chainstack

A connection to Chainstack, a service for running and managing blockchain network nodes and projects.

In plain words
What is it for?
Use it to deploy, update, migrate, inspect, or remove blockchain nodes and projects, check service status, search Chainstack documentation, or request testnet funds.
Why use it?
It lets an agent work with node infrastructure and Chainstack information without handling each platform task manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chainstack scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Chainstack MCP Server

Endpoint: https://mcp.chainstack.com/mcp

Access tiers

The server has two tiers of access from the same endpoint.

No API key required (just connect to the URL, no auth header needed):

  • search_docs — search Chainstack documentation
  • get_doc_page — get full content of a documentation page
  • get_platform_status — check platform status, incidents, maintenances
  • contact_chainstack — submit a message to Chainstack's team (sales, support, general)
  • get_chainstack_pricing — live pricing snapshot (plan tiers, feature matrix, add-ons, dedicated-node catalog)

API key required (pass Bearer <chainstack-api-key>):

  • All platform tools: 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
  • request_testnet_funds — top up a testnet address from Chainstack's faucet

Node tiers

Chainstack has two node tiers. Picking the right one is critical when deploying.

Global Nodes (cloud CC-0016, provider chainstack_global):

  • Load-balanced across regions, routes to nearest location
  • Deploys instantly
  • Available on all plans including free
  • Best for: getting started, general RPC access

Trader Nodes (clouds CC-0020 through CC-0028, provider chainstack_managed):

  • Region-bound, dedicated resources
  • Deploys in 3-6 minutes
  • Paid plans only
  • Full and archive modes available
  • Best for: low-latency trading, MEV, heavy indexing

The node_tier field in tool responses shows "Global" or "Trader" for clarity.

Workflows

Deploy a node

This is a multi-step flow. Always follow this order:

  1. Get deployment options: Call get_deployment_options to see available blockchain/cloud/network combinations. Note the blockchain and cloud IDs you need.
  2. Confirm location with the user: Trader nodes are region-bound (e.g., London, Ashburn, Singapore). Always show the user the available regions and ask which one before deploying. Region affects latency and cannot be changed after deployment.
  3. Get or create a project: Call list_projects to find an existing project, or create_project to make a new one. Note the project id (format: PR-123-456-789).
  4. Create the node: Call create_node with name, project, blockchain, and cloud from the previous steps.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

chainstack is a skill published in the GitHub repository chainstacklabs/mcp-server (4 stars, last pushed 19d ago), licensed MIT. It adds 66 tokens to every session and 3,697 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
