Warning

Financial risk: package may sign and pay for calls or buy tokens. Never use production wallet/private key to test. Obtain explicit spending approval.
A private key is not an API key; do not expose it in project files, screenshots, logs, or chat transcripts.
Chargeable by default for tool invocation: per-call USDC/x402 pricing. Tool listing or MCP registration is not a free-use guarantee.
Literal command/entry path confirmed against official README; does not validate runtime or host compatibility.
Prior reviewed safety note: Do not treat starting the MCP process as consent to transact.
Prior reviewed safety note: Do not invoke any tool merely to confirm connectivity: publisher prices its tools per call in USDC.
Prior reviewed safety note: Do not supply or fund X402_PRIVATE_KEY for initial registration.
Prior reviewed safety note: Do not delete user data or assume this cancels upstream authorizations.
Client removal, software uninstall, persistent-data deletion and credential revocation are separate actions.

Publisher-documented install or connect path; prerequisites and any extra host configuration remain required.

Configure / authenticate
MCP100 setup guide
Register local stdio MCP JSON with command npx and args ["-y","@agentutility/mcp-bestiary"], env X402_PRIVATE_KEY. Publisher requires funded Base USDC wallet for paid x402 calls; DO NOT substitute an API key or include private key in public config.
Check connection
Suggested check
Confirm MCP registration and tool discovery only. Calling tools can charge USDC; do not call a paid tool for verification.
Remove / uninstall / revoke
MCP100 setup guide
If registered in Claude Code under the name `agentutility-bestiary`, remove the client entry with `claude mcp remove agentutility-bestiary`. For other MCP hosts remove the matching server/connector in that host’s MCP settings. Remove a globally installed software package separately if applicable; this does not delete data or revoke a service credential.
Client removal, software uninstall, persistent-data deletion and credential revocation are separate actions.
Separate credential guidance (provider revocation is not verified): Publisher uses X402_PRIVATE_KEY for x402 USDC payments. Removing this variable or the MCP registration prevents new calls from this host but does not revoke the wallet private key. If exposed, rotate by creating a new wallet and handling any funds with wallet-provider guidance; no invented vendor revoke CLI.
