AI agents call get_contexts to retrieve information from OCD - Organized Context Datastore (MCP) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves stored context data using glob patterns as filters. It performs no write, delete, or execution operations—it only reads from the structured Markdown file hierarchy. The low severity reflects minimal blast radius: misuse would only expose stored data within the datastore, not modify or delete it.
From the tool's definition Tool name 'get_contexts' and description indicating retrieval with patterns/filters ('パターンとフィルタでコンテキストを取得します' = 'Get contexts with patterns and filters'). The glob pattern parameters confirm query-based data retrieval with no mutation.

Register the OCD - Organized Context Datastore (MCP) MCP server in PolicyLayer and add a rule for get_contexts: 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 OCD - Organized Context Datastore (MCP). Nothing to install.
get_contexts 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_contexts 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_contexts. 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_contexts is provided by the OCD - Organized Context Datastore (MCP) MCP server (teamstove/organized-context-datastore-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
