Chainstack updates: October 23, 2026

Every Chainstack MCP server tool now has a readable title and states how it behaves, and VS Code no longer asks you to review results from tools that return Chainstack’s own docs, status and pricing.

MCP Server. The Chainstack MCP server has been optimized with the following updates:

• Every tool has a readable title, such as Create node or Search Chainstack docs. Clients that display titles, such as VS Code, show it in place of the raw tool name.
• Every tool declares all four MCP annotation hints, which your AI client uses to decide when to ask you before a call. The hints say:
  • Whether the tool only reads data
  • Whether it can change or delete something
  • Whether repeating a call is safe
  • Whether its results can contain text from outside Chainstack
• Tools that return Chainstack’s own content no longer trigger a result review in VS Code before your agent sees the output:
  • Docs
  • Platform status
  • Pricing
  • Deployment options
• Tools that return your project, node or organization data, and every tool that changes something, keep their review and approval prompts.
