What problem does it solve?
You cannot tell whether an agent API’s micropayment price is reasonable or whether a receipt is authentic until you manually hunt benchmarks and crypto details.
Who is it for?
Indie builders evaluating or operating x402/MPP-paid agent services who want agent-assisted price and receipt checks from the IDE.
Skip if: Teams that do not use micropayment agent protocols or who need full billing, invoicing, or merchant onboarding in one tool.
What do I get? / Deliverables
Your agent can query ARI for price context, leaderboards, and verified receipts while you scope and operate paid MCP integrations.
- Fair-price assessment context for target x402/MPP services
- Leaderboard-ranked provider comparisons from ARI
- Ed25519 receipt verification results for agent payment proofs
Recommended MCP Servers
Journey fit
Pricing validation belongs in Validate because indie builders should sanity-check micropayment and per-call costs before committing integrations. Fair-price leaderboards and receipt checks directly support pricing decisions for agent-paid APIs.
How it compares
ARI pricing intelligence MCP, not a wallet or payment gateway implementation.
Common Questions / FAQ
Who is io.github.Antmanbuilds/ari-mcp for?
Solo and indie developers building agent products that pay for third-party MCP or API calls via x402/MPP and want fair-price context inside their agent.
When should I use io.github.Antmanbuilds/ari-mcp?
Use it while validating integration economics, comparing providers on leaderboards, or verifying Ed25519 receipts before trusting a paid agent call in production.
How do I add io.github.Antmanbuilds/ari-mcp to my agent?
Register the stdio server with runtimeHint npx and package identifier ari-mcp; set ARI_API_BASE_URL only if you need a non-default API host.
