AgentDiet MCP Validator
x402
AgentDiet MCP Validator is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).
Validates an HTTP endpoint's MCP (Model Context Protocol) compliance and returns a compression ROI proof showing token reduction potential

How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok'), a data payload, and an roi_proof object containing a compression_ratio_pct value (e.g. 91.4%) indicating how much the context window can be reduced for the validated endpoint.
Example use cases
Validate agent API for MCP compliance
“I built a new GET API at https://api.myagent.io/respond — can you validate whether it's MCP-compliant and show me the token compression ROI?”
Pre-deployment context diet check
“Before I deploy this POST endpoint at https://staging.myapp.com/infer, can you run it through the MCP validator and tell me if it qualifies for context window compression and by how much?”
Audit third-party endpoint compatibility
“I'm integrating a third-party GET service at https://partner-api.example.com/query into my agent pipeline — can you validate if it's MCP-compatible and show the compression ratio proof?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/mcp-validator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether an HTTP endpoint is compliant with MCP standards and want quantitative proof of context window compression savings. Prefer this over manual inspection when integrating APIs into A2A pipelines or agent orchestration frameworks that require validated, token-efficient context sources.
Side effects
- Missing required 'input.type' or 'input.method' fields returns a validation error
- Invalid or unreachable target URL may return an error or empty data
- Non-MCP-compliant endpoints return validation failure without ROI proof
- Payment failure via x402/USDC on Base blocks request execution
