Part of the Ccboot MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use ccboot_create_security_hook to create or modify resources in Ccboot. 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.
Without a policy, an AI agent could call ccboot_create_security_hook 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 Ccboot.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Generates a comprehensive security hook system that blocks dangerous commands and detects secret leaks before they happen. Creates a blocker script and hooks it into Claude Code's PreToolCall lifecycle. Strictness levels: • standard: Blocks rm -rf, force push, DROP TABLE, TRUNCATE (8 patterns) • strict: + git reset --hard, chmod 777, curl|sh, wget|sh (13 patterns) • paranoid: + eval(), exec(), sudo, su, pkill, killall (19 patterns) Also detects secret patterns: AWS keys, API keys, GitHub tokens, private keys. Examples: ccboot_create_security_hook({ project_path: '.', strictness: 'standard' }) ccboot_create_security_hook({ project_path: '.', strictness: 'paranoid' }) Idempotent: Updates existing security hook if present.. It is categorised as a Write tool in the Ccboot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for ccboot_create_security_hook. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ccboot MCP server.
ccboot_create_security_hook is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ccboot_create_security_hook 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.
Set action: deny in the Intercept policy for ccboot_create_security_hook. 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.
ccboot_create_security_hook is provided by the Ccboot MCP server (ccboot-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
