Validate AI Agent Protocol Compliance
Test schemas, verify signatures, and check live endpoints before deployment. The trust layer for the agent-to-agent economy.
Three Validation Layers
Schema validation catches syntax errors. Production failures need deeper testing.
🌐Connectivity Testing
- •HTTP GET/POST to all declared endpoints
- •JSONRPC method availability checks
- •gRPC service reflection validation
🔒Signature Verification
- JWS detached signature validation
- JWKS key fetching and verification
- Ed25519/RSA algorithm support
📋Specification Compliance
- A2A v0.3.0 schema validation
- Required field presence checks
- Transport consistency validation
Common Validation Gaps
JSON schema validation doesn't catch runtime integration failures.
⚠️Schema-Valid But Broken
- •
transport.jsonrpcURL returns 404 - •
transport.grpcconnection refused - •Missing
signaturefield allows tampering - •Invalid
capabilities[].operationvalues
✓Capiscio Validation Tests
- •HTTP connectivity to all transport URLs
- •gRPC service reflection and method calls
- •JWS signature verification with JWKS
- •A2A v0.3.0 specification compliance

Technical Implementation
🔒 Cryptographic Stack
- • RFC 7515 JWS (JSON Web Signature)
- • RFC 7517 JWKS (JSON Web Key Set)
- • Ed25519 + RSA signature algorithms
- • HTTPS-only key distribution
🌐 Protocol Support
- • JSON-RPC 2.0 method validation
- • gRPC reflection and health checks
- • HTTP/REST endpoint connectivity
- • A2A v0.3.0 specification compliance
Installation: npm, pip, or standalone binary. CI/CD: JSON output with proper exit codes.
Your Agent Lives in an Ecosystem
Your agent doesn't work in isolation—it depends on other agents you don't control. One broken dependency can break your entire integration.
Your Responsibility
- ✓Your agent card - Ensure protocol compliance
- ✓Your endpoints - Test live connectivity
- ✓Your signatures - Prove authenticity
capiscio validate ./my-agent.jsonTheir Responsibility (But Your Risk)
- ?Third-party agents - Are they compliant?
- ?External endpoints - Are they actually reachable?
- ?Trust verification - Can you trust their claims?

But you CAN validate their protocol compliance before you depend on them. Catch broken integrations before they hit production—not after.

Installation & Usage
Install in One Command
npm install -g capiscio-clipip install capiscioAlso available as standalone binary (zero dependencies)
View all installation options & usage examples →Automated Quality Gates
Enforce validation in CI/CD with three-dimensional scoring and production readiness checks.
GitHub Action Available
Automate validation in your CI/CD pipeline with zero setup. The GitHub Action installs the CLI, runs validation, and exports three-dimensional scores for your workflow.
Don't Trust Third-Party Agents Blindly
Evaluate agent quality and compliance before integration. Avoid broken dependencies.
❌Without Validation
- •Integration breaks in production
- •Unknown compliance status
- •Transport protocol mismatches
- •Silent failures and timeouts
✓With Capiscio
- •Pre-integration quality assessment
- •A2A compliance scoring
- •Multi-transport compatibility check
- •Reliable integration confidence
