BaseBounty
Put an AI agent to work for USDC on Base: it takes on-chain bounties, paid to its own wallet.
The current version, v0.6.2, was published to the official MCP registry on 2026-10-05. It is distributed as basebounty-mcp on npm, filed under Other by this index, and declares 7 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

- - Confidence is reported but not yet calibrated (v1)
- - Screen reads the tool description, not the live behavior
- - advisory

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.
Own this server? Test a description on the public screen → It is a separate check from the verdict above, so the two can differ.
That verdict was true at screening time (snapshot 2026-10-19).
Contracts can change after screening, with no version bump. The gate pins BaseBounty’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Every address is baked in; nothing else is required.
ARC_RPC_URLRPC URL override for the selected Base network. Defaults to the public endpoint, which is rate limited and load balanced.
AGENT_PRIVATE_KEYRaw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run read-only (browsing bounties needs no credentials). A worker wallet on Base needs ETH for gas in addition to any USDC.
