### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

**Important note about the retirement of the OWASP Meetup platform** Fellow OWASP Toronto members, We are making an important announcement regarding an upcoming transition. The OWASP Foundation has announced that they will be retiring their Meetup Pro subscription effective January 31, 2026: https://owasp.org/blog/2026/01/13/retiring-meetup.html This means that our OWASP Toronto Meetup group may be removed in the coming days. We understand this may be short notice, so we want to make this announcement before we lose access. You are an important part of our chapter community. Many attendees I have spoken to have discovered OWASP Toronto via Meetup. To continue engaging with the community while using a platform that enables discoverability, we will moving to the [Evenbrite](https://owasp-toronto-chapter.eventbrite.com/) for publishing our events. You can continue to follow us via our [Google Group mailing list](https://groups.google.com/a/owasp.org/g/toronto-chapter), our [Chapter page](https://owasp.org/www-chapter-toronto/), our [LinkedIn group](https://www.linkedin.com/showcase/owasp-toronto-chapter/), our [YouTube channel](https://www.youtube.com/channel/UCqmBl-u_4cOEiH3OXWE3sPg), our Slack channel ([#owasp-toronto-chapter](https://owasp.slack.com/archives/C075DRCB1PZ), does not require an OWASP membership), as well as on our new [Discord channel](https://discord.gg/eg3upJ6N).

A healthy body of knowledge has been devoted to exploring how to better increase awareness, in any given topic, among members of the general public which have explored the role of word of mouth (WOM) and electronic word of mouth (eWOM) in spreading awareness. In recent years, the rise of social media platforms as an alternative communication channel has created efforts to promote cybersecurity awareness online regarding the numerous cybersecurity threats. However, little research attention has been devoted to exploring eWOM communication on social media surrounding cybersecurity awareness. Moreover, no research to date has considered the impact of the COVID-19 pandemic on these eWOM discussions related to cybersecurity awareness. To address these literature gaps, this research collected 227, 270 relevant tweets surrounding cybersecurity awareness from 2018 to 2022 conducting an exploratory analysis of the corpus using social network analyses, topic modelling and semantic similarity analysis. The results found topics rose in prominence and then dissipated as newer topics emerged while information was found to spread incredibly far despite a high degree of community forming, suggesting the online discourse is very open and evolving over time. These findings illustrate the potential of social media as an effective tool for raising cybersecurity awareness. The impact of COVID-19 observed an increase in the reach of information in addition to new specific topics emerging in the discourse, but the effects appear to be temporary. Speaker: Dane Vanderkooi Dane Vanderkooi is a fifth-year Doctoral Candidate in management science at TorontoMet University who specializes in researching cybersecurity and digital privacy behaviours. He completed his bachelor's of commerce at Uottawa and holds a master's in management science degree from Ryerson University.

From “simple” chatbot integrations to LLMs wired directly into business logic — and agents running entire application flows — organizations are accumulating Shadow AI: untracked, ungoverned, and often dangerously over-privileged. This talk shows how AI quietly changes application behavior at runtime: expanding trust boundaries, introducing non-deterministic authorization paths, and creating blast radiuses that static inventories and policy checklists cannot capture. Using real-world architectural patterns and runtime signals, we’ll demonstrate how security teams can identify where AI is actually used, what it can access, and how attackers abuse AI-driven logic to exploit new classes of vulnerabilities. Attendees will leave with a practical framework for securing AI-powered applications — grounded in runtime behavior and evidence, not assumptions. Speaker: Daniel Shechter Daniel Shechter is the CEO and Co-Founder of Miggo, an Application Detection and Response platform. Shechter has an impressive background in both threat intelligence and within the security industry. Before founding Miggo he was leading cyber security teams in Israel's elite cyber intelligence division, Unit 8200.

Shechter is an industry expert in security, incident detection and response, threat intelligence, and attack observability.

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.
