[mcp-agent](https://github.com/lastmile-ai/mcp-agent) reports 8.5k GitHub stars, 879 forks, and 134 open issues, last pushed Jan 25, 2026. [agent-kernel](https://kernel.yaala.ai/) has 113 stars, 60 forks, and 128 open issues, last pushed Aug 7, 2026. Figures are from public GitHub metadata via [mcp-agent's repository](https://github.com/lastmile-ai/mcp-agent) and [agent-kernel's repository](https://github.com/yaalalabs/agent-kernel). | | [mcp-agent](/tools/lastmile-ai-mcp-agent.md) | [agent-kernel](/tools/yaalalabs-agent-kernel.md) | | --- | --- | --- | | Tagline | Build effective AI agents with Model Context Protocol. | The Operating System for Scalable Enterprise AI Agents | | Stars | 8,518 | 113 | | Forks | 879 | 60 | | Open issues | 134 | 128 | | Language | Python | Python | | Adopt for | Allows creation of efficient AI agents via Model Context Protocol with workflow patterns | Agent-kernel provides an operating system for scalable enterprise AI agents, supporting deployment and orchestration at scale with native integration support for MCP and A2A. | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | Apache-2.0 | | Categories | AI Agents | AI Agents | ## Trust and health _Sourced signals - not a safety guarantee.

See the comparison table for live GitHub stats and shared categories. ### When should I choose mcp-agent over agent-kernel? Choose mcp-agent over agent-kernel when Tags unique to mcp-agent: agents, ai-agents, llm, mcp; Need to implement the Model Context Protocol specifically in your agent development; More GitHub stars (8.5k vs 113) - visibility, not fit. ### When should I choose agent-kernel over mcp-agent? Choose agent-kernel over mcp-agent when Requirements: It requires Python versions between 3.12 and 3.13.x.; Supports deployment to various environments such as AWS Lambda, ECS, Azure Functions, or Container Apps via one Terraform module.; Tags unique to agent-kernel: a2a, adk, aws, azure; If you require seamless scalability across different cloud providers like AWS and Azure without lock-in or rewrites. ### When should I avoid mcp-agent? Require a more customizable approach beyond pre-defined protocol and workflows Project demands specific AI frameworks unsupported by Model Context Protocol directly ### When should I avoid agent-kernel? If your project is confined to a single, specific AI framework which doesn't require the flexibility Agent-kernel offers. When you do not have Python version 3.12 - 3.13.x, as it's the required runtime environment. ### Is mcp-agent or agent-kernel more popular on GitHub? mcp-agent has more GitHub stars (8,518 vs 113). Stars measure visibility, not whether either tool fits your constraints. ### Are mcp-agent and agent-kernel open source? Yes - both are open-source projects on GitHub (mcp-agent: Apache-2.0, agent-kernel: Apache-2.0). ### Where can I find alternatives to mcp-agent or agent-kernel? GraphCanon lists graph-backed alternatives at [mcp-agent alternatives](/tools/lastmile-ai-mcp-agent/alternatives) and [agent-kernel alternatives](/tools/yaalalabs-agent-kernel/alternatives) ([mcp-agent markdown twin](/tools/lastmile-ai-mcp-agent/alternatives.md), [agent-kernel markdown twin](/tools/yaalalabs-agent-kernel/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/lastmile-ai-mcp-agent-vs-yaalalabs-agent-kernel.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, mcp-agent or agent-kernel? mcp-agent: Slowing. agent-kernel: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for mcp-agent and agent-kernel? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [mcp-agent trust report](/tools/lastmile-ai-mcp-agent/trust); [agent-kernel trust report](/tools/yaalalabs-agent-kernel/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=lastmile-ai-mcp-agent`](/api/graphcanon/graph?tool=lastmile-ai-mcp-agent) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
