Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`BURNBOUND_KEY` Required, secret	Agent key (bb_agent_…) created in the Burnbound dashboard. Sent only to the Burnbound API.
`BURNBOUND_API` Optional	Burnbound API base URL. https:// only (http:// only for loopback). Set it for a self-hosted or local API.
`BURNBOUND_AGENT_ID` Optional	Only with an org key instead of an agent key: the agent the tools act for. Ignored with an agent key.
`BURNBOUND_WALLET_PROFILE` Optional	Local wallet profile for client-side signing (created with `npx -y @burnbound/mcp wallet init`). 1–32 of a-z, 0-9, _ and -.
`BURNBOUND_HOME` Optional	Directory for the local wallet file when the OS keychain is not used.
`BURNBOUND_MAX_RESPONSE_BYTES` Optional	fetch_paid response body cap in bytes (maximum 10485760). Longer bodies are truncated.
`BURNBOUND_FETCH_TIMEOUT_MS` Optional	fetch_paid deadline for the whole exchange with the URL, between 1000 and 120000 ms.
`BURNBOUND_APP_URL` Optional	Origin of the Burnbound panel, for the approval link a held payment returns (and opens in clients with URL-mode elicitation). Default: the API origin when it is https. https:// only.
`BURNBOUND_APPROVAL_WAIT_MS` Optional	How long fetch_paid waits for the human's decision once the approval page is opened from the chat, between 0 and 50000 ms. 0 returns pending_approval at once.
`BURNBOUND_BASE_RPC_URL` Optional	diagnose_payment: Base RPC used to read the paying wallet's USDC balance. https:// only. Only the wallet address is sent to it.
`BURNBOUND_BASE_SEPOLIA_RPC_URL` Optional	diagnose_payment: Base Sepolia RPC used to read the paying wallet's USDC balance. https:// only.
