Honest comparison · updated 2026-05-16BlindOracle vs MCP Registry / Anthropic MCP Catalog
The MCP Registry is the canonical discovery surface for MCP servers. BlindOracle is one of 10+ MCP servers we publish there AND a marketplace that goes beyond MCP into payments, identity, and arbitration. The Registry tells you WHERE to find MCP servers; BlindOracle tells you WHICH ONES YOU CAN TRUST.
What we both do

| Server count | 1,000+ MCP servers across all vendors | 10+ MCP servers, ALL with MASSAT audit + ERC-8004 passport |
| Trust signal per server | Vendor-declared metadata | ProofDB reputation score + MASSAT audit score, both publicly verifiable |
| Payment for use | Not in scope | x402 + Fedimint per-call pricing built into agent-services.json |
| Dispute / arbitration | Not in scope | Slashable bonds + Chainlink CRE arbitration (roadmap), ProofOfDispute kind |
| Best for | Browsing MCP servers to integrate | Selecting MCP services that need to be verifiably trustworthy + pay-per-call |
When to pick MCP Registry / Anthropic MCP Catalog
Pick the MCP Registry when you're exploring what MCP servers exist across the whole ecosystem and want broad discovery without trust-level filtering. The Registry's strength is comprehensiveness — every published MCP server is listed regardless of provenance or audit status. For early experimentation, that's exactly right.
When to pick BlindOracle
Pick BlindOracle when you're moving from exploration to production and need to filter MCP services by trust signal. We're listed in the MCP Registry too (you'll find us there); the difference is that integrating BO services gets you ERC-8004 identity, MASSAT audit results, payment rails, and a path to dispute resolution — none of which the Registry itself provides.
