AgentBreakWatch
Audit AI Agent SDKs and MCP servers for breaking changes, schema drift, and migration fixes.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (4)
🟢check_stack_drift(manifest)
Read-only audit of a package.json, requirements.txt, or .mcp.json configuration string against 256 live AI Agent SDKs and MCP servers. Flags breaking major version deltas, unpinned @latest MCP servers, and outdated dependencies with exact pin commands. Requires no authentication and returns a structured JSON report.
Input Schema
{
"type": "object",
"properties": {
"manifest": {
"type": "string",
"description": "Raw contents of .mcp.json, package.json, requirements.txt, or a newline-separated list of packages"
}
},
"required": [
"manifest"
],
"additionalProperties": false
}🟢get_package_stability(package)
Read-only lookup of live npm or PyPI version, publish timestamp, 90-day release velocity, stability score (0-100), MCP tools/list schema drift risk, and before/after migration code for a single AI Agent SDK or MCP server. Prefer this over check_stack_drift when inspecting one specific package by name or slug.
Input Schema
{
"type": "object",
"properties": {
"package": {
"type": "string",
"description": "Package name or slug (e.g. 'openai', '@modelcontextprotocol/sdk', '@playwright/mcp', 'fastmcp', 'mcp-clickhouse')"
}
},
"required": [
"package"
],
"additionalProperties": false
}🟢list_volatile_packages(kind, category, limit)
Read-only query that lists the fastest-changing or highest schema-drift-risk AI Agent SDKs and MCP servers from the live AgentBreakWatch telemetry index, sorted descending by 90-day release velocity. Supports filtering by kind ('sdk', 'mcp', 'all'), category hub slug, and result limit (1-50).
Input Schema
{
"type": "object",
"properties": {
"kind": {
"type": "string",
"enum": [
"all",
"sdk",
"mcp"
],
"description": "Filter by Agent SDK ('sdk'), MCP server ('mcp'), or 'all'"
},
"category": {
"type": "string",
"description": "Optional category hub slug (e.g. 'agent-sdks', 'aws-labs', 'database-backend', 'browser-automation', 'cloud-infra')"
},
"limit": {
"type": "number",
"description": "Maximum number of packages to return (default 15, max 50)"
}
},
"additionalProperties": false
}🟢get_archived_mcp_replacements
Read-only lookup returning the complete migration matrix for archived or frozen @modelcontextprotocol/server-* reference packages and their official 2026 vendor-maintained replacements. Takes no parameters and requires no authentication.
