only
Get organization name and ID.
get_platform_statusGet platform statusread-only
Check platform status, active incidents, and maintenances.
get_projectGet projectread-only
Get project details.
list_node_access_rulesList node access rulesread-only
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's a support case: offer contact_chainstack.

list_nodesList nodesread-only
List nodes with status and connection endpoints.
list_projectsList projectsread-only
List all projects. Projects are containers for nodes.
request_testnet_fundsRequest testnet fundscan change or delete data
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 above the cap, the call fails with an insufficient-balance error. Describe the behavior to the user as "top up" not "give", and surface the returned `amountSent` so they see the actual delta. One top-up per network every 24 hours: a repeat call for the same network is refused (429) if the same organization or the same address got funds there in the last 24 hours, and the error says when the next …
search_docsSearch Chainstack docsread-only
Search Chainstack docs — blockchain RPC methods, node infrastructure, Web3 APIs, deployment guides, and code examples.
set_node_access_rules_statusActivate or deactivate all node access rulescan change or delete data
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 Origin headers it accepts, and a request must pass both kinds. Others get HTTP 403. First confirm with the user that the IP rules cover every IP that calls the node (servers, CI, their own machine); you can't check this. Origin rules block every request without an Origin header (servers, scripts, curl), even from an allowed IP. Deactivating opens the node to any IP and origin.
update_nodeRename nodecan change or delete data
Rename a node.
update_node_access_ruleUpdate node access rulecan change or delete data
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 calls the node. Activating the first origin rule blocks every request without an Origin header (servers, scripts, curl), even from allowed IPs. Changing or deactivating a rule can block clients that only it allowed.
update_projectUpdate projectcan change or delete data
Update a project's name or description.
