Cryptography

SHA256, RIPEMD160, Hash160, Hash256, ECDSA signing/verification

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

// WHEN AI AGENTS USE THIS TOOL

AI agents use Cryptography to create or modify resources in Mcp Python Bitcoinlib. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON CRYPTOGRAPHY

Without a policy, an AI agent could call Cryptography repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Python Bitcoinlib.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the Cryptography tool do? +

SHA256, RIPEMD160, Hash160, Hash256, ECDSA signing/verification. It is categorised as a Write tool in the Mcp Python Bitcoinlib MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on Cryptography? +

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

What risk level is Cryptography? +

Cryptography is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit Cryptography? +

Yes. Add a rate_limit block to the Cryptography 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 Cryptography completely? +

Set action: deny in the Intercept policy for Cryptography. 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 Cryptography? +

Cryptography is provided by the Mcp Python Bitcoinlib MCP server (mcp-python-bitcoinlib). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
