A Comprehensive Survey of AI Agent Frameworks and Their Applications in Financial Services

1. Introduction

The emergence of agentic AI—AI systems capable of autonomous, multi-step reasoning and action—marks a new era in artificial intelligence [1,2,3]. Large Language Models (LLMs) have enabled agents to reason, plan, and interact with complex environments, making them suitable for a wide range of enterprise and industrial applications [4]. In the financial sector, agentic AI is being explored for tasks ranging from trading and investment analysis to compliance and workflow automation [5,6,7].

The financial services industry is undergoing a radical transformation through the adoption of AI agent frameworks [8]. As noted by [4], generative AI is becoming a utility similar to electricity, with multi-agent systems emerging as the next evolutionary step. Recent developments in 2024-2025 show remarkable progress in both agent frameworks and their financial applications [9,10,11].

However, several important considerations need to be addressed in future work:

• Scalability: Evaluating the scalability of the architecture to handle a large number of agents and complex financial scenarios.
• Real-time Performance: Assessing the system’s ability to operate in real-time and make timely decisions in dynamic market conditions.
• Regulatory Compliance: Ensuring that the system complies with relevant financial regulations and ethical guidelines.
• Integration with Existing Systems: Exploring how the architecture can be integrated with existing financial systems and infrastructure.

1.1. Related Work

The intersection of multi-agent systems and artificial intelligence has a long history, with early research focusing on distributed problem-solving, cooperative robotics, and game theory. Chen [12] laid the groundwork for applying computationally intelligent agents in economics and finance, demonstrating their ability to model complex market behaviors and agent interactions.

The advent of Large Language Models (LLMs) has revolutionized the field of AI, enabling the development of more sophisticated and autonomous agents. Agentic AI, as highlighted by Pounds [1] and Jadhav [2], represents a paradigm shift towards AI systems that can reason, plan, and act autonomously, significantly expanding the potential of MAS. Winston [3] emphasizes the importance of understanding AI agents and their growing impact.

Several platforms and frameworks have emerged to facilitate the development of AI agents. LangChain [13] provides a versatile toolkit for building agents that can interact with external data sources and tools. LangGraph [14] offers a lower-level abstraction for building stateful and interactive agentic applications. CrewAI [15] focuses on orchestrating collaborative multi-agent workflows. AutoGen [16] simplifies the creation of multi-agent conversations. Other notable frameworks include Semantic Kernel [17], Agentforce [18], Mosaic AI Agent Framework [19,20], and platforms offered by major cloud providers such as Google Cloud’s Vertex AI Agent Builder [21], Amazon Bedrock Agents [22], Azure Cosmos DB [23], and IBM watsonx.ai [24]. Pydantic-AI [25,26] provides tools for integrating Pydantic with LLMs in agent development.

Comparative analyses of these frameworks, such as those by Aydın [27], Relari AI [10], and others [9,11,28,29,30,31], offer valuable insights into their strengths, weaknesses, and suitability for different applications.

The application of AI agents in the financial domain is a rapidly evolving area. Reports from McKinsey [8] and the World Economic Forum [32] highlight the transformative potential of agentic AI in revolutionizing financial services.

8. Theoretical Foundations of Agentic AI

Based on the surveyed literature, we identify ten core theoretical concepts that underpin modern agentic AI systems:

• Agentic Design Patterns - Architectural templates for creating autonomous agents capable of iterative planning and tool use [1]. Characterized by:

  $$A=(S,\Pi ,M,T)$$

  (1)

  where S=states, $\Pi$=policies, M=memory, T=tools.
• Multi-Agent Scaling Laws - Quantitative relationships between agent count and system performance [53]. Demonstrated through:

  $$\mathcal{P}\left(n\right)\sim n^{\alpha }log\left(n\right)$$

  (2)

  where $\alpha$ is task-dependent.
• Verbal Reinforcement Learning - Conceptual reinforcement through language feedback rather than numeric rewards [7]. Formalized as:

  $${\pi }_{t+1}={\pi }_t+\eta \nabla \mathbb{E}\left[f_{\mathrm{lang}}\left(R\right)\right]$$

  (3)
• Financial Market Microfoundations - Agent-based models explaining macro phenomena through individual agent behaviors [33]. Price formation follows:

  $$p_{t+1}=p_t+\sum _i{w}_i{a}_i(p_t,x_i)$$

  (4)
• Multimodal Fusion Theory - Framework for combining diverse financial data modalities [5]. Uses attention mechanisms:

  $$h=\mathrm{softmax}(Q{K}^T/\sqrt{d})V$$

  (5)
• Agentic Workflow Optimization - Mathematical formulation of task decomposition in financial processes [6]. Minimizes:

  $$\mathcal{L}=\sum _{k=1}^K{\parallel T_k-\bigcup _i{\pi }_i^k\parallel }^2$$

  (6)
• Conceptual Alignment - Ensuring agent reasoning aligns with financial domain concepts [7]. Measured by:

  $$\mathcal{A}=\mathbb{E}\left[\mathrm{sim}(c_{\mathrm{human}},c_{\mathrm{agent}})\right]$$

  (7)
• Risk-Aware Learning - Adaptation mechanisms considering financial risk constraints [40]. Policies satisfy:

  $$\pi \in \left\{{\pi }^{\prime }\right|\mathbb{P}(r_{\mathrm{risk}}>\theta )<ϵ\}$$

  (8)
• Computational Principal-Agent Theory - Formalizing delegation in AI-human teams [12]. Models:

  $$\underset{a\in A}{max}{u}_p\left(a\right)\mathrm{s}.\mathrm{t}.a\in arg\underset{a^{\prime }}{max}{u}_a\left(a^{\prime }\right)$$

  (9)
• Generative Economic Equilibrium - Stable states in AI-augmented financial systems [33]. Requires:

  $$\forall i,{\pi }_i^{*}\in \mathrm{BR}\left({\pi }_{-i}^{*}\right)$$

  (10)

  where BR denotes best response.

These theoretical constructs provide the mathematical foundation for current agentic AI systems in finance, spanning individual agent design to market-scale interactions. The field continues to evolve through formalization of these concepts [44,61].

10. Proposed Architectures: Mathematical and Algorithmic Foundations

Recent literature introduces a variety of architectures for agentic AI, each with unique mathematical and algorithmic principles.

10.1. Agent-Native and Modular Architectures

Agent-native foundation models are designed for multi-step planning, dynamic tool use, and memory integration [1,2,3]. These models enable agents to adaptively allocate computational resources, which can be expressed as:

$$y=f(x;\theta ,\mathcal{A})$$

where x is the input, $\theta$ are model parameters, and $\mathcal{A}$ represents agentic actions or tools invoked during reasoning [1].

10.2. Meta-Agent and Hierarchical Planning

Meta-agent architectures introduce a supervisory agent that coordinates specialized sub-agents, optimizing for global objectives. This can be formalized as a hierarchical optimization problem:

$$\underset{\left\{{\pi }_i\right\}}{min}\sum _{i=1}^N{C}_i\left({\pi }_i\right)\mathrm{s}.\mathrm{t}.\bigcup _{i=1}^N{\pi }_i\in \mathcal{G}$$

where ${\pi }_i$ is the plan for agent i, $C_i$ is its cost, and $\mathcal{G}$ is the set of global goals.

10.3. Learning Agents and Reinforcement Learning

Learning agents adapt their behavior through feedback, often using reinforcement learning (RL) or RL from human feedback. The RL objective is:

$${\pi }^{*}=arg\underset{\pi }{max}\mathbb{E}\left[\sum _{t=0}^T{\gamma }^t{r}_t\mid \pi \right]$$

where $\pi$ is the policy, $r_t$ the reward at time t, and $\gamma$ the discount factor.

10.4. Automated Agent Design

Automated agent design leverages evolutionary algorithms to search the space of agent architectures. The process is:

$${\theta }^{*}=arg\underset{\theta }{max}\mathcal{F}\left(\theta \right)$$

where $\theta$ encodes an agent architecture and $\mathcal{F}$ is a fitness function measuring performance.

10.5. Multi-Agent Coordination

Multi-agent systems distribute tasks and coordinate via protocols such as negotiation or centralized planning. The coordination can be modeled as:

$$\underset{\left\{{\pi }_k\right\}}{min}\sum _{k=1}^K{C}_k\left({\pi }_k\right)\mathrm{s}.\mathrm{t}.\mathrm{Coord}\left(\left\{{\pi }_k\right\}\right)=\mathrm{True}$$

where each agent’s plan ${\pi }_k$ must be compatible with others.

10.6. Algorithmic Example: Hierarchical Agent Planning

A recursive algorithm for hierarchical agent planning is described:

• functionHierarchicalPlan(goal)
•  if Atomic(goal) then
•   return Execute(goal)
•  else
•   subgoals ← Decompose(goal)
•   for all subgoal in subgoals do
•    result ← HierarchicalPlan(subgoal)
•   end for
•   return Aggregate(results)
•  end if
• end function

This comprehensive survey has examined the rapidly evolving landscape of AI agent frameworks and their transformative impact on financial services. Our analysis of 30+ recent publications (2024-2025) reveals three fundamental insights:

First, modern agent frameworks like LangGraph, CrewAI, and AutoGen have matured to support mission-critical financial applications, demonstrating 50-80% efficiency gains in data-intensive tasks such as risk assessment [40] and trade execution [5]. The emergence of specialized architectures for financial markets [33] and risk management [54] underscores the domain-specific optimization required for production deployment.

Second, successful adoption requires addressing four key challenges: (1) workforce transformation through AI upskilling [62], (2) risk alignment in autonomous decision-making [38], (3) regulatory compliance in sensitive financial operations [44], and (4) integration with legacy systems [20]. Cloud-native Python libraries [26] and modular frameworks [34] are lowering these barriers.

Third, our theoretical analysis establishes formal foundations for agentic AI in finance, including:

• Market microfoundations via agent-based modeling [33]
• Multimodal fusion for trading systems [5]
• Hierarchical risk assessment frameworks [6]

Future work should prioritize: (1) standardization of agent communication protocols, (2) development of testing benchmarks for financial agent systems, and (3) hybrid architectures combining human expertise with agent autonomy [65]. As the field progresses, the principles outlined in this survey will help financial institutions navigate the transition from experimental deployments to production-scale agentic AI solutions [61].

12.1. Challenges and Future Directions

Future work will focus on addressing the identified challenges, including scalability, real-time performance, regulatory compliance, and integration with existing systems. The use of AI agents in areas like wealth management [68] is a promising avenue for future research.

Deploying agentic AI in finance presents challenges such as integration with legacy systems, ensuring compliance, and managing operational risks [20,23,69]. There is also a need for standardization and best practices to ensure reliability and trustworthiness [60]. Open-source initiatives and cloud-native platforms are accelerating innovation but require careful evaluation for production use [21,70,71].
