Burnbound

dev.burnbound/mcpv0.7.0Other

Let your AI agent pay x402 APIs within daily caps, allowed hosts and human approval.

The current version, v0.7.0, was published to the official MCP registry on 2026-10-09. It is distributed as @burnbound/mcp on npm, filed under Other by this index, and declares 11 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.

In-path gate · all MCP tools

Using Burnbound in Claude, Cursor, Gemini CLI, Cline, or Zed?

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).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Semantic screen flagged a possible manipulation pattern in the description; review before your agent calls this tool.

held for reviewThe semantic screen raised a flag, but it has not been human-reviewed. It is held - not a confirmed finding - until a reviewer confirms or clears it.

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b
- The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not

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 Burnbound’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

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.

BURNBOUND_AGENT_ID

Only with an org key instead of an agent key: the agent the tools act for. Ignored with an agent key.

BURNBOUND_WALLET_PROFILE

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

Directory for the local wallet file when the OS keychain is not used.

BURNBOUND_MAX_RESPONSE_BYTES

fetch_paid response body cap in bytes (maximum 10485760). Longer bodies are truncated.

BURNBOUND_FETCH_TIMEOUT_MS

fetch_paid deadline for the whole exchange with the URL, between 1000 and 120000 ms.

BURNBOUND_APP_URL

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

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

diagnose_payment: Base RPC used to read the paying wallet's USDC balance. https:// only. Only the wallet address is sent to it.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 972,115). Verify it yourself.
