Identify inappropriate code-switching or language mixing
AI agents call multilingual.detect_language_mixing to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs linguistic analysis on input text to detect language mixing patterns. It retrieves or analyzes information about code-switching without modifying data, executing code, or causing irreversible changes. The worst-case misuse would be an AI agent generating false positives on language detection, which has minimal blast radius—purely informational impact. This clearly falls under the Read category.
From the tool's definition Tool name 'detect_language_mixing' and description 'Identify inappropriate code-switching or language mixing' indicate analysis and detection of existing content patterns. No creation, modification, execution, deletion, or financial operations are implied.

Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for multilingual.detect_language_mixing: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ContextForge MCP Gateway. Nothing to install.
multilingual.detect_language_mixing is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the multilingual.detect_language_mixing rule in your PolicyLayer 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 PolicyLayer policy for multilingual.detect_language_mixing. 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.
multilingual.detect_language_mixing is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
