Problem

Teams building AI agents use diverse inter-agent messaging standards—MCP, A2A, custom protocols—leading to frequent integration failures from message format mismatches. On average, 30–40% of agent integration development time is spent debugging message parsing errors, primarily caused by JSON schema mismatches, missing fields, and encoding issues.

Solution

Agent message schema validation & debugging SaaS. (1) Automatic message schema validation for major protocols including MCP/A2A, (2) real-time message stream capture with error highlighting, (3) cross-protocol message conversion preview. The differentiation: what Postman does for HTTP APIs, this does for agent messaging protocols.

Target: AI agent development startups (3–20 employees), Freelancer AI engineers, LLM-based service development teams
Revenue Model: Premium SaaS — Free (1,000 validations/month), Pro ~$22/month (unlimited validations + conversions), Team ~$67/month (5 users + team dashboard).
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
