RagaAI-Catalyst: Python SDK for AI agent observability and evaluation. See the comparison table for live GitHub stats and shared categories. ### When should I choose mcp-trust-plane over RagaAI-Catalyst? Choose mcp-trust-plane over RagaAI-Catalyst when mcp-trust-plane is primarily JavaScript; RagaAI-Catalyst is Python; Pricing: MCP Trust Plane is open-source under Apache 2.0, making it available at no cost but provides flexibility to extend commercially through proprietary filter implementations.; Requirements: Min 1 GB RAM; Tags unique to mcp-trust-plane: access-control, ai-agents, data-governance-and-ai, data-security; mcp-trust-plane ships Docker support for self-hosted deployment; MCP Trust Plane should be used when you require granular control over tool calls in your MCP-enabled systems, such as enforcing PII redaction or operation blocking. ### When should I choose RagaAI-Catalyst over mcp-trust-plane? Choose RagaAI-Catalyst over mcp-trust-plane when RagaAI-Catalyst is primarily Python; mcp-trust-plane is JavaScript; Tags unique to RagaAI-Catalyst: agentic-ai, agentic-ai-development, agentneo, agents; When you need comprehensive tools for the observability of complex multi-agentic systems. ### When should I avoid mcp-trust-plane? Avoid MCP Trust Plane if your security needs do not require modification of traffic post-response, as it introduces an additional layer of complexity and latency. MCP Trust Plane may not be the best choice for environments that strictly enforce language-specific policies since its filters are written in any language and must comply with a strict contract. ### When should I avoid RagaAI-Catalyst?

If your primary need is focused solely on basic monitoring without advanced debugging and evaluation features. For projects that do not utilize multi-agentic systems or do not benefit from timeline and execution graph visualizations. In scenarios where a fully managed service with no self-hosting requirements is preferred. ### Is mcp-trust-plane or RagaAI-Catalyst more popular on GitHub? RagaAI-Catalyst has more GitHub stars (16,145 vs 59). Stars measure visibility, not whether either tool fits your constraints. ### Are mcp-trust-plane and RagaAI-Catalyst open source? Yes - both are open-source projects on GitHub (mcp-trust-plane: Apache-2.0, RagaAI-Catalyst: Apache-2.0). ### Where can I find alternatives to mcp-trust-plane or RagaAI-Catalyst? GraphCanon lists graph-backed alternatives at [mcp-trust-plane alternatives](/tools/abluva-research-mcp-trust-plane/alternatives) and [RagaAI-Catalyst alternatives](/tools/raga-ai-hub-ragaai-catalyst/alternatives) ([mcp-trust-plane markdown twin](/tools/abluva-research-mcp-trust-plane/alternatives.md), [RagaAI-Catalyst markdown twin](/tools/raga-ai-hub-ragaai-catalyst/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/abluva-research-mcp-trust-plane-vs-raga-ai-hub-ragaai-catalyst.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, mcp-trust-plane or RagaAI-Catalyst? mcp-trust-plane: Active. RagaAI-Catalyst: Slowing. 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-trust-plane and RagaAI-Catalyst? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [mcp-trust-plane trust report](/tools/abluva-research-mcp-trust-plane/trust); [RagaAI-Catalyst trust report](/tools/raga-ai-hub-ragaai-catalyst/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=abluva-research-mcp-trust-plane`](/api/graphcanon/graph?tool=abluva-research-mcp-trust-plane) - 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/_
