MCP (Model Context Protocol) has really taken off as a way to amplify the power of AI, providing tools for utilising data to supplement what a foundation model has already been trained on, and so on.

With the rapid uptake of a standard and technology that has been development/implementation led aspects of governance and security can take time to catch up. While the use of credentials with tools and how they propagate is well covered, there are other attack vectors to consider. On the surface, it may seem superficial until you start looking more closely. A recent paper Model Context Protocol (MCP): Landscape, Security Threats, and Future Research Directions highlights this well, and I thought (even if for my own benefit) to explain some of the vectors.

I’ve also created a visual representation based on the paper of the vectors described.

The inner ring represents each threat, with its color denoting the likely origin of the threat. The outer ring groups threats into four categories, reflecting where in the lifecycle of an MCP solution the threat could originate.

I won’t go through all the vectors in detail, though I’ve summarized them below (the paper provides much more detail on each vector). But let’s take a look at one or two to highlight the unusual nature of some of the issues, where the threat in some respects is a hybrid of potential attack vectors we’ve seen elsewhere. It will be easy to view some of the vectors as fairly superficial until you start walking through the consequences of the attack, at which point things look a lot more insidious.

Several of the vectors can be characterised as forms of spoofing, such as namespace typosquatting, where a malicious tool is registered on a portal of MCP services, appearing to be a genuine service — for example, banking.com and bankin.com. Part of the problem here is that there are a number of MCP registries/markets, but the governance they have and use to mitigate abuse varies, and as this report points out, those with stronger governance tend to have smaller numbers of services registered. This isn’t a new problem; we have seen it before with other types of repositories (PyPI, npm, etc.). The difference here is that the attacker could install malicious logic, but also implement identity theft, where a spoofed service mimics the real service’s need for credentials. As the UI is likely to be primarily textual, it is far easier to deceive (compared to, say, a website, where the layout is adrift or we inspect URIs for graphics that might give clues to something being wrong). A similar vector is Tool Name Conflict, where the tool metadata provided makes it difficult for the LLM to distinguish the correct tool from a spoofed one, leading the LLM to trust the spoof rather than the user.

Another vector, which looks a little like search engine gaming (additional text is hidden in web pages to help websites improve their search rankings), is Preference Manipulation Attacks, where the tool description can include additional details to prompt the LLM to select one solution over another.

The last aspect of MCP attacks I wanted to touch upon is that, as an MCP tool can provide prompts or LLM workflows, it is possible for the tool to co-opt other utilities or tools to action the malicious operations. For example, an MCP-provided prompt or tool could ask the LLM to use an approved FTP tool to transfer a file, such as a secure token, to a legitimate service, such as Microsoft OneDrive, but rather than an approved account, it is using a different one for that task. While the MCP spec says that such external connectivity actions should have the tool request approval, if we see a request coming from something we trust, it is very typical for people to just say okay without looking too closely.

Even with these few illustrations, tooling interaction with an LLM comes with deceptive risks, partially because we are asking the LLM to work on our behalf, but we have not yet trained LLMs to reason about whether an action’s intent is in the user’s best interests. Furthermore, we need to educate users on the risks and telltale signs of malicious use.

Attack Vector Summary

The following list provides a brief summary of the attack vectors. The original paper examines each in greater depth, illustrating many of the vectors and describing possible mitigation strategies. While many technical things can be done. One of the most valuable things is to help potential users understand the risks, use that to guide which MCP solutions are used, and watch for signs that things aren’t as they should be.

AI to Agriculture

Now that details of the product I’ve been involved with for the last 18 months or so are starting to reach the public domain  (such as the recent announcement at the UN General Assembly on September 25), I can talk to a bit about what we’ve been doing.  Oracle’s Digital Government Global Industry Unit has been working on a solution that can help governments address the questions of food security.

So what is food security?  The World Food Programme describes it as:

Food security exists when people have access to enough safe and nutritious food for normal growth and development, and an active and healthy life. By contrast, food insecurity refers to when the aforementioned conditions don’t exist. Chronic food insecurity is when a person is unable to consume enough food over an extended period to maintain a normal, active and healthy life. Acute food insecurity is any type that threatens people’s lives or livelihoods.

World Food Programme

By referencing the World Food Programme, it would be easy to interpret this as a 3rd world problem. But in reality, it applies to just about every nation. We can see this, with the effect the war in Ukraine has had on crops like Wheat, as reported by organizations such as CGIAR, European Council, and World Development journal. But global commodities aren’t the only driver for every nation to consider food security. Other factors such as Food Miles (an issue that perhaps has been less attention over the last few years) and national farming economics (a subject that comes up if you want to it through a humour filter with Clarkson’s Farm to dry UK government reports and US Department of Agriculture.

Looking at it from another perspective, some countries will have a notable segment of their export revenue coming from the production of certain crops.  We know this from simple anecdotes like ‘for all the tea in China’, coffee variants are often referred to by their country of origin (Kenyan, Columbian etc.). For example, Palm Oil is the fourth-largest economic contributor in Malaysia (here). 

So, how is Oracle helping countries?

One of the key means of managing food security is understanding food production and measuring the factors that can impact it (both positively and negatively), which range from the obvious—like weather (and its relationship to soil, water management, etc.) —to what crop is being planted and when. All of which can then be overlayed with government policies for land management and farming subsidies (paying farmers to help them diversify crops, periodically allowing fields to go fallow, or subsidizing the cost of fertilizer).

Oracle is a technology company capable of delivering systems that can operate at scale. Technology and the recent progress in using AI to help solve problems are not new to agriculture; in fact, several trailblazing organizations in this space run on Oracle’s Cloud (OCI), such as Agriscout. Before people start assuming that this is another story of a large cloud provider eating their customers’ lunch, far from it, many of these companies operate at the farm or farm cooperative level, often collecting data through aerial imagery from drones and aircraft, along with ground-based sensors.  Some companies will also leverage satellite imagery for localized areas to complement these other sources. This is where Oracle starts to differentiate itself – by taking high-resolution imagery (think about the resolution level needed to differentiate Wheat and Maize, or spot rice and carrots, differentiate an orchard from a natural copse of trees). To get an idea, look at Google Earth and try to identify which crops are growing.

We take the satellite multi-spectral images from each ‘satellite over flight’ and break it down, working out what the land is being used for (ruling out roads, tracks, buildings, and other land usage).  To put the effort to do this into context, the UK is 24,437,600,000 square meters and is only 78th in the list of countries by area (here).  It’s this level of scale that makes it impractical to use more localized data sources (imagine how many people and the number of drones needed to fly over every possible field in a country, even at a monthly frequency).

This only solves the 1st step of the problem, which is to tell us the total crop growing area.  It doesn’t tell us whether the crop will actually grow well and produce a good yield.  For this, you’re going to need to know about weather (current, forecast, and historic trends), soil chemical composition and structure, and information such as elevation, angle, etc. Combined with an understanding of optimal crop growing needs (water levels, sun light duration, atmospheric moisture, soil types and health) – good crops can be ruined by it simply being too wet to harvest them, or store them dryly.  All these factors need to be taken into account for each ‘cell’ we’re detecting, so we can calculate with any degree of confidence what can be produced.

If this isn’t hard enough, we need to account for the fact that some crops may have several growing seasons per year, or succession planting is used, where Carrots may be grown between March and June, followed by Cucumbers through to August, and so on.

Using technology

Hopefully, you can see there are tens of millions of data points being processed every day, and Oracle’s data products can handle that. As a cloud vendor, we’re able to provide the computing scale and, importantly, elasticity, so we can crunch the numbers quickly enough that users benefit from the revised numbers and can work out mitigation actions to communicate to farmers. As mentioned, this could be planning where to best use fertilizer or publishing advice on when to plant which crops for optimal growing conditions. In the worst cases recognizing there is going to be a national shortage of a staple crop and start purchasing crops from elsewhere and ensure when the crops arrive in ports they get moved out to the markets  (like all large operations – as we saw with the Covid crises – if you need to react quickly, more mistakes can be made, costs grow massively driven by demand).

I mentioned AI, if you have more than the most superficial awareness of AI, you will probably be wondering how we use it, and the problems of AI hallucination – the last thing you want is a being asked to evaluate something and hallucinating (injecting data/facts that are not based on the data you have collected) to create a projection.  At worst, this would mean providing an indication that everything is going well, when things are about to really go wrong.  So, first, most of the AI discussed today is generative, and that is where we see issues like hallucinations.  We’re have and are adopting this aspect of AI where it fits best, such as explainability and informing visualization, but Oracle is making heavy use of the more traditional ideas of AI in the form of Machine Learning and Deep Learning which are best suited to heavy numerical computational uses, that is not to say there aren’t challenges to be ddressed with training the AI.

Conclusion

When it comes to Oracle’s expertise in the specialized domains of agriculture and government, Oracle has a strong record of working with governments and government agencies from its inception. But we’ve also worked closely with the Tony Blair Institute for Global Change, which works with many national government agencies, including the agriculture sector.

My role in this has been as an architect, focused primarily on applying integration techniques (enabling scaling and operational resilience, data ingestion, and how our architecture can work as we work with more and more data sources) and on applying AI (in the generative domain). We’re fortunate to be working alongside two other architects who cover other aspects of the product, such as infrastructure needs and the presentation tier. In addition, there is a specialist data science team with more PhDs and related awards than I can count.

Oracle’s Digital Government business is more than just this agriculture use case; we’ve identified other use cases that can benefit from the data and its volume being handled here. This is in addition to bringing versions of its better-known products, such as ERP, Healthcare (digital health records management, vaccine programmes, etc.), national Energy and Water (metering, infrastructure management, etc).

Fluent Bit and AI: Unlocking Machine Learning Potential

These days, everywhere you look, there are references to Generative AI, to the point that what have Fluent Bit and GenAI got to do with each other? GenAI has the potential to help with observability, but it also needs observation to measure its performance, whether it is being abused, etc. You may recall a few years back that Microsoft was trailing new AI features for Bing, and after only having it in use for a couple of days, it had been recorded generating abusive comments and so on (Microsoft’s Tay is such an example).

But this isn’t the aspect of GenAI (or the foundations of AI with Machine Learning (ML)) I was thinking about. Fluent Bit can be linked to GenAI through its TensorFlow plugin. Is this genuinely of value or just a bit of ‘me too’?

There are plenty of backend use cases once the telemetry has been incorporated into an analytics platform, for example:

  • Making it easy to query and mine the observability data, such as natural language searching – to simplify expressing what is being looked for.
  • Outlier / Anomaly detection – when signals, particularly metrics, diverge from the normal patterns of behavior, we have the first signs of a problem. This is more Machine Learning than generative AI.
  • Using AI agents to tune monitoring thresholds and alerting scenarios

But these are all backend, big data style use cases and do not center on Fluent Bit’s core value of getting data sources to appropriate destination systems for such analysis or visualization.

To incorporate AI into Fluent Bit pipelines, we need to overcome a key issue – AI tends to be computationally heavy – making it potentially too slow for streams of signals being generated by our applications and too expensive given that most logs reflecting ‘business as usual’ are, in effect, low value.

There are some genuine use cases where lightweight AI can deliver value. First, we should be a little more precise. The TensorFlow plugin is the TensorFlow Lite version, also known as LiteRT. The name comes from the fact that it is a lite-weight solution intended to be deployable using small devices (by AI standards). This fits the Fluent Bit model of having a small footprint.

So, where can we put such a use case:

  • Translating stack traces into actionable information can be challenging. A trained ML or AI model can help classify and characterize the cause of a stack trace. As a result, we can move from the log to triggering appropriate actions.
  • Targeted use cases where we’ve filtered out most signal data to help analyze specific events – for example, we want to prevent the propagation of PII data downstream. Some PII data can be easily isolated through patterns using REGEX. For example, credit card IDs are a pattern of 4 digits in 4 groups. Phone numbers and email addresses can also be easily identified. However, postal addresses aren’t easy, particularly when handling multinational addresses, where the postal code/zip code can’t be used as an indicative pattern. Using AI to help with such checks means we must filter out signals to only examine messages that could accidentally carry such information.

When adopting AI into such scenarios, we have to be aware of the problems that can impact the use of ML and AI. These use cases are less high profile than the issues of hallucinations but just as important. As we’re observing software, which will change over time. As a result, payloads or data shifts (technically referred to as data drift) and the detection rate can drop. So, we need to measure the efficacy of the model. However, issues such as data drift need to be taken into account, as the scenario being detected may change in volume, reflecting changes in software usage and/or changes in how the solution works.

There are ways to help address such considerations, such as tracking false positive outcomes, and if the model can provide confidence scoring, is there a trend in the score?

Conclusion

There are good use cases for using Machine Learning (and, to an extent, Artificial Intelligence) within an observability pipeline – but we have to be selective in its application as:

  • The cost of the computation can outweigh the benefits
  • The execution time for such computation can be notably slower than our pipeline, leading to risks of back pressure if applied to every event in the pipeline.
  • The effectiveness and how much data drift might occur (we might initially see very good results, but then things can fall off).

Possibly, the most useful application is when the AI/ML engine has been trained to recognize patterns of events that preceded a serious operational issue (strictly, this is the use of ML).

Forward-looking

The true potential for Gen AI is when we move beyond isolating potential faults based on pattern recognition to using AI to help recommend or even trigger remediation processes.
