CVE-2026-59950high · fixed

MCP Python SDK: WebSocket server transport does not support Host/Origin validation

### Summary In affected versions, the deprecated WebSocket server transport (`mcp.server.websocket.websocket_server`) accepted the WebSocket handshake without applying any `Host` or `Origin` header validation. The `TransportSecuritySettings` mechanism that the SSE and Streamable HTTP transports use for this purpose was not wired into the WebSocket transport, so there was no SDK-level way to restrict which origins could connect. ### Am I affected? Only if a developer's application server exposes

MCP Python SDK: HTTP transports serve session requests without verifying the authenticated principal

### Summary In affected versions, the SSE and Streamable HTTP server transports routed incoming requests to an existing session based only on the session identifier, without verifying that the request was authenticated as the same principal that created the session. Anyone who learned or guessed a session ID could send JSON-RPC messages on that session, regardless of which bearer token the request carried. ### Am I affected? Only if a developer's application server uses an HTTP transport (SSE,

MCP Python SDK: Experimental task handlers allow any client to access and cancel other clients' tasks

### Summary In affected versions, the default request handlers installed by the experimental tasks feature (`server.experimental.enable_tasks()`) did not check which session created a task before acting on it. On a server with more than one connected client, any client could observe, read results from, and cancel tasks belonging to other clients. ### Am I affected? Only if the developer's application server calls `server.experimental.enable_tasks()`. If `grep -r enable_tasks` over their codebas

Model Context Protocol (MCP) Python SDK does not enable DNS rebinding protection by default

### Description The Model Context Protocol (MCP) Python SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication using `FastMCP` with streamable HTTP or SSE transport, and has not configured `TransportSecuritySettings`, a malicious website could exploit DNS rebinding to bypass same-origin policy restrictions and send requests to the local MCP server. This could allow an attacker to invoke tools or ac

CVE-2025-53366high · fixed

MCP Python SDK vulnerability in the FastMCP Server causes validation error, leading to DoS

A validation error in the MCP SDK can cause an unhandled exception when processing malformed requests, resulting in service unavailability (500 errors) until manually restarted. Impact may vary depending on the deployment conditions, and presence of infrastructure-level resilience measures. Thank you to Rich Harang for reporting this issue.

README

qb-auto — QuickBooks MCP Server

MCP (Model Context Protocol) server that gives Claude Code native tools for QuickBooks Online automation.

Replaces 50K-token browser_snapshot round-trips with targeted DOM extraction (~200-500 tokens) and compound Playwright actions that complete entire workflows in one tool call.

Tools

Tool	Description
`qb_page_state`	Check current page/dialog state (~50 tokens)
`qb_list_invoices`	List all visible invoices with optional customer filter
`qb_invoice_state`	Inspect an open invoice form (line items, totals)
`qb_receive_payment`	Record a payment (navigate → fill → save → confirm)
`qb_create_invoice`	Create a new invoice with line items
`qb_delete_line_item`	Delete a line from an existing invoice
`qb_edit_payment_amount`	Edit an existing payment amount
`qb_batch_receive_payments`	Record multiple payments in sequence
`qb_report`	Run any QBO report (30+ report types) with date range options
`qb_report_pnl`	Profit & Loss (income statement)
`qb_report_balance_sheet`	Balance Sheet (assets, liabilities, equity)
`qb_report_ar_aging`	A/R Aging Summary (who owes, how overdue)
`qb_report_customer_balance`	Customer Balance Summary
`qb_report_open_invoices`	Open (unpaid) Invoices
`qb_report_vendor_balance`	Vendor Balance Summary

Token Savings

Workflow	Before (snapshots)	After (MCP)	Savings
Receive Payment	~290K tokens	~13K tokens	95%
Create Invoice	~350K tokens	~18K tokens	95%
Full session (5 ops)	~500K tokens	~45K tokens	91%

Setup

Prerequisites

Python 3.10+
mcp and playwright packages
Chrome running with remote debugging: google-chrome --remote-debugging-port=9222

Install

pip install mcp playwright
playwright install chromium

Register with Claude Code

Add to ~/.mcp.json:

{
  "mcpServers": {
    "quickbooks": {
      "type": "stdio",
      "command": "python3",
      "args": ["/path/to/qb-auto/server.py"]
    }
  }
}

Configuration

The server connects to Chrome via CDP (Chrome DevTools Protocol) on port 9222 by default. Set the CDP_PORT variable in server.py if using a different port.

Architecture

Extractors: JavaScript functions injected via page.evaluate() that return compact JSON from QB's DOM using ARIA selectors
Actions: Complete Playwright workflows using getByRole() and getByLabel() — ARIA-stable selectors that survive QB page reloads
Playbook: PLAYBOOK.md contains the full reference for manual use with browser_evaluate/browser_run_code

Files

File	Purpose
`server.py`	MCP server with 15 tools
`extractors.js`	Standalone JS extractor functions (reference)
`actions.js`	Playwright action templates (reference)
`PLAYBOOK.md`	Quick reference for manual browser automation

How It Works

Claude calls qb_receive_payment(invoice_num="6865", amount="22500", method="ACH")
Server connects to your Chrome browser via CDP
Navigates to QB invoices, finds the invoice, opens payment dialog
Fills method, amount, saves, handles confirmations
Returns compact JSON result (~200 tokens)

No browser snapshots. No 50K token pages. One tool call = one complete operation.
