Convert Markdown to BBCode format. Transforms formatting to [b], [i], [s], [code], [url], [img] tags. Used for forum posts on phpBB, vBulletin, and similar platforms.
Part of the Markdown MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use convert_to_bbcode to create or modify resources in Markdown. 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 convert_to_bbcode 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 Markdown.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
