Implementation Reference

• src/index.ts:18-49 (handler)

  The MCP tool 'set_rules' implementation, which parses rules and stores them in the local 'rules' variable.

  server.tool(
    "set_rules",
    "Set covenant rules using permit/forbid/require syntax. Each rule is a string like 'forbid delete_user' or 'permit read_data safe to read'.",
    {
      rules: z.array(z.string()).describe(
        "Array of rule strings, e.g. ['forbid delete_user', 'permit read_data']"
      ),
    },
    async ({ rules: ruleStrings }) => {
      try {
        rules = ruleStrings.map(parseRule);
        return {
          content: [
            {
              type: "text" as const,
              text: JSON.stringify({ ok: true, count: rules.length, rules }, null, 2),
            },
          ],
        };
      } catch (err) {
        return {
          content: [
            {
              type: "text" as const,
              text: JSON.stringify({ ok: false, error: (err as Error).message }),
            },
          ],
          isError: true,
        };
      }
