Data-driven analysis of custom AI SDK market expansion, implementation success rates, and the infrastructure powering enterprise tool-calling applications
Custom SDK implementations have become the backbone of AI-powered applications, with the agentic AI developer ecosystem projected to grow from $6.96 billion in 2025 to $42.56 billion by 2030. This explosive growth reflects enterprise demand for governed tool execution that goes beyond basic API integrations. Arcade.dev addresses this directly as the MCP runtime that enables and governs multi-user authorization—so agents can take real actions with fine-grained, delegated user permissions and scoped access across a tool catalog of hundreds of enterprise platforms (plus custom tools). Arcade provides token and secret management (not data handling), which dramatically reduces the risk and engineering burden of building safe tool execution at scale.

AI SDK Market Size and Growth Statistics
1. Agentic AI developer ecosystem reaches $6.96 billion in 2025
The market for AI agent development tools and SDKs hit $6.96 billion in 2025, with projections showing growth to $42.56 billion by 2030 at 43.61% CAGR. This acceleration reflects enterprise investment in autonomous AI systems capable of executing real-world actions. Arcade positions teams to capture this growth by standardizing multi-user authorization and token/secret management across tools—so reaching production doesn’t require rebuilding permission logic for every workflow.
For leaders, the impact lands across three groups: AI/ML teams ship automation faster because authorization doesn’t have to be rebuilt per tool; security teams get consistent scope boundaries and auditability for every action; and business teams see faster time-to-value because agents can safely execute real workflows without over-permissioning or brittle glue code.
2. AI software platform market expands to $26.65 billion
The broader AI software platform market reached $26.65 billion in 2025, with forecasts projecting $88.19 billion by 2034 at a 14.22% CAGR. Software tools and SDKs represent the largest component of this market, commanding a 52% share valued at $12.14 billion.

Implementation Best Practices
Without Arcade, organizations typically have to build and continuously maintain their own multi-user authorization layer across tools—mapping scopes, handling token/secret management, preventing over-permissioning, and producing auditability—which becomes brittle and expensive as tool coverage expands.
Successful custom SDK implementations follow established patterns that maximize ROI while minimizing risk:
Architecture priorities:
- Design for multi-agent coordination from the start
- Implement zero-trust multi-user authorization architectures
- Build comprehensive error handling and retry logic
- Create audit trails for all tool executions
Development workflow integration:
- Use pre-built connectors where available to reduce development time
- Leverage delegated user permissions and scoped access providers for industry-standard multi-user authorization
- Validate that delegated scopes, approvals, and audit trails are correct for the single initial production use case
Security considerations:
- Encrypt tokens at rest and in transit
- Implement least-privilege access patterns
- Avoid storing credentials in application code
- Use just-in-time authorization for sensitive operations
Future Projections and Investment Priorities
The trajectory of custom SDK adoption shows sustained acceleration through 2030 and beyond. With multi-agent systems growing at 44.23% CAGR and enterprise spending increasing annually, organizations must prepare infrastructure and teams for expanded AI tool-calling implementations.
Strategic investment areas:
- Scalable infrastructure: Prepare for 10x growth in tool-calling volume
- Security frameworks: Implement zero-trust architectures for API access
- Operating model: standardize governance, approvals, and audit review for high-impact agent actions
- Integration strategies: Plan systematic rollout across business functions
Emerging technology trends:
- Model Context Protocol (MCP) standardization for tool invocation
- Agent-to-agent (A2A) communication protocols
- Edge AI integration for real-time applications
