1.8.0-experimental.2 (2026-02-23)

Features

Allow server "description" to be configured

Example:

server_info:
  name: "Acme Corp GraphQL Server"
  version: "2.0.0"
  title: "Acme MCP Server"
  website_url: "https://acme.com/mcp-docs"
  description: "MCP server for Acme Corp's GraphQL API"

Support custom tool descriptions for manifest operations

Users can now provide custom tool descriptions for operations loaded from persisted query manifests by adding a descriptions map to the operations config. This lets AI models better understand when and how to use each tool, without requiring changes to the standard manifest format.

operations:
  source: manifest
  path: ./manifest.json
  descriptions:
    GetAlerts: "Get active weather alerts for a US state"
    GetForecast: "Get a detailed weather forecast for a coordinate"

Fixes

Fix server crash on collection sync with invalid operations

A single operation with malformed variables JSON in a collection would crash the entire server. Invalid operations are now skipped with a warning, and the server continues serving with the remaining valid operations.
