Returns custom guidelines, best practices, and example queries defined in instructions.md.
AI agents call get_custom_instructions to retrieve information from SQLite MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns read-only instructional content from a markdown file. It performs data retrieval without modifying, executing code, deleting, or causing financial impact. The worst-case misuse would be information disclosure of internal guidelines, which is low severity. Confidence is high because the description clearly indicates a retrieval operation on static documentation.
From the tool's definition Tool name 'get_custom_instructions' and description 'Returns custom guidelines, best practices, and example queries' indicate retrieval of static instruction/documentation data with no side effects.
Attacks that exploit this kind of access
Returns custom guidelines, best practices, and example queries defined in instructions.md. It is categorised as a Read tool in the SQLite MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SQLite MCP Server MCP server in PolicyLayer and add a rule for get_custom_instructions: 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 SQLite MCP Server. Nothing to install.
get_custom_instructions 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 get_custom_instructions 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 get_custom_instructions. 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.
get_custom_instructions is provided by the SQLite MCP Server MCP server (u1pns/sqlite-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
