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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.04379 |
| Opus 5.5 | $0.00030 | $0.01752 |
| Sonnet 5.5 | $0.00015 | $0.00876 |
| Haiku 4.5 | $0.00008 | $0.00438 |
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 7d 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.
description: Work with the Chainstack MCP server to manage blockchain nodes and projects. Use when deploying nodes, restricting node access with IP or origin allowlists, migrating to Chainstack from another RPC provider How it starts
The opening of the file, as written. The whole thing — 316 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 documentationget_doc_page— get full content of a documentation pageget_platform_status— check platform status, incidents, maintenancescontact_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 - Node access rules:
list_node_access_rules,create_node_access_rule,update_node_access_rule,delete_node_access_rule,set_node_access_rules_status 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 (provider chainstack_managed; cloud IDs vary by region, so take them from get_deployment_options):
- 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:
- Get deployment options: Call
get_deployment_optionsto see available blockchain/cloud/network combinations. Note theblockchainandcloudIDs you need. - 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.
- Get or create a project: Call
list_projectsto find an existing project, orcreate_projectto make a new one. Note the projectid(format:PR-123-456-789). - Create the node: Call
create_nodewithname,project,blockchain, andcloudfrom 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 8d ago), licensed MIT. It adds 76 tokens to every session and 4,379 once invoked, about $0.0003 per session on Opus 5.5. 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.
