schnorr_sign_digest

Sign a raw 32-byte digest with Schnorr (BIP-340) using the wallet's Taproot private key. Use for Taproot script-path spending, multisig coordination, or any case where you need a BIP-340 Schnorr signature over a pre-computed hash (e.g., BIP-341 sighash).

Part of the Aibtc MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call schnorr_sign_digest to retrieve information from Aibtc without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though schnorr_sign_digest only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the schnorr_sign_digest tool do? +

Sign a raw 32-byte digest with Schnorr (BIP-340) using the wallet's Taproot private key. Use for Taproot script-path spending, multisig coordination, or any case where you need a BIP-340 Schnorr signature over a pre-computed hash (e.g., BIP-341 sighash). WARNING: This signs raw digests that cannot be human-verified — use confirmBlindSign=true after reviewing the digest. Returns a 64-byte signature and the x-only public key. Requires an unlocked wallet.. It is categorised as a Read tool in the Aibtc MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on schnorr_sign_digest? +

Add a rule in your Intercept YAML policy under the tools section for schnorr_sign_digest. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Aibtc MCP server.

What risk level is schnorr_sign_digest? +

schnorr_sign_digest is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit schnorr_sign_digest? +

Yes. Add a rate_limit block to the schnorr_sign_digest rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block schnorr_sign_digest completely? +

Set action: deny in the Intercept policy for schnorr_sign_digest. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides schnorr_sign_digest? +

schnorr_sign_digest is provided by the Aibtc MCP server (@aibtc/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
