ZERO-SIGNUP CONFIG AUDITOR

Paste Your Agent Stack to Detect Breaking Releases & Drift

Compare your `.mcp.json`, `package.json`, or `requirements.txt` against our live index of 30 Agent SDKs and 226 MCP servers. We flag major version jumps, archived official MCP servers, and unpinned `@latest` servers that can silently break tool calls.

BREAKING DELTA@modelcontextprotocol/server-filesystem

Your spec: 1.0.2 -> Live: v2.0.0

Major or breaking version delta (1.0.2 -> 2.0.0). Major v2.0.0 release enforces roots protocol capabilities, tightens symlink path traversal validation, and updates edit_file dryRun diff schema.

npx -y @modelcontextprotocol/server-filesystem@2.0.0

CURRENT@modelcontextprotocol/server-github

Your spec: 2025.4.8 -> Live: v2025.4.8

Matches live NPM version v2025.4.8 (published 2025-04-08).

npx -y @modelcontextprotocol/server-github@2025.4.8

BREAKING DELTA@supabase/mcp-server-supabase

Your spec: 0.9.0 -> Live: v0.14.0

Major or breaking version delta (0.9.0 -> 0.14.0). v0.14.x supports --read-only and --project-ref scoping; execute_sql and apply_migration split DDL vs DML operations.

npx -y @supabase/mcp-server-supabase@0.14.0

View Diff ->

UNPINNED @LATEST@playwright/mcp

Your spec: latest -> Live: v0.0.83

Unpinned (@latest) dependency with HIGH schema drift risk. Silent tool schema or export shifts will hit production immediately. Pin to v0.0.83.

npx -y @playwright/mcp@0.0.83

View Diff ->

BREAKING DELTAfirecrawl-mcp

Your spec: 2.1.0 -> Live: v3.34.1

Major or breaking version delta (2.1.0 -> 3.34.1). v3.x upgrades to Firecrawl v2 API: firecrawl_extract requires schema or prompt, and firecrawl_scrape removes deprecated pageOptions.

npx -y firecrawl-mcp@3.34.1

1. Pin Unpinned MCP Servers

Running `npx -y @org/mcp-server@latest` in production pulls new `tools/list` input schemas on every container restart. Always pin exact versions.

2. Replace Archived Reference Servers

Several early `@modelcontextprotocol/server-*` packages (`server-github`, `server-postgres`, `server-puppeteer`) are archived and superseded by vendor-maintained servers.

3. Automate Schema Drift Alerts

Save your stack once to get instant email or Slack/webhook alerts with tested before-and-after code snippets whenever a dependency ships a breaking change.
