Connect DefaultBench and your agent gets 13 tools, among them compare_resources, complete_seller_analytics_challenge, get_claim_status. It answers at https://defaultbench.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 5 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Search transparent sponsored listings for agents, APIs, tools, and MCP servers.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
compare_resources | Compare declared fields and objective bounded evidence side by side without changing sponsored ordering. Inputs: resources |
complete_seller_analytics_challenge | Consume one wallet-signed challenge and return a listing-bound five-minute bearer token. Inputs: listing_id, challenge_id, wallet_signature |
get_claim_status | Return the current time-limited domain and wallet controller link. Claim status does not affect paid rank or quality. Inputs: resource_id |
get_discovery_sources | Return non-secret synchronization freshness, state, and active/stale counts for approved organic sources. |
get_evidence_history | Return declared provenance plus timestamped bounded conformance and reliability observations. Evidence is not trust, safety, quality, or endorsement. Inputs: subject_type, id, limit, cursor |
get_listing | Return one paid listing, its current rank, verified payer identity, and declared machine endpoints. Inputs: id |
get_seller_analytics | Read one listing's aggregate funnel, spend, rank history, freshness and time series using a short-lived listing-bound token. Inputs: listing_id, access_token, from, to, granularity |
get_seller_analytics_challenge | Create a one-time EIP-712 challenge for the listing's verified payer or current verified controller. This creates no account or cookie. Inputs: listing_id, wallet_address |
inspect_keyword | Return the keyword summary and deterministic ranking ordered by cumulative verified payment. Inputs: keyword, limit, cursor |
inspect_organic_resource | Return the intact unpaid imported record, source provenance, and current verified-controller link if one exists. Inputs: id |
quote_rank | Calculate informational minimum additions for higher positions. Final rank is determined at settlement. Inputs: keyword, wallet |
search_agents | Search local inventory. Sponsored listings include paid rank and cumulative verified bid; organic resources are separate unpaid external records with source provenance. Inputs: query, limit, cursor, organic_cursor, sort, source |
validate_organic_resource | Read-only validation of source provenance, canonical endpoint, and current controller state. It never creates a listing or payment. Inputs: resource_id |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://defaultbench.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.nathanyoshua. Endpoint host: defaultbench.com. ARD identifier: urn:air:io.github.nathanyoshua:mcp:defaultbench.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
