Documentação

Havoptic API Documentation

All Havoptic data is publicly accessible without authentication. Use these endpoints to programmatically access release data, feature comparisons, and feeds for AI coding tools.

Developer docs with a quickstart, API keys and rate limits, pagination, typed changes, webhooks, MCP setup and the error catalog: https://www.havoptic.com/docs.

Why Havoptic's API

Built for depth on AI coding tools rather than breadth across every changelog.

  • Typed change items with evidence - Each release is split into typed changes (feature, fix, breaking, deprecation, security, and more), and every item carries a verbatim quote from the source notes plus a confidence score. Typed changes cover releases from 2026-10-19 onward; older releases report changes_available: false.
  • Cross-tool feature intelligence - Who shipped a feature first, how long others took to follow, and the mechanics underneath, compared across every tracked AI coding tool.
  • Upgrade reports - Breaking changes, deprecations, and migration notes rolled up for any version range via /api/v1/tools/{id}/upgrade or the get_upgrade_notes MCP tool.
  • Agent-first ergonomics - MCP tools with token budgets, markdown output, citation links, and freshness metadata, plus OpenAPI 3.1 and JSON Schemas for typed clients.
  • Provenance - Raw release notes are retained and hashed, and every AI-derived field is labeled with the model and prompt version that produced it.

MCP Server

Havoptic is queryable directly from AI assistants via the Model Context Protocol. Remote MCP server: https://mcp.havoptic.com/mcp (streamable HTTP transport, read-only, no authentication). Connect from Claude Code: claude mcp add --transport http havoptic https://mcp.havoptic.com/mcp

MCP tools: list_tools, get_latest_releases, whats_changed_since, search_changes, get_release, get_upgrade_notes, get_breaking_changes, compare_tools, feature_adoption, cadence_stats; deprecated aliases (kept until at least 2027-11-01): list_tracked_tools → list_tools, latest_releases → get_latest_releases, release_history → get_latest_releases with since, search_release_notes → search_changes, feature_timeline → feature_adoption.

Official MCP Registry name: com.havoptic/releases (https://registry.modelcontextprotocol.io/v0/servers?search=com.havoptic/releases). Server card: https://www.havoptic.com/.well-known/mcp.json.

MCP resources: havoptic://tools, havoptic://tools/{id}, havoptic://releases/{id}, havoptic://tools/{id}/changelog?since=, havoptic://schema/{name}, havoptic://docs/api. MCP prompts: weekly_ai_tools_brief, upgrade_check, compare_for_team, release_announcement.
